The article considers initiation of cooling stresses of elastic-plastic deformation of “slag pot” castings, a factor which leads to casting-wall discontinuity and pull-crack defects. A mathematical model has been built and the casting-mould force interaction has been calculated basing on algorithms proposed by the author.

Quantities of total stress state in the casting wall during crack formation have been determined. It has been found out that bending stress making up 96% of the casting tensile strength value has a greater impact on defect formation. Process techniques to reduce pull-crack formation in castings have been proposed on the basis of the work results.
