吸热圆管外径为34mm

壁厚为1.1mm。

Abstract

The effects of thermal equilibrium method semi-solid slurry process on microstructure of A356 aluminum alloy were investigated.Special processing apparatus was designed

and orthogonal experiment of three factor to three levels was designed by taking melt pouring temperature

the outer diameter of heat pipe and the wall thickness of heat pipe as orthogonal factors.In addition

the orthogonal optimized parameters were verified by experiment.The results reveal that the factors affecting microstructure of semi-solid A356 aluminum alloy is presented as follows:the wall thickness of heat pipe

pouring temperature and the outer diameter of heat pipe.The optimal process parameters were obtained by orthogonal experiment

which was the pouring temperature of melt of 630℃

the outer diameter of heat pipe of 34 mm and the wall thickness of 1.1 mm.
