多年来我厂炼钢基本工艺的主要特点是“三期”操作:即熔化期,氧化期,和还原期(以下简称老工艺)。氧化期采用矿石加氧气氧化,还原期采用传统的扩散脱氧方法。因此冶炼时间长,能源消耗高,生产效率低,严重影响了经济技术指标的提高。为生产出物美价廉的产品,加快四化建设,改革炼钢基本工艺势在必行。随着炼钢生产实践的发展,电炉炼钢理论的研究,新技术新设备的采用,人们对电炉炼钢基本规律的认识,也在不断深入,因此对电炉炼钢基本工艺改革条件已经成熟。今年初抚顺钢厂与北京钢铁学院合作,对老工艺进行剖析,围绕改革老工艺开展了试
Over the years I plant the basic characteristics of the basic process of steel is “three” operation: the melting period, the oxidation period, and the reduction period (hereinafter referred to as the old process). Oxidation of ore plus oxygen oxidation, the reduction of the traditional method of diffusion deoxidation. Therefore, smelting a long time, high energy consumption, low productivity, seriously affected the economic and technical indicators. In order to produce inexpensive products, speeding up the building of the four modernizations and reforming the basic process of steel making are imperative. With the development of steelmaking practice, the study of EAF steelmaking theory, the adoption of new technology and new equipment, people’s understanding of the basic rules of EAF steelmaking are also continuing to deepen, so the conditions for the reform of EAF steelmaking technology have matured. Earlier this year, Fushun Steel and Beijing Institute of Iron and Steel cooperation in the analysis of the old process, the process around the reform of the old trial
