摘要
根据宝钢 2 0 5 0mm机组粗轧实测数据 ,采用回归方法建立了轧件自由宽展和狗骨宽展的计算模型 ,其适用范围为钢板温度 95 0～ 130 0℃ ,板厚 4 0～ 30 0mm ,板宽 12 0 0～ 16 0 0mm ,计算绝对误差在 - 6～ +6mm范围内 。
The calculation models of rolled piece free spread and dog bone spread were established by regression method based on the measured datum of 2050mm mill of Baosteel The models are proper for plate which temperature is 950～1300℃,thickness is 40～30mm and width is 1200～1600mm The calculation absolute error is -6～+6mm,and it can be applied for industry production
