Fireclay Brick with Al2O3 Content around 36%

Q: How can refractory bricks be punched?: refractory bricks, ordinary refractory bricks, electric drill is ok corundum brick, need buy special drill

Q: Can someone tell me the refractory brick in the boiler mixed with what material to build the wall, and what proportion?: Go to the refractory factory to buy some refractory clay that has the same texture of refractory bricks, the general boiler use clay refractory mortar.

Q: What are the disadvantages of sintered clay bricks?: Fired common bricks are made of clay, shale, coal gangue or fly ash as raw materials, and the solid or hole ratio after roasting is not greater than the specified value, and the size of the bricks meets the requirements.

Q: Why can't build refractory brick behind the skew block?: Refractory is heat expansion and cold contraction, when it is high temperature, it will squeeze toward the center and the vault will be deformation .

Q: What is the sintering of non clay bricks?: According to the different production process of bricks into sintered brick and non sintered brick. Sintered brick in China has more than two thousand years of history, is still a very wide range of wall materials.

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: What material are used to burn firebrick?: Alkaline series of refractory bricks &#47, can be classified into five types. Refractory bricks are generally made from refractory clay (white clay) or other refractory materials. Refractory brick according to the composition of refractory material, that is, silicon aluminum refractory brick / carbon containing refractory brick / thermal insulation refractory brick/ zirconium containing refractory brick &#47

Q: cement concrete What kind of cement should be used to manufacture high temperature resistant Kang cement?: Sulphate aluminium cement is the best choice.

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: Can porous clay bricks be made of 12 walls to bear weight?: Porous brick using cement as binder, and sand, stone (aggregate) by adding water and mixing, molding and maintenance made with a plurality of rows of holes of the concrete products; after ordinary and lightweight aggregate concrete small hollow block and a variety of new wall materials.
