美国钢铁学会与墨西哥Hylsa公司的HYL分公司合作,目前正在开发旨在取消炼焦炉—高炉—碱性氧气转炉工艺的一步炼钢法。 一步炼钢工艺的主要原理是用煤和氧气直接还原加到铁浴中的经过预热和预还原的铁矿石。铁矿石和煤从熔炼炉上部加到铁水熔池中,而氧气从炉子的底部和顶部吹入。熔炼炉内连续进行脱硫和脱碳处理。当碳含量降至小于1％时,将钢水输入钢包炉中进行精炼,在熔炼炉冶炼期间,反应物产生的热量用来
The American Iron and Steel Institute, in partnership with Hylsa’s HYL division in Mexico, is currently developing a one-step steelmaking process aimed at eliminating the coke oven - blast furnace - alkaline oxygen converter process. The main principle of the one-step steelmaking process is the direct reduction of preheated and prereduced iron ore added to the iron bath with coal and oxygen. Iron ore and coal were added to the molten iron bath from the top of the furnace, while oxygen was blown in from the bottom and top of the furnace. Smelting furnace for continuous desulfurization and decarbonization. When the carbon content is reduced to less than 1%, the molten steel is fed into a ladle furnace for refining. During the smelting of the smelter, the heat generated by the reactants is used
