General Information of Fireclay brick FC55

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 FC55

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 FC55

Applications of Fireclay Brick FC55

Fireclay brick FC55 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

8. Lime kilns

9. Chimney

Q: does furnace use refractory cement to make refractory bricks?: consistence Mainly concern about the strength, generally masonry mortar does not consider the degree of fire resistance

Q: Whether the cement kiln refractory bricks belong to hazardous waste or not?: Refractory brick produce dust hazards if it is broken, It is also should be paid attention to that if is refractory brick containing chromium, which will easily produce Cr VI when met with water, Cr^6+ material produced by magnesia chrome bricks is difficult to be damaged in the environment, which in many cases will exist in nature for a long time, continue to endanger human health. Chromite, as the raw materials to make magnesia-chrome brick, often exists in the form of trivalence (Cr203), is not toxic, nor carcinogenic, but in the cement rotary kiln high temperature oxidation atmosphere, it reacts with alkali metal oxide in cement materials, will produce chromic acid and alkali acid which is harmful to people's health. There are MgOIn contained in broken magnesia-chrome bricks, whose water solution is weakly alkalinity and generally will not easily produce K2cr207. K2Cr04 is a kind of weak oxidaiblity chemical compound, which has high chemical stability. It is very difficult to be reverted to non-toxic trivalent chromium when it blends into the environment. In many cases, these chemical compounds containing Cr VIcompounds will exist in nature stably, causing long-term pollution to the environment. This kind of harm is sustainable. The second reason that is very serious is that the high grade chrome ore is less and less in the world, forcing refractory manufacturers to find and develop

Q: what effect does big mortar joints of the boiler refractory brick have on the boiler?: The ventilation leakage。 Now the larger boilers are generally used refractory pouring material one-time pouring, the arch is easy to collapse . 2, shrinkage and expansion of brick will make the bricks fall. 1, do not use the refractory brick. too large seam will effect the tightness of furnace wall , and the water wall is easy to form dew and be corroded and to leak smoke.

Q: What are the materials for building blocks and what are the specifications?: Material: clay brick, shale, coal gangue brick, fly ash brick, lime sand brick, concrete brick etc..

Q: What are the ingredients of brick?: Artificial small bulk building, divided brick (clay brick) and non sintered brick (sand lime brick, fly ash brick etc.), commonly known as 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 are the disadvantages of sintered clay bricks?: Fired common bricks are made of clay, shale, coal gangue or fly ash as raw materials, and the solid or hole ratio after roasting is not greater than the specified value, and the size of the bricks meets the requirements.

Q: How much fireclay is needed per cube refractory bricks?: Normal refractory bricks need to use 70-80kg refractory mud each cubic . In fact, this can be calculated, because the volume of refractory bricks and refractory mud density can be measured. Of course, here is an important point, that is the size of the brick seam, 1mm brick seam and 3mm is significantly different. Sichuan brand refractory mud has many kinds, like high aluminum, clay, corundum, magnesia, insulation and so on, the dosage is different.

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.

Q: What kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?: 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: does 90m high reinforced concrete chimney need firebrick?: The chimney need firebricks or casting fire or acid resisitant concrete after casting, one aim is to resist high temperature, then is to resist acid corrosion. there is a variety of models of the refractory brick , you can refer to the installation quota.

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.
