COREX process, known as an advanced technology of metallurgical industry presently, can use iron ore and non-coking coal to produce high quality hot metal. COREX工艺是当代冶金工业的炼铁前沿技术,可以使用铁矿和非焦煤生产出优质铁水。
This article deals with the kinetics of thermal decomposition process of non-coking coal with modified coal tar pitch used in a steel company. 本文对国内某钢铁公司焦化厂所用的非焦煤配改质沥青的分解过程进行了动力学研究。
The author proposed that high volatile non-coking coal is used in vertical retort and to meet index of two processes, such as: heat steady property of cake coal and falling strength after carbonization of it. 作者结合自己的试验研究成果和经验,提出高挥发份非炼焦煤用于直立炉须满足的两个工艺指标,即块煤热稳定性和块煤干馏后的落下强度。
At present, the COREX process is the only technology existing on an industrial scale which directly produces hot metal from ore and non-coking coal as reductant; COREX流程是目前世界上以非炼焦煤为主要还原剂,能大规模生产铁水的成熟工艺;
COREX ironmaking means that conventional ironmaking system with blast furnace, coke oven and sintering circuit is replaced by melting reduction ironmaking with non-coking coal and oxygen. COREX是用非炼焦煤与氧气的熔融还原炼铁法,取代传统的高炉、焦炉、烧结组成的炼铁系统。
Based on rich resources of high volatile non-coking coal in China, this paper proposed the idea about that which non-coking coal is used to manufacture city gas in vertical retort of gas plant. 本文根据我国拥有丰富高挥发份非炼焦煤资源特点,提出了煤气厂直立式炭化炉应积极使用非炼焦煤制取城市煤气的设想。
COREX process uses non-coking coal as the main fuel. The structure of energy sources is improved thoroughly. The advantage of COREX process is faded in. COREX流程使用非焦煤资源作为主体燃料,从根本上改善了炼铁工业的能源结构,其优势日渐显著。
After taking into account the conditions of the domestic iron resources, the development of iron and steel industry, and the abundance of domestic non-coking coal resources, the coal-gasification shaft furnace direct reduction becomes the main direction of developing DRI production in China. 综合考虑国内炼铁资源条件及钢铁产业发展现状,发挥国内丰富的非焦煤资源优势,煤制气-气基竖炉直接还原是我国海绵铁生产的主要发展方向。
