由于高炉焦炭所需高质量炼焦煤的匮乏,迫使设备提供商和钢铁生产厂寻求只需要少量焦炭的炼铁设备。COREX就是满足这种条件的一种工艺,该工艺使用非焦煤做燃料、球团矿做含铁原料。该工艺由于不需要建设焦炉,比高炉工艺对环境更加友好。印度京达尔公司投产了两套COREX炼铁设备,每套设备的年产量均为80万t。多年来,公司确定了高效的操作参数、对原料 The lack of high quality coking coal for blast furnace coke has forced equipment providers and steelmakers to seek out ironmaking equipment that requires only a small amount of coke. COREX is a process that meets this condition, using non-coking coal as the fuel and pellets as the iron-containing feedstock. Due to the fact that the process does not require the construction of a coke oven, the process is more environmentally friendly than the blast furnace process. The company has commissioned two COREX ironmaking plants in India, each with an annual production of 800,000 t. Over the years, the company has identified efficient operating parameters for raw materials
