It is a kind of the light weight refractory products which contains the alumina content range from 10% to 15%.
Ingredients and water mixed together made the plastic pug or slurry, then Extruded-Form or moulding by casting, dry, and firing in the 1250-1350°Coxidizing atmosphere.
Mainly used as thermal insulating layer without the liquid melt touched or gas pickling in the constructing the various industry furnaces.
- Q:Development prospect of refractory bricks
- Should increase the intensity of adjusting; masonry method is improper, excessive pressure damages the refractory brick, and its ingredients. In use, to reduce the consumption of refractories clinker. Use pleonaste bricks to replace magnesia chrome bricks directly, after deliberation, the experts present agree unanimously to adopt the draft standard, meet the needs of the new situation, to promote the cement kiln refractory standardization, small thermal expansion rate, fluctuation of product quality, good thermal shock resistance of high alumina brick. Of course, in the process of testing, automation level is low, saving energy. The reasons of refractory life is not high are that the production equipment of manufacturers are out-dated; fine management level is low, some companies began to develop energy-saving products, cultivate leading enterprises. Reduce the heat consumption of clinker tons, which effectively avoid the chrome pollution in the next few years, will promote the elimination of backward production equipment. To increase cooperation efforts on industry, education and research, to promote industry to develop to large-scale and intensification the requirement of firing and fuel In order to solve the problem of short service life of refractory material, the size deviation is large, cement enterprises should take measures aiming at the process conditions and raw material of cement kiln.
- Q:air-cooled razheng times of magnesia-alumina spinel refractory bricks
- The ingredients are magnesium, oxygen, and aluminum. the components of spinel refractory can be magnesia-alumina spinel with excessive aluminium oxide, or magnesia-alumina spinel with excessive magnesium oxide. excessive magnesium oxide and aluminium oxide can form magnesia-alumina spinel in above 1700 degrees.
- Q:does the furnace wall use refractory bricks to keep the heat? Or use the insulation material to keep heat ?
- The furnace arch and the furnace wall are all refractory bricks, and the refractory brick is a kind of thermal insulation material!
- Q:does the electric kiln burner need to be sealed?
- seal when open the kiln, and observe the temperature, when the temperature reaches a point, you can move the firebrick away, and continue observing the temperature to decide whether to seal it or not, but do not seal it completely, repeat the procudure until reach the sinter point or skill requirement.
- Q:Which is the higher price of concrete solid brick and MU15 fired common brick (non clay brick)?
- On the wall to change the gradual implementation of the policy process, as excessive wall material, porous clay brick wall reform in some areas has completed his mission to history, new material shale and shale gangue to replace clay brick emerging. In order to promote the application of porous brick technology (Kong Xin), to further implement the policy of building energy saving and wall reform work, put forward the national standard design atlas "porous brick wall building structure" 96SJ101 "and" 96SG612 structure of porous brick wall revision work of the 2003 China building standard design and research institute.
- Q:What are the disadvantages of sintered clay bricks?
- Advantages: brick is the traditional wall materials, has high intensity and durability, but also because of its porous and has the advantages of heat insulation, sound insulation and absorption, therefore suitable for building envelope, interior walls, exterior walls, columns, arches, chimney, channel and other structures have been widely used in masonry the building, is also available in mid proper or steel wire reinforced masonry concrete structure to replace the post and lintel.
- Q:the refractory brick in glass furnace burner was burning, the bricks on both sides of the fire hole were burning the blocked it, what will cause brick burning?
- The firebrick in glass melting furnace is mainly consisted of zircon brick, other ordinary refractory materials can not effectively prevent the erosion of glass solution. Because the glass melting liquid is eutectic mixture compared to the refractory bricks, it penetrates into the refractory brick and reduces its original performance, simply speaking, the glass melting liquid dissolves the refractory bricks as eutectic mixture .
- Q:Solid brick and clay brick which is expensive
- Red brick generally refers to sintered clay bricks. Generally divided into standard brick (Shi Xinzhuan), porous brick (KP brick), hollow brick (KM brick) and so on.
- Q:what is application of high alumina refractory brick?
- reverberatory furnace 1, close to the neutral refractory, but because mullite crystallization has not formed the network organization, so the load softening temperature is not higher than silica brick. the refractoriness of high alumina brick is higher than fireclay brick and semi-silica brick, mainly used in blast furnace, nozzle brick,etc. it is up to 1790 C~ 1750, can resistance to acid slag and alkaline slag erosion. hot blast furnace, blast furnace, high alumina brick are widely used for producing open-hearth furnace regenerative bricks, because it contains SiO2, low impurity content, which belongs to high-grade refractory materials, electric furnace. 2, plug head used in pouring system . In addition. 3, because high aluminum products contains more Al2O3, forming less fusible vitreous body, so the high load softening temperature is higher than clay brick. because rotary kiln lining, slag resistance of high alumina refractory brick contain more Al2O3, so the ability of anti alkaline slag is weaker than anti acid slag. so it has a wide range of application. high alumina refractory brick due to the following performances
- Q:is refractory brick used around the mechanism flue?
