Also analyzed are the deformation characteristics of the metal when conical roll is used and there exist both toe Angle and feedAngle.
分析了采用锥形轧辊，在辗轧角和送进角同时存在时金属的变形特点。
2
Relevant operation shows that owing to the change of the feedAngle piercing efficiency has been increased, net rolling time reduced, and unit energy consumption lowed.
生产实践表明，送进角改进后穿孔效率提高，纯轧时间减少，单位能耗降低。

From the model, the effects of the dip Angle and feed rate on thrust force are estimated.
