BG48727A1 - Surface of industrial furnace - Google Patents

Abstract

The lining can be applied in the field of metallurgy, machine building and ceramic industry. It features low accumulating ability, reduced losses from thermal conductivity, reduced thickness of the brickwork which provides for a reduced use of refractory materials, metal constructions and labour, reduced energy consumption for drying and heating up, sufficient mechanical strength, good gas sealing, minimal fuel consumption with furnaces with regulated cooling- during the cooling period and high durability. The surface consists of three layers. The first layer is chamot, class "A", the second layer is from light chamot or silica brick and the third layer consists of microporous insulating material. The microporous insulating material includes in weight parts: fireproof clay and/or kaolin from 20 to 50, liquid or solid water-soluble inorganic bonding substance 5 - 30, water 5 - 50 and a burning up of organic substances which have been soaked with the liquid inorganic bonding substance in advance - 50 - 180 volume parts with respect to the rest of the mixture.
