Abstract

The problems of the presence and formation of hexavalent chromium during smelting in electric arc furnaces are discussed. The schemes of gas cleaning systems from chromium-containing gases of electric arc furnaces DS-0,5 and DSP-1,5, The gas cleaning system of furnace DS-0,5 includes a cyclone, two Venturi scrubbers and an electrostatic precipitator. The gas cleaning system of DSP-1,5 furnace consists of a cyclone, regulated and diffuzor scrubbers and two electrostatic precipitators BVKO. It is shown that industrial production of fused chrome-containing refractories can be ensured under safe conditions by using the mentioned dust and gas cleaning systems. Ill. 4. Ref. 4. Tab. 1.

Keywords
