CNBMis the specialized manufacturer and supplier of refractory in China, Our products mainly include refractory bricks, refractory castable, refractory precast shape, insulating brick etc. For refractory castable and precast shape they are very popular in the Europe, North American area.

Advantage:

This series of products are made of super calcined flint clay and calcined bauxite, with high pressure formed and high temperature sintered. Due to its low apparent porosity, strong resistance to erosion and high refractoriness under load, they are wildly used in various furnaces, especially suitable to the middle and low parts of regenerator in glass furnaces.

Features:

1. Low bulk density, low thermal conductivity, good thermal performance.

2. Refractory category allow direct contact of fire, suitable for various atmosphere

3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely

Typical Applications:

1. Furnaces of metallurgy industry, heat treatment furnace

2. Furnaces of chemical industry and construction industry.

3. Furnace of incineration of garbage, recirculating fluidized bed furnace

Q: What's the reason of cracks in refractory bricks?: This is inorganic nonmetallic material

Q: Why limit sintering brick first and develop new wall material?: The common brick used in the sintering brick will be used to borrow soil from the farmland, which will lead to the degradation and abandonment of the land. The clay belongs to the cultivated land, and protects the cultivated land in order to protect the precious land resources.

Q: What is the refractory temperature of refractory bricks?: First look at the used parts of refractory brick, anti stripping performance, these are the most basic performance factors, the refractory temperature of high alumina brick is 1770 -1790 degree, the refractory temperature of clay brick is 1380-1570 DEG C, record the anti acid corrosion data of refractory bricks, the compressive strength of refractory bricks, at the same time, you should analyze each part of the furnace pH index and sintering temperature of working. When purchasing refractory bricks, you need to pay attention to many factors, high temperature creep property, softening temperature under a fixed load, 6548, volume stability at high temperature. Because the production of the product is affected by the weather and fuel energy, etc.. 186, select the suitable refractory bricks

Q: Can common cement mortar be used to build the lining of chimney refractory brick?: No. You have used fire bricks, which shows there is a certain temperature inside, you'd better use refractory cement

Q: What is the best color of refractory brick: Clay refractory brick: Yellow and deep yellow; acid-proof brick: Red, high alumina brick Beige, a little white; square viewing brick: Yellow, red, white, gray, brown, brown, nigger-brown and so on; color is just one aspect of the selection of refractory bricks, it mainly is to see the inherent quality

Q: why the color of refractory brick is white after high temperature firing when the meteorite is black after the burning?: There are different reasons. Meteorolites can mainly be divided into three types, iron meteorites (iron nickel alloy): Stone meteorites (the main component is silicate), and stony iron meteorites(the mixture of iron and silicate)

Q: is there any requirement for radioactive materials in refractory materials.: they all do not cause radiological hazards to the environment, so no requirements! analyze rom the element , magnesia. Do not know if it is useful, but material used by refractory materials, firstly any chemical elements are radioactive, human beings can not close, then, such as silicon dioxide: If it is radioactive. analyze from use, such as bauxite, does not have the use value

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: can castable refractory replace refractory bricks in rotary?kiln?: Rotary kiln has special casting material, completely can replace the refractory brick.

Q: How to make the adhesion between refractory brick and the inner wall of the boiler more firm?: Professional furnaceman who can weld pins in the boiler steel plate is needed when have the bricklaying, mortar overflowing, connect with the refractory brick
