CREATION OF OWN RAW-MATERIAL BASE FOR FOUNDRY PRODUCTION ON MACHINE-BUILDING ENTERPRISES

The article is devoted to the problem of processing dispersed metal wastes, generated at machine-building enterprises. The proposed solution of the problem is recycling in rotary tilting furnaces (RTF) with the production of high-quality charge materials (charge ingots) or foundry alloys directly at the enterprises where these wastes are formed. The results of experimental meltings of gray iron in induction crucible furnace with the replacement of traditional charge materials with ingots, obtained from chips, scale, sludge, etc. in the RTF are presented.
