结合鞍山地区原材料条件制定出硅灰石渣、高炉渣和水泥熟料渣三种渣系。设计出10个试验保护渣,经试验,ACC-9号渣为最佳保护渣。ACC-9号渣吸浮夹杂能力很强,具有较好的化学稳定性和热稳定性,在熔化温度、熔渣粘度及火焰铺展性等方面都是比较理想的,完全能满足连铸机的生产要求。经工业试验,铸坯表面原始合格率达91.18%,比50号渣提高6.73%。 Combining with the raw materials in Anshan district, three types of slag systems, wollastonite slag, blast furnace slag and cement clinker residue, were worked out. Design 10 test flux, the test, ACC-9 slag is the best mold flux. ACC-9 slag floating ability to contain a very good, with good chemical stability and thermal stability, in the melting temperature, slag viscosity and flame spreading and so on are more ideal, fully able to meet the caster Production requirements. After industrial tests, the original pass rate of slab surface was 91.18%, which was 6.73% higher than that of No. 50 slag.
