INTRODUCTION

Silicon barium has high activity and is a long-term and efficient inoculant in the production of cast iron. 1t barium silicon alloy can replace 1.5t ferrosilicon economically. Silicon barium inoculant is suitable for grey cast iron and nodular cast iron. Strong spheroidizing ability and anti-aging ability, effectively preventing the tendency of casting white mouth; The deoxidation effect is relatively complete, superior to other deoxidizing alloying agents, and the addition amount is 35% - 50% of 75 # ferrosilicon; When silicon barium alloy is used for deoxidation in steelmaking, it has high utilization rate and strong desulfurization ability, superior to silicon calcium alloy.
