向6063合金中添加一定量的混合稀土,并应用到工业化生产中,研究其对铸态组织和挤压过程的影响。结果表明:添加稀土后,对铝合金组织有着良好的改性作用,有少量的稀土相析出,铝合金的塑性提高。铝合金在进行挤压生产时所需挤压力减小,模具寿命提高,挤压速度变快,生产率提高。 Add a certain amount of rare earth mixed to the 6063 alloy, and applied to industrial production, to study the impact on the as-cast structure and extrusion process. The results show that the addition of rare earth has a good modification effect on the aluminum alloy structure, a small amount of rare earth phase is precipitated and the plasticity of the aluminum alloy is improved. Aluminum extrusion in the extrusion process required to reduce the pressure, increased die life, extrusion speed, productivity.
