Description:
High alumina fireclay Brick for Heating Furnace is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.
This series of High Alumina fireclay Brick for Heating Furnace are made of selected high alumina bauxite, kaolin clay, hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature

- Q:The matching ratio of masonrying refractory bricks cement
- Size of brickwork joint: Vertical and horizontal seam are 2 ~ 3 mm. The ratio of seam mud: Refractory clay mud 100%; per m3 dry, clean industrial water 400 ~ 600t/, no more than 3mm
- 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 are the advantages and disadvantages of clay bricks?
- Disadvantages of clay bricks1., since the majorCompared with other masonry materials, the weight of the clay brick is relatively large, so the structure needs to bear heavy deadweight, and the cost of the building increases. 2., poor sound insulation effectSound travels to the clay brick, because of its low porosity, without isolation of sound, sound decibel little drop, while other building materials such as now used more concrete block filling the void ratio is large, sound insulation effect is obvious.3, environmental destructionBecause clay bricks are mainly sintered by excavation soil, soil erosion and damage to vegetation have resulted in soil erosion and serious damage to the environment. Therefore, the country is gradually stopping the project to use clay bricks.
- Q:Can lime rotary kiln refractory brick kiln be hung with klin coating?
- Should prevent the rotary kiln from being damaged; why hang kiln coating on the rotary kiln; try to avoid the big knot; 5; maintain the integrity of flame shape; burn top fire; should be hung; to prolong the service life of the refractory brick; steel plate is unable to withstand the high temperature, strengthen calcination control; adjust the high temperature region; let the big block out in time; avoid burning the fire. . Preparation equipment manufacturers 4, find the correct operating parameters of rotary kiln according to the experience; often keep the temperature above 1450 DEG C in the container; what is the reason for the rotary kiln coating; and add a layer of strong protective layer on the surface; the cylinder of the rotary kiln cylinder is made of steel plate; this is only the first step to determine the safe operation of the rotary kiln; avoid damage or smash the rotary kiln coating. 2; measures should be taken to prevent the kiln coating fall off because of the stop of the kiln and the changing of sudden hotness and sudden cold; burn the top fire; raw materials of appropriate preparation ingredients . We need to know the the rotary kiln, make up in time. The fire resistance and thickness of refractory bricks are limited. 6; in the inside of the building with a layer of refractory brick. 8. Observe and adjust frequently; and can reduce the heat loss outward; control the fire; we take 8 steps to perfectly protect the rotary kiln: how to protect the kiln skin that is hung well; improve coal mouth structure; important operation method of long-term effective rate of safety energy-saving ball mill the work will be interrupted; deterioration, strengthen equipment maintenance of retary kiln, after hanging the rotary kiln skin; ensure clinker grain is fine and uniform; improve the thermal efficiency for the benefit of kiln skin sticking, must treat in time ;
- Q:What are the main raw materials of refractory brick and runner brick?
- Types of refractory bricks are divided into low-grade and high-grade. generally, siliceous, semi siliceous and high aluminous runner brick brick have higher requirements. If it needs to contact melting in high temperature molten steel directly, then it is high alumina(the main raw material is clinker of bauxite with high alumina, corundum( brown corundum and white corundum), the refractoriness is high, lower than 1580 DEG C temperature, but the actual using temperature reaches 1630 DEG C
- Q:What's the reason of cracks in refractory bricks?
- The relative density is high, and high temperature heat treatment and increase the strength of qualitative brick, for 10 days, then only the shorter time for heating and drying and dehydrating, you can smash a brick if it's a long time! There will be a stress loose phenomenon making bricks now, the internal density of these crack bricks are not the same, in addition to the effective drying, dehydrating and heating treatment, the time distance is small, basic bricks and finished bricks adopt line production, when drying, the water is also evaporated at the same time, the central density should be high ! The reason is very simple, the greater extrusion force the brick bears in the molding, the closer to the edge, the smaller density is, the better to keep forming, the shorter residence time, the higher the rate of finished product is, which belongs to the natural drying, this phenomenon is more obvious
- Q:What types of building blocks do you have?
- The commonly used shapes are mainly divided into hollow bricks and perforated bricks. In particular to the green landscape construction, decoration materials, building construction, there are many such as: ordinary brick, lime sand brick, sintered shale brick, porous ceramsite concrete permeable brick, lawn brick, pervious brick, hollow glass brick, ceramic tile ground, refractory clay, concrete block wall, floor tiles, solar LED lamp, floor tile dry spray the rubber brick, grass planting brick, brick, split brick, road brick.
- Q:Can refractory bricks be used to pave roads or build a wall?
- Complete refractory brick has standard size and it is heavier than ordinary red brick. the volume ratio is shrinking with change of temperature to crack and strength of brick with brick walls down enough for new
- Q:When the coal-fired steam boiler is built, it is necessary to build a common red brick between the refractory bricks. May I ask what is the requirement for this common red brick?
- unnecessary
