One brings out, it is achieved quick-replaceable and flow control.
2) Quick change upper nozzle and quick-change collector nozzle with the use of, according to different steel grades, select different bores to coordinate and make
With.
3) when changing quick-change collector nozzle, new quick-change collector nozzle is placed on the side of elongated track, uses hydraulic cylinder to push away
New quick-change collector nozzle is advanced by bar, is released by the oldest quick-change collector nozzle, it is achieved the online replacing of quick-change collector nozzle.
4) stopper tundish and the pouch-type of fast sprue-replacing tundish are now used in unification, and the most same tundish steel involucrum is the most permissible
Use stopper tundish, it is possible to use fast sprue-replacing tundish, bag resource in saving, it is simple to beam house manages；Meanwhile, adopt
Flow control cast is carried out with stopper and fast sprue-replacing Composite Double safe manner, when occurring that the disconnected rod of stopper, stopper are covered when not waiting indefinitely accident,
Quick-replaceable sewage outlet can be passed through, use metering nozzle to draw the mode of steel, can effectively reduce accident rate, extend tundish
Wrap service life.
The method have the advantages that
It is high that continuous casting production safe flow control technology possesses safety coefficient, it is easy to the advantage of flow control, makees when stopper fracture loses flow control
Used time, it is possible to use quick-change collector nozzle flow control, simultaneously less because of quick-change collector nozzle aperture, it is easy to stifled stream, it is possible to reduce middle Bao Sheng
The generation of product accident.

Detailed description of the invention
Below in conjunction with the accompanying drawing of the present invention, technical scheme is clearly and completely described.
Continuous casting production safe flow control device, in the middle of stopper 1, middle water-coating port split quick-changing type structure and fast sprue-replacing
Bag；Described middle water-coating port split quick-changing type structure is by saving joint B22, Quick change upper nozzle 3 on A21, aluminum zirconium carbon on aluminum zirconium carbon, changing soon
The mouth of a river 7 is constituted；Fast sprue-replacing tundish is made up of installing plate 4, upper guide plate 51, bottom guide 52, gas spring 6；Stopper 1 is positioned at aluminum
Save above A21 on zirconium carbon；Save joint B22, Quick change upper nozzle 3, quick-change collector nozzle 7 on A21, aluminum zirconium carbon on aluminum zirconium carbon sequentially coaxially to fill
Fit over together, form center flow channels；Upper guide plate 51, bottom guide 52 and gas spring 6 form an elongated track, quick-change collector nozzle
7 are arranged on elongated track, are connected with Quick change upper nozzle 3.
Save on described stopper 1, aluminum zirconium carbon on A2, aluminum zirconium carbon and save B21, Quick change upper nozzle 3 is tubular.
The method of continuous casting production safe flow control device flow control, including the following method of operation:
