摘要

提出了"铸造-热处理一体化"新工艺

即对出模后的铸件直接进行热处理。该工艺利用铸件的余热

实现铸造和固溶处理的连续作业

可缩短固溶阶段的升温和保温时间。与T6工艺相比

固溶工序耗时缩短50%以上

能耗减少35%以上。Al-Si-Cu-Mg系铸造合金经铸造-热处理一体化工艺处理后

抗拉强度达310MPa

伸长率为2.3%

在相同的条件下

其强度和塑性都与经T6工艺处理的铸件接近。

Abstract

The casting-heat treatment integration process was put forward to treat Al-Si-Cu-Mg alloy.In the new process

the castings were put into heat-treatment furnace immediately after stripping the die.By utilizing the waste heat of the casting process

casting and solution treatment were conducted consecutively.In solution treatment process

more then half of man-hour and about 35% of energy consumption of traditional T6 heat treatment process can be cut in the integration process.After heat treatment in T6 process and integration process

Al-SiCu-Mg alloys have comparable mechanical performance

where the tensile strength and elongation reach 310 MPa and 2.3%

respectively.
