Regression analysis on end-point steel composition and temperature for top and bottom blowing converter;
顶底复吹转炉冶炼终点钢水成分及温度回归预测分析
For the quantity of triangular area crack and central area crack of SS400 slab,analysis is carried out on steel composition,degree of superheat,casting gap,etc.
针对SS400钢铸坯出现大量三角区裂纹和中心裂纹的现象,从钢水的成分、浇铸过热度、扇形段开口度等方面进行分析,通过采取控制钢水成分、保证铸机精度、优化二次冷却等措施,有效地控制了板坯的三角区裂纹和中心裂纹,铸坯一次合格率由94。
