以转炉炼钢过程为研究对象,建立了分析模型,对转炉炼钢能量转换过程进行了分析。结果表明,转炉吨钢损失为439.54MJ,其中外部损失占总损失的比例为96.63%,转炉渣排放引起的损失比例为69.29%。减少转炉炼钢过程损失重点在于转炉渣量的控制和转炉渣余热的回收与利用。 Taking converter steelmaking process as the research object, an analytical model was established to analyze the energy conversion process of converter steelmaking. The results show that the loss per tonne of converter steel is 439.54MJ, of which the loss ratio of external and total losses is 96.63% and the loss ratio caused by converter slag discharge is 69.29%. Reduce the converter steelmaking process, the focus of loss is the control of converter slag and waste heat recovery and utilization of converter slag.
