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:

- Q: What refractory material does cupola lining use?
- It's made of high quality refractory material: 1770 ~ 2000 centigrade.
- Q: What are the requirements for Rubble backfill height?
- Backfill should be filled with large stones, big face, small face upward, the decoration is stable, and then use small stones leveling, the gap between the stones can be swept into the slag, gravel, so that the gap filled.
- Q: What's the difference between a well type annealing furnace and a box type annealing furnace?
- RT3 series trolley type resistance furnace is a national standard energy-saving cycle type operation furnace. It has super energy-saving structure, adopts fiber structure and saves electricity 30%. Exclusive production of composite high aluminum nails group, car anti-collision sealing brick, automatic sealing trolley and furnace door, integrated rail, without the basic installation, placed on the ground floor can be used. Mainly used for high chromium, high manganese steel castings, ductile iron, roller, steel ball, 45 steel, stainless steel quenching, annealing, aging, and various mechanical parts heat treatment. Features: 1, no noise, no environmental pollution. 2, small heat storage, less heat loss. 3, high temperature control accuracy, furnace temperature uniformity. 4, a high degree of automation, simple. 5, PID programming can be used to set, fully automatic operation. 6, good sealing, long life, safe and reliable. Widely used in chemical, petroleum, food, metallurgy, machinery, light industry, electricity, ships, paper, mining, medicine, central heating and other industrial sectors. With the development of social productive forces, its application in various industries is more and more widespread. Two, pitannealingfurnace (for example: flange heat treatment furnace) use: the furnace for metal parts, such as ring of equipment heat treatment at rated temperature: the furnace is composed of furnace body and a movable furnace cover and control system.
- Q: Which is better, the soft core or the hard core?
- When the current through the wire, it will produce a magnetic field in the vertical plane space of the wire, if there is a current two wire close by in the same direction, because they produce a magnetic field in the direction is opposite, it will produce a repulsive force is due to the magnetic field force. They will mutually inhibit current intensity of the other party, caused by the reduction of current in the wire, this inhibition of each current intensity, we called wire inductance. When the AC current line frequency is high, the inductance is stronger.
- Q: What are the requirements for refractory materials in heat treatment furnace?
- Fire resistance is an important performance index of refractory materials, but it does not represent the highest temperature in actual use of refractory materials. In actual use, refractories also bear certain pressure, therefore, must consider the high strength at high temperature refractory material, which is in high temperature under certain pressure without deformation, such as the NZ-40 refractory refractory degree up to 1730 DEG C, but the maximum temperature is only 1350 degrees celsius.
- Q: The difference between light high alumina brick and heavy aluminum brick
- Lightweight high alumina bricks, commonly called insulating refractory bricks, also known as insulating refractory bricks. First of all, literally, lightweight aluminum bricks and heavy aluminum bricks are very different in weight. Lightweight high alumina bricks, also called insulated high alumina bricks, are designed for insulation and heat preservation. In normal use, the utility model is not directly contacted with the furnace temperature, and is a refractory brick product which is close to the furnace wall and has the function of heat insulation and heat preservation.
- Q: What's the weight of the refractory bricks?
- Referred to as refractory brick. Refractory made from refractory clay or other refractory material. Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick, refractory insulating bricks (Rong Zhuzhuan);
- Q: What kind of material is the general metal case?
- We usually discuss the electromagnetic radiation of computer enclosures, mainly RF radiation, followed by MF leakage.Switch signal of RF radiation from computer high-speed leakage, such as one of the energy radiation is CPU frequency, graphics, display output line, keyboard, is the source of the operating characteristics of the computer leaked out, is also the main part of computer security.For the absorption of radio frequency radiation, the best is the use of copper materials, the use of other metals can also, thickness enough on the line.The most vulgar description is that people can sit in the case is a good thing.
- Q: What are the lining structures of lime rotary kilns and what are the requirements for refractories?
- The physical and chemical properties of refractory materials used in rotary kiln are as follows: physical and chemical properties of refractory materials used in rotary kilnMaterial name: high temperature compressive strength (MPa), softening temperature (DEG C), thermal shock resistance (1100 DEG C, cold water), sub volume density (g/cm3)Magnesia spinel brick is greater than or equal to 50 is greater than or equal to 1700 = 12 = 2.95High alumina brick is greater than or equal to 75 = 1520 = 8 = 2.57High aluminum bricks more than 50 = 1700 = 12 = 1The clay brick is greater than or equal to 30 = 1400 = 12 = 2.30
- Q: What are the categories of bricks?
- In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
