General Information of Fireclay brick
Our corporation producesa comprehensive range of Fireclay bricks, with 30% to 55% alumina content, allof these bricks exhibit excellent performance.
Our Fireclaybricks are the final result of blending excellent fused alumina and silicon asthe main raw materials with cutting-edge technology, adding superfine powder,after mixing, drying, forming, in the high temperature shuttle kiln. We ensureyou that the Fireclay Bricks made by us possess high quality standard and havegone through all the complicated quality control parameters. Their durabilityand strength adds life to the structure and they have the capacity of bearinghigh temperature.
Feature of Fireclay Brick
Resistant tothermal shock, abrasion, chemical attack
High ability foranti-abrasion during work
Low shrinkagedegree under high temperature so as to maintaining integrity of the furnacelining
Low apparentporosity, and low Fe2O3 content to reduce the carbondeposit in the blowhole and avoid the bricks broken in case of expansion
Applications of Fireclay Brick
Fireclay brick is mainlyused in the part of throat, stack, hearth, bottom for blast furnace and thestack for a big blast furnace.

- Q: Which thermal stability of clay bricks and high alumina bricks is good?
- Thermal shock stability is much better than clay brick.
- Q: Scheme of cement kiln replacing 40 meter refractory brick kiln
- If only replace refractory bricks, it just needs three days under the condition of 200 degrees. It will be simpler if there is only free water in the refractory brick (no pouring material).
- Q: What is the best color of refractory brick
- Date red is better.
- Q: What are the advantages and disadvantages of clay refractory bricks?
- The mineral composition of clay brick is mainly kaolinite (Al2O3, 2SiO2, 2H2O) and 6%~7% impurities (potassium, sodium, calcium, titanium, iron oxides). The sintering process of clay brick is mainly the process of the continuous dehydration of kaolinite and the formation of crystallization of mullite (3Al2O3. 2SiO2). SiO2 and Al2O3 in clay bricks form eutectic, low melting point silicates with impurities during sintering, and are surrounded by mullite crystals.
- Q: What raw materials are used for making refractory bricks
- That is silicon aluminum refractory brick/, it can be divided into five types:thermal insulation refractory brick, alkaline series refractory brick, refractory brick containing zirconium, carbonaceous refractory brick/. Refractory bricks are divided according to the ingredient of refractory. Refractory bricks are generally made from refractory clay (kaolin) or other refractory materials.
- 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.
- Q: What can be applied to the burned refractory brick to resist heat shock?
- Acidic refractory material use monox as the main component, among which cilica brick and clay brick are commonly used. Silica brick is silicious product containing monox more than 93%, whose raw materials include silica, waste silica brick scrap and etc. The acid resistance of slag erosion ability is good, and the softening temperature under a fixed load is high. The volume won't shrink after repeated burning, but even a slight expand; but it is vulnerable to the erosion of basic slag, and has low thermal shock resistance. The silica brick is mainly used for coke oven, glass melting furnace, acid hearth furnace and other thermal equipments. Clay brick uses refractory clay as the main raw material, containing 30% to 46% of aluminuum oxide, belong to weakly acidic refractories. It has good heat shock resistance and corrosion stability to acid slag, and it's widely used. Neutral refractory materials use aluminum oxides, chromium hemitrioxides or carbons as the main components. Corundum products containing more than 95% of alumina is a kind of high quality refractory material with wide application.
- Q: can castable refractory replace refractory bricks in rotary?kiln?
- The heat produced in the welding process will cause local deformation of the rotary kiln, which will affect the dynamic balance, and the construction difficulty in the middle position of the rotary kiln is much larger than that of the refractory bricks. Moreover, the construction quality is not easy to ensure, generally only replace the refractory brick in the kilneye, because the construction of the castable refractory need to weld the anchor
- Q: Are clay bricks radioactive?
- Radiation is almost invisible, radiation is almost everywhere.
