High Alumina Refractory Castable Definition
High alumina refractory castable is used as an aggregate and a powder, a refractory castable made of a binder is added. High alumina refractory castable has high mechanical strength and good resistance to thermal shock and abrasion. High alumina refractory castable is mainly used as the lining of various kiln such as boiler, blast furnace hot blast stove, heating furnace and ceramic kiln. Soaking furnace, heat treatment furnace, rotary kiln; various high temperature burner lining, heating furnace water pipe lining, molten steel furnace refining device parts and high temperature wear resistant body of petrochemical catalytic cracking reactor; blast furnace tapping groove, iron The furnace iron tapping tank and the integral spray gun for hot metal pretreatment are lined up. Large prefabricated blocks and linings can be made.

High Alumina Refractory Application
1. High alumina refractory castable can be used as lining for various heat treatment furnace linings and burners, blast furnace hot blast stoves, heating furnaces, electric furnace tapping tanks, lime shaft kiln high temperature section, rotary kiln kiln head, power plant boilers and other industrial furnaces.
2. High alumina refractory castable is mainly used as the lining of various kiln such as boiler, blast furnace hot blast stove, heating furnace and ceramic kiln. Soaking furnace, heat treatment furnace, rotary kiln; various high temperature burner lining, heating furnace water pipe lining, molten steel furnace refining device parts and high temperature wear resistant body of petrochemical catalytic cracking reactor; blast furnace tapping groove, iron The furnace iron tapping tank and the integral spray gun for hot metal pretreatment are lined up. Large prefabricated blocks and linings can be made.
High Aluminum Refractory Castable Production Process
1. According to the formula, the raw materials of high alumina castables are produced.
2. Calculate the amount of aggregate, powder gradation, binder and additive according to the raw material formula, and strictly control the aggregate powder particles.
3. Put the weighed aggregate and powder into the mixer and stir them evenly, then pour the powder into the aggregate and stir for 8-10 minutes.
4. The high aluminum refractory castables that have been stirred are placed in a ton of bags, equipped with additives and binders, and then packaged.
5. The packaged high aluminum castables are stored in the warehouse, the date identification and moisture-proof waterproof treatment are done.
High Aluminum Refractory Castable Use Precautions
1. When making high alumina refractory castable mud, fully stir the dry material and add water. Strictly control the amount of water used to avoid affecting the effect after pouring.
2. When making high alumina mud, it needs to be stirred by a mixer, and manual mixing is prohibited.
3. According to the required amount of production, the production of castables need to be used within 30 minutes, if there is condensation, can not be used.
4. When constructing, pay attention to avoid the anchor parts.
5. According to the design to determine the thickness of the refractory high alumina castable
, can not be cast freely.
6.After pouring and baking, pay attention to the heating rate and time, and not heat up too quickly.
6. After demoulding, check the refractory high alumina castable body. If there is a construction problem, rework according to the situation to ensure the practicability of the casting body.
