为生产低碳不锈钢减少低碳区铬的氧化损失,在实验室的模型炉中,试验研究了在钢水成份、温度及其它条件都基本相同的情况下,以水冷顶吹氧枪吹纯氧+底气搅拌、吹(O_2+N_2)+底气搅拌和纯氧项吹无底气搅拌三种不同工艺,吹炼至终点[C]=0.03%时Cr的相对氧化率。试验得出,脱碳速度、氧的利用率和Cr的氧化率,不同吹炼条件下的差别很大。 For the production of low-carbon stainless steel to reduce the low-carbon chromium oxidation loss in the laboratory model furnace, the experimental study of molten steel composition, temperature and other conditions are basically the same circumstances, the water-cooled top-blowing oxygen gun blowing pure oxygen + The relative oxidation rate of Cr at the end of [C] = 0.03% during the mixing of bottom gas, blowing (O_2 + N_2) + bottom gas mixing and pure oxygen bubbling without bottom gas mixing. The experiment shows that the rate of decarburization, the utilization of oxygen and the oxidation rate of Cr are very different under different blowing conditions.
