Popis: A low high-temperature tunnel kiln was rebuilt, including increasing the length of the firing zone, supplying hot air to the burners, supplying air to the cooling zone through the roof, and providing a system of aerodynamic sealing of the subhearth space of the kiln. Reconstruction of the kiln and the firing method developed made it possible to obtain a stable firing temperature of 1850°C and a hold of up to 6 h at a temperature above 1800°C, to decrease the temperature differential across the kiln channel cross section, to reduce scrap, to increase the quality of magnesia and magnesia-spinellide parts and the kiln productivity, and to improve the car serivce conditions and the working conditions of the operating personnel.
