Based on the data of in-place dynamic testing, the rolling pressure and rolling torsion of a Φ350 piercer have been tested, the maximum rolling pressure and rolling torsion were obtained for rolling pipes with different materials, manufacturing manners and length.

以现场动态测试数据为依据,对Φ350穿孔机的轧制压力和轧制扭矩进行了测试,得出了该穿孔机在轧制不同的材质、型号、长度管坯时最大的轧制压力和轧制扭矩,为该穿孔机的生产质量保证和改型设计提供了可靠的试验数据。

the formula of roll torque is all experienced formula or half experience formula, but the computation don't apply to the prodoction.

轧制扭矩的计算公式均为经验和半经验公式 ,计算结果与实际相差较大 ,为取得轧制扭矩的精确值 ,必须对轧机进行实际的测试。
