目前世界各国炼钢大都采用三步工艺流程。这种炼钢工艺会产生苯、氨等有毒有害气体,且能耗很高。 为了解决这一难题,各国科学家纷纷为寻求无污染炼钢术而煞费苦心。 美国钢铁学会联合能源部的工程师们探索的“一步法”成功地“合三为一”,避免了以煤作主要燃料造成的严重污染。这种“绿色炼钢术”的工艺是,将铁矿石和煤同时放入加热炉并吹入氧气,铁水即从容器中流出,硫和碳化合物等有害气体则在此过程中被去除,最后得到纯钢。眼下他们正在试制耐
At present, most countries in the world use three-stage steelmaking process. This steelmaking process will produce benzene, ammonia and other toxic and harmful gases, and high energy consumption. In order to solve this problem, scientists from all over the world have made painstaking efforts to seek pollution-free steelmaking. The “one-step” approach explored by the engineers of the United Steel Institute’s Department of Energy has succeeded in “combining all three into one,” avoiding the serious pollution caused by using coal as the main fuel. This “green steelmaking” process is that the iron ore and coal are put into the furnace at the same time and the oxygen is blown in. The molten iron flows out of the container and harmful gases such as sulfur and carbon compounds are removed in the process. Finally, Get pure steel. Right now they are trial and error
