Mullite castable are easy to use. When water is added to it, the particles in the mullite castable form a uniform slurry with the fine powder. The setting time of this mixture is relatively short. Generally speaking, it only takes about 20 minutes to achieve a good hardening effect. In addition, mullite castable has less cement content and stronger fluidity, making them suitable for various locations.
Mullite castables are used in petrochemical industry tubular heating furnaces, light diesel oil, ethane cracking furnace linings, atmospheric and vacuum furnaces, sulfur recovery devices, steam boilers, tortoise shell mesh insulation layers, two cylinders and pipe insulation units. Floor, other industrial furnace doors, fire holes, observation hole door linings, etc. If you want to communicate more applications of this product, welcome to follow Kerui Facebook page.
