冷轧Ti-IF钢化学成分与伸长率关系回归分析及其优化控制

Regression analysis of the relationship of chemical compositions and elongation of the cold rolled Ti-IF steel and its optimization control

通过统计回归分析,得到了钢中碳、氮、全氧、过剩钛、磷、硫、酸溶铝、残余元素等化学成分与柳钢Ti-IF钢伸长率的关系式,提出了优化柳钢DC05级Ti-IF钢化学成分的目标及控制措施,满足了特殊用户的个性化需求。

Through statistical regression analysis, the formulas for the chemical compositons such as the carbon, nitrogen, total ox- ygen,extra titanium, phosphorus, sulfur, acid-soluble aluminium and residual elements in steel and the elongation of the Ti-IF steel were found out. The target and control measures to optimize the chemical compositions of Ti-IF steel of DC05 grade were put forward.
