Numerical Simulation Analysis of Continuous Extrusion Process of H62 Brass Alloy
Continuous extrusion technology is a new type of extrusion technology for manufacturing ultra long bars,pipes,and profiles.This production technology not only has high material utilization,but also significant energy-saving effects and high production efficiency.Based on the TLJ250 continuous extrusion machine,numerical simulation of the continuous extrusion forming process was conducted using DEFORM software,and the influence of extrusion wheel speed on the continuous extrusion forming process was analyzed.From the comparison of temperature and velocity fields,it can be seen that when the extrusion wheel speed is 6 r/min,the temperature difference between the center and edge of the fixed diameter belt of the billet is the smallest,about 89 ℃,and the flow rate difference is also the smallest,about 163 mm/s.
