前 言 近代钢铁生产工艺已有了长足的进展;冶炼设备专门化的高负荷操作,喷射氧气快速炼钢,喷射惰性气体加速传质,喷射高表面反应剂提高精炼效率等行之有效的新流程、新方法已投入工业应用。在这个形势下。将以上新技术尽多地,有机地应用于电弧炉冶炼工艺,是一个有意义的课题。 国内电弧炉炼钢工艺目前的主要状况是: 1.炉子仍做为综合性设备进行低负荷操作。表现为在传热方面实行电力曲线制,在传
Preface Modern steel production process has made considerable progress; smelting equipment, specialized high-load operation, rapid oxygen injection steelmaking, inert gas injection to accelerate the mass transfer, injection of high surface reactants to improve the refining efficiency of the effective new processes, The new method has been put into industrial application. In this situation. The above new technology as much as possible, organically applied to electric arc furnace smelting process, is a meaningful issue. Current EAF steelmaking process is currently the main status: 1. The furnace is still as a comprehensive equipment for low-load operation. The performance of the heat transfer in the implementation of the power curve system, in the pass
