[0002] Drainage sand is a refractory material used for the nozzle of a tundish. Before the tundish receives the molten steel from the converter, it is necessary to put drainage sand into the nozzle of the tundish. The drainage sand can prevent the molten steel from solidifying at the nozzle of the tundish and affecting the pouring of the tundish; the drainage sand needs to be accurately put into the nozzle to play a role.
[0003] At present, there are two methods for putting drainage sand into the tundish nozzle: manual feeding and feeding with a sand feeder. Both manual feeding and the sand feeder have the problem of inaccurate feeding position and cannot accurately put the drainage sand into the nozzle, which will cause waste of drainage sand, increase production costs, and in order to accurately deliver, the diameter of the feeding pipe is small and prone to blockage. The existing device does not have the function of dredging the feeding pipe, resulting in the situation that the drainage sand is blocked at the nozzle of the feeding pipe during the feeding process.
