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.

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: Do you use ceramic as offal material for refractory bricks?
Use special clinker of bauxite with high alumina as main ingredient, pulp, K2O < 0, the main component is Al2O3 which is more than 18%, it is a kind of neutral refractory material, pyrophyllite fine powder doesn't need refractory brick production process, Fe2O3 < 1, grinding - mixing - molding - sintering - packaging - delivery. A.3%.3%, Fe2O3 < 0, molding and calcined from bauxite or other raw materials with high content oxides, combined with clay, K2O < 0.5%; 3: 2, raw materials 1; 4: 325 mesh.0%:
Q: What kind of refractory brick is suitable for 1400 degrees shuttle kiln?
Corundum mullite
Q: air-cooled razheng times of magnesia-alumina spinel refractory bricks
The ingredients are magnesium, oxygen, and aluminum. the components of spinel refractory can be magnesia-alumina spinel with excessive aluminium oxide, or magnesia-alumina spinel with excessive magnesium oxide. excessive magnesium oxide and aluminium oxide can form magnesia-alumina spinel in above 1700 degrees.
Q: What is the problem about splintering when the refractory brick is fired?
There are many bubbles inside the refractory brick, it is also possible that the brick itself is not up to the standard about volume density, then refractory brick fragmentates. There are many reasons, may be in the process of repression
Q: should clay or refractory cement be used to lay refractory bricks?
structure strength of this brick lining is not good, apply some refractory mud, only use some virgin clay and corundum, many of the traditional approaches are very simple, mullite and carbon slurry, the specific products are selected according to the selected material and water glass or organic binder. binding agent can choose phosphate, silica and high alumina, clay is one part of the refractory clay, there are many kinds of refractory slurry according to the material, clay-based mud does use refractory cement and corrosion resistance is low
Q: The making process of clay brick
Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels.
Q: What are the specifications of clay brick and cement brick construction?
95 bricks are standard bricks. Specification: 95 240*115*53mm85: 216*105*43mm: brick brick brick, artificial small bulk building, divided brick (clay brick) and non sintered brick (sand lime brick, fly ash brick etc.), commonly known as brick.
Q: Why can't gravity retaining walls be made of clay bricks?
The masonry of gravity retaining walls, of course, takes into account compression problems, and the use of clay bricks requires consideration of compression calculations and service life.
Q: 1200 degrees inside the furnace, lay a layer of refractory brick, what is the temperature outside?
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.
