炼钢技术的发展,不仅要使新的炼钢装置具有高产量,而且还要不断改善产品质量,降低消耗和不断提高金属收得率。为了达到这些目的,钢液的浇铸与凝固的关键作用越来越为国内外炼钢工作者所重视。近20年来,欧美、日本和苏联等工业发达国家都在出钢后工序上进行了大量的科学技术研究工作,开发了许多新技术、新工艺。如挡渣出钢、钢包整体内衬、滑动水口、绝热板保护渣和防缩孔剂“三位一体”的浇钢技术、大钢
The development of steelmaking technology not only makes the new steelmaking plant with high output, but also continuously improves the product quality, reduces the consumption and continuously improves the metal yield. In order to achieve these goals, the key role of molten steel casting and solidification more and more attention by domestic and foreign steelmaking workers. In the recent 20 years, industrialized countries such as Europe, the United States, Japan and the Soviet Union have carried out a great deal of scientific and technological research on the post-tapping process and have developed many new technologies and technologies. Such as slag-tapping, ladle lining the whole, sliding nozzle, insulation powder and anti-cratering agent “Trinity” of steel, steel
