结晶器内坯壳变形遵循金属超塑性变形理论,根据金属超塑性变形理论对结晶器在线热态调宽液压缸推力进行了计算,提出了计算结晶器调宽速度的数学模型,得出了拉速与调宽速度之间的函数关系,推导出在线热态调宽过程中液压缸推力的计算方法。
According to the theory of superplasticity of metal, the thrust force of hot line broadening of the mold was calculated according to the theory of metal superplasticity. The mathematical model for calculating the width of crystallizer was put forward. Speed and width of the speed of the function as a function of the hot line width is deduced to calculate the thrust of the cylinder.
