Abstract
Temperature distribution in linings of horizontal converters of copper-nickel industry during different exploration conditions is the object for researching. The aim of the work is the researching thermal conductivity of refractory lining of converters, composed different refractory products not only initial content but also saturated with copper-nickel mattes. The brickwork temperature in cross-section can be evaluated with the results of researches. Therefore it has been calculated the thickness of lining wherein the sintering processes of different laying solutions of refractory back filling (including firing of self-priming  high-temperature synthesis) have been happened. The heating of converters lining with burners for prevention temperature reducing of laying low than 700–800 oC (the start of matte solidification), that is the causes of lining spading by 40–80 mm has been realized for prevention laying damaging as the result of thermal stress.
keywords Spading of refractory product, temperature of roasting, matte, thickness of refractory materials saturated with mattes, physical model, coefficient of heat conductivity, heat-conducting back fillings, protecting coatings, self-propagating high-temperature synthetic solution.
