Corundum mullite poly light brick is a new type of energy efficient refractory material, can directly contact the flame, with high temperature, high thermal shock stability, high strength, small thermal conductivity and other characteristics. Widely used in ceramic roller kiln, shuttle kiln, cracking furnace, hot stove and a variety of electric furnace lining, door bricks, kiln tiles and so on.
Characteristics
1.Low thermal conductivity, with a good thermal insulation effect
2.Low hot melt, due to low thermal conductivity, mullite series of light insulation brick accumulated little heat, in the intermittent operation of energy-saving effect is obvious
3.High purity,high refractoriness,and the high alumina content make it maintain good performance in a reducing atmosphere.
4.High thermal compressive strength
5. Extend the life of the lining
6.Could make in special shape to reduce the application amount of bricks.

High Alumina Brick, RefractoryHigh Alumina Brick, High Alumina Fire Brick for Blast Furnace

Low creep high alumina brick for blast furnace is made of corundum, mullite "sillimanite, andalusite and kyanite" and high quality bauxite clinker as raw material by shaping at high pressure and sintering at high temperature.
Characteristic:
1.The content of AL2O3 is 48%.
2.High refractoriness. The temperature is up to 1750~1790�ºC, it belongs to High-duty Refractory.
3.High refractoriness under load. The URL is higher than fireclay brick as the high content of Al2O3, however, it is lower than silica brick because of mullite crystal does not form reticular tissue.
4.Excellent slag resistance. High alumina brick is a kind of neutral refractory material so it enjoys excellent resistance to acid slag and alkali slag corrosion.

Application:
The main markets for low creep high alumina brick are building lining of hot-blast stove, blast furnace, coke oven, rotary kilns of cement and so on.
High Alumina Brickis made fromhigh grade bauxite,it has the advantage of high refractoriness under load,long service time,good thermalinsulation performance andso on

Dry anti-penetration castable to extend the life of the cathode liner has a positive effect. On the one hand can buffer the cathode carbon block uplift; the other hand can strengthen the bottom of the security
The ability to reduce the heat loss at the bottom of the tank and to increase the temperature of the cathode carbon block itself and to reduce the temperature gradient between the upper and lower sides of the cathode carbon block. Due to dry
Dry anti-penetration castable can be infiltrated with the electrolyte to produce a layer of 5 to 15 mm thick, dense glass-like kaolin barrier layer:
This barrier, on the one hand, prevents the electrolyte from continuing to penetrate the lower part and protect its lower part
The temperature of dry anti-penetration castable is not destroyed; the other hand, because the barrier layer with plasticity and particle layer has a certain compressibility, can effectively alleviate the furnace uplift,
Deformation of the tank shell and other issues. Therefore, in the aluminum furnace in the furnace process, it can be placed directly on the insulation brick, the compaction of the upper part of the upper directly placed.
