For the purpose of development of measures directed toward increasing the life of the VTR-20, the lining failure mechanism was investigated with the use of microscopic, x-ray diffraction, and analytical chemiacl methods of analysis. It was concluded that the life of the periclase lining of a high-temperature reactor in the production of ferrochrome is determined by a combiantion of factors which includes the high process temperatures, intense interaction of the molten material in the lining, impregnation of the refractory primarily by oxides of silicon and calcium, active mass exchange in the occurence of exothermic reactions, temperature variations in the working layer related to the periodic character of service of the reactor, and the presence of joints in the lining. Maintenence on the reactor lining of an ore-slag layer increases the reactor life by 25-50%.
