Tundish Coating Powder의 鹽基性化에 關한 硏究

The properties of basic tundish coating powder were investigated, comparing with acidic tundish coating powder, especially in the corrosion resistance to the molten steel and the influence on non-metallic inclusion. The results show that the basic coating powder is superior to the acidic coating powder in corrosion resistance. It is appeared that the basic coating powder lining has less influence on the formation of non-metallic inclusion. These results will be promissing to reduce the coating thickness in tundish lining operation.
