Technology of manufacturing heat insulating refractories

Due to their low weight and low thermal conductivity, refractory heat-insulating materials can significantly reduce the weight of the lining of high-temperature industrial units and lower environmental heat leakage. The production technology of these types of refractories makes it possible to obtain highly porous products with sufficient strength and heat resistance. The technology was developed in the conditions of the production of aluminosilicate refractory materials at OOO Ogneupor and PAO MMK.
