Mullite Refractory Castable Introduction
 
Mullite refractory castable as a kind of hot sales refractory castable for furnace application in Rongsheng factory manufacturing with mainly used as lining for various kiln such as boiler, blast furnace hot blast stove, heating furnace, ceramic kiln. Mullite based refractory castable have good properties of high service temperature & thermal insulation and direct contact with flame . Mullite refractory material has the advantages of high temperature structural strength, low temperature creep rate, low thermal expansion, strong chemical resistance and thermal shock resistance. There are for sale cheap mullite refractory castable in RS fire bricks company can provide castable refractory mullite specification and category as well as competitive price & high grade quality refractory mullite castable, other specification according to customer requirements, welcome to contact us or email us for free quote or price list.
 
Mullite Refractory Castable Definition
 
The mullite refractory castable is made of excellent porous mullite aggregate,refractory castable is stirred with fine powder and additives. The material ratio can be adjusted according to the actual use of the boiler to carry out customized production. The mullite aggregate has a critical particle size of 12 mm and a long term use temperature of 1350 ℃. The mullite refractory castable has high use temperature and can be directly contacted with flame for working lining to achieve high temperature and energy saving, the unit weight is light, the structure weight is reduced by 40-60%, the hidden trouble of the brick hanging brick is eliminated, the porous mullite bone Ingredients, low thermal conductivity, good thermal insulation performance, fast oven drying, shortening furnace life, significant economic benefits.

Mullite Refractory Castable Application
 
1.Castable refractory mullite application in the high temperature parts such as kiln mouth and cooling machine before and after cement kiln.
 
2.Mullite refractory material is mainly used as the lining of various kiln such as boiler, blast furnace hot blast stove, heating furnace and ceramic kiln.
 
3.Mullite refractory castable is suitable for petrochemical industry tubular heating furnace, light diesel oil, ethane cracking furnace lining, atmospheric and vacuum furnace, sulfur recovery unit, steam boiler, tortoise shell insulation layer, two cylinders and pipe insulation Layer, other industrial furnace doors, fire holes, observation hole door lining.
 
Mullite Refractory Castable Advantage
 
1.Castable refractory mullite is a kind of refractory material which does not need to be formed, has good fluidity after being mixed with water and stirred.
 
2.Castable refractory mullite structure is made up of aggregates, powders and glues according to the process ratio. Castable refractory mullite can replace the products with complex shapes, high degree of profile and wide area.
 
3.Castable refractory mullite is easy to use, shorten the construction period and reduce labor and strength and other advantages.
 
4.The mullite refractory castable has good flow properties, peeling resistance and thermal insulation properties, mullite refractory bricks is suitable for application in high temperature parts of the heating furnace. Mullite refractory castable has obvious effect on improving the service life of the furnace body, reducing the thermal conductivity of the heating furnace body and improving the thermal efficiency.
 
Mullite Refractory Castable Manufacturing Process
 
Step 1:The order of feeding of various raw materials is: granular material-fine powder, static mixing for 5~10min, uniform particle size discharge, loading of binder, admixture (water reducing agent, anti-explosive agent) according to the ratio requirement, after accurate weighing.
 
Step 2:Put it in a small plastic bag and put the small plastic bag into a large ton bag.
 
Step 3:In the production process of mullite based refractory castable, corundum granules are used as the main component, mullite powder is a density enhancing powder, which can effectively improve the load, softness, peeling resistance and compressive strength of the products. The softening temperature of the products on the pellet furnace can reach above 1600 °C.
