Production Process of 6005A Alloy with Complex Section for Rail Transit
Extrusion of sections with large width-to-width ratio,width-to-thickness ratio,and wall thickness difference mostly uses friction stir welding,which imposes strict requirements on the butt welding gap between sections,making the production of sections more difficult.This article aims to solve the production difficulties of profiles with large wall thickness differences in terms of mold structure,extrusion technology,and especially online quenching technology,and improve the overall side bending of profiles.In addi-tion,it is necessary to make statistics on the lateral bending situation of the partial positions of the profiles,clarify the positions,and avoid collision during the fixed length sawing process to ensure the smooth supply of complex cross-section profiles.
