Q: There are various refractory materials inside many kilns such as refractory brick, what is the role of masonry of these refractory materials?: High temperature prevention, warmth keeping and heat insulation.

Q: What kind of refractory brick is suitable for clinker production line of 2,500 tons?: are you saying the cement plant rotary kiln?

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: 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: What's the price of clay bricks?: Clay brick in the fast price of 2.4 yuan or so, the price of 650-800 yuan per ton. Mainly depends on the amount of aluminum. Clay brick consists of heavy clay brick and light clay brick.

Q: the refractory brick in glass furnace burner was burning, the bricks on both sides of the fire hole were burning the blocked it, what will cause brick burning?: The firebrick in glass melting furnace is mainly consisted of zircon brick, other ordinary refractory materials can not effectively prevent the erosion of glass solution. Because the glass melting liquid is eutectic mixture compared to the refractory bricks, it penetrates into the refractory brick and reduces its original performance, simply speaking, the glass melting liquid dissolves the refractory bricks as eutectic mixture .

Q: Do refractory bricks insulate heat?: The light brick inside the brick is heat insulation brick, according to the different bulk density, the effect is also different

Q: Which is the higher price of concrete solid brick and MU15 fired common brick (non clay brick)?: The price of concrete solid bricks and the price of MU10 bricks are on the same level, and the difference will not exceed two cents a penny. It should be MU15 sinter ordinary brick is more expensive.

Q: how to test the high alumina refractory brick mixed alumina?: The first thing before producing bricks is to test whether the aluminum content reaches the standards, general testing on raw materials. Second: the shaped high aluminum brick will be tested in some professional equipment, you can know it from the professional inspection departments.
