PQF连轧管机Φ163mm孔型设计

Φ163mm Groove Designed in PQF Mandrel Pipe Mill

本文以Φ159机组的生产工艺和生产技术为基础,对热轧生产线的PQF连轧机、脱管机等轧机孔型进行了重新设计,同时对轧制控制程序进行了修改和优化,经过多次理论分析和现场实践验证,成功设计出Φ163系列生产工艺,最终完成了工业试制、批量生产和供货。

After analyzing the rolling technology and the ability of device of 159 producing line, making full use of the existing production technology, pipe machine pass has been redesigned and PQF rolling mill. Mean- while, the program of mill control was modified and optimized. After several times theoretical analyzing and testing, the rolling technology of Φ163 size was successfully designed, the final completion of the trim production, mass pro- duction and supply.
