METHOD OF HOT RELINING OF COKE OVENS AND GAMMA-2KS THERMITE MASS FOR METHOD EMBODIMENT

摘要

metallurgy. SUBSTANCE: method includes application to hot refractory surface of thermite mass including silicon powder, manganese concentrate and fireclay into which sodium chloride and water are introduced to obtain mixture of viscous-plastic state. Thermite mass for hot relining of coke ovens contains, wt, %: silicon powder 10- 19; manganese concentrate 19-21; iron-ore concentrate 49-51; sodium chloride 1- 3; the balance fireclay. Temperature of self-ignition of thermite mixture is 850- 900 C. EFFECT: higher service properties of produced lining. 4 cl, 1 tbl
