General Information of Fireclay brick UNF42

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

Our Fireclay bricks are the final result of blending excellent fused alumina and silicon as the main raw materials 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 Fireclay Brick UNF42

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 Fireclay Brick UNF42

Fireclay brick UNF42 is mainly used in the part of throat, stack, hearth, bottom for blast furnace and the stack for a big blast furnace.

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
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&#47, only elementary substance has specific heat refractoriness.
Q: does the furnace wall use refractory bricks to keep the heat? Or use the insulation material to keep heat ?
if use the rock wool or aluminum silicate, the furnace arch and furnace wall of biomass boiler all use refractory brick, and outside the furnace wall there is a layer of insulation material, some is perlite coal-fired boiler
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: Why can't build refractory brick behind the skew block?
Refractory is heat expansion and cold contraction, when it is high temperature, it will squeeze toward the center and the vault will be deformation .
Q: How about clay bricks?
Fired ordinary brick is one of the indispensable building materials in production and life, but its quality is not good or bad in the absence of professional equipment. Now to introduce a little trick:According to the main raw materials for clay brick, shale, coal gangue and fly ash brick. Mainly in our local clay brick. According to the compressive strength of weathering resistance of radioactive material and qualified brick, according to the size deviation, appearance quality, efflorescence and lime burst into superior products, first-class products, qualified three quality grades.
Q: What is the difference between a clay brick and a red brick?
Burning bricks are generally low temperature clay brick, brick, brick high.
Q: How to count the number of loading refractory bricks?
Use one meter by one meter wooden raft-towing: use one meter raft-towing to count: Known your brick is T-3 standard bricks, each four layers lies down 15 and sidewards is 4 =64; according to 3.4kg, 47 clay bricks can hold 10 to 12 layers. According to the upper limit, each raft-towing can hold 2.3 tons
Q: is there any requirement for radioactive materials in refractory materials.
they all do not cause radiological hazards to the environment, so no requirements! analyze rom the element , magnesia. Do not know if it is useful, but material used by refractory materials, firstly any chemical elements are radioactive, human beings can not close, then, such as silicon dioxide: If it is radioactive. analyze from use, such as bauxite, does not have the use value
Q: What is the proportion of lightweight fireclay bricks?
It is a lightweight refractory product containing aluminium 30%-46%. It is made of clay clinker or light clinker as the main raw material. It is usually produced by combustible material. It can also form porous structure by chemical or foam method.
We are an industrial enterprise of refractories integrating the scientific research, design, production and engineering service. With first-class quality of products, high-efficient and prompt after-sale service, our products are not only well sold in many domestic large steel enterprises and coking enterprises, but also widely exported to more than 23 countries and regions.
