在钢包内用矽铁及锰铁脱氧的方法,包括浇铸和在钢锭模内用矽铁及莹石粉精炼钢液。为提高金属的表面质量、提高合格率、降低脱氧剂及钢锭模的消耗,在浇注过程中用合成渣对钢液进行精炼,合成渣为:矽铁、转炉钢渣和氟化,渣比为:1:(4.5—8):(1—1.5)。用量为每吨 Methods of deoxidation with ferrosilicon and ferromanganese in ladles, including casting and refining of molten steel with ferrosilicon and flint powder in a steel ingot mold. In order to improve the surface quality of metal, improve the pass rate and reduce the consumption of deoxidizer and ingot mold, the molten steel is refined with synthetic slag during the pouring process. The synthetic slag is: ferrosilicon, converter steel slag and fluorinated slag ratio: 1: (4.5-8) :( 1-1.5). The dosage is per ton
