General Information of Fireclay brick

Our corporation produces a 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.

1. Carbon bakedfurnaces in the alumina industry

2. Preheat zonesand cyclones of rotary cement kilns

3. Insulation forglass tanks

4. Coke ovens

5. Blast furnaces

6. Reheatingfurnaces

7. Suspended roofs

8. Lime kilns

9. Chimney

Q:The advantages of using alkalinty refractory brick?
Magnesia chrome and other spinel refractories alkalinity refractories; (2) the alkalescent chrome magnesite refractories, alkaline solvent resistance is strong, usually refers to the magnesia refractory material, dolomite brick and calcareous refractory materials, dolomite refractory materials and lime refractory materials, acid flux or acid refractory chemical reaction. Mainly used in alkaline steel furnace and non-ferrous smelting furnace. Alkaline refractory material at high temperature for alkaline slag. Mainly as the following categories, but the acid slag, forsterite refractories and magnalium: (1)strongly alkaline magnesia brick, magnesia carbon brick and cement kiln
Q:Lining of refractory bricks in rotary furnace
The lining of the converter is probably a furnace, but if it is changed at least to see the material and the use of it. There are a lot of damage to the lining, such as: The total impurity content reduces to 2%, lining life will increase 20%-40%; CAO in brick is of 60%-80% content , lining life are the highest; also some other proper index can not be ignored such as bulk density,heat/thermal shock resistant performance,porosity,thermal expansion,fracture resistace,volume stability,Slag resistance,and so on. In addition, lining erosion rate is the largest when the basicity of slag is 1, with the increase of basicity, erosion rate decrease rapidly, the temperature can cause cracks spalling of lining. At the same time, the building process is also very important.
Q:How much refractory material is required for 1 million tons of coke oven
This depends on the number of specific cubic, different factory designs different boiler, we need volume to caculate.
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:How to test the various components of the refractory brick?
It is difficult to distinguish if it is mixed together, fully smashing and mixing. Then assay. Or testing after smashing and separating.
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:In tunnel kiln, what is the meaning of refractory proportion 2.0?
That is the volume density of the refractory brick
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.
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:th choose of different refractory bricks in the rotary kiln
According to the characteristics of each belt, magnesium chromium brick. Take the most kiln foe example, the configuration of kiln refractory is not the same, the burning of the product is not the same. there are many kinds of rotary kiln. magnesia bricks are generally used in high temperature zone, anti-stripping alumina brick,silmo brick are used in temperate zone, clay brick is mainly used in low temperature zone. generally inlet and the outlet use corundum mullite, wear-resistant castable, spinel brick,etc. select brick of proper performance, but also take into account the economy
