北京冶金设备研究院首创的ＰＦ法竖炉直接还原工艺1999年4月在山西朔州三元碳素公司进行了半工业试验,为我国竖炉煤基直接还原铁生产开辟了一条新路。钢铁生产传统流程是由焦化、烧结、高炉、炼钢、模铸和轧钢等工序组成,流程长、投资大、能耗高、环境污染严重,且焦煤资源有限 Beijing Institute of Metallurgical Equipment pioneered the PF method shaft furnace direct reduction process April 1999 in Shuozhou, Shanxi ternary Carbon Company conducted a semi-industrial test for China’s shaft furnace direct reduction of coal-based coal production has opened up a new road. The traditional steel production process is composed of coking, sintering, blast furnace, steel making, die-casting and steel rolling processes. The process is long, investment is large, energy consumption is high, environmental pollution is serious, and coking coal resources are limited
