Abstract
The utility model discloses a device for fast replacing casting sizing water gate of tundish for continuous casting. The lower part of a sizing water gate 1 of the device is sheathed with an immersed water gate 4. Through the device, the sizing water gate 1 can be fast replaced without being intermittent under protection casting operating conditions. The production efficiency is enhanced, the accident rate is lowered, and the stability for pulling steel and the quality of a casting blank are enhanced.
Description
The utility model relates to a kind of metering nozzle that is used under continuous casting tundish molten steel beam pouring condition quick replacement device that continues to flow.
Existing billet caster generally adopts metering nozzle to open wide cast; bloom; rectangular bloom and other billet caster are generally used " stopper control+middle water containing opening+submersed nozzle " protection cast; its common deficiency is after certain hour is produced in cast; because molten steel is to metering nozzle; stopper; washing away and etch of middle water containing opening; it is excessive the steel flow flux to occur; pulling rate is too fast; problems such as stopper control loss control; thereby generation slab quality; accidents such as production and equipment; owing to open wide the metering nozzle of cast usefulness and the stopper of protection cast usefulness; middle water containing opening can't in use according to circumstances be changed; make each continuous casting water the length in time production cycle; directly be subjected to metering nozzle; stopper; or the restriction in middle water containing opening life-span, have a strong impact on the raising of production efficiency.For addressing the above problem, people have designed the tundish metering nozzle quick replacement device that continues to flow, it comprises metering nozzle, sliding way, glide path, jockey, hydraulic means, when metering nozzle corrodes when serious, the metering nozzle that can continue to flow is changed, and has well improved production efficiency.But there is a very big defective in the quick replacement device that continues to flow that uses at present, can not be applied to the protection cast, and this device was unavailable during the protection cast was produced.
The purpose of this utility model is to provide a kind of quick replacement device of realizing continuous casting tundish molten steel beam protection pouring operation.
The utility model is achieved in that a kind of continuous casting basket pouring metering nozzle quick replacement device, comprises metering nozzle, sliding way, glide path, jockey, hydraulic means, and the metering nozzle bottom is connected with submersed nozzle.
Described submersed nozzle is fixed on the metering nozzle by controlling device, controls device one end and is enclosed within on the submersed nozzle, and the other end hangs counterweight, and the middle part is suspended on the tundish involucrum by hook.
As further improvement of the utility model, be provided with sealing gasket between described submersed nozzle and the metering nozzle.
Advantage of the present utility model is: after the metering nozzle bottom increased submersed nozzle, continuous casting basket pouring metering nozzle quick replacement device can realize protecting pouring operation.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model cutaway view.
Fig. 2 changes schematic diagram for the utility model mouth of a river.
As shown in Figure 1, submersed nozzle 4 is socketed in metering nozzle 1 bottom, fill special-purpose sealing gasket 5 between the two, prevent that air is inhaled in the casting process, submersed nozzle 4 by control controlling of device 6 firmly be installed in metering nozzle 1 below, controlling device 6 one ends is toroidal, be socketed on the submersed nozzle 4, the other end hangs counterweight 7, and the middle part is suspended on the tundish involucrum by linking up with 8, can make and controls device and submersed nozzle is accurately located by adjusting counterweight 7 and hanging position.
Behind the continuous casting appropriate time; metering nozzle 1 is owing to being subjected to the etch of molten steel and washing away; it is big that inner cavity size becomes; no longer be fit to continue the requirement that cast is produced; expire service life; can move and control device 6 submersed nozzle 4 and metering nozzle 1 are thrown off; pass through the driving effect of hydraulic cylinder again; shift a new metering nozzle 1 ' onto pouring position; simultaneously old metering nozzle 1 is pushed away pouring position; as shown in Figure 2; new metering nozzle 1 ' replaces old metering nozzle 1 work; realize the quick replacing of metering nozzle 1; 4 life-spans of submersed nozzle are changed when expiring routinely; the quick replacing of metering nozzle 1 can be carried out infinitely repeatedly, thereby realizes (stopper and supporting with it middle water containing opening cost an arm and a leg) of non-stopper control; replaceable metering nozzle; high efficiency; low accident rate; high slab quality; high strand recovery rate; the continuous casting protection cast of the low cost of anti-the material is produced.The quick replacing of metering nozzle 1 and the replacing of submersed nozzle 4, labour intensity is little, and is simple to operation, can not bring any harmful effect to molten steel beam and slab quality, also can not bring any harm to environment.
This utility model can be used for the protection cast of square billet, rectangular bloom, large rectangle base, slab and the shaped blank continuous casting of all size and produces.
