Stainless steel seamless tube manufacturing process

Stainless steel seamless tube manufacturing process

The high degree of continuous and high quality control of 304 precision Stainless steel tube cold rolling production will inevitably develop into a complete control of the process and production of the computer.

Stainless steel tube blank preparation. Including Stainless steel tube blanks, Stainless steel tube blanks (shear or gas cut), stripping and grinding, flaw detection, and high-alloy Stainless steel tube blank Surface treatment (such as pickling) and cold centering. Stainless steel tube billet heating. Usually, heating is performed in a ring heating furnace or an inclined bottom tube billet heating furnace, and the tube blank is generally sent to the piercing process by heat centering after being discharged from the furnace.

Perforation. The solid round steel is rolled into a hollow thick-walled Stainless steel tube, which is usually perforated by a two-roll or three-roll cross-rolling punch. If the Stainless steel tube blank is a steel ingot or a continuous casting billet, it can be punched in a hydraulic press or rolled on a two-roller (longitudinal rolling) pressure puncher-P.P.M. rolling mill. Rolled Stainless steel tube. In order to further reduce the diameter of the hollow capillary tube, the capillary tube must be processed into a waste tube on the tube mill. For the automatic rolling mill, after the stainless steel pipe is rolled, it is evenly homogenized by the homogenizer.

The Stainless steel tube is reheated and reduced in diameter. In order to finally obtain the required finished pipe, the waste pipe is usually reheated, and then processed on a sizing machine, a reducer, a tension reducer or an expansion machine to obtain finished stainless steel pipe stainless steel pipe of various specifications and sizes.
