Corrosion-Erosion-Resistant Carbon-Containing Refractories for Nonferrous Metallurgy Units

Abstract

Results are provided for development of optimum technology for preparing periclase-carbon refractory (PCR) by introducing carbon and antioxidizing agents into periclase refractory in different ways, i.e., pressing or vacuum impregnation with coal tar paste. Lining zones are determined within which use of PCR is rational. PCR refractories are tested and introduced into the slag belt of a reverberatory furnace in the Krasnoural Copper Smelting Combine, and KhPT refractory impregnated with carbon paste is introduced into the lining of Chelyabinsk Electrolytic Zinc Plant and Ust’-Kamenogorsk Lead-Zinc Combine Waelz kilns. Use of this lining increased a unit campaign by 40 – 45%.
