- Q:How much is the bending temperature aluminum silicon carbide brick for torpedo car
- 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 hot blast stoves.
- Q:How does the physicochemical index change when the high alumina brick is used at high temperature?
- If the range of softening temperature exceeds the load, the constants of other physical and chemical indexes will also increase or decrease.
- Q:What are the specifications for 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.
- 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:In 2016, a few of the traditional refractory materials will be able to survive
- The other is in large enterprises and individual has the unique advantage of the small enterprises, with independent technology system, production equipment advanced, there are certain funds set up to deal with risk, timely reform, such enterprises compared to a few years ago the productivity and sales or have declined, but overall is still in the stage of production increased steadily.
- Q:The cloth blowing is not uniform on the lime kiln refractory brick is damaged it
- Lining 1 yuan to prevent direct damage to the Sindh kiln high temperature flame or air, to protect the kiln carcass; 2, to prevent harmful substances (CO, SO2) erosion of the kiln body; 3, to prevent corrosion, material flow on the kiln body; 4, reduce the kiln temperature, kiln body to prevent oxidation 5, has the function of corrosion; thermal insulation; 6, to improve the coating performance.
- Q:What are the reasons for the spalling of refractory bricks in the production of lime kiln?
- Therefore, the choice and masonry of refractory bricks are of vital importance. If there is a brick kiln kiln off block process of reproduction, is now because of the use of refractory brick kiln material mostly three grade high alumina bricks. The content of AL2O3 is about 55%, of which the content of Fe2O3 is about 2%, which is weak, and the alkali corrosion resistance is a little worse. In a containing three grade high alumina bricks in the composition of AL2O3, Si2O3, and other elements also contain K, Na trace, were the most, thus causing the system of the low melting point is very low, even at 1400 DEG C has been liquid phase, and generate CaAL12O19 limestone and calcium feldspar etc.. Form corrosion loss. Therefore, a long time will cause the loss of block. On the one hand, it may be caused by construction.
- Q:Introduction of high alumina brick
- 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 common thermal insulation materials for thermal conductivity?
- The vacuum heat insulation plate is a kind of high efficiency thermal insulation board made of inorganic fiber core material and high resistance gas composite film. It is made of vacuum encapsulation technology and covered with special interface mortar.
- Q:What should be used as binder for making high alumina bricks?
- In addition, high alumina micro powder can be used as binding agent, or high alumina micro powder and clay powder are prepared according to a certain proportion, and synthetic mullite is used as bonding agent. With these binders, high alumina bricks without two expansion can be prepared.
