CPE(Cross-Rolling Piercing and Elongating)工艺是轧管工艺上的一个新组合。即先由斜轧穿孔,然后经管头收口机收口,再进入顶管机进行延伸,接着往下按常规的工艺,通过定径或者张力减径机、冷床、矫直、切管,生产热轧无缝成品钢管。其工艺流程见下图。 CPE (Cross-Rolling Piercing and Elongating) process is a new combination of pipe rolling process. That is the first by the oblique rolling perforation, and then by the first shut-mouth machine shut, and then into the top pipe machine for extension, and then down by conventional technology, through the sizing or tension reducer, cooling bed, straightening, pipe cutting, production heat Rolled finished seamless steel pipe. The process shown below.
