Discussion on Hot-extrusion Process for Seamless Steel Tube

Briefed in the article are the general hot-extrusion processes for seamless steel tubes and shaped tubes, including several manufacturing methods to produce hollow blooms as used to make hot-extruded seamless steel tubes.Described here are the main aspects of the 16.3 MN pipe extrusion plant, covering the extruder proper, the mechanical auxiliary equipment, the run-out system, the hydraulic drive system and the electric control system, etc.The hot-extrusion process is capable of turning the metal bloom into final tubular or sectional product with only one operation step, and easily getting the high deformation steels formed as tubes, being an ideal solution to produce seamless tube in high alloy or high deformation steels and various shaped seamless steel tubes as well.
