Description

Steel flow initiator/ drainage agent is a kind of ladle slid nozzle filler which is successfully developed by our company in recent years, results show that ladle castables success rate of automatic start casting can reach above *5 percent. There is no metallic inclusion in ingot surface, is a kind of ideal ladle slide nozzle filler.
Steel flow initiator contains metal mixture whose weight is heavier and melting point is lower than molten steel. Before pouring we put it into upper nozzle, using it to burning and causing the molten steel within the upper nozzle will not be solidified, to achieve the purpose of automatic start casting and avoid the problem of ingot inclusions.
