世界炼钢技术正在朝节资(源)省能化、节约劳力化、自动化及无公害化方面发展。面对这一发展趋势,转炉炼钢技术朝两个大的方向演进,1)仍保持原有炉型的新炼钢方法的开发;2)继续维持以转炉顶吹为特征的技术改革。前者以七十年代初出现的氧气底吹转炉为代表。与顶吹法相比,具有金属消耗低,吹炼平稳,精炼速度快,可控性强等优点。后者是指顶吹法的改进,近年来其进展是很大的。诸如提高炉龄的热喷补和白云石造渣技术,副枪检测的电子计算机动态控制以及能回收烟气物理热和化学热的高效节能装置等。针对顶吹法的不足,最近出现了两项引人注目的技术变革,一是经炉底
The world steelmaking technology is developing toward the capital (source) province energy saving, labor-saving, automation and pollution-free. Faced with this trend of development, converter steelmaking technology has evolved in two major directions: 1) the development of a new steelmaking method that maintains the original furnace type; and 2) the continued technical reform characterized by top blowing of the converter. The former is represented by the oxygen bottom blowing converter appearing in the early 1970s. Compared with the top blowing method, with low metal consumption, blowing smooth, refining speed, controllable and so on. The latter refers to the improvement of the top-blowing method and its progress has been great in recent years. Such as thermal gunning and dolomitic slagging to improve furnace age, electronic computerized dynamic control of sub-gun detection and high-efficiency energy-saving devices that can recover the physical and chemical heat of flue gases. For the lack of top-blowing method, there have been two recent dramatic technological changes, one through the bottom of the furnace
