40Cr steel Solid billet through inspection and clear surface defects cut into the required length, centering on the tube billet perforation end face and then sent to the furnace heating on the punch punch in perforated revolve and progress at the same time, under the action of roll and head, tube billet internal gradually formed cavity capillary, then sent to plug mill continue rolling finally after all the machine all the whole wall thickness, the sizing machine sizing (reducing), meet the specification requirements, using the continuous tube rolling unit production of hot-rolled 40Cr seamless steel tube is more advanced methods, if you would like to get a smaller size and better quality 40Cr seamless tube, Must adopt the method of cold rolling cold drawn or both combined cold rolling is usually conducted on two-high rolling mill, steel pipe in variable cross section round hole groove and the conical head of annular groove of rolling, cold drawing usually on a single or double chain chain cold drawing machine extrusion method is heated 40Cr  tube billet in airtight extrusion cylinder hole rods and extrusion, extrusion from smaller extrusion die, this method can produce smaller diameter of 40Cr steel pipe.
