本考案は走間式切断装置の刃物冷却装置に関す
るものである。[Detailed Description of the Invention] The present invention relates to a blade cooling device for a running cutting device.
走間式切断装置は連続鋳造ラインの途中に設け
られ、搬送されてくる連続した鋼片（スラブ）の
搬送速度に合わせて移動しつつ鋼片を切断する。
従つて鋼片を停止させることなく切断できる。 The running cutting device is installed in the middle of a continuous casting line, and cuts the continuous steel slabs while moving in accordance with the conveyance speed of the continuously conveyed slabs.
Therefore, the steel piece can be cut without stopping.
この切断装置は上下の刃物を有し、上刃物を昇
降自在に設けた形式のものや、下刃物を昇降自在
に設けたもの、あるいは、上下の刃物を昇降自在
に設けた形式のものがある。本実施例では、上刃
物を昇降自在に設け、下刃物を固定させた形式の
走間式切断装置に刃物冷却装置を設けた場合を説
明する。 This cutting device has upper and lower blades, and there are types in which the upper blade can be moved up and down, those in which the lower blade can be moved up and down, and those in which the upper and lower blades can be moved up and down. . In this embodiment, a case will be described in which a blade cooling device is provided in a running type cutting device in which the upper blade is movable up and down and the lower blade is fixed.
ところで、連続鋳造鋼片の温度は約900〜1000
度の高温であるため下降しつつ切断を行なう上刃
物は高温となり、刃物の切れ味が悪くなつてしま
う。 By the way, the temperature of continuously cast steel billet is about 900-1000
Because the temperature is so high, the upper blade that cuts while descending becomes hot, and the blade loses its sharpness.
そこで、上刃物が取付けられた上側刃物台に冷
却水の循環水路を設け、冷却水を循環させ、上刃
物の冷却を行なう構造が提案されている。 Therefore, a structure has been proposed in which a cooling water circulation channel is provided in the upper tool rest to which the upper cutter is attached, and the cooling water is circulated to cool the upper cutter.
しかし、このような構造を採用しても上刃物の
冷却は刃物台を介しての間接冷却であり上刃物を
充分に冷却することができなかつた。 However, even if such a structure is adopted, the upper cutter is cooled indirectly through the tool post, and the upper cutter cannot be cooled sufficiently.
上刃物を充分に冷却するためには直接的に冷却
水を噴き付ければよいが、上刃物は高温の鋼片の
上側にあるため噴き付けられた水が高温の鋼片の
上に降りかかつてしまう。 In order to sufficiently cool the upper cutter, it is possible to spray cooling water directly onto it, but since the upper cutter is located above the hot steel piece, there is a possibility that the sprayed water may fall on the hot steel piece. Put it away.
高温の鋼片に水が掛かると鋼片の温度が下がる
だけでなく、いわゆる焼入れ状態が生じたり、ク
ラツクが生じることになり、不良品が発生してし
まう等の不都合を生じる。 When a hot steel piece is exposed to water, the temperature of the steel piece not only decreases, but also causes a so-called quenching state or cracks, resulting in inconveniences such as the production of defective products.
本考案は以上のような事情に鑑みなされたもの
で、冷却水を上刃物に直接散水でき、しかも冷却
水が鋼片に掛からないように構成した走間式切断
装置の刃物冷却装置を提供することを目的として
いる。 The present invention was developed in view of the above-mentioned circumstances, and provides a blade cooling device for a running type cutting device that is configured to spray cooling water directly onto the upper blade and prevent the cooling water from splashing onto the steel piece. The purpose is to
本考案においては上記の目的を達成するために
上刃物部に冷却水の散水装置を設け、走間式切断
装置に隣接させて集水といを鋼片の搬送方向と直
角な水平方向に移動自在に設け、この集水といを
上昇位置にある上刃物と鋼片との間に出し入れ可
能に設けた構造を採用した。 In order to achieve the above-mentioned purpose, in this invention, a cooling water sprinkling device is installed in the upper cutter section, and the water collection gutter is placed adjacent to the running cutting device and can be moved in the horizontal direction perpendicular to the conveying direction of the billet. A structure was adopted in which this water collection gutter was installed between the upper cutter and the steel piece in the raised position so that it could be taken in and out.
