Abstract

In order to reduce dust formation and entrainment during steel production, it is necessary to know its formation mechanism. Existing ideas are based on combined effects or on model idealized studies, whereas there are no direct studies of such fundamental processes as evaporation of melt of the Fe–C system at steel smelting process temperatures. In this work, iron vapor pressure and melt evaporation rate from Fe–C melts are measured at temperatures up to 2200°C. An equation is obtained for the temperature dependence of these parameters. The task of suppressing dust formation involves a reduction in reaction zone temperature during blowing a bath with oxygen with retention of a sufficiently high carbon oxidation rate.
