本文总结了现场实测所得数据,计算了熔炼过程的热平衡。经过技术分析指出,该厂摆脱困境的近期措施应以加强原料管理和提高风口操作水平为主,适当改进炉子结构。从长远看,要根本改变工艺与原料不适应状况,采用熔池熔炼代替现有的密闭鼓风炉是一个合理的方案。 This article summarizes the field measured data, calculated the heat balance of the melting process. After the technical analysis pointed out that the plant to get rid of the plight of the recent measures should be to strengthen the management of raw materials and improve the operation of tuyere-based, proper improvement of the furnace structure. In the long run, it is necessary to fundamentally change the incompatibility between process and raw materials. It is a reasonable solution to adopt molten pool melting instead of the existing closed blast furnace.
