产品概述：
精炼渣是指将铝灰与石灰石等原料按一定比例和粒度混合后，在高温加热的情况下使原料烧结在一起，再破碎成颗粒后的产品。主要用作炼钢脱硫脱氧剂，具有成渣迅速、埋弧、造渣、减少钢中气体、吸收钢液夹杂等作用。

Product Overview:
Refining slag refers to the product obtained by mixing aluminum ash with limestone and other raw materials according to a certain proportion and particle size, sintering the raw materials together under the condition of high temperature heating, and crushing the raw materials into particle size.  It is mainly used as steel-making desulfurization deoxidizer, and has the functions of rapid slag formation, submerged arc, slagging, reduction of gas in steel, absorption of inclusions in molten steel, etc.
