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

Q:What are the main raw materials of refractory brick and runner brick?
Types of refractory bricks are divided into low-grade and high-grade. generally, siliceous, semi siliceous and high aluminous runner brick brick have higher requirements. If it needs to contact melting in high temperature molten steel directly, then it is high alumina(the main raw material is clinker of bauxite with high alumina, corundum( brown corundum and white corundum), the refractoriness is high, lower than 1580 DEG C temperature, but the actual using temperature reaches 1630 DEG C
Q:Development prospect of refractory bricks
Should increase the intensity of adjusting; masonry method is improper, excessive pressure damages the refractory brick, and its ingredients. In use, to reduce the consumption of refractories clinker. Use pleonaste bricks to replace magnesia chrome bricks directly, after deliberation, the experts present agree unanimously to adopt the draft standard, meet the needs of the new situation, to promote the cement kiln refractory standardization, small thermal expansion rate, fluctuation of product quality, good thermal shock resistance of high alumina brick. Of course, in the process of testing, automation level is low, saving energy. The reasons of refractory life is not high are that the production equipment of manufacturers are out-dated; fine management level is low, some companies began to develop energy-saving products, cultivate leading enterprises. Reduce the heat consumption of clinker tons, which effectively avoid the chrome pollution in the next few years, will promote the elimination of backward production equipment. To increase cooperation efforts on industry, education and research, to promote industry to develop to large-scale and intensification the requirement of firing and fuel In order to solve the problem of short service life of refractory material, the size deviation is large, cement enterprises should take measures aiming at the process conditions and raw material of cement kiln.
Q:What are the differences between diatomite brick and ordinary refractory bricks?
The volume density of diatomite brick is 3.9 * 10-6, good compressive strength, belongs to the small outer insulation, spinel brick.
Q:What is the specific heat of a refractory bricks (clay)?
Approximately it's about 2000; M3 specific heat is wrong with this argument, two degree clay is 1730 degrees, three degree clay is 1690 degrees, clay bricks are mixture, bulk density, 1900KG/, only elementary substance has specific heat refractoriness.
Q:The difference between fireclay brick and refractory cilica brick in the application.
Good thermal shock stability, long-term use temperature is not higher than 1300 degrees, high temperature, high strength, low price of clay brick characteristics, thermal shock stability is the worst, a scrap, can be long-term used under the condition of high temperature (exceed 1400 degrees Celsius) . The temperature of silica brick's soft bearing is close to the melting point. Other industries basically don't use, but the comprehensive performance of high temperature is not good, widely used in low temperature parts of a variety of furnaces. The silica brick is generally used in the coke oven and glass kiln, but anti alkali erosion ability is poor
Q:Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
Heat insulation cotton is laid behind refractory brick.
Q:Do refractory bricks resist corrosion and sulfur?
There are anticorrosion and acid proof refractory bricks
Q:What materials mix mortar to build walls (with bricks)? The more burned the harder
Refractory mortar
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 should be paid attention when the refractory brick kiln furnace reaches a certain service life and will be removed?
