基于二次精炼技术的迅速发展,现代冶炼工艺已能生产出超低[O]、超低[S]的清洁钢水。然而,这种清洁度能否最终体现在成材上,还有赖于浇铸工艺的完善。否则,就可能功亏一篑。因此,随着连铸保护浇注技术不断完善的同时,模铸注流保护技术也取得了很大的进展。现将近年来国内外模铸注流保护技术的情况加以简介。 Based on the rapid development of secondary refining technology, modern smelting process has been able to produce ultra-low [O], ultra-low [S] clean steel. However, this cleanliness can ultimately be reflected in the finished material, but also depends on the improvement of casting process. Otherwise, it may fall short. Therefore, with continuous casting continuous casting protection technology, mold injection flow protection technology has made great progress. Now in recent years at home and abroad die casting injection protection technology to be briefed.
