Low thermal expansion means mullite castable has a low linear change rate. This refractory castable for sale is conducive to keeping the equipment stable. Meanwhile, it reduces the high-temperature damage to industrial equipment. So it can extend the life cycle of furnaces, and reduce the costs of repair. It is usually used for steam boiler and lining of furnaces.
Mullite castable has good chemical stability. It can sustain a stable state when it suffers erosion or shock. The cold compressive strength is 100MPa when it is used in 24 hours and 110℃. Good wear resistance helps the equipment undertake strong abrasion in high-temperature situations. It could used for the vulnerable parts.
Mullite refractory castable can contact flame directly. It has good thermal resistance that can resist the thermal shock. Therefore, it can resist the high temperature and high pressure in service time. The low linear change rate also means it has good thermal resistance as a refractory material. It could used in tubular heating furnaces for the petrochemical industry or other industries.
Mullite based castable is a kind of refractories and monolithics. This material can directly touch the flame as working linings. It is suitable for linings of observation doors, steam boilers, tubular heating furnaces for the petrochemical industry, other industrial furnace doors, and so on.
Mullite-based castable improves the abilities by adding other raw materials.
