Description
本発明は、溶融金属の流量制御のために使用されるスライディングノズル装置に関し、特に、固定金枠の長辺側の両側にスライド金枠保持部を開閉可能に備えるスライディングノズル装置に関する。
The present invention relates to a sliding nozzle device used for controlling the flow rate of molten metal, and more particularly, to a sliding nozzle device provided with slide metal frame holding parts that can be opened and closed on both long sides of a fixed metal frame.
スライディングノズル装置は、例えば取鍋の溶鋼排出口部に取り付けられ、ノズル孔を有する上下２枚の耐火物製のプレートを重ねて面圧を負荷した状態で、その下プレートを上プレートに対して直線的に摺動させてノズル孔の開度を変化させることで溶鋼（溶融金属）の流量を制御している。
The sliding nozzle device is attached to, for example, a molten steel discharge port of a ladle, and in a state where a surface pressure is applied by overlapping two refractory plates having upper and lower nozzle holes, the lower plate is placed against the upper plate. The flow rate of the molten steel (molten metal) is controlled by sliding linearly and changing the opening of the nozzle hole.
このようなスライディングノズル装置は一般的に、上プレートを保持する固定金枠と、下プレートを保持し当該下プレートを上プレートに対して摺動させるために直線的にスライドするスライド金枠と、スライド金枠をスライド可能に保持するスライド金枠保持部と、上下のプレート間に面圧を負荷するための弾性体と、スライド金枠を駆動するための駆動装置とを有する。
Such a sliding nozzle device generally has a fixed metal frame that holds the upper plate, a slide metal frame that holds the lower plate and slides linearly to slide the lower plate relative to the upper plate, It has a slide metal frame holding part that slidably holds the slide metal frame, an elastic body for applying a surface pressure between the upper and lower plates, and a drive device for driving the slide metal frame.
一般的にはスライド金枠保持部は１つであるが、小型化を目的に２つに分割されたタイプもある。例えば特許文献１では、図８及び図９に示しているように、開閉金枠（スライド金枠保持部）４０はスライド金枠３０のスライド方向中心線に対して対称に２つ設けられており、それぞれ固定金枠２０に取り付けられている。スライド金枠保持部４０は、門型アーム４１、バネボックス４２、面圧ガイド４８、及び摺動部材４６を備える。具体的には、固定金枠２０に設けたピン２２に対して門型アーム４１の基端部を回動可能に取り付け、門型アーム４１のアーム４１ａ間にバネボックス４２を配置し、このバネボックス４２に面圧ガイド４８を一体的に設けている。
Generally, there is one slide metal frame holding part, but there is also a type divided into two for the purpose of miniaturization. For example, in Patent Document 1, as shown in FIGS. 8 and 9, two opening / closing metal frames (slide metal frame holding portions) 40 are provided symmetrically with respect to the center line in the slide direction of the slide metal frame 30. These are attached to the fixed metal frame 20, respectively. The slide metal frame holding unit 40 includes a portal arm 41, a spring box 42, a surface pressure guide 48, and a sliding member 46. Specifically, the base end portion of the portal arm 41 is rotatably attached to the pin 22 provided on the fixed metal frame 20, and a spring box 42 is disposed between the arms 41a of the portal arm 41. A surface pressure guide 48 is integrally provided in the box 42.
このスライディングノズル装置では、プレート交換時に２つのスライド金枠保持部をそれぞれ外側に開いた後、閉じる作業が必要となる。
しかし、プレート交換時にこのスライディングノズル装置を横置きにし、２つのスライド金枠保持部が上下に位置するようにしてこれら２つのスライド金枠保持部を開く場合、上側のスライド金枠保持部は自重（重力）に逆らって開く必要があるため作業者の負担となり、しかも開いても自重のため回動してもとに戻ってしまう。また、下側のスライド金枠保持部は自重のため回動して勝手に開くため危険であり、閉じる際には自重に逆らって閉じる必要があるため作業者の負担となり、しかも自重による戻りの問題もある。そして、このような自重によるスライド金枠保持部の回動を避けるためにはフックなどで固定しなければならず作業の手間が増える問題がある。 In this sliding nozzle device, it is necessary to open the two slide metal frame holding portions on the outside and then close the plates when exchanging the plates.
However, when the sliding nozzle device is placed horizontally when the plate is replaced and the two slide metal frame holding parts are opened so that the two slide metal frame holding parts are positioned above and below, the upper slide metal frame holding part is Since it is necessary to open against (gravity), it is a burden on the operator, and even if it opens, it returns to its original position even if it rotates due to its own weight. Also, the lower slide metal frame holding part is dangerous because it rotates by its own weight and opens freely, and it is necessary to close against the dead weight when closing, and it is burdensome for the operator, and the return due to its own weight There is also a problem. And in order to avoid such a rotation of the slide metal frame holding part due to its own weight, it has to be fixed with a hook or the like, and there is a problem that the labor of the work increases.

以下、図面に示す実施例に基づき本発明の実施の形態を説明する。
Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings.
＜第１の実施例＞
この実施例は、特許文献１すなわち図８及び図９のスライディングノズル装置をもとに本発明を適用したものである。従来、スライド金枠保持部はピン２２に回動可能に保持されていたが、この実施例では図１～３に示すように、ピンはシャフト５ａとして下側のスライド金枠保持部４ａと一体化し、このシャフト５ａが固定金枠２の２つのシャフト保持部６で回動可能に保持されている。このシャフト５ａはネジ６１によってスライド金枠保持部４ａの門型アーム４１ａと一体化して、このシャフト５ａの端部には第１リンク部７ａが設けられている。
また、上側のスライド金枠保持部４ｂにはシャフト５ｂが一体化して設けられており、このシャフト５ｂの端部には第２リンク部７ｂが設けられている。
すなわち、両側のシャフト５ａ、５ｂにそれぞれ円盤形状をした第１リンク部７ａと第２リンク部７ｂとが取り付けられ、それぞれのリンク部にはシャフトの中心軸に対して偏心した位置に連結部としてピン７１ａ、７１ｂが突設されている。これらのピン７１ａ、７１ｂには、リンク手段として１本のリンクバー１０の両端部がそれぞれピン７１ａ、７１ｂに回動可能に取り付けられている。そしてこのリンクバー１０はそれぞれのシャフト５ａ、５ｂの中心軸を結ぶ直線と交差し、またそれぞれのシャフト５ａ、５ｂの中心とそれぞれのピン７１ａ、７１ｂとの距離は同じ長さである。 <First embodiment>
In this embodiment, the present invention is applied based onPatent Document 1, that is, the sliding nozzle device shown in FIGS. Conventionally, the slide metal frame holding portion is rotatably held by the pin 22, but in this embodiment, as shown in FIGS. 1 to 3, the pin is integrated with the lower slide metal frame holding portion 4a as a shaft 5a. The shaft 5 a is rotatably held by the two shaft holding portions 6 of the fixed metal frame 2. The shaft 5a is integrated with the portal arm 41a of the slide metal frame holding portion 4a by a screw 61, and a first link portion 7a is provided at the end of the shaft 5a.
The upper slide metalframe holding portion 4b is integrally provided with a shaft 5b, and a second link portion 7b is provided at an end of the shaft 5b.
That is, thefirst link portion 7a and the second link portion 7b each having a disk shape are attached to the shafts 5a and 5b on both sides, and each link portion is connected to a position eccentric with respect to the central axis of the shaft. Pins 71a and 71b are projected. Both ends of one link bar 10 are rotatably attached to these pins 71a and 71b as link means. The link bar 10 intersects a straight line connecting the central axes of the shafts 5a and 5b, and the distance between the centers of the shafts 5a and 5b and the pins 71a and 71b is the same.
この実施例は、特許文献１すなわち図８及び図９のスライディングノズル装置をもとに本発明を適用したものである。従来、スライド金枠保持部はピン２２に回動可能に保持されていたが、この実施例では図１～３に示すように、ピンはシャフト５ａとして下側のスライド金枠保持部４ａと一体化し、このシャフト５ａが固定金枠２の２つのシャフト保持部６で回動可能に保持されている。このシャフト５ａはネジ６１によってスライド金枠保持部４ａの門型アーム４１ａと一体化して、このシャフト５ａの端部には第１リンク部７ａが設けられている。
また、上側のスライド金枠保持部４ｂにはシャフト５ｂが一体化して設けられており、このシャフト５ｂの端部には第２リンク部７ｂが設けられている。
すなわち、両側のシャフト５ａ、５ｂにそれぞれ円盤形状をした第１リンク部７ａと第２リンク部７ｂとが取り付けられ、それぞれのリンク部にはシャフトの中心軸に対して偏心した位置に連結部としてピン７１ａ、７１ｂが突設されている。これらのピン７１ａ、７１ｂには、リンク手段として１本のリンクバー１０の両端部がそれぞれピン７１ａ、７１ｂに回動可能に取り付けられている。そしてこのリンクバー１０はそれぞれのシャフト５ａ、５ｂの中心軸を結ぶ直線と交差し、またそれぞれのシャフト５ａ、５ｂの中心とそれぞれのピン７１ａ、７１ｂとの距離は同じ長さである。 <First embodiment>
In this embodiment, the present invention is applied based on
The upper slide metal
That is, the
図３に示すように両側のスライド金枠保持部４ａ、４ｂが閉じた状態では、第１リンク部７ａのピン７１ａは９時の位置にあり、第２リンク部７ｂのピン７１ｂは３時の位置にあり、これらのリンク部（ピン７１ａ、７１ｂ）どうしは、縦断面においてそれぞれのシャフト５ａ、５ｂの中心軸間を結ぶ直線の中心に対して点対称の位置関係になっている。
As shown in FIG. 3, when the slide metal frame holding portions 4a and 4b on both sides are closed, the pin 71a of the first link portion 7a is at the 9 o'clock position, and the pin 71b of the second link portion 7b is at the 3 o'clock position. These link portions ( pins 71a and 71b) are in a position symmetrical with respect to the center of a straight line connecting the central axes of the shafts 5a and 5b in the longitudinal section.
図５は、第１リンク部７ａの連結部（ピン７１ａ）とリンクバー１０との連結位置の調節機構の説明図である。リンクバー１０に長孔１０ａを有し、ネジ１０ｂがリンクバー１０の端部から螺合して、その先端部１０ｂ－１が長孔１０ａ内に突出している。このネジ１０ｂの先端部１０ｂ－１はコの字型をしておりピン７１ａを挟んでいる。すなわち、ネジ１０ｂを進退させることによりピン７１ａとリンクバー１０との連結位置が変化するため、第１リンク部７ａ（ピン７１ａ）と第２リンク部７ｂ（ピン７１ｂ）との連結長さが調節可能になっている。
FIG. 5 is an explanatory diagram of a mechanism for adjusting the connecting position between the connecting portion (pin 71a) of the first link portion 7a and the link bar 10. As shown in FIG. The link bar 10 has a long hole 10a, the screw 10b is screwed from the end of the link bar 10, and the tip 10b-1 projects into the long hole 10a. The tip 10b-1 of the screw 10b has a U-shape and sandwiches the pin 71a. That is, since the connecting position between the pin 71a and the link bar 10 is changed by moving the screw 10b back and forth, the connecting length between the first link portion 7a (pin 71a) and the second link portion 7b (pin 71b) is adjusted. It is possible.
次に、この実施例においてスライド金枠保持部４ａ、４ｂの開閉機構について説明する。図３において上側のスライド金枠保持部４ｂを開くとシャフト５ｂに設けられた第２リンク部７ｂが矢印方向（時計回り方向）に回転し、これに伴い第１リンク部７ａは反対の矢印方向（反時計回り方向）に回転するので下側のスライド金枠保持部４ａも連動して同時に開くことができる（図４の状態）。
Next, the opening / closing mechanism of the slide metal frame holding portions 4a and 4b in this embodiment will be described. In FIG. 3, when the upper slide metal frame holding portion 4b is opened, the second link portion 7b provided on the shaft 5b rotates in the direction of the arrow (clockwise direction), and accordingly, the first link portion 7a is in the opposite arrow direction. Since it rotates in the counterclockwise direction, the lower slide metal frame holding portion 4a can be simultaneously opened in conjunction with it (state shown in FIG. 4).
また、スライド金枠保持部４ａ、４ｂを閉じる際は、上側のスライド金枠保持部４ｂを閉じると、第１リンク部７ａが第２リンク部７ｂとは逆方向に回転するので下側のスライド金枠保持部４ｂを連動して同時に閉じることができる。両側のスライド金枠保持部４ａ、４ｂを閉じた後は、スライド金枠保持部４ａ、４ｂから固定金枠へ繋がる貫通孔にストッパーピンを挿入して、スライド金枠保持部４ａ、４ｂが完全に閉じたことを確認する。
Further, when closing the slide metal frame holding portions 4a and 4b, if the upper slide metal frame holding portion 4b is closed, the first link portion 7a rotates in the opposite direction to the second link portion 7b, so that the lower slide The metal frame holding part 4b can be simultaneously interlocked and closed. After closing the slide metal frame holding parts 4a and 4b on both sides, a stopper pin is inserted into the through hole that connects the slide metal frame holding parts 4a and 4b to the fixed metal frame, and the slide metal frame holding parts 4a and 4b are completely Confirm that it was closed.
本発明では、２つのスライド金枠保持部４ａ、４ｂのシャフト５ａ、５ｂを固定金枠２に対して回動可能に設けているためこれらのシャフト５ａ、５ｂの端部を互いに逆回転するようにリンク機構（リンク手段）によって連結することができる。このため本発明ではリンク機構を固定金枠２の一方の短辺側のみに設けることができる。スライディングノズル装置は、プレート交換作業のためスライド金枠３を開閉する機構及びスライド金枠３を駆動装置で駆動する機構を有しているが、本発明ではリンク機構を固定金枠２の一方の短辺側のみに設けることができるためこれらの動きに影響を与えることがない。
In the present invention, since the shafts 5a and 5b of the two slide metal frame holding portions 4a and 4b are provided so as to be rotatable with respect to the fixed metal frame 2, the end portions of these shafts 5a and 5b are rotated in reverse to each other. Can be connected to each other by a link mechanism (link means). Therefore, in the present invention, the link mechanism can be provided only on one short side of the fixed metal frame 2. The sliding nozzle device has a mechanism for opening and closing the slide metal frame 3 for plate replacement work and a mechanism for driving the slide metal frame 3 with a driving device. In the present invention, the link mechanism is connected to one of the fixed metal frames 2. Since it can be provided only on the short side, these movements are not affected.
そして、本発明では第１リンク部７ａの連結部７１ａと第２リンク部７ｂの連結部７１ｂとをリンクバー１０がそれぞれのシャフト５ａ、５ｂの中心軸を結ぶ直線と交差するように連結することで、互いのリンク部が逆回転する関係になる。このため、リンク機構の動きを小さくすることができる。なお、この実施例ではリンク部７ａ、７ｂとしてシャフト５ａ、５ｂに円盤を設けたが、円盤以外でも適用するこができ、例えば、棒状物や板状物とすることもできる。
And in this invention, it connects the connection part 71a of the 1st link part 7a, and the connection part 71b of the 2nd link part 7b so that the link bar 10 may cross | intersect the straight line which connects the center axis | shaft of each shaft 5a, 5b. Thus, the mutual link portions are reversely rotated. For this reason, the movement of the link mechanism can be reduced. In this embodiment, a disk is provided on the shafts 5a and 5b as the link portions 7a and 7b. However, the present invention can be applied to other than the disk, for example, a rod-like object or a plate-like object.
さらに、スライド金枠保持部４ａ、４ｂを閉じた際、第１リンク部７１ａ及び第２リンク部７１ｂは、縦断面においてそれぞれのシャフトの中心軸を結ぶ直線の中央を中心とする点対称の位置とすることで１本のリンクバー１０で連結しても第１リンク部７１ａと第２リンク部７１ｂとがほぼ同期して逆回転することができる。このため、シンプルなリンク機構とすることができためメンテナンス性に優れしかも装置をコンパクトにすることができる。また、リンクバー１０の長孔１０ａのネジ１０ｂで第１リンク部７１ａと第２リンク部７１ｂとの連結長さを微調整することで、２つのスライド金枠保持部４ａ、４ｂを閉じた時にずれることなく完全に閉じることができる。
Furthermore, when the slide metal frame holding portions 4a and 4b are closed, the first link portion 71a and the second link portion 71b are point-symmetrical positions about the center of the straight line connecting the central axes of the shafts in the longitudinal section. By doing so, the first link portion 71a and the second link portion 71b can rotate in reverse in a substantially synchronized manner even if they are connected by one link bar 10. For this reason, since it can be set as a simple link mechanism, it is excellent in maintainability and can make a device compact. When the two slide metal frame holding portions 4a and 4b are closed by finely adjusting the connection length between the first link portion 71a and the second link portion 71b with the screw 10b of the long hole 10a of the link bar 10. It can be completely closed without shifting.
この実施例において下側のスライド金枠保持部４ａと上側のスライド金枠保持部４ｂはほぼ同じ重量であり、それぞれシャフト５ａ、５ｂに対して偏心して固定されているため、開く時は下側のスライド金枠保持部４ｂの自重（重力）の作用で下側のスライド金枠保持部４ｂが下向きに回動するため上側のスライド金枠保持部４ｂを開く作業にはほとんど力が掛からない。
逆にスライド金枠保持部４ａ、４ｂを閉じる際には、上側のスライド金枠保持部４ｂが自重（重力）の作用で閉じる方向（下向き）に回動しようとするのでこの作業にもほとんど力が掛からない。
このため、スライド金枠保持部４ａ、４ｂが同じ重量の場合には、スライド金枠保持部４ａ、４ｂは自然に回動することなく任意の位置で止まることになる。一方、スライド金枠保持部４ａ、４ｂを自重によって開きたいあるいは閉じたい場合には、一方のスライド金枠保持部を他方より重くすることで、バランスが崩れて自然に回動させることができる。 In this embodiment, the lower slide metalframe holding part 4a and the upper slide metal frame holding part 4b have substantially the same weight and are fixed eccentrically with respect to the shafts 5a and 5b, respectively. Since the lower slide metal frame holding part 4b rotates downward by the action of its own weight (gravity) of the slide metal frame holding part 4b, almost no force is applied to the operation of opening the upper slide metal frame holding part 4b.
Conversely, when closing the slide metal frame holding portions 4a and 4b, the upper slide metal frame holding portion 4b tries to rotate in the closing direction (downward) due to the action of its own weight (gravity). It does not take.
For this reason, when the slide metal frame holding portions 4a and 4b have the same weight, the slide metal frame holding portions 4a and 4b stop at an arbitrary position without being naturally rotated. On the other hand, when it is desired to open or close the slide metal frame holding portions 4a and 4b by its own weight, the balance can be naturally rotated by making one slide metal frame holding portion heavier than the other.
逆にスライド金枠保持部４ａ、４ｂを閉じる際には、上側のスライド金枠保持部４ｂが自重（重力）の作用で閉じる方向（下向き）に回動しようとするのでこの作業にもほとんど力が掛からない。
このため、スライド金枠保持部４ａ、４ｂが同じ重量の場合には、スライド金枠保持部４ａ、４ｂは自然に回動することなく任意の位置で止まることになる。一方、スライド金枠保持部４ａ、４ｂを自重によって開きたいあるいは閉じたい場合には、一方のスライド金枠保持部を他方より重くすることで、バランスが崩れて自然に回動させることができる。 In this embodiment, the lower slide metal
Conversely, when closing the slide metal
For this reason, when the slide metal
なお、この実施例は、プレート交換時にスライド金枠保持部４ａ、４ｂが上下に位置する横置きタイプのスライディングノズル装置であるが、プレート交換時にスライド金枠保持部４ａ、４ｂが左右に位置する縦置きタイプのスライディングノズル装置であっても本発明は適用可能である。
This embodiment is a horizontal type sliding nozzle device in which the slide metal frame holding portions 4a and 4b are vertically positioned when the plate is replaced. However, the slide metal frame holding portions 4a and 4b are positioned on the left and right when the plate is replaced. The present invention can also be applied to a vertically installed sliding nozzle device.
＜第２の実施例＞
この実施例は、リンク手段として途中に第３リンク部を有するリンクバーを使用した例である。なお、この実施例は固定金枠２の側面に突起物があったため、第１の実施例のリンクバー１０を取り付けることができず、突起物を避けるために第３リンク部を使用した例である。 <Second embodiment>
In this embodiment, a link bar having a third link part in the middle is used as the link means. In this embodiment, there is a protrusion on the side surface of the fixedmetal frame 2, so the link bar 10 of the first embodiment cannot be attached, and the third link portion is used to avoid the protrusion. is there.
この実施例は、リンク手段として途中に第３リンク部を有するリンクバーを使用した例である。なお、この実施例は固定金枠２の側面に突起物があったため、第１の実施例のリンクバー１０を取り付けることができず、突起物を避けるために第３リンク部を使用した例である。 <Second embodiment>
In this embodiment, a link bar having a third link part in the middle is used as the link means. In this embodiment, there is a protrusion on the side surface of the fixed
すなわち、図６に示すように、固定金枠２の短辺側側面の中央部に回動可能に第３リンク部としてとして中間回転部１１を設け、この中間回転部１１に第１リンクバー１１ａと第２リンクバー１１ｂの一端が回転可能に連結されている。第１リンクバー１１ａの他端は第１リンク部７ａに回転可能に連結され、第２リンクバー１１ｂの他端は第２リンク部７ｂに回転可能に連結されている。なお、第１リンクバー１１ａは途中にターンバックル１１ｃを有しており、これにより第１リンクバー１１ａの長さ、ひいては第１リンク部７ａ（ピン７１ａ）と第２リンク部７ｂ（ピン７１ｂ）とを連結するリンク手段の長さが調節可能になっている。
That is, as shown in FIG. 6, an intermediate rotating part 11 is provided as a third link part in the middle part of the short side surface of the fixed metal frame 2 as a third link part, and the first link bar 11 a is provided in the intermediate rotating part 11. And one end of the second link bar 11b are rotatably connected. The other end of the first link bar 11a is rotatably connected to the first link portion 7a, and the other end of the second link bar 11b is rotatably connected to the second link portion 7b. Note that the first link bar 11a has a turnbuckle 11c in the middle thereof, whereby the length of the first link bar 11a, and thus the first link portion 7a (pin 71a) and the second link portion 7b (pin 71b). The length of the link means for connecting the two can be adjusted.
図６は、スライド金枠保持部４ａ、４ｂが開いた状態であり、この状態からスライド金枠保持部４ａ、４ｂを閉じる際、第１リンク部７ａと中間回転部１１は反時計回り方向に回転する。一方、第２リンク部７ｂは時計回り方向に回転する。したがって、スライド金枠保持部４ａを閉じると、スライド金枠保持部４ｂを連動して同時に閉じることができる。スライド金枠保持部４ａ、４ｂを開く場合も同様に第１リンク部７ａと第２リンク部７ｂが逆方向に回転するので、スライド金枠保持部４ａ、４ｂを連動して同時に開くことができる。
FIG. 6 shows a state in which the slide metal frame holding portions 4a and 4b are opened. When the slide metal frame holding portions 4a and 4b are closed from this state, the first link portion 7a and the intermediate rotation portion 11 are rotated in the counterclockwise direction. Rotate. On the other hand, the second link portion 7b rotates in the clockwise direction. Therefore, when the slide metal frame holding part 4a is closed, the slide metal frame holding part 4b can be simultaneously closed in conjunction with it. Similarly, when the slide metal frame holding portions 4a and 4b are opened, the first link portion 7a and the second link portion 7b rotate in opposite directions, so that the slide metal frame holding portions 4a and 4b can be simultaneously opened in conjunction with each other. .
