挤压模具液氮技术的推广及应用

Extrusion Die on Nitrogen Technology Promotion and Application

挤压成形技术是铝型材生产的主导环节和核心环节,因此如何保障型材的表面质量,缩短挤压时间,提高模具使用寿命成为挤压过程中的核心问题。而氮气冷却技术能有效地解决铝挤压中的温升问题,对提高铝型材挤压速度、延长模具使用寿命、改善型材表面质量和组织力学性能有显著的效果。

Extrusion forming technology is the main link and core link in aluminum production,so how to ensure quality of the surface of the material,shorten the time of extrusion,prolong the service life of mould is the core problem in the process of extrusion.And Nitrogen cooling technology can effectively solve the problem of the temperature rise in aluminum extrusion,and can improve the aluminum extrusion speed,lengthen the service life of the mold,and improve mechanical properties of material surface quality and microstructure.
