根据轧辊的热胀和冷缩随时间变化规律 ,建立了在线应用的工作辊热凸度预报模型 ,并从理论及实测数据两方面分析了精轧各架轧辊热凸度及其对出口板凸度的影响 ,为板凸度和板形的控制奠定基础。
According to the law of thermal expansion and shrinkage of the roll over time, the prediction model of working roll thermal crown of the roll was established. The thermal crown of each roll of the finishing rolling was analyzed from the theoretical and measured data, Degree of influence for the plate crown and shape control laid the foundation.
