摘　　要：根据某中板厂生产现场16MnR中厚板现场部份实测数据进行采集,对中厚板的抗张性能与工艺参数的开冷温度、终冷温度、辊道速度、上下集管的开启总数目的关系进行定量研究,用多元线性回归分析建立了二者之间的数学模型,并且对所建立的回归方程和回归系数做了显著性检验,进而说明了工艺参数的开冷温度、终冷温度、辊道速度、上下集管的开启总数目对屈服强度极限和抗拉强度极限的影响是十分显著的,为现场控制冷却工艺改进提供依据。Based on actual measuring data for part of 16 MnR medium and heavy plates collected on site in anshan iron and steel company,quantitative research is carried out concerning their relationship between tensile properties and home cooling temperature,end cooling temperature,roller speed,total opening number of fluctuation manifolds,then a mathematical model between them is established by adopting multiple linear regression analysis,which regression equation and regression coefficients established is tested in its significance.Furthermore,the significant impact of home cooling temperature,end cooling temperature,roller speed and total opening number of fluctuation manifolds on yield strength and tensile strength is stated,which provides a basis for improving the controlled cooling process on site.
