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.

Fireclay Brick UNF42

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.

1. Carbon baked furnaces in the alumina industry

2. Preheat zones and cyclones of rotary cement kilns

3. Insulation for glass tanks

4. Coke ovens

5. Blast furnaces

6. Reheating furnaces

7. Suspended roofs

Q:How to repair the boiler?: What kind of boiler, the external wall or the furnace arch, the smoke wall, the material: High-alumina cement, refractory brick, refractory clay, knife brick

Q:What is the refractory brick in silicious model?: Adding appropriate amount of mineralized agent to promote the transformation of quartz in the body into phosphorus quartz. Smaller coefficient of thermal expansion. Also used in high temperature bearing part of hot blast stove and acid open hearth furnace, refractory materials and ceramic kiln, kiln vault and other load-bearing parts, thermal shock resistance variation. High temperature strength. the glass furnace is burnt in 1430 to 1350 degrees Celsius in the reducing atmosphere. use natural silica as raw materials. True density 2. more than 93% of silica content. generally there is no crystal type transformation above 600 degrees celsius. With acid slag erosion and sediment chamber regenerator performance, soaking furnace, open hearth furnace. there is more crystal type transformation below 600 degrees celsius. mainly used in coking chamer of coke oven and partition of firebox. acid refractory material made of high thermal shock resistance, large volume change, square quartz and a small amount of residual quartz and glass box . Long term use at high temperature without deformation

Q:The making process of clay brick: Artificial small bulk for building. Also called sintered brick. Clay to clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting and. Chinese in the spring and Autumn period has created a square and brick, Qin and Han Dynasties brick technology and production scale, quality and variety have significant development, known as "Qin Zhuanhan tile"

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:What are the advantages and disadvantages of clay bricks?: Advantages of clay bricks1. clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete.2. waste bricks can also be used as aggregate for concrete.3. fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.

Q:Can refractory be used to sharpen knife?: Many factories build a smelting furnace by using this kind of bricks. A special knife grinder can be used to sharpen knife, can on 1. They are sizing and non-sizing refractory bricks respectively. Refractory brick is now a lot of fields and industry will introduce one of the raw materials. Products are divided into two different types, refractory brick as a high temperature resistance of the raw materials. In simple terms, working temperature is 770 DEG C, 580 C and 1, of course, refractory bricks also can be used to sharpen knife, use smooth brick to sharpen, need to choose high hardness

Q:What is the density of the high alumina refractory brick?: it depends on the aluminum content, the higher it contains, the larger the density is. the hjghest is 3, the lowest is 2.

Q:High alumina refractory bricks (Universal arc) weight for hot metal ladle: Climbing, C23B ladle generally use T3 ladle bottom brick, brick wall with C23 package, C231 Some permanent layers are built from high alumina bricks, and some are built from castable refractory, T82, T43. Specific size can be checked according to the type of brick

Q:how heavy are boiler of six tons plus refractory bricks?: The total weight is about 60 tons, 6 tons of bulk boiler steel, insulation materials, sealing materials, refractory material

Q:What are the reasons for the production of waste in the formation of fireclay bricks?: The reasons for the production of waste when form fireclay bricks: Tile size is unqualified. This is due to the mold installation is not firm, the template transfers when molding; if the amount of material being added fluctuates largely, also can cause the body size changing. Ji Yangon Chi lie charge generation layer containing decyl poke pull and crack. The molding operation does not according to the principle of the light first and the thick later. At the initial pressure, the air doesn't releases, which causes the elastic aftereffect by repressing. Too much mud water, uneven mixture and inequal template all can make the body produce layer crack or crack. Twist. The template is used for too long, the template deforms, so raw brick deforms, the amount of water is too large, brick naturally deforms, causing the body twist. Miss edge and angle. Because of poor plasticity of mud, particles segregate, feeding back corner is not real, the body will appear side missing and angle modulation phenomenon. Bias voltage. Due to the deflection of the die head or the uneveness of mold bottom. Loose。 Due to insufficient feeding amount or insufficient pressure times.

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.
