Application of High Alumina Brick UAL75
High Alumina Bricks UAL75 are mainlyused:
1). As lining components for the high temperature industries furnace (such as refractory, electronics, ceramics industries).
2). As Thermal insulation components for the high temperature heating equipments, such as gas making furnace, gasification furnace of petrochemical industry, reacting furnace of off-colour industry, electric induction furnace of metallurgical industry.
- Q: How are the high alumina bricks fired?
- Light and high alumina bricks are usually fired in a weak oxidizing atmosphere. In light and high alumina bricks firing, they are often rich in impurities such as R2O, RO, Fe2O3 and so on. They react with Al2O3 and SiO2 at high temperature to produce liquid phase. In the Al2O3 - SiO2 - R2O system, the growth rate of liquid phase increases with the increase of temperature at high temperature. So, because the increase of sintering temperature brings a lot of liquid phase, the decrease of liquid viscosity will lead to the deformation of brick and the decline of brick high temperature function. Therefore, the lower sintering temperature and longer holding time should be adopted in the sintering process dominated by liquid phase sintering. The production practice shows that the same firing temperature can be used for the high grade aluminum bricks. When fired in an inverted flame kiln, it is usually 1430 degrees centigrade and insulated by 40H. The high alumina bricks such as Ill are 1390~1420 degrees centigrade. When the tunnel kiln is fired, they are 1550 and 1450~1500 degrees centigrade respectively. High alumina brick is usually made of weak oxidizing atmosphere.
- Q: Corundum, high alumina and fireclay refractory difference is what
- They differ in that the alumina content is different, and the content is in order: corundum > high alumina > clay.
- Q: What are the high temperature refractory mortars made of?
- Products used in metallurgy, building materials, machinery, chemical, power industry, industrial thermal furnace, for masonryBuilding clay brick, high alumina brick and corundum brick have the characteristics of full grey seam, good airtightness, high bonding strength, high temperature performance and suitable construction time
- Q: What are ordinary bricks, refractory bricks, hollow bricks?
- 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 (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, brick, brick and other specific type. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature. For example, refractory clay brick, high alumina brick, brick, brick etc..
- Q: What does refractory consist of?
- According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
- Q: How high can aluminum bricks expand at 80O degrees of heat?
- When an object is heated, the particle moves faster and thus occupies additional space. This phenomenon is called dilation.
- 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: 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: What is the difference between fireclay bricks and high alumina refractory bricks?
- A neutral refractory with an alumina content of more than 48%. Made from alumina or other raw materials of high alumina content; formed and calcined. High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining.
- Q: What are the lining structures of lime rotary kilns and what are the requirements for refractories?
- The current configuration of domestic calcining active lime rotary kiln refractories are as follows: the discharge end of low cement high alumina castable with 3% steel fiber; the cooling zone and the firing zone: dry magnesia spinel brick with high aluminum brick with high temperature; preheating: high alumina brick; low temperature preheating zone: clay brick light clay brick; feeding end: low cement high alumina castable with 3% steel fiber; in addition, brick size also have the corresponding requirements; dimensional tolerances: dimensional tolerances used in different parts of the requirements are not the same, the general control in 2mm; corner damage: general permit edge damage 40mm and 5mm deep within angle loss in the hot and cold surface is allowed to have only one, three edges and the length of not more than 50mm; there are cracks parallel to the use of surface crack is not allowed, cracks of brick surface are allowed.
