Study on the Vertical Extrusion Process of Ultra-Thick Seamless Steel Pipe
Using the method of physical simulation, the vertical extrusion process of thick-walled seamless steel pipe is studied. According to the study and analysis focusing on the die structure and lubrication condition, optimized die parameter which is used for hot extrusion of ferrous metal and a reasonable die - billet composite lubrication program are achieved. Necessary reference and basis are provided to master not only the extrusion process of large diameter thick-walled long pipe, but also the quality control technology.
