摘要
根据R10.5 m弧形圆坯连铸机的现场实际情况,建立了圆坯凝固数学模型。用现场铸坯表面温度的测量数据,修正了模型中的传热系数,使模型计算更加准确。在此基础上,成功地开发了Φ400 mm圆坯连铸的二冷工艺制度并应用于实际生产。生产的钢种有20#、34Mn5V、26Cr Mo4等,其铸坯内部质量全部合格。
In this paper, according to actual situation of round billet caster （R10. 5）, the solidification mathe-matical model is built. By measuring surface temperature of strand on the site, the heat transfer coefficient ofmodel is modified, which makes the model calculating result more accurate. On this basis, the secondary cool-ing system of 400mm round billet caster is successfully developed and applied to actual production. The produc-tion of steel 20#, 34MnSV, 26CrMo4 etc., the internal quality of round billet is qualified.
