- 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: Is there a big difference between two high alumina brick and one high alumina brick?
- According to my experience, two kinds of high alumina bricks from the index, there is a big difference between the content of AL2O3, a high aluminum brick in 75%, two grade high alumina bricks in 65%, so the content is not the same, also decided that the use of temperature difference, the difference is very big.
- Q: What are the requirements for Rubble backfill height?
- 1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.
- 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: How to distinguish the good or bad of the high aluminum brick?
- Weigh the weight of the next block. According to the weight standard, a high alumina brick is 3.9 kg in weight, two in high alumina brick, three in high aluminium brick and 4.5 kg in 4.2. The same grade, the same type of high alumina brick, if the weight of a single brick to this standard, but for high quality high alumina brick, otherwise, can not reach such a weight, it shows good quality. If there is a crack, a large piece of broken angle, four sides of inequality, it is for substandard products.
- Q: What is the difference between high alumina brick and clay brick?
- Light clay brick, refractory material is a kind of high porosity, low density, low thermal conductivity of refractory material, refractory materials called lightweight refractories, it includes insulating refractory products, refractory fiber and refractory fiber products. Heat insulation refractory material is characterized by high porosity, general 40%-85%, low volume density, lower than 1.5g/cm3, low thermal conductivity, generally lower than 1.0W (m.K). The utility model has the function of heat insulation of an industrial furnace, and can reduce the heat dissipation loss of the kiln, save energy, and can reduce the quality of the thermal engineering equipment. The mechanical strength, wear resistance and slag resistance of insulating refractory material are poor, and it is not suitable for the load-bearing structure of kiln and direct contact with slag, burden, molten metal and other parts.
- Q: How to reduce the harm caused by two times mullite in high alumina refractory material
- Prolong the sintering time and adjust the aluminum content of the high alumina brick.
- Q: Use of high alumina refractory bricks?
- High alumina brick refractory than clay refractory bricks and brick refractory degree are higher, up to 1750~1790 DEG C, which belongs to high-grade refractory materials.
- Q: What is the high temperature limit of refractory bricks and refractory soil?
- Fire clay -- usually refers to folk point stove furnace set with a kind of soil, limit under atmospheric pressure of 1500 degrees fire clay soil 1, properties and uses: clay brick of weak acid refractory material, its thermal stability is good, suitable for hot blast furnace, boiler and flue, smoke chamber lining, etc..2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
- Q: What is the difference between metal compounds and metal solid solutions?
- A series of intermetallic compounds occurring between transition metals in intermetallic compounds. The most important are L sigma sigma phase and ves phase, they are topologically close packed (TcP) phase, they consist of a small atomic radius of a dense layer, which is inlaid with a large atomic radius of atomic structure, this is a highly dense pile. In addition to atomic size factors, their formation is also influenced by the concentration of electrons.
