Environmental Technology for the Integrated Disposal of Man-Made Wastes of the Metallurgical Industry: Self-Curing, Chemically Resistant Refractory Mass1

Abstract

A review of environmental protection technologies for the integrated disposal of metallurgical industry waste is given. The results of studies on obtaining and determining the basic physicochemical properties of a new composition of self-curing, chemically resistant refractory mass are presented. The mass is comprised of industrial waste, including slag from electrothermal reduction of niobium pentoxide — crushed and purified fused Al2O3 (electrocorundum), and scrap of periclase-chromite articles. The mass has high chemical resistance, fire resistance, mechanical strength, hardness, wear resistance.
