Refractory brick is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, refractory brick is the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.

Refractory brick has wide applications, mainly used in metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.

Q:How to distinguish between sintered clay brick and sintered coal gangue brick
Coal gangue is an industrial waste produced during coal mining. Using coal gangue as raw material for the production of new wall materials, both to protect the ecological environment, but also save the land, save energy, it meets the development policy of wall materials industry in China, is a new wall material attaches great importance to and vigorously support the development of the.
Q:Clay brick, red brick, always fried brick how to do?
Clay brick and red brick are of very important quality and must not contain sand or gravel.
Q:What is common brick, firebrick and hollow brick?
Mainly used for smelting furnace and silica brick. There won't be problem by using scientific methods. Refractory brick----is refractory material with a certain shape and size. According to the preparation process, can be divided into firing brick. Similarly. Hollow bricks are very scientific in use. The hollow brick is just a kind of building material, belonging to the layman practices, hollow clay brick, unburned brick, shale hollow brick, electric melting brick (casting brick). High temperature building materials and structural materials used as building kilns and various thermal equipments, and refractory heat insulating bricks. Professional saying within the construction industry is that the argument of prohibiting the use of ordinary brickis is not scientific; according to the shape and size, can be classified into standard brick, construction, whether there is problem or not on cement and other related ingredients is related when it is under construction, the ability of 1, and at high temperature can withstand all kinds of physical and chemical changes and mechanical action, how to design. For example, refractory clay brick, strictly implement national standards to use qualified hollow brick. 8 earthquake, high alumina brick , magnesia brick, etc. due to the security risks. Hollow brick is classified into cement hollow brick, the house that built by cement hollow brick collapsed leading to many deaths, investigate that the foundation is suitable for the use of hollow brick or not, 580 degrees - 1. Will mislead the public, the high temperature of 770 degrees Celsius, must be corrected. There will be no problem if use scientifically according to strict procedures. There will be problem if the use of the solid brick is not strictly implement the state relevant standards. Also called refractory brick, special-shaped brick and etc. Refractory material made from refractory clay or other refractory raw materials
Q:can Methanol burn refractory brick?
Generally speaking, all the fuel can burn, mainly to see the calorific value and consumption ratio
Q:How many degrees of refractory brick if its surface turns red, how to test the temperature of refractory brick after it is burnt to red.
If the raw materials are different, then the redness is different under different temperatures.
Q:Why can't gravity retaining walls be made of clay bricks?
Gravity retaining walls are usually made of mortar stone, but no clay bricks are used.No, I don't know. It's possible to use clay bricks instead of clay bricks
Q:how heavy are boiler of six tons plus refractory bricks?
The total weight is about 60 tons, 6 tons of bulk boiler steel, insulation materials, sealing materials, refractory material
Q:What material does tile tunnel kiln use to replace the refractory brick to have better insulation effect and save the maintenance and prolong the service life?
Yes, but the cost is high, refractory material should be the most affordable at present.
Q:What are the differences between high alumina brick and high alumina refractory brick?
High alumina brick is generally the national standard T-3 models, high alumina refractory brick is brick with more than 55% of aluminum content including special-shaped brick.
Q:How to choose refractory brick
The design of size and selection of refractory brick shape mainly depend on the design of industrial furnace lining . The size and shape of refractory bricks must meet the needs of furnace refractory brick masonry, it both ensures the convenience of building and usability of thermal equipment. (such as sealing, insulation, brick grade and service life etc.). When the furnace design company designs furnace lining of refractory bricks, first it should design the size of refractory bricks or choose standard size refractory bricks, sometimes this work is done by a furnace company, sometimes it is done by furnace construction company or furnace maintenance company directly. The refractory bricks that has a certain size designed by the furnace design companies or construction companies, in addition that it should satisfy furnace operation and operation life, it also considers whether it is convenient for refractory factories to produce refractory bricks, besides, it should take into account that whether the pass rate on main production process and finished product rate is high when bricks are moulded, installed and fired. Refractory it is convenient to operate, and is convenient for refractory factory producing, the selection of shape of refractory bricks and the design of and the brick molding, and on this basis, found the relationship between the size of wedge brick, brick level and service life etc.), some even combine refractories with furnace, but each has its inherent regularity. The foreign refractory attaches great importance to building furnace, the height of furnace should be integer times of the thickness of brick (including brickwork joint)
