摘要
研究了连铸工艺参数对于高碳钢小方坯内部质量的影响 ,结果表明 ,结晶器电磁搅拌强度增加 ,高碳钢小方坯中心碳偏析减小 ,但坯壳内的负偏析加重。在结晶器电磁搅拌条件下 ,随着二冷比水量增大 ,中心碳偏析减小 ;随拉速、中间包钢水过热度和钢中碳含量增加 ,中心碳偏析加重。
The effect of continuous casting process parameters on internal quality of high carbon steel billets was investigated. It was shown that with the M-EMS intensity increase, the central carbon segregation in billets decreased, but the negative segregation near the edge in billets became worse. Under M-EMS condition, with the increase of secondary cooling water flow rate and the decrease of casting speed, tundish superheat and carbon content, the center carbon segregation was improved.
