Technical data:
Q1 What’s the transport method?
A1 FCL delivery goods with wooden pallet or wooden case by sea; If LCL delivery, must with wooden case; Sometimes need open top, flat rack or bulk cargo.
Q2 What’s the required payment term?
A2 Generally 30% TT as the prepayment, 70% TT before delivery. If need, 100% Irrevocable Letter of Credit or negotiation.
Q3 Which country are our products exported to?
A3 Apart from entire Chinese market, the US, Russia, Japan, Korea, Australia and some Southeast Asian Nations.
- Q: What are the differences between high alumina brick and high alumina refractory brick?
- with the increase of the fire temperature and other indicators, Al2O3 content is also improving. the general content of Al2O3 in high alumina brick is more than 60% .
- Q: Lining of refractory bricks in rotary furnace
- The lining now is built with MgO-C brick, the specific time to change it mainly to see the quality and usage of MgO-C brick. A few years ago, the mills are desperately seeking furnace age, some can use thirty thousand furnace, by the way, furnace age of converter refers to the number of steelmaking furnace not time. So now most mills are not simply pursuit furnace age, but economic furnace age, currently furnace age of steel mills around us is mostly in about ten thousand to twenty thousand. In general, the furnace service of the converter is arranged with the overhaul of other equipment. This can realize the synchronous maintenance of various equipment. If the stove is too old but the maintenance is not timely, also is not to replace the lining brick timely, there will be leakage, then the furnace shell and even ring will be damaged, consequences are more serious . The reason is very simple for brick falling off. One is the poor quality of furnace brick,causing brick lining loose, rocking furnace will lead lining brick falling. the other one is the furnace lining brick is pressed too tight in the use procedure and the brick is too thin.
- Q: Why can earth make bricks?
- In addition to clay, or as raw materials for preparation of brick by using fly ash, coal gangue and shale, which is due to their chemical composition similar to clay, but because of the fineness of less clay, so the poor plastic bricks often to be mixed with a certain amount of clay, in order to increase the plasticity. The use of coal gangue and fly ash and other industrial waste residue brick, not only can reduce the environmental pollution, saving large areas of farmland clay, and can save a lot of fuel coal. Obviously, this is an effective way to use the waste materials and make waste into treasure. In recent years, non sintered brick has been developed both at home and abroad. Such as non sintered clay brick is used is not suitable for farming, waste mud and sand soil, adding a small amount of cement or lime as solidifying agent and trace additives and the amount of water mixing, molding, natural curing or steam curing time is.
- Q: What kind of material is good to be laid on the kiln car, refractory brick?
- Use blankets to suspend ceiling, and modules for wall
- 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: How are shale porous bricks and clay porous bricks distinguished?
- Dimensional deviation is less than clay brickBecause the plastic index is better than that of clay shale itself, although the requirements of the national standard for the size deviation of sintered brick is the same, but the size deviation of shale in actual production is generally less than the clay brick.
- Q: can Methanol burn refractory brick?
- The upper part of the radiation chamber of the methanol oven is made of ceramic fiber, and the lower part is generally used refractory brick.
- 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: what kind of refractory brick is suitable for 1300 degrees converter?
- The furnace cap tapping shaft part should use MgO-C brick with high slag resistance and thermal shock resistance, the steel side can be slightly thin, bottom carbon content may be appropriate less.
- Q: Are buildings allowed to use red bricks?
- Is the red brick with clay, shale, coal gangue as raw materials, crushing, mixing kneading with artificial or mechanical pressing, sintering and building bricks after drying at 900 centigrade temperature by oxidizing flame firing. Also called clay brick. Red brick technical specifications are generally from 75 to 100. Ordinary fired brick (red brick) is also called standard brick. The size is 240*115*53. (mm) red colour, sometimes dark. Ordinary clay brick has a certain strength and durability, but also because of its porous and has a certain insulation, heat insulation, sound insulation and other advantages. Therefore, it is suitable for wall materials and masonry columns, arches, chimneys, floors and foundations. Old buildings use it as building materials. Invented by the Romans, many of the remaining classical structures in Europe had red brick and brick roofs and walls.
