description The invention discloses a molten steel cleaning agent which is used for removing suspended non-metallic inclusions in molten steel in a molten state and gas dissolved in a metal solution, improving the quality of the molten steel and reducing the slag hole and pore rate of a casting product. The molten steel cleaning agent comprises 70%-80% of cement and 30%-20% of fluorite powder. By adding the molten steel cleaning agent into a furnace, the quality of molten steel can be improved, the slag hole and pore rate of casting products is reduced, and the percent of pass of the casting finished products is greatly increased. Different from the situation that similar products are limited to slagging in a ladle outside a furnace, extra temperature drop is caused by standing of molten steel, and heat is lost, the in-furnace slagging characteristic of the molten steel cleaning agent can reduce furnace wall slag adhesion, lower the furnace wall thickness, improve the induction heating efficiencyand reduce the energy con
