    Investigation of the Solidification Behaviour of 40cr Steel Ingots Under Metal Heating and Stirring
    (Хмельницький національниий університет, 2025-12) Biktahirov, F.K.; Shapovalov, V.O.; Barabash, V.V.; Hnatushenko, O.V.; Ihnatov, A.P.
    To 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.

    The Influence of Metal Heating and Stirring on the Conditions of Steel Ingot Solidification
    (Хмельницький : ПП Заколодний М.І., 2023-12) Barabash, V.V.; Biktahirov, F.K.; Shapovalov, V.O.; Hnatushenko, O. V.
    The paper results from both physical modeling and full-scale experiments with liquid steel demonstrate that active control of crystallization processes during ingot manufacturing is achievable through the combination of steel heating and stirring the liquid core of steel ingots. This discovery unveils new possibilities for producing large, high-quality ingots.
