通过 H 型钢轧件在万能孔型中的受力分析,直接推导出轧件对轧辊的前滑公式。用回归正交设计法对 H 型钢轧件的前滑进行了多因子的综合试验研究,组织了全因子试验,并得到了 H 型钢轧制时计算前滑的回归方程。与实测值相比,当腰部压下系数和凸缘压下系数取值相近时,理论公式能给出满意的结果。 By H-steel rolling in the universal hole in the force analysis, direct deduction of the roll of the rolling front slip formula. By regression orthogonal design method, the multi-factor comprehensive test on the forward sliding of H-section steel was carried out. The full factorial test was carried out and the regression equation for calculating the slip before H-section rolling was obtained. Compared with the measured value, the theoretical formula can give satisfactory results when the lumbar reduction coefficient and the flange reduction coefficient are similar.
