A method for repairing tunnel furnace cars.

The NPF Alineka company has developed refractory construction concretes BRSB20I11 based on water glass and concretes BRAB50I13 and BRAB50I15 with the traditional content of aluminate cement, which have a high class of thermal resistance (T140–T180) and the maximum application temperature of 1100–1500°C, as well as heat-insulating lightweight plates of size 300 × 200 × 80 mm and density 400 kg/m3, with a maximum application temperature of 1150°C. These materials can be used as lining of tunnel furnace cars for firing wall ceramics, as well as porcelain and faience products. The experience in repairing a furnace car is described.
