dc.description.abstractTo eliminate shrinkage defects in large steel ingots, a method of external influence combining electroslag heating and metal stirring during solidification has been proposed. Laboratory-scale experimental melts were carried out to produce 120 kg ingots of 40Cr steel. Longitudinal templates were cut from the obtained ingots, followed by macroscopic structure analysis, tensile tests and Brinell hardness measurements. The conducted studies demonstrate the elimination of shrinkage defects and an improvement in the physical homogeneity of the ingot as a result of the combined external influence, indicating the promise of this approach.
