    摘要: In a method of producing ingots of unalloyed and alloyed steels having an improved primary crystallization, reduced ingot segregation and a reduced content of non-metallic inclusions, liquid steel is poured into a mould in an amount substantially approximately equal to the desired weight of the ingot to be obtained, slag is applied to the steel and energy is supplied to the already melted slag to maintain the liquid core zone of the slag at a high temperature, while the walls laterally confining the slag are cooled to create and maintain a layer of solid slag in that area, the energy supply to the slag is effected by resistance heating by means of at least one consumable electrode having a chemical composition identical or similar to that of the ingot, and the quantitative composition of the at least one consumable electrode is selected in a manner as to obtain a concentration of segregating elements in the amount of steel melted off per time unit that is lower by that amount in which the concentration of segregating elements increases per time unit in the remaining melt of the ingot.
