Effects of technological parameters in strong cooling with single-tube on microstructure of A356 alloy semi-solid billets were described. The results show that fine grain in prepared billets is approximately spherical structure with pouring at 640～650℃ and cooling at 180L/h, meeting the requirements of semi-solid forming for billets.
