摘　　要：介绍了二辊立式斜轧穿孔机的轧制特点,通过对穿孔机轧辊和管坯接触面任意微小截面计算再求和的方法,忽略顶头和规圆区影响,沿轧制线方向进行简单积分,计算变形接触面积,推导出适用于二辊立式穿孔机轧制力工程计算的简化计算式;并与现场实测轧制力数据进行对比,验证了工程计算公式可以作为穿孔机设计的参考依据。The rolling process characteristics of the 2-roll vertical rotary piercing mill is described. A simplified formula for engineering calculation of the said piercing mill is derived with the procedures, i.e., calculating the arbitrary minute section of the contact surface between the piercer roll and the work piece, and then making the adding up; conducting the simple integral along with the rolling line and without consideration of the effects by the plug and circling zone so as to finally find out the deformation contact area. The calculation result from the said engineering formula is verified by means of comparison with the actually site-measured rolling data. The verification result shows that the formula is worth using as reference basis for design of the piercing mill.
