High alumina EPS insulating brickNormally used in the insulating layer of industrial kilns and furnaces. With higher strength than clay/high alumina insulating bricks.
Magnesia carbon brickUsed in working layer of ladle, refining ladle, converter, electric arc furnace, etc..
Alumina-magnesite carbon brickUsed in working layer of ladle, pig iron ladle, electric arc furnace, etc..
Magnesia-calcium brickUsed in working layer of electric arc furnace, refining furnace like AOD, VOD furnaces, etc..
Magnesite-chrome brickUsed at high temperature zone and firing zone of rotary cement kiln.
Magnesia brickUsed in permanent layer of converter, AOD furnace,  etc..
AZS brickNormally used at glass melting furnace hearth.
Silica brick

Partition wall of carbonization chamber and firing chamber of cock oven; Regenerative chamber and slag pocket of steelmaking open hearth 

furnace; Soaking pit furnace; Glass melting furnace; Weight bearing areas such as vault of the calcining kilns of refractory silica brick and ceramic; 

Weight bearing area of airheater; Roof of acid open hearth furnace.

Checker brickRegenerative chamber of blast furnace hot blast stove,  flame furnace.
Anchor brickNormally used to strengthen refractory layers of industrial furnace or flue, or is used when the furnace body structure is too thick or overload or 

the temperature at working area is too high.

Baffle brickMainly used in regenerative chamber of heating furnace.
Purging plugBlowing gas into the molten steel through it.
Purging plug seat blockPurging plug seat block
Low carbon brickNormally used in the working layer of refining ladle, producing high class steel.
Carbon free brickNormally used in the working layer of refining ladle, producing high class steel.
Alumina magnesia spinel brickMostly used at transitional area of rotary kiln.
Corundum brickWidely used in many kinds of furnaces or kilns.
Al-SiC-C brickWidely used in the working layer of blast furnace, foundry ladle, metal mixer, molten steel trough, etc..

Q:What is the difference between cement foamed thermal insulation board and thermal insulating brick?
The main difference between cement foamed thermal insulation board and insulating brick is that the shape is different, one is plate, and the other is brick. Both are new walls to achieve the effect of energy conservation and insulation.
Q:What are the types of building blocks?
1. the use of the different parts, building bricks into bricks, floor brick, brick, brick arch shell, brick brick chimney and sewer.2. different building performance, building bricks into bearing brick, brick, brick, non bearing engineering insulation brick, brick, tile, acoustical tile and other flowers.The use of 3. different materials, is divided into building brick clay brick, shale, coal gangue brick, fly ash brick, slag brick, lime sand brick etc..4. according to the shape, the building brick can be divided into solid brick, microporous brick, porous brick and hollow brick. Ordinary bricks and special-shaped bricks, etc..
Q:What is the price of concrete self insulation bricks
If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)
Q:What is a JQK composite lightweight thermal insulation brick?
It is a cement based composite waterproof mortar which is pressed and molded. The material has good heat preservation effect and high thermal conductivity.
Q:How to reinforce a porous brick foundation?
Enlarged section method: it is used for the relatively shallow foundation with independent depth, strip foundation, raft foundation, box foundation and pile foundation applicabilityPoor.
Q:What are the improvements and improvements during the trial production of insulating bricks?
Insulation brick seven characteristics: insulation, heat insulation: effectively reduce energy consumption.Fire prevention: up to national standard or class A.Clean and environmental protection: no two pollution will be caused by air.
Q:What is mullite insulation brick?
According to the application temperature can be divided into: 1350 mullite bricks, 1450 mullite bricks, 1550 mullite brick etc..
Q:What bricks are thermal insulation bricks?
Thermal insulation brick is a new type of building material synthesized with macromolecule material. Grey, hollowed out bricks are basically.
Q:How much is a thermal brick
Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.
Q:Material and making method of light insulating brick
Material production of ordinary light insulating brick clay, high alumina high strength low iron bead brick, mullite, high aluminum light insulating refractory brick, diatomite insulating refractory brick.
