TECHNOLOGY ON LINE Producing Control of the Welding Mark at Aluminium Extrusion
铝型材挤压焊合线条纹的生产控制
-
Decreasing the extruding temperature , controlling the outlet operating temperature between 490 ~ 510 ℃ and enforcing the outlet quenching can improve the welding mark situation .
适当降低挤压温度，出口温度控制在490～510℃，加强出口淬火强度，抑制晶粒粗大，有利于焊合线条纹的改善。
