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

Q: what is consequence of high load and soft low of high alumina refractory brick ?
softening, if not up to the design requirements, may cause vicious incident like the collapse of the stove in use. the full name is softening temperature under a fixed load, as the name suggests, it is the softening temperature after adding the load.
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: 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: the refractory brick in glass furnace burner was burning, the bricks on both sides of the fire hole were burning the blocked it, what will cause brick burning?
The firebrick in glass melting furnace is mainly consisted of zircon brick, other ordinary refractory materials can not effectively prevent the erosion of glass solution. Because the glass melting liquid is eutectic mixture compared to the refractory bricks, it penetrates into the refractory brick and reduces its original performance, simply speaking, the glass melting liquid dissolves the refractory bricks as eutectic mixture .
Q: 90 porous brick and ordinary shale brick, clay brick difference
Porous brick is the original clay brick (now don't let in) and shale increased by a certain gap, but it is also the porosity, thickness is 90, not 53 of the original, there are also some differences in the use of solid brick and. Not for underground use.
Q: How to use the firebrick to build crucible furnace? How to calculate its furnace's width and depth?
1, classify according to the smelting method : Open-hearth?furnace steel: Including carbon and low-alloy steel. According to the different lining material, there are acidic and basic open hearth steel two types. Converter steel: Including carbon and low-alloy steel. According to different positions of blowing oxygen, there are bottom blowing, side blowing and BOF steel three types. Electric furnace steel: Mainly alloy steel. According to the different types of electric furnace and electric arc nail fixed Li modified cool boat to raise spending whale steel, induction furnace...
Q: The foundation is made of Mu10, which is new clay brick and M7.5 cement mortar. What does it mean?
When building the foundation, use Mu10 new clay brick and M7.5 cement mortar! This is the construction!
Q: What are the physical and chemical properties of refractory bricks
The thermal shock stability, linear?change?on?reheating, softening temperature under a fixed load, compressive strength under normal strength refractoriness
Q: what type of refractory bricks does TZ-3 stands for ?
Z stands for the straight brick, T stands for general brick. general straight shaped standard brick, -3 is the length, specification is 230*114*65 (mm)
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.
