高炉大型化是钢铁行业的总趋势,是降低成本和环境污染的必然途径,同时也是国家进行钢铁行业宏观调控的重要举措。高炉的大型化对焦炭质量的稳定提高提出了新的要求,同时也成为企业炼焦工作者需要解决和追求的目标。一、基于高炉大型化的焦炭质量管理的背景随着钢铁工业的发展,高炉已由过去的几百立方米发展到现今的4000立方米以上的大容积高炉,由于高炉容积日趋增大和风口喷煤量的逐渐增多,焦炭在高炉中的停留时间随之增长,焦炭在高炉中
Large-scale blast furnace is the general trend of the steel industry, is the inevitable way to reduce costs and environmental pollution, but also the country’s macro-control of the steel industry an important measure. The large-scale blast furnace put forward new requirements for the steady improvement of the quality of coke, and it has also become the goal that enterprise coking workers need to solve and pursue. I. Background of Coke Quality Management Based on Large-scale Blast Furnace With the development of the steel industry, the blast furnace has been developed from the past several hundred cubic meters to the present large-volume blast furnace with a capacity of over 4,000 cubic meters. Due to the increasing volume of the blast furnace and the pulverized coal injection Gradual increase in the amount of coke in the blast furnace residence time increases, coke in the blast furnace
