Description

Technical Field

[0001] The utility model relates to the field of thermal construction materials, in particular to a high-strength kiln ceiling brick. Background Art

[0002] The traditional kiln ceiling bricks are suspended by embedded stainless steel plates. This structure has high thermal conductivity during use and is prone to corrosion over time, which not only increases energy consumption but also has a great impact on the service life of the ceiling structure. In order to adapt to the rapid development of the kiln industry, it is urgently necessary to provide a new structure that can reduce thermal conductivity and increase service life when the kiln uses the ceiling structure, so as to meet the requirements of kiln product manufacturers for lower thermal conductivity and longer service life indicators of the kiln products in the ceiling structure.

[0003] After searching, it was found that the publication number is CN217358056U, and the name is modular ceiling bricks for kilns. The application proposes a modular ceiling brick for kilns with reasonable structure, convenient masonry, energy saving and consumption reduction, and extended life. However, during actual installation and use, the application still uses the traditional lifting structure. The staff needs to install refractory bricks one by one in the furnace, and each brick body is relatively independent. The overall firmness and strength have not been improved, and further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
