New Technology for Refractory Material Preparation

Abstract

Use of cheap local raw material resources (barite and witherite concentrates of the Karagailinsk deposit, Arkalyk clay, chromite-magnesite scrap objects, copper production dump slag, chromite ore, etc.) makes it possible to create new import-substitution refractory materials. Non-traditional technology is created for obtaining moldable import-substitution refractory materials from cheap local raw material resources based on occurrence of self-propagating high-temperature synthesis (SHS). A number of new compositions are proposed for self-sintering refractory mixes, whose objects have good technical and economic indices.
