FIELD: metallurgical industry; particularly, hardening and reconditioning of machine parts and also production of high-grade tool steels by method of electroslag remelting. SUBSTANCE: method includes introduction of tungsten-containing mineral materials in combination with flux. Height of molten flux is maintained within 40-60 mm. Tungsten-containing mineral materials are used in form of scheelite and/or wolframite concentrate with the following amounts of main components, wt.%: tungsten oxide 45-72; iron oxide 10-25; manganese oxide 2-10; silicon oxide 3-8. EFFECT: provided optimal conditions of concurrent slag remelting and alloying with obtaining stable properties over entire metal volume. 2 tbl, 2 ex
