Abstract:

In this paper we propose a new technology for processing of steel-smelting slag with 0-10 mm size fraction, which allows to obtain a number of highly efficient products without briquetting. With purpose of more complete extraction of metal from steel-smelting slags, the authors have taken into account the technological processes in the ore-heating electric furnaces, and on that basis, there has been proposed a single-phase furnace with hollow electrode which allows to remove of gases generated in the process of smelting.
