2提高连铸坯洁净度技术连铸过程中生产洁净钢,一方面是去除液体钢中氧化物夹杂,进一步净化进入结晶器的钢水,另一方面是防止钢水的再污染。对于液体钢中夹杂物去除主要决定于夹杂物形成、夹杂物传输到钢——渣界面和渣相吸附夹杂物。对于防止连铸过程钢水再污染,主要决定于:(1)
2 to improve the cleanliness of continuous casting billet technology Continuous production of clean steel, on the one hand is to remove oxide inclusions in liquid steel to further purify the molten steel into the mold, on the other hand is to prevent re-contamination of molten steel. The removal of inclusions in liquid steel mainly depends on the formation of inclusions, inclusions transfer to the steel-slag interface and the slag phase adsorption inclusions. For the prevention of recasting of molten steel in the continuous casting process, it mainly depends on: (1)
