【摘要】 16Mn钢中加入 0 .0 1%钒、钛 ,110 0℃开轧、85 0℃终轧 ,分别在奥氏体再结晶区及奥氏体未再结晶区控制轧制 ,轧后给以 3～ 4℃冷却速度控制冷却 ,得到的轧件组织细小、带状珠光体明显减少 ,钢材的各项性能指标均得到了较大的提高。利用MATLAB数据处理软件对轧制工艺参数与材料的性能之间的关系进行了多元线性回归并进行优化 ,得到的回归公式及优化结果对建立中厚板轧制工艺—组织—性能在线控制专家系统的建立具有重要的指导意义 ;利用该回归及优化结果 ,可根据轧制时的基本工艺及轧件的化学成分 ,预测轧件的性能指标 ,为轧制工艺参数的实时调整提供重要的依据更多还原

【Abstract】 Adding 0.01% Vanadium and Tianium to 16Mn steel, the tiny organize can be obtained, banded pearlite can be reduced and the property index of the steel is raised when rolling begin at /100 ℃ and controlled rolling in austenite recrystllization area and unrecrystllization area,then cooling with 3～4 ℃/s. The author applied the MATLAB to linear regression and optimization for the relation between the rolled technological parameter and function of material. The result is useful for establishing the on line control expert system for the relation between rolled technological parameter an organize and function. The function of material according to the chemical composition and the rolled technological parameter can be predicted,so it is an important basis for adjusting the rolled technological parameter timely.更多还原
