就复合合金对特殊钢中夹杂物的变性机理进行分析讨论,采用复合脱氧剂脱氧时能使容易挥发的钙、镁在钢中的溶解度增加,脱氧剂能使夹杂物形态和组成发生变化,有利于改善钢的性能,同时钙?钡对夹杂的变性能力随钙?钡含量的增加和钢中铝含量和硫含量的降低而增强。为洁净钢的生产工艺提供理论支撑和提高钢的洁净度提供理论依据。
The mechanism of degeneration of inclusions in special steels was analyzed and discussed. The deoxidation of composite deoxidizers could increase the solubility of easily volatilized calcium and magnesium in steel. The deoxidizer can change the shape and composition of inclusions. Conducive to improving the performance of steel, while the calcium barium Inclusion modification with the increase of calcium and barium content and steel content of aluminum and sulfur content increased. Provide theoretical basis for the clean steel production process and improve the cleanliness of steel provide a theoretical basis.
