Abstract

In this paper, the solidification structure of hypoeutectic grey iron under different vacuum conditions in lost foam casting (LFC) were discussed. In order to better research solidification structure under different cooling conditions, we designed different thickness step test casting and took actual casting experiment in two vacuum degree environments (0.02MP and 0.055MP). By setting the thermocouple to the cooling curves during the mold filling and solidification process is recorded at the center of different thickness step. Finally, through the use of thermal analysis and metallurgical comparative analysis, the solidification structure feature of hypoeutectic gray cast iron in lost foam casting process by vacuum degree environments is demonstrated to guide designer to advance the casting processes design.
