摘　　要：应用统计过程控制技术分析了热轧工序关键工艺参数卷取温度的控制水平，运用Minitab软件绘制卷取温度X^--R控制图和工序能力分析图，得出了工艺过程处于受控状态的结论，并提出了改进质量的措施。对持续提升产品质量和降低生产成本具有重要意义。The control level of hot-rolled key process parameter, statistical process-controlling technology. Coiling temperature capability analysis chart are drawn using Minitab software, controlled state is obtained and the improvement measures are product quality improvement continuously and cost reduction. coiling temperature, is analyzed by X^--R controlling chart and process the conclusion with process in a put forward. It is significance for product quality improvement continuously and cost reduction.

关 键 词：统计过程控制 X^-R控制图 工序能力
