摘　　要：2 10t转炉顶底复吹技术的研究和应用 ,为包钢CSP生产线生产低碳钢种提供了保证。复吹转炉保持良好的冶金效果 ,碳氧反应接近平衡 ,冶炼低碳钢时避免了钢水的过氧化 ;较顶吹有良好的脱磷、脱硫能力 ,提高了终点残锰量。Development and application of the technology of 210 ton combined blown converter provide a sure condition for CSP to produce low carbon steel products; the metallurgical effects can be guaranteed by combined blown converter, the C-O2 reaction approaches to a balance and over oxidation in the hot metal disappears and as a result, the original dephosphorization level and the desulphurization level of the combined blown converter as well as Mn residual content at the end point still remain unchanged.
