Experimental Research of Composition Control of CaO-SiO2-Al2O3-MgO In- clusion by Using Low Basic Top Slag for Tire Cord Steel

Wanjun Wang

Abstract

The effect of top slag composition on CaO-Al2O3-SiO2 inclusion composition was studied by controlling the condition of deoxidization and composition of top slag in experimental furnace in which the tire cord steel was melt. The content of A12O3 in inclusion increased with that in top slag increasing while the basicity of top slag was fixed. Plastic inclusion presented while the content of A12O3 in top slag was below 8%. It is concluded that the composition of the inclusion can be controlled within the plastic area by controlling the condition of deoxidization and the composition of top slag.
