首钢总公司第三炼钢厂精炼设备ＬＦ炉近日投入使用。由此，他们生产的钢水杂质将减少５０％，轧制出的钢材质量明显提高，同时也标志着首钢开始从生产普碳钢向生产优质钢转移。炉外精炼使钢水质地纯洁精良。目前全世界共有炉外精炼设备２００多座，处理钢水占总钢产量的８０％ Shougang Corporation’s third steel refining plant LF furnace recently put into use. As a result, their production of molten steel will be reduced by 50%, and the quality of the rolled steel will be significantly improved. At the same time, it will mark the beginning of Shougang’s shift from the production of general carbon steel to the production of high quality steel. Out of furnace refining the quality of molten steel sophisticated. At present, there are more than 200 furnace refining equipment in the world, and the treated molten steel accounts for 80% of the total steel output.
