Abstract
PURPOSE:To perform slag expulsion efficiently by sucking and expelling the slag produced by desiliconization of molten iron from bath surface under specific conditions. CONSTITUTION:The slag produced on the molten iron surface in a treating vessel by desiliconization treatment of molten iron is sucked and expelled from the bath surface by using a suction port of a suction head of about 50-300mm.phi, disposing the same at height 20-70mm. above the bath surface and using 20-500Nm<2>/min wind flow rates. Thereby, the desiliconization slag of about 90-100% may be expelled efficiently from the molten iron bath surface. The viscosity of desiliconization slag is approximately less than 1 poise at 1,350 deg.C.
