During the casting of heavier ingots, internal porosity occurs during solidification due to shrinkage of the cast metal. Porosity, or non-metal-filled areas, is up to several centimeters inside large ingots. The present work deals with the study of physical-metallurgical parameters of casting a large circular ingot, leading to the elimination of porosity. Which was done using the numerical software Magma 5.4. In order to find the most suitable casting conditions, the planned experiment method called DoE was also partially used. Particular attention was paid to casting speed with investigation and finding the most suitable casting temperature. For the basic variant cast in the Magma software, an initial investigation of the temperature field and voltage state during the ingot cooling in the numerical software Forge NxT 2.1 was performed.During the casting of heavier ingots, internal porosity occurs during solidification due to shrinkage of the cast metal.
