- Q: What's the difference between a well type annealing furnace and a box type annealing furnace?
- 1. The shell of the furnace is welded by section steel and steel plate. 2, the furnace cover support adopts steel and guide rail combination mobile type. 3. The heating element is made of high resistance alloy 0Cr25Al5 produced by Beijing Shougang Group and arranged on the furnace side. 4, because the bottom bearing adopts high aluminum bricks, the circle center of the furnace set small, inside and outside heating. 5 、 furnace cover adopts hydraulic lifting, motor control, automatic walking. 6 、 temperature control system adopts PID SCR control, high accuracy.
- Q: What is the price of the first grade high alumina brick?
- Many factories in Xinmi have high alumina bricks, but they must choose a regular factory. Kuwait refractory level high aluminum brick price at around 1600, the quality of double stable supply
- Q: Density of high alumina bricks
- Alumina content of 48% or more, mainly from mullite and glass phase or corundum composition of lightweight refractory. The volume density is 0.4 ~ 1.35g/cm3. The porosity is 66% ~ 73%, and the compressive strength is 1 ~ 8MPa. Better thermal shock resistance.
- 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: How to make refractory bricks and boiler wall adhesion more firm?
- Suggest that you use fire brick to increase the length of brick or pull the amount of turn, and use high temperature mortar masonry
- Q: What are the characteristics of high alumina bricks?
- The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized high-temperature kilns and other energy consuming industries, such as chemical industry, electric power industry, etc.
- 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 is spalling resistant high alumina brick?
- Using bauxite as main raw materials, the introduction of a small amount of ZrO2 (ZrO2 is due to phase transition, between monoclinic and tetragonal type can improve the thermal stability of the products), adding a certain amount of binder and additives, the particle size distribution control mud, forming and sintering of refractory products produced, called anti stripping high alumina brick.
- Q: What are ordinary bricks, refractory bricks, hollow bricks?
- Hollow brick is divided into cement hollow brick, clay hollow brick, shale hollow brick. In March 2011 Yunnan Yingjiang earthquake occurred in 5.8, the use of cement hollow brick houses collapsed and killed several people, due to safety concerns that Yunnan intends to disable the cement brick, Shandong Qingdao in the construction of real estate has also been halted the use of cement hollow brick. Professional claims in the construction industry argue that the prohibition of the use of such statements is unscientific and unprofessional. Misleading the public, it must be corrected. Hollow brick is only a kind of building material, and it is no problem to use it in scientific way. Hollow brick in use is very scientific, high quality requirements, the investigation of the foundation is suitable for the use of hollow bricks, how to design, construction, cement and other related ingredients, there are no problems. According to strict procedures, scientific use, strict implementation of relevant national standards, the use of qualified hollow bricks, there is no problem. Similarly, if the use of solid bricks does not strictly comply with the relevant standards of the state, the same will be a problem.
- Q: The difference between ordinary and diatomite brick refractory brick
- To say the difference, the material is the biggest difference. There are diatomite brick density, compressive strength of small brick kiln belongs to the outer thermal insulation, and heavy refractory brick kilns for multi village in direct contact with the flame, high temperature resistance, good compressive strength, but no insulation.
