Fireclay Brick Light Weight Insulating Fire Brick

Q: What is the standard size of high alumina brick?: The country has laid down a number of criteria for the use of refractory bricks to unify market demand.

Q: What is the price of the first grade high alumina brick?: Many factories in Xinmi have high alumina bricks, but they must choose a regular factory. Kuwait refractory level high aluminum brick price at around 1600, the quality of double stable supply

Q: Density of high alumina bricks: High alumina brick by aluminum content is divided into four grades, three grade high alumina bricks content of not less than fifty-five percent, two grade high alumina bricks content of not less than 65, a high aluminum brick content of not less than 75, super high aluminium brick content above 85. As for the high aluminum brick shape, in addition to the standard high alumina brick, high alumina brick and general type, also called special high alumina brick, if the shape is very irregular it is usually called the specific type of high alumina brick, in short, to customized according to the specific use of kiln.

Q: The cloth blowing is not uniform on the lime kiln refractory brick is damaged it: People with the shaft kiln cement clinker kiln, because of small size, low calcination temperature, using only Al2O3 containing a single clay brick is 30 ~ 40%, the rotary kiln was improved in the early Yuan faith this experience, use of high alumina brick and clay brick, from 60s onwards, due to large scale kiln and to strengthen the operation of the high temperature parts of kiln lining, alkaline brick masonry is widely used, the main varieties are: magnesia chrome brick, magnesia spinel brick and dolomite brick.

Q: What are the high temperature refractory mortars made of?: Products used in metallurgy, building materials, machinery, chemical, power industry, industrial thermal furnace, for masonryBuilding clay brick, high alumina brick and corundum brick have the characteristics of full grey seam, good airtightness, high bonding strength, high temperature performance and suitable construction time

Q: What is spalling resistant high alumina brick?: Using bauxite as main raw materials, the introduction of a small amount of ZrO2 (ZrO2 is due to phase transition, between monoclinic and tetragonal type can improve the thermal stability of the products), adding a certain amount of binder and additives, the particle size distribution control mud, forming and sintering of refractory products produced, called anti stripping high alumina brick.

Q: The difference between light high alumina brick and heavy aluminum brick: Lightweight high alumina brick, also called high alumina insulation brick. Alumina content of 48% or more, mainly from mullite and glass phase or corundum composition of lightweight refractory. Volume density 0.4 - 1.35g/cm3. Porosity 66% - 73%, compressive strength 1 - 8MPa. Better thermal shock resistance. Usually, a high alumina clinker is added with a small amount of clay. After grinding, it is poured and shaped in the form of slurry by gas generation or foam method, and it is fired at 1300 - 1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.

Q: Does the chimney have high acid resistance?: The chimney particles and gases, mostly coal tar products, material acidic, therefore, take good acid resistance, acid proof brick, Grouts also used potassium silicate clay acid is preferred.

Q: What are the lining structures of lime rotary kilns and what are the requirements for refractories?: The current configuration of domestic calcining active lime rotary kiln refractories are as follows: the discharge end of low cement high alumina castable with 3% steel fiber; the cooling zone and the firing zone: dry magnesia spinel brick with high aluminum brick with high temperature; preheating: high alumina brick; low temperature preheating zone: clay brick light clay brick; feeding end: low cement high alumina castable with 3% steel fiber; in addition, brick size also have the corresponding requirements; dimensional tolerances: dimensional tolerances used in different parts of the requirements are not the same, the general control in 2mm; corner damage: general permit edge damage 40mm and 5mm deep within angle loss in the hot and cold surface is allowed to have only one, three edges and the length of not more than 50mm; there are cracks parallel to the use of surface crack is not allowed, cracks of brick surface are allowed.

Q: What should be used as binder for making high alumina bricks?: Bond for making high alumina brick: soft clay has good plasticity, so the high alumina brick is usually made of soft clay as bond. However, the free Al2O3 free SiO2 and bauxite clinker clay in under 1200 degrees occurred two times of Mullization reaction, generate large volume expansion, silicon porosity, strength reduction. Therefore, the amount of clay powder in the ingredient should be no more than 5%.
