大型转炉炼钢过程的冶金反应

Metallurgical Reactions in Steelmaking Process for 300 t BOF

研究了宝钢 [宝山钢铁 (集团 )公司 ]30 0 t转炉炼钢过程中熔池金属成分、炉渣成分、温度的变化以及熔池脱碳、脱磷、脱硫的情况 ;检测了炉渣的流动温度和岩相结构 ,分析了渣 -钢之间化学反应的平衡状况和氧射流对熔池的作用。研究结果表明

The variation of the composition of melt, slag and the temperature, the reaction of decabonrization, dephosphorization, desulphurizaton in the bath were quantitatively studied. The slag temperature and morphology were measured and observed. The equilibrium between the slag and melt and the reaction of oxygen jet with the bath were analyzed. The steelmaking process on Baosteel ′s converter is reasonable on the whole.
