Product Description:

FUSED CAST BRICK

 

CMAX Bricks made from high quality quartz tail sand, lime and mineralizing agent through the process of crashing, screening, mixing, pressing, drying and sintering.

 

Application


CMAX Silica bricks are commonly applied in coke oven, hot blast stoves, glass furnace etc.

 

Advantage

 

Fused cast AZS (alumina, zirconia and silica) firebricks are mainly categorized into 33#, 36# and 41# according to different zirconia's contents from 33% to 41%.
Fused cast alumina (α-β Al2O3 and β Al2O3) firebricks are composed of alpha alumina, beta alumina and small amount of glass phase.

Both AZS and alumina firebricks have shown excellent performance in glass furnace construction.

Q:What are the differences between thermal insulation bricks and refractory bricks?
Thermal insulation brick has low fire resistance, generally is porous and light.
Q:What are the factors that determine the weight of the refractory bricks?
(5) Under high temperature, the volume is stable, the inner part of brick will produce unrecoverable volume shrinkage or expansion because of the internal transformation. Therefore, masonry inner will produce stress to make the material break and peel off, and the weight of a ton of bricks is determined by the bulk density and quantity, how much is the weight of refractory bricks, refractory bricks should have the ability to resist the damage, the weight of a piece of brick is determined by the bulk density: Refractory bricks are used under high temperature for a long term: Refractory bricks in the use of the process. Cooltech refractory brick used in various high-temperature equipment: The temperature of some parts of metallurgical furnace and other industrial furnace is uneven due to rapid temperature change during operation. (3) good thermal stability: Refractory bricks should not only have a high fusion temperature, no softening deformation and collapse, causing damage to the masonry. (4) strong resistance to slag: Modern metallurgy and the other industrial furnace heating temperature is generally between l000~1800. Refractory bricks should have the performance that is not easy to melt under high temperature. Therefore. Therefore, it is subject to high temperature conditions of physical and chemical corrosion and mechanical damage, the refractory brick must have the ability to resist high temperature chemical corrosion, the volume of refractory brick is required to be stable under high temperature. (2) High-temperature structural strength, chemical corrosion of metal, but also should have been built in the stove brickwork load or other mechanical vibration, often has the high temperature slag, so the refractory materials performance should meet the following requirements: (1) high refractoriness
Q:is it correct that the higher the refractoriness is, the better refractory bricks are?
Not completely correct. Refractory bricks need to be strong in addition to the fire resistance.
Q:How to test the various components of the refractory brick?
It is difficult to distinguish if it is mixed together, fully smashing and mixing. Then assay. Or testing after smashing and separating.
Q:The difference between fireclay brick and refractory cilica brick in the application.
Good thermal shock stability, long-term use temperature is not higher than 1300 degrees, high temperature, high strength, low price of clay brick characteristics, thermal shock stability is the worst, a scrap, can be long-term used under the condition of high temperature (exceed 1400 degrees Celsius) . The temperature of silica brick's soft bearing is close to the melting point. Other industries basically don't use, but the comprehensive performance of high temperature is not good, widely used in low temperature parts of a variety of furnaces. The silica brick is generally used in the coke oven and glass kiln, but anti alkali erosion ability is poor
Q:is it good to use firebricks to preserve the heat of rto furnace? Is there any other good ideas?
1. what variety and grade of refractory materials should be chosen to build all parts of the industrial furnace?; 2. is the origin of these materials be assured? mesothern resistance furnace, lightweight refractory brick, refractory fiber, bead brick of 1000 degrees; fuel heating furnace, refractory clay brick, high alumina brick, silica brick, carborundum brick, refractory castable, the plastic refractory of 1300 degrees; heat treatment furnace, refractory clay brick, refractory fiber of 1100 degrees; high temperature salt bath furnace, refractory clay brick, high alumina brick, zircon brick, refractory castable of 1300 degrees; high temperature resistance furnace, lightweight refractory brick, high aluminum bricks, lightweight alumina brick, lightweight refractory clay brick of 1400 degrees; molybdenum wire furnace, alumina brick, corundum brick, carborundum brick, finished alumina hollow ball product of 1650 degrees; cupola, refractory clay brick, carborundum brick, dolomite Brick, carbon brick, graphite brick of 1650 degrees; arc furnac, high alumina brick, silica brick, magnesia brick, magnesia brick, magnesia chrome... Corundum brick, carbon brick, magnesia chrome brick, magnesia brick, high aluminum brick, silica brick, finished alumina hollow ball product of 1700 degrees; cupola, refractory clay brick of 1650 degrees;
Q:How to prevent the refractory bricks from burning to crack?
There is just allowed a little moisture contained in adobe.
Q:How to adjust the temperature in the 160 meter tunnel kiln?
Tunnel kiln can be attemperated by burning products, this will not affect the firing of different products, and can burn back processing products.
Q:What are the physical and chemical properties of refractory bricks
The thermal shock stability, linear change on reheating, softening temperature under a fixed load, compressive strength under normal strength refractoriness
Q:What are the differences between fireclay brick and high alumina refractory brick?
One is the high alumina, solid and hollow respectively, fused mullite as main raw material made of high-grade refractory materials, strong corrosion resistance, has the advantages of through mud treatment, good thermal shock stability. Good resistance to slag, used to build steel making furnace and glass furnace. High alumina brick is a kind of refractory material. Clay brick is also known as sintered brick, electric smelting corundum and low creep high alumina brick [1] with high grade bauxite, this kind of refractory brick's main component is AL2O3, which is suitable for large and small buildings with artificial bulk. High thermal stability. A neutral refractory material with more than 48% of alumina oxide content, clay brick has clay (including shale, molding, coal gangue and other powder) as the main raw materials, cement rotary furnace lining. The product has a small high-temperature creep, one is clay. From bauxite or other high content of aluminium oxide raw materials' forming and firing, refractoriness is above 1770 deg. High R.U.L and medium-sized hot-blast furnace is different firstly in the material, forming from drying and roasting
