| Abstract: | Semi-solid billets with different diameters of A357 alloy were produced on a pilot machine by electromagnetic stirring continuous casting. The effects of such processing parameters during the production as the intensity of electromagnetic stirring, casting speed, the flow volume of cooling water and the pouring temperature of melt on the quality of SSM billets and process stability of continuous casting were studied, and a set of proper parameters were established , which can be used to guide the industrial production of SSM billets. |
