摘要
介绍了冲天炉和中频炉熔炼铸铁的炉渣成分及来源,提出减少铸铁内部非金属夹杂物的措施:(1)提高铸铁的冶金质量;(2)改善铸铁中非金属夹杂物的形态及分布。描述了铁液二次渣的形成原因,认为采取适宜的措施及铁液处理技术,可以减轻铁液二次氧化及其不利影响。
The composition and source of slag of cast irons melted in cupola and medium frequency furnace was introduced. The measures to reduce non-metal inclusions in cast irons were proposed as follows： （1）improving metallurgical quality of the cast irons; （2）improving the morphology and distribution of the nonmetal inclusions. The formation reason of the secondary slag was described. It’s considered that, by adopting proper measures and iron melt treating technique, the secondary oxidation of the iron melt and its harmful effect can be reduced.
