Abstract: The installation of castable anchoring nails is an important link in the construction and renovation of high-temperature industrial furnaces, which affects the performance and service life of the furnaces. The installation density needs to be determined based on factors such as working temperature and lining material thermal expansion coefficient, and the spacing is usually between 100mm and 200mm. The construction requirements include foundation preparation, material selection, anchorage length, pouring construction, and maintenance and use. Taking into account various factors, strict control of installation density and construction requirements can prolong the service life of the furnace, improve production efficiency and economy.
In the construction and renovation process of high-temperature industrial furnaces, the installation of castable anchoring nails is an important link. Correctly mastering the installation density and construction requirements of castable anchoring nails is the key to ensuring the quality of castables.
The installation density of castable anchoring nails mainly depends on factors such as the working temperature of the furnace, the coefficient of thermal expansion of the lining material, and usage conditions. In general, the installation spacing of anchor nails for pouring materials should be controlled between 100mm-200mm, and the specific values should be calculated and determined according to the actual situation. If the installation density is too small, it may lead to waste and increase construction costs; If the installation density is too high, it may affect the thermal expansion of the lining material and the heat dissipation performance of the furnace.
The material used for anchoring nails with castable should be of stable and reliable quality, and ensure that the material has high high-temperature performance, mechanical strength, and corrosion resistance. At the same time, special attention should be paid to the factory inspection and on-site re inspection of materials to prevent unqualified materials from entering the construction site.
