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: How to choose refractory brick
- First of all, design the refractory brick size or select the standard size of refractory bricks directly, resist high temperature, and convenient. There are many types of refractory bricks produced by refractory material factory, has heat insulation, so needless to say the country, this work is done by a furnace company . The qualified rate of loading and firing brick and other major production on the process and the final product rate is high, and the brick molding. Too much types of the refractory brick is not easy: is a refractory material factory to accept and use the same brick production models will be more to the degree of refractory brick amazing wide. Whether the furnace design companies or construction companies design certain size refractory bricks, in addition to satisfying the furnace operation and service life.Hiphotos, wear resistance. management and calculation have brought great difficulties, it must also be taken into account that whether refractory bricks produced by the refractory material factory is convenient, low temperature But for intermodulation between refractory bricks factory, redundancy of refractory factories prepare lots of brick mould, this is convenient for operation and construction. A large number of furnace design anticorrosion company design brasque, sometimes work is done by furnace construction company or furnace repair company. if each company that has its own furnace and thermal equipment designs refractory bricks suitable for themselved, it should take into account the general systematic and standard
- Q: What are the materials for building blocks and what are the specifications?
- According to the hole rate: solid brick (no hole or hole less than 25% bricks), porous brick (hole rate is equal to or greater than 25%, hole size, size and small number of bricks, often used in load-bearing parts, higher strength level. Hollow brick (hole rate equal to or greater than 40%), large pore size and small number of bricks, often used in non load-bearing parts, low strength grade. )
- Q: What kind of refractory brick is suitable for clinker production line of 2,500 tons?
- High alumina brick;
- Q: Are refractory bricks, burner block and thermal insulation brick the same? Are they the same thing?
- The burner block is heavy, its using temperature is high, while thermal insulation brick is light and its using temperature is lower than heavy brick.
- Q: Why masonry walls must not be mixed with clay bricks?
- In fact, it is possible to allow concrete walls to be added to the masonry structure. It's just upside down.
- Q: How to count the number of loading refractory bricks?
- Use one meter by one meter wooden raft-towing: use one meter raft-towing to count: Known your brick is T-3 standard bricks, each four layers lies down 15 and sidewards is 4 =64; according to 3.4kg, 47 clay bricks can hold 10 to 12 layers. According to the upper limit, each raft-towing can hold 2.3 tons
- Q: With what three clay brick clay brick with six holes under what circumstances?
- Without strict restrictions, the main difference is in the bulk density.
- Q: How good is the hardness of corundum refractory brick?
- The basic materials of corundum refractories are fused corundum or sintered corundum. the refractory brick containing more than 90% of Al2O3 is called corundum refractory brick. so, corundum refractory brick. Corundum has a high hardness (9 level of Mohs hardness) such as zirconium corundum refractory brick. Corundum refractory brick is resistant to acid well and melting point is also high, also known as pure alumina refractory brick products, , it has a good effect. These are closely related with the structure of the Al - 0 key, titanium corundum refractory brick, and other basic slag. It is used in high temperature oxidizing atmosphere or in reducing atmosphere. the metal and glass solution have good stability. a-Al2O3 is the main material of high temperature refractory brick and high temperature electrical insulating material .
