refractory materials are an indispensable part of high-temperature industrial equipment, and their maintenance and maintenance work is very important, which can extend the service life, improve efficiency and reduce production costs. Here is to introduce the maintenance steps of refractory materials.
1, regular inspection: regularly check the damage and cracks on the surface of the refractory. For the damaged and cracked places should be repaired in time to avoid further expansion.
2, cleaning and maintenance: clean the contaminants such as ash and chemical substances deposited on the surface of the refractory to prevent them from corrosion and erosion of the refractory. In addition, for chrome-containing materials should be careful to avoid the use of acidic solutions or acidic cleaners, so as to avoid the dissolution of chromium ions.
3, dredge the channel: for the import and export and pipeline channels, to regularly dredge to prevent blockage, affecting normal production.
4, strengthen protection: When the refractory is subjected to the alternating effect of high temperature and cooling, there will be an obvious thermal expansion and contraction effect, which is easy to lead to cracking or falling off of the refractory. Therefore, the protection can be strengthened by means of ceramic fiber felt and silicon carbide coating.
5, preventive measures: For some refractory materials susceptible to high temperature corrosion and oxidation, special preventive coatings can be sprayed on the surface to improve its corrosion resistance and service life.
6, installation quality: The installation quality of refractory materials is also very important, should ensure that its installation is firm, sealed and meet the design requirements. In addition, in the process of use, attention should be paid to timely handling of problems that may affect safety, such as leaks, explosions, etc.
In short, the maintenance of refractory materials needs to do regular inspection, cleaning and maintenance, strengthen protection, preventive measures and installation quality and other aspects to ensure its normal operation and extend the service life. In the specific operation, it is also necessary to formulate corresponding maintenance plans and measures according to different types of refractory materials and different use environments.
