Description
The utility model relates to a kind of conticaster tundish quick molten steel flow of aperture, the mouth of a river, accurate control injection crystallizer and device of stream burst external form regulated in the continuous pouring process, belongs to metallurgical casting equipment technical field.
At present, the control mode of casting machine regulation and control tundish injection crystallizer molten steel flow mainly contains stopper control stream, slide gate nozzle control stream and metering nozzle cooperation tundish molten steel liquid level (static pressure) control stream.Their common shortcomings are operational sequence and preparation complexity; labor strength is big; the mouth of a river is shorter relatively service life; the time is watered by the company that has limited tundish; steel flow thigh profile is not whole; as not taking safeguard measure; be easy to the defective that causes strand to scab because of the stream that looses, in addition, crystallizer steel bonding suitable for reading also causes the extension steel cutout accident of casting process easily; and most importantly along with the prolongation of service time; control stream unit in the mouth of a river is by molten steel scouring or deteriorate, and control stream precise decreasing forces the casting machine pulling rate to improve; cause the strand inherent quality to descend, and bleed-out and excessive steel accident take place easily.Chinese patent discloses a kind of rotary mouth of a river that is used for controlling the metal casting flow of molten metal for No. 89201157.2, mainly by swingle, the mouth of a river and open respectively in swingle and the molten metal hand-hole on the following mouth of a river and form down, the shortcoming of having eliminated the chock plug displacement of stopper control system and having come off, can accurately control beam, but owing to be that spheroid cooperates between the mouth of a river, the swingle of spheroid needs hydrostatic pressing, processed complex, the refractory material consumption is many, cost is high, and changes the mouth of a river and need quit work 1-2 days.
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of by aperture, the rapid conversion mouth of a river, and the flow that makes molten steel pass through the mouth of a river sets value mutually attached device with cast all the time.
The technical solution of the utility model is achieved in that in the lower end of middle water containing opening brick cup settles an orifice plate, metering nozzle is installed in the brick cup and with the orifice plate butt joint and cooperates, the control fluid element support by supporting mechanism and with the orifice plate plane contact, and can be along the translation of link rod pushing direction, one end of link rod props up the control fluid element, and the other end is then hinged with the crank of band handle.When needs regulation and control molten steel flow, available displacement elements (control fluid element) translation with the mutually attached aperture of setting value is replaced, and crank can be transformed into pulling force to controlling the thrust of fluid element by link rod, promotes the control fluid element and moves into place.
The utility model is simple in structure, easy to use, be convenient to integral installation and dismounting, can change the control fluid element rapidly, flow control effect is good, can prevent to hang the generation of accidents such as steel, bleed-out effectively, improve tundish greatly and water steel time and caster work rate continuously, reduce the loss of refractory consumption rate and tundish filling remaining liquid steel, for a sequence casting steel mill that produces 2000000 tons of scales of steel per year, a year benefit can reach ten thousand yuan of 800-1000.Simultaneously, the utility model can also be designed to one with control fluid element and crystallizer submersed nozzle, play more faster than stopper control streaming system, than the result of use of the easier economy of slide gate nozzle system.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Accompanying drawing 2 is control fluid element supporting mechanism schematic diagrames of the utility model embodiment.
Accompanying drawing 3 is control fluid element supporting mechanism side views of the utility model embodiment.
With reference to accompanying drawing, settling a material in the lower end of middle water containing opening brick cup 1 is graphite or aluminium oxide mix and have better lubricity with graphite orifice plate 10, metering nozzle 2 is installed in the brick cup 1 and with orifice plate 10 butt joints and cooperates, control fluid element 9 support by supporting mechanism and with orifice plate 10 plane contact, and can be along link rod 7 pushing direction translations, one end of yoke plate 7 props up control fluid element 9, the other end and then is hinged with the crank 6 that band is removed 5, and 4 is middle cylinder-packing.For changing the control fluid element rapidly, this device is provided with the control fluid element 8 of a backup, control fluid element 8 support by same supporting mechanism with control fluid element 9 and with orifice plate 10 plane contact, control fluid element 8 and can be along link rod 7 pushing direction translations between control fluid element 9 and link rod 7.To the supporting mechanism of control fluid element 8,9 and orifice plate 10 is by bolt 16 outer gimbal support 11 to be fastened at the bottom of the tundish on the steel plate 3, interior hanger 13 carrying control fluid elements 8, control fluid element 9 and support spring 12, and be hinged on the outer gimbal support 11 by bearing pin 14, binding 15 is outer gimbal support 11 times.The fastening force of bolt 16 can be even by spring, is applied to reposefully on control fluid element 8,9 and the orifice plate 10, and control fluid element 8,9 is supported on the wear-resisting orifice plate 10 flexibly.The interior hanger 13 that hangs is a fulcrum with bearing pin 14, and part 8,9 is supported on the wear-resisting orifice plate 10 flexibly.It is fulcrum that the interior hanger 13 that hangs takes out 14 with pin, spring 12 compresses by name a person for a particular job control fluid element and orifice plate 10 from an end, dividing plate between the hanger had both played and has prevented invar water and cause spring annealing by the high temperature that the control fluid element produces, play the lateral shift effect in the restriction displacement control fluid element process again, guaranteed sleeve mechanism accuracy and reliability at work.Interior hanger 13 is mounted for the guide rail form, is used to control the guiding of fluid element, location and slip.When needs regulation and control molten steel flow or when changing control fluid element 9, availablely replace with the backup displacement elements 8 quick translations in the mutually attached aperture of setting value.Hand is removed and is provided with 5 for manual operation, also can adopt hydraulic pressure and pneumatic linear actuator to promote, crank 6 can be delivered in manpower to back up on the control fluid element 8 and promote control fluid element 9 by link rod 7 and arrive orifice plate 10 times, docks with the hole on the orifice plate 10, realizes the regulation and control of molten steel flow or changes the control fluid element.
