The Effect of Heat Removal from the Casting Mould on the Crystallization High Silicon Cast Iron

Silicon cast iron with high chemical resistance, which is the biggest advantage of this material, did not have any competition for a long time. It was popular on the market of metal materials because of its low price. However, the production of this material requires special attention and precautions, which is a barrier for foundry. The article presents the results of research of high silicon cast iron crystallization based on thermal derivative analysis (which has identified characteristic temperatures of the investigated alloy crystallization process basis on the part of Fe–Si phase diagram and process analysis using calculations made in Thermo–Calc software) and metallographic analysis of the structure.
