Device for purifying molten steel inclusions by argon blowing in tundish

Abstract

The utility model discloses a device of argon blowing purification molten steel inclusions of tundish, is used for tundish, and this device includes weir plate, gas -permeable brick and vent pipe, and weir plate and gas -permeable brick all are arranged on the permanent layer of tundish and are fixed with working layer, and gas -permeable brick is located at the bottom of weir plate, and the flow guide hole is left between weir plate and gas -permeable brick, one end of vent pipe is connected with gas source, and the other end is communicated with gas -permeable brick, and gas -permeable brick is supplied with gas to make gas -permeable brick produce the air curtain retaining wall of flow guide hole. Gas -permeable brick has the ability of stable and reliable delivery of a large number of small argon gas bubbles, and the weir plate flow guide makes the molten steel concentratedly flow out, and a large number of small argon gas bubbles can significantly reduce the inclusions in molten steel through the molten steel of concentrated flow guide, and meanwhile, the argon blowing brick is assembled with weir plate, and the whole is good in integrity and not easy to loosen, and the use safety is high.
