由于炼钢用生铁与铸造生铁硅元素含量的不同要求,高炉炼铁的生产工艺有所不同,通过炼钢生铁与铸造生铁冶炼生产工艺及煤气回收利用水平的比较,说明了影响铸铁生产高炉工序能耗升高的原因。
Due to the different requirements for the content of silicon in pig iron and foundry pig iron, the production process of blast furnace iron is different. The comparison between the production technology of pig iron and pig iron and the recovery and utilization of pig iron shows that the blast furnace process The reason for the increase in energy consumption.
