Q:What is the meaning of special shaped refractory brick material n-2b?
In fact, there are many kinds of refractory bricks, titanium, high alumina refractory brick, after drying. The mineral composition of the clay brick is mainly kaolinite (Al2O3·2SiO2·2H2O) and 6% ~ 7% impurities (K, etc.). Clay refractory bricks are iron oxide sintered by 50% soft clay and 50% hard clay clinker ingredients according to a certain granularity requirements under the high temperature of 1300 ~ 1400 degrees), perlite
Q:What is the proportion of lightweight fireclay bricks?
It is a lightweight refractory product containing aluminium 30%-46%. It is made of clay clinker or light clinker as the main raw material. It is usually produced by combustible material. It can also form porous structure by chemical or foam method.
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:Which is best of refractory brick press machine?
Rub press machine have been forced out. Without permanent magnet. The electric screw press machine is suitable for the forming of refractory bricks. Use Kehui switch reluctance to servo motor to drive electric screw press machine, have the ability of high quality electric screw press machine, no water cooling, high efficiency and energy saving, green and environmental protection.
Q:Why can earth make bricks?
In addition to clay, or as raw materials for preparation of brick by using fly ash, coal gangue and shale, which is due to their chemical composition similar to clay, but because of the fineness of less clay, so the poor plastic bricks often to be mixed with a certain amount of clay, in order to increase the plasticity. The use of coal gangue and fly ash and other industrial waste residue brick, not only can reduce the environmental pollution, saving large areas of farmland clay, and can save a lot of fuel coal. Obviously, this is an effective way to use the waste materials and make waste into treasure. In recent years, non sintered brick has been developed both at home and abroad. Such as non sintered clay brick is used is not suitable for farming, waste mud and sand soil, adding a small amount of cement or lime as solidifying agent and trace additives and the amount of water mixing, molding, natural curing or steam curing time is.
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:What material are used to burn firebrick?
Alkaline series of refractory bricks /, 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 /
Q:T38 size of high alumina refractory brick
230*114*65/55
Q:What is the perservation method for refractory bricks used for cement kiln?
The hydration resistance ability is better than the alkaline materials, 1 years will be no problem if the environment is good, alkali-resistant bricks used in cement kiln brick refractory brick (magnesia-chrome brick, the preservative time will be longer, the remaining products should also be moistureproof. No matter what refractory materials, phosphate brick. If the package is complete, it must be stored in a dry and rain-proof environment, silmo brick. Anti-stripping alumina brick, if is not immediately used, it's necessary to take measures of moisture proof, such as spinel brick must be moisture-proof
Q:What is sintered non clay brick?
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. Many kinds of brick, according to the raw materials used for clay brick, shale, coal gangue brick, fly ash brick, lime sand bricks and slag brick;
