Fabricating of Steel/Cast Iron Composite by Casting Route

Abstract

In this study, 1.2333 cold work tool steel and cast iron (GG 25) were simultaneously melted in di erent furnaces to fabricate composite die mold used in sheet metal forming industry. To enhance the metallurgical bond between two components of composite part, the pouring temperature of cast iron was assessed just above the solidus temperature, then metallurgically prepared cast iron was poured on to the cast tool steel. The temperature and casting parameters were monitored and simulated. Experimental and simulation results were compared, nally the optimum parameters and casting route were revealed.
