The composition of such mixtures does not take into account the ash content of graphite. However, ash contains refractory components (SiO2, A12Oz, etc.) that contribute to the formation of coarse H1lac inclusions on the surface of the ingot and to the ingestion of the body of the ingot by nonmetallic inclusions. The purpose of the invention is to improve the quality of the ingot. This is achieved by the fact that the indicated components are taken in the following ratios, weight%: Graphite 60–79
