Aluminum Silica Carbide Brick CNBM Made in China

Q: What is the heat preservation material used in a laboratory furnace?: Silicon carbide (SiC) is made from quartz sand, petroleum coke (or coal tar), sawdust (green salt produced when adding green silicon carbide) and other raw materials by smelting with resistance furnace at high temperature. Silicon carbide also rare minerals in nature, Mo sangshi. Silicon carbide, also known as carbon silica. Silicon carbide is the most widely used and the most economical kind of refractory materials in C, N, B and other non oxide refractory materials. It can be called "carborundum sand" or "refractory sand".

Q: What refractory material does cupola lining use?: It's made of high quality refractory material: 1770 ~ 2000 centigrade.

Q: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?: The brick Pei boring and time. 6, Pei brick kiln installed between the brick and the brick Pei order, Pei and kiln top, kiln wall gap etc.. 7, high alumina brick kiln plan, and the lack of edges and corners of the scene should be avoided.

Q: The difference between aluminium refractory and magnesia refractory: Therefore, the difference between the two is a neutral, one is alkaline, the original product is different naturally.

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: Difference between low creep high alumina brick and ordinary high alumina brick: Low creep and high alumina brick is based on the theory of "three stones". The combination of bauxite and clay as the main raw material, adding kyanite, andalusite and sillimanite, commonly known as the "three stone" control, physicochemical index and size composition, using alumina mullite corundum + + raw materials such as technical scheme. In the production process, first to detect and control indexes of raw materials, crushing, grinding, sieving process, according to the distribution ratio of ingredients, the size and moisture control of mud mixing after to meet the requirements of forming and molding machine, the use of qualified abrasives, blow molding control number, size and flash at the same time, the detection efficiency of semi-finished products and meet the requirements. Production process: high temperature calcination of high-grade alumina, adding small creep rate of high temperature materials, by high-pressure molding and high temperature firing. It has the characteristics of high strength, low creep rate and high use temperature. Widely used in high temperature furnace, hot air furnace hearth lining, brick and so on.

Q: What does refractory consist of?: Refractory materials can be divided into main raw materials and auxiliary raw materials according to their function in the production process of refractory materials.The main raw material is the main body of refractory. Auxiliary raw materials can be divided into binders and additives. The role of bonding agent is to make the refractory body in the production and use process has enough strength. There are commonly used lignin, phenolic resin, asphalt, cement, water glass, phosphoric acid and phosphate, sulfate, some main raw material itself has the effect of binder, such as clay; additive is to improve the production of refractory materials and construction technology, or strengthen the refractory material of some properties, such as stabilizer, water reducing agent, inhibitor, plasticizer, foaming agent, dispersing agent, bulking agent, antioxidant.

Q: The difference between light high alumina brick and heavy aluminum brick: High aluminum brick is one of the ideal heat insulating material, with high strength, low thermal conductivity, good insulation performance, low price and other characteristics, has been widely used in ceramic tunnel kiln, roller kiln, shuttle kiln, kiln wall, it is also used in various heating furnace coking furnace of iron and steel industry and other thermal equipment heat treatment, lining material, and has broad market prospects.

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.

Q: The difference between clay bricks and clay bricks: According to the hole rate: solid brick (no hole or hole rate less than 25% bricks), porous brick (hole rate is equal to or greater than 25%), the size of the hole is small and the number of bricks, usually used in load-bearing parts, higher strength level. Hollow brick (hole rate equal to or greater than 40%, large pore size and small amount of brick, commonly used in non load parts, low strength grade).Solid bricks and porous bricks are mostly used for load-bearing structural walls. Hollow bricks are mostly used in non load bearing structures.
