Product Description:

Description for High Alumina Fire Brick:

CNBM High Alumina Fire Brick are classified according to alumina content ranging from 48% to 90%. The kiln shell is made from rolled mild steel plate, usually between 15 and 30 mm thick, welded to form a cylinder which may be up to 230 m in length and up to 6 m in diameter. This will be usually situated on an east/west axis to prevent eddy currents.

Upper limits on diameter are set by the tendency of the shell to deform under its own weight to an oval cross section, with consequent flexure during rotation. Length is not necessarily limited, but it becomes difficult to cope with changes in length on heating and cooling (typically around 0.1 to 0.5% of the length) if the kiln is very long.

 

 

Product Applications:

CNBM High Alumina Fire Brick are commonly used in blast furnace, hot blast furnace, the roof of electric furnace, teeming ladle, rotary kiln, regenerator, etc.

 

Product Advantages:

CNBM conforms strictly to the requirements of ISO 9000 quality control system during the production. MSDS is also available if you want. The thermal insulation fire clay brick meet with the requirements of ASTM & JIS standards. So pls stay cool with our quality.

 

Main Product Features:

Low thermal conductivity   

Excellent acid and base slaging resistance

High refractoriness

Excellent thermal shock resistance  

Excellent mechanical strength

Good spalling resistance and wear resistance.

Q:What are the specific raw materials for plastic pallets?
There are two kinds of raw materials for plastic pallets: one is polypropylene (PP) and the other is polyethylene (HDPE).Plastic pallets for logistics storage: pp+pe material, recycled material 10%;Plastic trays for food trays: food grade PP, PE, pc;Polyethylene (HDPE) has excellent impact resistance and cold resistance, and it can resist environmental stress cracking. Excellent chemical stability, good oil resistance. Water absorption and tiny, low permeability, organic vapor transmission rate is larger. Electrical insulation is good, in all frequency range, dielectric properties are extremely excellent.
Q:What's the difference between high alumina refractory bricks and high alumina refractory bricks?
The chemical pH value of high alumina refractory brick belongs to neutral and alkaline refractory brick, and clay refractory brick belongs to neutral and acid refractory brick.
Q:Is glass wool inorganic thermal insulation material?
The use of glass wool, glass wool is usually used as raw materials of various types of insulation materials, such as glass wool board, glass wool, glass wool, glass wool pipe, can be used in the following areas:1) roof insulation, cold protection, sound-absorbing materials; 2) building exterior wall insulation and cold protection; 3) entertainment places, theaters, television stations, radio stations, laboratories, sound absorption treatment.
Q:Are there any differences between insulating bricks and refractory bricks?
The refractoriness of insulating bricks is generally below 1400 tons, while the refractoriness of refractory bricks is above 1400 degrees. 3. density insulation bricks are generally lightweight insulation materials, the density is generally in 0.8-1.0g/cm3, and the density of refractory bricks are basically above 2.0g/cm3.
Q:What causes breakage of refractory bricks?
Refractory brick is a non metal mineral products can be used in the high temperature of 1550 DEG C under belongs to a class of inorganic, used in high-temperature furnace lining materials as protection kiln, which causes damage, usually have these points.Furnace temperature is not clear, there is no corresponding choice of refractory bricks.Physical impact, abrasion and erosion cause damageChemical factors, especially chemical industry, should be made of refractory bricks, which should be resistant to penetration and erosionIV: products from the factory when the factory did not pass the quality inspection standards
Q:What are the main components of high alumina bricks?
High alumina brick materials according to the main mineral phase can be divided into: aluminum silicate minerals, such as sillimanite, kyanite, andalusite, and synthetic mullite.
Q:What is the standard size of high alumina brick?
The country has laid down a number of criteria for the use of refractory bricks to unify market demand.
Q:Which thermal shock stability of clay brick and high alumina brick is good?
Generally, the thermal shock resistance of high alumina brick products is worse than that of clay brick products
Q:What is the density of a super high alumina brick and what is the price?
Super high alumina brick, alumina content of 80% bricks, bulk density of 2.7g/cm3 or more, the factory price of about 1900 yuan
Q:What are the specifications for bricks?
Thecompressive node as a new type of building energy-saving wall materials, which can be used for masonry walls, but also has good thermal properties, in line with the construction of the building module, reduce the loss in the process of construction, improve work efficiency; the hole rate reached more than 35%, can reduce the weight of the wall, save the foundation engineering cost. Compared with common sintered porous brick, it has the characteristics of heat preservation, heat insulation, light weight, high strength and high construction efficiency. The product is made of shale as raw material. It is produced by high vacuum extrusion molding machine and one yard firing process
