Description of fireclay bricks
CMAX fireclay bricks are made from clinker clay. The alumina content ranges from 36% to 48%.
Features of fireclay bricks
1. Lower content of iron, alkaline and impurities, good high temperature properties.
2. Homogeneous structure, light weight, energy saving because lower heat storage in the furnace during cooling cycles.
3. High strength, good thermal shock resistance under high temperature.
4. Precise sizes due to grinding and shaping after firing, which meets the requirement of construction.
Applications of fireclay bricks
CMAX fireclay bricks are commonly applied in blast furnace, hot blast furnace, teeming ladle, glass furnace, etc.

- Q: does furnace use refractory cement to make refractory bricks?
- use refractory clay, refractory clay is made of refractory clinker clay mixing with cornstarch in a certain proportion, generally refractory cement refers to alumina?cement, which is generally used in castable refractory, producing binder.
- Q: What types of refractory bricks are divided into?
- The flue has fireproofing time requirements, very expensive, I just know this in my project, using a special refractory brick and fireproof plaster
- Q: Clay brick, red brick, always fried brick how to do?
- Red brick fired, try using a bubble, if not burst, you can use.
- Q: Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
- Now all use castable refractory, the outer layer is generally pouring refractory castable, the inside layer is a heat insulation castable refractory.
- Q: What are the simple ways to distinguish between excessive clay bricks and less fired clay bricks?
- Generally speaking, compared with the exterior burning brick, the internal combustion brick not only saves the clay and the waste material, but also has smaller volume density, lower thermal conductivity, and can increase the intensity by about 20%. Burnover light color, sound, low intensity; burned brick deep color, crisp sound, high strength, irregular size. These two kinds of bricks are unqualified products.
- Q: What is the proportion of lightweight fireclay bricks?
- The ingredients are mixed with water to form plastic mud or mud, by extrusion molding or casting molding, after drying at 1250-1350 Deg. C oxidation atmosphere sintering. The volume density of commonly used clay bricks is between 0.75-1.2g/cm3. In reality, the proportion is 1.
- 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: Which is the higher price of concrete solid brick and MU15 fired common brick (non clay brick)?
- The price of concrete solid bricks and the price of MU10 bricks are on the same level, and the difference will not exceed two cents a penny. It should be MU15 sinter ordinary brick is more expensive.
- Q: What is the raw material for the production of refractory bricks?
- Refractory raw material, sodium silicate as a binder, and lightweight aggregate, magnesium sand, magnesia calcium. Magnesium Oxide, bauxite, and then lightly burn: Hard refractory clinker
- Q: Can refractory bricks be used to build a house?
- Refractory brick can be used to build houses, but you can not use ordinary cement to build, the cost is 3 times than that of ordinary brick.
