FIRE CLAY BRICK

CMAX fireclay bricks are made from clinker clay. The alumina content ranges from 36% to 48%.

Application
CMAX fireclay bricks are commonly applied in blast furnace, hot blast furnace, teeming ladle, glass furnace, etc.

Features
◆Low thermal conductivity ◆High refractoriness

◆High mechanical strength ◆Excellent thermal shock resistance

Fireclay Brick with Al2O3 Content around 30%

Q: Can refractory bricks be used when it cracks for 1cm: 3, If the crack is caused by burning or drying, then it can't be used. While if the carck is caused by refractory brick molding, it still can be used. 4, the crack is caused by refractory bricks raw materials.

Q: How to distinguish between sintered clay brick and sintered coal gangue brick: Sintered coal gangue brick with coal gangue as main raw material, sintering after selection, crushing, molding, drying and baking into non clay brick. The raw materials division, brick making raw materials for all coal gangue, coal gangue brick is full. But some coal gangue by plasticity index, sintering properties and harmful chemical composition and other reasons, not the whole production of coal gangue brick, in general to be adding a small amount of clay, shale or fly ash brick by improve the performance of raw materials, production from coal gangue and clay, coal gangue and fly ash or coal gangue and shale as raw material the coal gangue brick.

Q: is it good to use firebricks to preserve the heat of rto furnace? Is there any other good ideas?: Operating noise is very low, having a very strong chemical stability: The thermal conductivity is lower than 0 at normal temperature, it not only reduced the cost of the project of RTO furnace, but keeps the indoor heat dissipation heat better and reduce noise pollution. the temperature of RTO furnace surface is low after using the ceramic fiber lining to keep the heat, thereby reducing the addition of auxiliary fuel : ceramic fiber has a good thermal shock resistance: The dosage form of HLGX-589 and HLGX-312 ceramic fiber material is shown in figure RTO furnace thermal insulation material. C, good thermal shock resistance, without reserving expansion joints, ensure the lining intact, not easy to be affected by the harsh combustion atmosphere inside the RTO furnace, can deal with the temperature changes caused by periodic replacement of RTO furnace inlet. The furnace is new energy-saving furnace developped recent 30years that used for eliminating harmful exhaust gas caused by steel or paint spraying. it has long service life, high chemical stability, no heat preservation precedent for refractory bricks; B, good heat insulation effect.

Q: Expansion ratio of light corundum fireproofing brick: And then the appropriate drying, the using temperature 1500~1700 degrees of light corundum brick, the porosity is 70% to 80% Now, use foaming method to produce light corundum brick, 3g&#47, shaped idiosome with mould dry for 4 days in 60 degree to 70 degree oast, it will demoulding, foaming method and evaporating method produce light corundum brick, the thermal conductivity is 0. the containing of AL203 has difference, the corundum brick that use corundum hollow?sphere to produce contain the highest AL203 Finished light corundum brick don't have accurate shape and size after firing.8 1, so products need mechanical or manual cutting after the kiln, finally, firing in 1300 degree and 1550 degree, basically still meters with water forming, just add to burn: 50~60h, because its production methods and the introduction of additives are different, the total sintering time.17W&#47, light corundum fireproofing brick can be made into density is 0, withstand voltage strength is 4MPa, the containing of A1203 is no more than 99%.

Q: Will the heat be taken away by the refractory brick: The heat will be taken away by the refractory bricks.

Q: Are buildings allowed to use red bricks?: Is the red brick with clay, shale, coal gangue as raw materials, crushing, mixing kneading with artificial or mechanical pressing, sintering and building bricks after drying at 900 centigrade temperature by oxidizing flame firing, invented by the babylonians.

Q: What are the properties of clay bricks?: The clay brick refractoriness in above 1600 degrees, but the beginning of softening temperature is very low, as long as 1250 to 1300 DEG C, and softening start temperature and end temperature (fflJ40% deformation temperature) of large distance, this distance is about 200 ~ 250 DEG C.

Q: What kinds of annealing furnace refractory bricks there are?: But the energy saving effect is good, but also can use lightwight heat insulating brick, but the price is higher than that of clay brick

Q: what is the ratio of refractory mortar and refractory bricks, such as how much refractory mortar is needed for a ton of refractory bricks?: Go to the refractory factory to buy some refractory clay that is of the same material as refractory bricks, generally boiler uses clay refractory mortar.
