摘要
为满足成品棒材组织结构的要求 ,生产齿轮钢、高碳铬轴承钢等合金钢的连铸坯断面直径在3 5 0mm以上为宜。减少中间包钢水过热度 ,采用铸模电磁搅拌和低速浇铸等可防止柱状晶裂纹和减少中心疏松和偏析。
It is available that the concasting bloom section diameter of alloy steels such as gear steel and high carbon chromium bearing steel shall be more than 350 mm to satisfy the requirement of structure of finished products. The columnar zone crack could be prevented and the centre porosity and segregation decrease by decreasing superheat of metal in tundish, using electromagnetic stirring and low casting velocity.
