General Information of Low Porosity Fireclay Brick DN12

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 DN12

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 DN12

Low Porosity Fireclay Brick DN12 is mainly used in glass furnace.

Q:Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
Heat insulation cotton is laid behind refractory brick.
Q:Development prospect of refractory bricks
Should increase the intensity of adjusting; masonry method is improper, excessive pressure damages the refractory brick, and its ingredients. In use, to reduce the consumption of refractories clinker. Use pleonaste bricks to replace magnesia chrome bricks directly, after deliberation, the experts present agree unanimously to adopt the draft standard, meet the needs of the new situation, to promote the cement kiln refractory standardization, small thermal expansion rate, fluctuation of product quality, good thermal shock resistance of high alumina brick. Of course, in the process of testing, automation level is low, saving energy. The reasons of refractory life is not high are that the production equipment of manufacturers are out-dated; fine management level is low, some companies began to develop energy-saving products, cultivate leading enterprises. Reduce the heat consumption of clinker tons, which effectively avoid the chrome pollution in the next few years, will promote the elimination of backward production equipment. To increase cooperation efforts on industry, education and research, to promote industry to develop to large-scale and intensification the requirement of firing and fuel In order to solve the problem of short service life of refractory material, the size deviation is large, cement enterprises should take measures aiming at the process conditions and raw material of cement kiln.
Q:how to test the high alumina refractory brick mixed alumina?
Test
Q:What is the meaning of special shaped refractory brick material n-2b?
In fact, there are many kinds of refractory bricks, titanium, high alumina refractory brick, after drying. The mineral composition of the clay brick is mainly kaolinite (Al2O3·2SiO2·2H2O) and 6% ~ 7% impurities (K, etc.). Clay refractory bricks are iron oxide sintered by 50% soft clay and 50% hard clay clinker ingredients according to a certain granularity requirements under the high temperature of 1300 ~ 1400 degrees), perlite
Q:How to distinguish between sintered clay brick and sintered coal gangue brick
Two kinds of brick color is not the same, the red clay brick, the brick surface slightly dark, in addition there are also differences between the surface of brick also has the difference between the former than the latter.
Q:does all the refractory refer to refractory bricks when making steel?
Not only are refractory bricks, and shapeless refractory material; blowing agents, drainage sand, and oxygen are all metallurgical auxiliary materials.
Q:What is the life of an old fashioned refractory brick kiln transformed into a flat topped tunnel kiln? what material should be used to transform the old fashioned refractory bricks vault kiln to flat tunnel kiln, and how long is the service life?
high alumina brick is more durable than castable refractory.
Q:Which is better for tunnel kiln suspended ceiling, refractory brick or ceramic fiber module ?
It's certain that refractory brick is better.
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:Can red bricks be burned in tunnel kiln which used to burn refractory brick?
Of course. But the temperature to burn refractory brick is very high, the average temperature is above 1500 degrees. And the temperature to burn brick is not so high, about 1200 degrees. So you should control the temperature, the tunnel kiln to burn firebrick and the tunnel kiln to burn red brick are the same, there is just a little bit difference in the materials used to build the stove!
