The Production Process
General seamless steel tube production process can be divided into cold drawing and hot rolled, cold rolled seamless steel tube production process generally more complicated than hot rolled, three-roll rolling tube billet must first, after the extrusion sizing test, if there is no response after crack on the surface of pipe have to be cut after cutting machine, cutting grow about a meter of billet. Then enter the annealing process, annealing to use acidic liquid pickling, pickling should pay attention to whether there are a lot of bubbling on the surface, if there are a lot of bubbling shows that the quality of the steel pipe can not reach the corresponding standard. The appearance of cold-rolled seamless steel pipe is shorter than that of hot-rolled seamless steel pipe, the wall thickness of cold-rolled seamless steel pipe is generally smaller than that of hot-rolled seamless steel pipe, but the surface looks brighter than that of thick-walled seamless steel pipe, the surface is not too rough, the caliber is not too much burr.
①The main production process of hot rolled seamless steel pipe ( main inspection process) :
Preparation and inspection of billet → heating of billet → perforation → rolling pipe → reheating of steel pipe → sizing (reducing) → heat treatment → straightening of finished pipe → finishing → inspection (non-destructive, physical and chemical inspection, table inspection) → storage
② The main production process of cold rolled (drawn) seamless steel tube:
Billet preparation → pickling lubrication → cold rolling (drawing) → heat treatment → straightening → finishing → inspection
