Electro-slag remelting is one of the ways to produce high-strength metal. For this reason, the machining of electro-slag metal is difficult. It is especially difficult to obtain a cylindrical billet from such a metal. The article proposes a new, high-tech method for producing a hollow ingot with electro-slag remelting. The production of a hollow ingot is obtained by introducing the melting point during melting. Due to the difference in the melting point between the base metal and the phase introduced, the low-melting material is forced into the center of the ingot that is being formed. The course of the experiment, the investigation of the macro- and microstructure, and the mechanical properties of the resulting hollow ingot are described.Keywords: Electro-slag remelting, low-melting material, hollow ingot, macro and micro structures, mechanical properties
