General Information of Low Porosity Fireclay Brick DN10

Our corporation produces a comprehensive range of Low Porosity Fireclay bricks, with 30% to 55% alumina content, all of these bricks exhibit excellent performance.

Our Low Porosity Fireclay bricks are the final result of blending excellent calcined flint clay and calcined bauxite, with cutting-edge technology, adding superfine powder, after mixing, drying, forming, in the high temperature shuttle kiln. We ensure you that the Fireclay Bricks made by us possess high quality standard and have gone through all the complicated quality control parameters. Their durability and strength adds life to the structure and they have the capacity of bearing high temperature.

Feature of Low Porosity Fireclay Brick DN10

Resistant to thermal shock, abrasion, chemical attack

High ability for anti-abrasion during work

Low shrinkage degree under high temperature so as to maintaining integrity of the furnace lining

Low apparent porosity, and low Fe2O3 content to reduce the carbon deposit in the blowhole and avoid the bricks broken in case of expansion

 

Applications of Low Porosity Fireclay Brick DN10

Low Porosity Fireclay Brick DN10 is mainly used in glass furnace.

Q:What is the perservation method for refractory bricks used for cement kiln?
The place should be dry and ventilated. Remember that the packaging can't be damaged. If is not used for a long time, put desiccant next to the bricks. Then have thermoplastic packaging again, it won't get damp. Under normal circumstances, it can be stored for 3-5 years and won't be hairy
Q:Is the thickness of the kiln lining and the refractory brick the same concept?
This is certainly not the same. The thickness of the refractory brick can be arbitrary, the thickness of the kiln lining is generally designed according to requirement
Q:What is the specific heat of a refractory bricks (clay)?
Approximately it's about 2000; M3 specific heat is wrong with this argument, two degree clay is 1730 degrees, three degree clay is 1690 degrees, clay bricks are mixture, bulk density, 1900KG/, only elementary substance has specific heat refractoriness.
Q:What are the main constituents in non clay brick sintering?
Sintered clay brick, it is through the mining soil, brick making, modulation, drying, roasting and cooling produced, roasting coal amount is solid sintered clay brick coal blending amount of 20-60%, the amount of coal to ensure product's surface.
Q:is refractory brick used around the mechanism flue?
Q:What are the weak points of clay bricks?
SiO2 and Al2O3 in clay bricks form eutectic, low melting point silicates with impurities during sintering, and are surrounded by mullite crystals. Clay brick belongs to weak acid refractory products, it can resist acid slag and acid gas corrosion, and its resistance to alkaline material is a little worse. The thermal performance of clay brick is good, it is fast and cold. The clay brick refractory brick and be roughly the same, up to 1690~1730 DEG C, but the load softening temperature is 200 degrees Celsius above the low brick. Because clay bricks contain crystalline Mullite with high refractoriness, they contain nearly half of the amorphous glass phase of low melting point.
Q:how to test the high alumina refractory brick mixed alumina?
The first thing before producing bricks is to test whether the aluminum content reaches the standards, general testing on raw materials. Second: the shaped high aluminum brick will be tested in some professional equipment, you can know it from the professional inspection departments.
Q:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of brick has the highest refractory temperature?
It depends. if high alumina brick is used in kiln, its temperature is above 1700 degree, clay brick is between 1500 degree to 1750 degree, magnesia bricks and magnesia-chrome bricks are about 1500 degree to 1650 degree.
Q:What is the size of mechanism brick and general refractory brick?
The ordinary refractory brick is 230mm long, 53mm thick; red brick is 240mm long, 115mm wide, 65mm thick,
Q:Solid brick and clay brick which is expensive
Because the sintered clay brick belongs to the material which destroys the cultivated land, the national policy restricts the use and is forbidden to use the standard brick. But it can be used in the base part.
