介绍复合脱氧剂铝锰铁合金试制工艺及脱氧原理。在炼钢中用它代替金属铝进行脱氧试验，不仅可以代替金属铝做炼钢脱氧剂，而且可以提高钢的脱氧率，减少钢中夹杂物，提高钢的纯洁度，并具有显著的经济效益，值得推广应用。 Introduction composite deoxidizer aluminum ferromanganese alloy trial production process and deoxidation principle. It is used instead of metal aluminum in steelmaking for deoxidation test, which not only can replace metal aluminum as steelmaking deoxidizer, but also can improve the deoxidation rate of steel, reduce inclusions in steel, improve the purity of steel, and have significant economic benefits , It is worth promoting application.
