General Information of Fireclay brick

Our corporation producesa comprehensive range of Fireclay bricks, with 30% to 55% alumina content, allof these bricks exhibit excellent performance.

Our Fireclaybricks are the final result of blending excellent fused alumina and silicon asthe main raw materials with cutting-edge technology, adding superfine powder,after mixing, drying, forming, in the high temperature shuttle kiln. We ensureyou that the Fireclay Bricks made by us possess high quality standard and havegone through all the complicated quality control parameters. Their durabilityand strength adds life to the structure and they have the capacity of bearinghigh temperature.

Feature of Fireclay Brick

Resistant tothermal shock, abrasion, chemical attack

High ability foranti-abrasion during work

Low shrinkagedegree under high temperature so as to maintaining integrity of the furnacelining

Low apparentporosity, and low Fe2O3 content to reduce the carbondeposit in the blowhole and avoid the bricks broken in case of expansion

Applications of Fireclay Brick

Fireclay brick is mainlyused in the part of throat, stack, hearth, bottom for blast furnace and thestack for a big blast furnace.

1. Carbon bakedfurnaces in the alumina industry

2. Preheat zonesand cyclones of rotary cement kilns

3. Insulation forglass tanks

4. Coke ovens

5. Blast furnaces

6. Reheatingfurnaces

7. Suspended roofs

8. Lime kilns

9. Chimney

Q:How to classify light refractory bricks?
Continuous casting use silicious insulation board, silica insulating refractory brick, ceramsite lightweight refractory concrete building block and so on. 0g/ clay lightweight heat insulating brick NGO.4-1.5g/, high aluminum lightweight heat insulating brickLGO.4-0.4-1.7G/, resistance furnace Diatomite brick 0; cm3; cm3; cm3, aluminum oxide insulating refractory products
Q:How to prevent the refractory bricks from burning to crack?
There is just allowed a little moisture contained in adobe.
Q:Will the heat be taken away by the refractory brick
No, refractory bricks can't be burnouted
Q:When using high alumina refractory brick, what are the reasons leading to the decline of the performance of high alumina brick?
The excess air coefficient is controlled in 1, in order to prevent producing water cracks in the production of high aluminum refractory brick from, control the water absorption of 2 grade clinker of bauxite with high alumina below 4%-5%. 1-1,the water absorption of the tube mill should also be controlled below 6%, and adjust thermotechnical, making the high alumina refractory brick burning be in the stable weak oxidizing atmosphere. should be 2
Q:What kind of material is good to be laid on the kiln car, refractory brick?
Ceramic fiber blanket
Q:What are the differences between high alumina brick and high alumina refractory brick?
with the increase of the fire temperature and other indicators, Al2O3 content is also improving. the general content of Al2O3 in high alumina brick is more than 60% .
Q:what is consequence of high load and soft low of high alumina refractory brick ?
softening, if not up to the design requirements, may cause vicious incident like the collapse of the stove in use. the full name is softening temperature under a fixed load, as the name suggests, it is the softening temperature after adding the load.
Q:what kind of refractory brick is suitable for 1300 degrees converter?
High alumina bricks of above 3 grade, containing more than 60% aluminum
Q:What is the name of the white clay refractory brick
The name of white clay is kaolin clay
Q:Small size black brick can replace refractory bricks for wood burning fireplace?
No. Because black brick has no fireproof function. The result of using the black brick can only be counterproductive, and which is also a waste of time and fuel.
