Abstract
The invention discloses a coke oven ascending tube enameled brick and a preparation method thereof, which belong to the technical field of the refractory material. The coke oven ascending tube enameled brick is characterized in that glaze comprises the following components in part by weight: 50-65 parts of feldspar, 10-15 parts of quartz, 8-15 parts of stalactite, 5-8 parts of cooked talc, 9-15 parts of raw Datong and 6-10 parts of zircon powder. Because of high softening temperature and fusing temperature, the ascending tube is not softened and bonded under the normal working condition (800-900DEG C); the thermal conductivity coefficient and the density of the glaze are matched with those of the ascending tube enameled brick blank made of clay; and meanwhile, the glaze has a higher elastic modulus to ensure that the glaze has a higher thermal shock resistance. The coke oven ascending tube enameled brick produced with the preparation method has the characteristics that the surface carbon deposition phenomenon on the tube wall of the ascending tube can be reduced, and the cleaning times and the cleaning strength of the surface carbon deposition of the ascending tube are obviously lowered in the use process.
Description
technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a coke oven riser glazed brick. Background technique [0002] The rising pipe brick is the lining brick of the rising pipe on the top of the coke oven. It is used between the top brick of the furnace and the gas pipe. The normal working temperature is about 800-900 °C. The material is mostly clay refractory material. Under normal working conditions, the flue gas contains free carbon particles and CO, CO 2 During the smoke exhaust process, carbon particles are inevitably adsorbed on the surface of the riser. When the carbon particles adsorbed and deposited on the pipe wall reach a certain amount, it will cause the problem of poor ventilation and must be cleaned, thus affecting normal production. [0003] Most of the existing materials are clay refractory materials. Under normal working conditions, the flue gas contains free carbon particles and CO, CO ...
