Computational simulation of hot tearing susceptibility of steel harp casting in rigid fixation conditions

The work is devoted to the quantitative assessment of the hot tearing susceptibility of the steel harp casting which consists of several specimens having different lengths of a rigidly pinched thin part. During crystallization and subsequent cooling, shrinkage in the thin part of the specimens is realized as hindered contraction. It leads to localization of deformation in the transition from thin to thick the specimen parts. By varying the length of the thin part specimens, it is possible to determine how the coefficient of localization of deformation changes under the condition of rigid fixation. Quantitative analysis of the tendency to form hot cracks showed that an increase in the length of the thin part of the specimen by 3.3 times from 30 to 100 mm leads to a deterioration in hot tearing susceptibility at a temperature of 1300 °C by 42%, which is associated with the localization of deformation in the thin part of the specimen.
