General Information of Low Porosity Fireclay Brick SG10

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 SG10

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 SG10

Low Porosity Fireclay Brick SG10 is mainly used in glass furnace.

Q:Characteristics of refractory bricks
The ability to resist rapid changing temperature and not to be destroyed is 6, it refers to the change of the volume expansion and contraction in the same temperature change. the porosity is 3, this parameter is very important in its own properties, anti bending strength, but as a manufacturer, you must strictly control the explicit hole through the material unit area of heat flow rate: The main composition determines the quality and characteristics of the refractory material 2: Unit volume weight, good impact resistance, abrasion resistance show good compactness: Also called high temperature load, it begins to deformation temperature, the volume density, we define such a linear change rate is 0 physical and chemical properties is 1: 5, but the heat conductivity coefficient may be large, load softening temperature, porosity: The ability to withstand shear stress is 8, compressive strength: Did not make specific requirements about thermal shock resistant performance: Resistance to anti penetration erosion under high temperature and not destroyed 7: Don't have to explain it, linear change rate, thermal conductivity, slag resistance: Also known as linear change on reheating or the residual line change, if the expansion and contraction of each time is the same: Under the condition of unit temperature gradient, the service life is 4, chemical composition.
Q:General used refractory brick T-20 / T-39/ T-206 specifications and dimension
No T-206 model (we produce the clay) T-20 and T-39 are the size of 230*length, 113* width and 65/45 thickness, T-20 is a vertical arch brick and T-39 is horizontal arch brick.
Q:what effect does big mortar joints of the boiler refractory brick have on the boiler?
The ventilation leakage。 Now the larger boilers are generally used refractory pouring material one-time pouring, the arch is easy to collapse . 2, shrinkage and expansion of brick will make the bricks fall. 1, do not use the refractory brick. too large seam will effect the tightness of furnace wall , and the water wall is easy to form dew and be corroded and to leak smoke.
Q:does all the refractory refer to refractory bricks when making steel?
deoxidizer belongs to ferrous metallurgy auxiliary; refractory used during steelmaking is not only refractory bricks, but also foaming agent, refractory castable and Ladle filler sand.
Q:What are the differences between diatomite brick and ordinary refractory bricks?
The volume density of diatomite brick is 3.9 * 10-6, good compressive strength, belongs to the small outer insulation, spinel brick.
Q:Can thick steel plate be used instead of the furnace inside the refractory brick?
It depends on the temperature. The steel plate is a kind of heat conduction material which hasn't heat insulation, which should be based on the working environment.
Q:What is the difference between the refractory bricks, hand-made bricks and the machine pressure bricks?
Withstanding voltage strength is not the same, the strength of the mechine-made is higher
Q:can the red brick be used as refractory brick?
Can not replace! The high temperature will make it burst. Coefficient of thermal expansion is not enough
Q:What is the advantage of the ceramic fiber material compared with the refractory brick?
Ceramic fiber material is heavier than refractory bricks, property of machinery operation, low heat capacity, and has high anti-stretchability and good thermal shock resistance, low thermal conductivity make its thermal insulation effect is ten times than refractory brick, it won't has crack in sudden coolness and heat, and the construction is much easier than that of refractory brick, not delaying the production.
Q:What kind of refractory brick is suitable for 24*28m rotary kiln of 5,000 tons?
24~28 meters belongs to the transitional zone, magnesia spinel brick or silicon carbide brick (Series)
