1、The Use of Silicon Barium
Silicon barium alloy is widely used in steelmaking, steel casting, foundry industry and other industries. It is an efficient and long-lasting deoxidizer, and has the function of desulfurization and dephosphorization. Silicon barium alloy application: 1. The inoculant is suitable for gray cast iron and ductile iron, and can promote the formation of "A" type graphite to complete the formation of graphite nodules. 2. It can be nucleated in a wide temperature range, with strong spheroidization ability and anti-recession ability, which can effectively prevent the tendency of casting white mouth. 3. When the silicon-barium alloy containing 10%-35% barium is used as a deoxidizer for steelmaking, the utilization rate is high and the desulfurization ability is strong, which is better than the silicon-calcium alloy. 4. After the addition of silicon-barium alloy, the essence and distribution characteristics of non-metallic inclusions in steel can be changed significantly.
