The Formation of Cracks in Cast-Iron Molds during the Casting of Zinc Blocks

Abstract:

The article considers the problem of cracks formation in cast-iron molds during the casting of zinc blocks. The analysis of casting technology for manufacturing of cast-iron molds is performed. Changes of the construction of cast-iron molds is implemented to ensure the directional solidification. The analysis of thermal cycles of cast-iron molds during its operation is performed. It is established that the most dangerous moment of crack formation is the beginning of the pouring of molten zinc in the cold cast-iron mold. The new composition of the separation insulating coating, which reduces thermal shock and the probability of crack formation is developed.
