Method for preparing metal semi-solid slurry through preheating treatment SIMA method

The invention discloses a method for preparing metal semi-solid slurry through a preheating treatment SIMA method, and belongs to the field of metal semi-solid slurry. The method comprises the steps that firstly, a metal blank is preheated, then multi-pass multi-direction large-deformation cold rolling is conducted, then the blank is heated to a semi-solid temperature interval to be subjected to isothermal treatment, and metal semi-solid slurry is obtained after water quenching. According to the method, the metal semi-solid slurry is prepared through annealing, large-deformation cold rolling and isothermal treatment, the method has the characteristics of being high in preparation efficiency, accurate in process control, high in slurry quality and the like, and the metal semi-solid slurry which is uniform in structure, uniform in component, round and fine in solid-phase particle and uniform in solid-liquid distribution can be prepared. 本发明公开一种预热处理SIMA法制备金属半固态浆料的方法，属于金属半固态浆料领域。本发明所述方法为：首先对金属坯料进行预热处理，然后进行多道次多向大变
