以冷却斜坡法为基础

通过自主设计的半固态制坯装置制备了7A09铝合金半固态坯料

利用正交试验法研究了浇注温度、斜管角度和立管转速对坯料组织的影响

并采用单因子试验法进一步研究了各因素对坯料组织形成过程的影响。结果表明

浇注温度对晶粒平均尺寸和平均形状因子影响最大

斜管角度次之

立管转速影响最小;合适的工艺参数为:浇注温度约为630℃

斜管角度在45°

0°之间

立管转速为70

00r/min。

Based on the cooling slope method

the semi-solid 7A09 aluminum alloy billets was prepared by the self-designed device.Effects of the pouring temperature

the angle of inclined tube and the rotating speed of straight tube on the microstructure of the billet were analyzed by orthogonal experiment

meanwhile

influence of every experimental parameter on the formation of the billet microstructure was further explored

respectively.The results show that the pouring temperature has the largest effect on the average size and shape factor of the grains

and then the angle of inclined pipe

then the rotating speed of straight pipe.The semi-solid billet with good quality can be prepared at the pouring temperature of approximately 630 ℃

the angle of inclined pipe between 45°and 60°as well as the rotating speed of straight pipe between 70r/min and 100r/min.
