在无缝钢管生产中,热轧穿孔工序是过程控制的龙头工序,管坯穿孔对冷拔和成品质量影响较大,而二辊斜轧穿孔机是热轧穿孔生产所用的重要设备。笔者结合二辊斜轧穿孔机特点和工作原理,对无缝钢管二辊斜轧穿孔技术进行了创新研究和应用,提高了钢管产能,保证了产品质量,为企业创造良好的经济效益。
In the production of seamless steel pipe, the hot-rolling perforation process is the leading process of the process control. The perforation of the blank tube has a great influence on the cold drawing and the finished product quality. The two-roller oblique perforation machine is an important equipment used in the production of hot-rolled perforation. Combined with the characteristics and working principle of two-roll inclined-hole piercing mill, the author made an innovative research and application of the two-roll oblique-piercing piercing technique of seamless steel pipe to improve the productivity of steel pipe, ensure the product quality and create good economic benefits for the enterprise.
