摘要

系统研究了半固态AlSi7Mg合金连铸坯料的制备和触变成形。研究表明:在电磁搅拌下

制备出半固态AlSi7Mg合金连铸坯料

合适的连铸速度为1.5～3 mm/s;半固态AlSi7Mg合金坯料的合适加热温度为580～590℃;在模具温度100～300℃和比压15～25 MPa条件下

触变锻造出汽车制动总泵体和比例阀毛坯。

Abstract

The nondendritic semi-solid AlSi7Mg alloy billet cast continuously and its thixoforging has been studied systematically in this paper. The results show that the billets of Semi - Solid AlSi7Mg Alloy cast continuously at the rate of 1.5- 3 mm/s can be made under electromagnetic stirring

that the proper reheating temperature of the billets is from 580 ℃to 590 ℃

and that when the die mould temperature is 100 ℃ to 300 ℃ and the pressure is 15 to 25 MPa

the master brake cylinders and scale valves can be thixoforged successfully.
