General Information of Low Porosity Fireclay Brick SG12

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.

Q:How to choose the proper refractory bricks when buying the refractory bricks?
Crack condition. 4. 6. Inspection of dimensions. Conditions of pits and swells and lack of edges or angles. The inspection of refractory bricks' appearance quality and the condition of the affecting with damp.
Q:What are the factors that determine the weight of the refractory bricks?
(5) Under high temperature, the volume is stable, the inner part of brick will produce unrecoverable volume shrinkage or expansion because of the internal transformation. Therefore, masonry inner will produce stress to make the material break and peel off, and the weight of a ton of bricks is determined by the bulk density and quantity, how much is the weight of refractory bricks, refractory bricks should have the ability to resist the damage, the weight of a piece of brick is determined by the bulk density: Refractory bricks are used under high temperature for a long term: Refractory bricks in the use of the process. Cooltech refractory brick used in various high-temperature equipment: The temperature of some parts of metallurgical furnace and other industrial furnace is uneven due to rapid temperature change during operation. (3) good thermal stability: Refractory bricks should not only have a high fusion temperature, no softening deformation and collapse, causing damage to the masonry. (4) strong resistance to slag: Modern metallurgy and the other industrial furnace heating temperature is generally between l000~1800. Refractory bricks should have the performance that is not easy to melt under high temperature. Therefore. Therefore, it is subject to high temperature conditions of physical and chemical corrosion and mechanical damage, the refractory brick must have the ability to resist high temperature chemical corrosion, the volume of refractory brick is required to be stable under high temperature. (2) High-temperature structural strength, chemical corrosion of metal, but also should have been built in the stove brickwork load or other mechanical vibration, often has the high temperature slag, so the refractory materials performance should meet the following requirements: (1) high refractoriness
Q:Mainly use the raw materials inside refractory bricks,
Go to the refractory factory to buy some refractory mortar that has the same texture of refractory bricks, the general boiler use clay refractory mortar.
Q:Can refractory bricks be used to build a house?
Refractory brick can be used to build houses, but you can not use ordinary cement to build, the cost is 3 times than that of ordinary brick.
Q:How much refractory material is required for 1 million tons of coke oven
This depends on the number of specific cubic, different factory designs different boiler, we need volume to caculate.
Q:How to increase the service life of high temperature refractory bricks?
The wedge brick should contain the brick surface distortion, decrease scrap rate high temperature refractory brick is refractory with a certain shape and size, the error of symmetry and concentric reducer's size differences. The correctness of shape of the straight refractory brick should include the straight of the intersection and the distortion of brick's face. Under the premise of ensuring the service life, the key to improve the efficiency of manufacturers, and have the correct shape and precise size. This is to ensure that the product is qualified, refractory brick in addition to planning a reasonable scale, that is, the scale of the allowable error.
Q:do the used refractory bricks pollute the environment?
the main pollution of refractory brick is coal gas pollution in the process of burning , it can be recycled to produce aggregate, waste brick has no pollution.
Q:The form of boiler furnace wall
Q:1200 degrees inside the furnace, lay a layer of refractory brick, what is the temperature outside?
except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
Q:how to distinguish the quality of high alumina refractory brick when you buy it ?
see the gap between the bricks and between kiln roof and kiln wall, etc.. 6, the pressure and the volume density of Pei brick and brick Pei size, appropreate matching of high alumina powder and high aluminous aggregate and other materials, the drying and time, and the mud trapped material humidity 1. 7, to reach the requirements of production. 4, the order of loading Pei brick into kiln . should prevent the lack of a scene , the requirement , mixing time, different procedure and the order of the adding of raw materials of high alumina brick. 3, drawing plan and lack of edge of high alumina brick . 5
