钢铁冶炼目前所形成的工艺流程主要有:以铁矿石为主要原料的高炉——转炉流程,以废钢为主要原料的电炉流程。随着技术的发展,以占地少、投资省、建设周期短、能耗低,劳动生产率高、环境污染小、适应性强、技术不断创新的电炉短流程炼钢,在70年代得到了迅速的发展,而且60％以上的短流程采用超高功率电炉——精炼——连铸或薄板坯连铸——连轧构成的紧凑式生产过程,其优越性表现为:
Steel smelting process currently formed are: iron ore as the main raw material blast furnace - converter process, scrap as the main raw material of the electric furnace process. With the development of technology, EAF was rapidly developed in the 1970s with less land occupation, less investment, shorter construction period, lower energy consumption, higher labor productivity, less environmental pollution, better adaptability and constant technological innovation , And more than 60% of the short process using ultra-high power electric furnace - refining - continuous casting or thin slab continuous casting - continuous compacting consisting of compact production process, the superiority of performance as follows:
