Tungsten crucible is a kind of industrial equipment which is made of tungsten metal in special process. It should be paid attention to maintain in the process of application, in particular, the maintenance of new crucible is very important. Therefore, from the charging to melting material etc. it should be in strict accordance with the operating rules, so as to avoid premature damage and cause some accidents.

After each smelting, we must observe the crucible, if the damage is found in the tungsten crucible, it should be timely repaired. It can adapt the hot patching or cold patching when repair it. The size ratio of repaired materials and lining materials should be consistent in the selection. The use of boric acid dosage can be slightly higher. Under special circumstances, it can be added a small amount of water or water glass. For the serious damaged crucible, after cooling, the surface layer of crucible can be stripped with a certain process, and then repair the bottom, scrape the bottom shape of the crucible with the scraper, and finally put it into the sample of the tungsten crucible to repair the wall of tungsten crucible.

The above is the maintenance of tungsten crucible and molybdenum crucible, we hope that can help you in the production and use.
