Linings of heating equipment made with the use of refractory fiber thermal insulation materials are receiving ever increasing use. Their use makes it possible to significantly reduce the weight of heating equipment, heat losses to the environment, accumulation of heat by the lining, and fuel consumption and also to increase the productivity of heating equipment, especially batch furnaces such as bell furnaces.As a rule anchors of heat resistant steel, which are welded to the furnace shell by electric welding, are used for fastening of a lining of refractory fiber materials.The fiber materials are mounted on the anchors and fastened with metal or ceramic plates.Such a method of fastening of the lining requires the use of scarce heat resistant steel, a large volume of welding work, and the use of metal anchors through which the heat losses through the lining increase.Magnitogorsk Metallurgical Combine together with the Ukrainian Scientific-Research Institute for Refractories has developed a method of lining heating equipment with fiber refractory materials with an inorganic binder and the use of refractory cement.Thermal insulation fiber plates with a clay binder of unfired type MI
