FIELD: process engineering.
SUBSTANCE: invention relates to methods of producing reinforced steel parts, for example reinforced rings. Proposed method comprises fabricating steel base with cavity in the form of groove, producing hole on said base side and welding branch pipe therein. Then porous half stuff from carbide metal powder is fitted into said groove, and impregnated alloy is fitted on said half stuff, the impregnating alloy having liquidus temperature lower than that of the belt melting. Steel cover is welded to said base on the groove face side by continuous seam, vacuum system is connected to said branch pipe and base cavity is evacuated. Now produced assembly is placed into furnace with its working zone communicated with atmosphere to heat it to temperature exceeding impregnating alloy liquidus temperature and lower than base melting point, and half stuff is infiltrated by impregnating alloy.
EFFECT: higher efficiency, simplified process.
