Black Silicon Carbide is brittle and sharp and has electrical and heat conductivity in some degree. Aplications : Black Silicon Carbide is suitable for make grinding wheels, cutting wheels, mounted wheels, oil stone, abrasive media, and also suitable for surface grinding, lapping or polishing. The abrasive products made of it are suitable for working on Cast Iron, Non-ferrous Metal, Rock, Leather, Rubber, Wood, Ceramic, etc. Black Silicon Carbide is also broadly used as high-grade refractory material and metallurgical additive. | |||
- Q:Who knows the refractoriness of high temperature lightweight firebricks?
- Refractoriness refractory bricks with different melting points, the melting point is liquid and solid crystal phase at a temperature equilibrium. The vast majority of bricks are made of heterogeneous materials. No fixed melting point, it begins to appear to be melting and becomes complete liquid gradually, solid and liquid coexist over a wide temperature range, fusion and softening of refractory is messured by its performance at high temperature. Therefore, refractoriness is the temperature at which the multiphase reaches a certain degree of softening. Refractoriness is an important technical indicator in evaluating refractory bricks, but it can not be seen as the temperature ceiling. GB / T 7322 "Test Methods for high alumina brick refractoriness" alumina brick refractoriness test standards. refractoriness of some commonly used refractory bricks as follows: 1, clay brick 1610? 1750 ℃ ??2,silicon brick 1690? 1730 ℃ 3, crystalline silica 1730? 1770 ℃ 4, hard paste1750? 1770 ℃ 5, high alumina brickx26gt; 1770? 2000 ℃ 6, magnesite refractory bricksx26gt; 2000 ℃ 7, dolomite refractoryx26gt; 2000 ℃
- Q:What are grades of refractory materials?
- Refractories have lots of varieties which all have different purposes.1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ to 1770 ℃, advanced refractories: 1770 ℃ to 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler.
- Q:How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?
- Fire?rating grading of external wall thermal insulation materials. 1, China's national standard GB8624-97 divides the combustion performance of building materials external insulation materials into the following grades. Level A: Incombustible materials: Almost no burning materials. Level B1: Incombustible materials: Flame-like material has good fire-retardant effect. In case of fire in the air or at high temperature, it is difficult to fire and doesn't spread quickly, and when the fire source is removed after combustion, it stops immediately. Level B2: Incombustible materials: Combustible materials have a certain flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily leads to the spread of fire, such as poles, wooden frame, wooden beams and wooden stairs,ect. Level B3 : Incombustible materials: No flame-retardant effect, hidhly flammable and high fire risk. 2, The external wall thermal insulation materials could be divided according to the fire?rating. 1) thermal insulation material that has the level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2), The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3), Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
- Q:What are the requirements of refractory temperature of refractory brick?
- Refractory brick, called refractory?brick for short, is refractory material made by firing refractory clay or other refractory raw materials. Faint?yellow or brownish, it is mainly used in building smelting furnace. It can resist 1,580 ℃ -1,770 ℃ high temperature.
- Q:What is the acceptance standard of refractory?
- It depends on the variety of materials. In general the main test items include chemical composition, refractoriness, refractoriness under load, creep, volume density, linear change, strength, slag resistance, thermal conductivity and thermal expansion. If it is shaped products, it is required to inspect the size deviation and whether it has edge. Detection method accords with the relevant national standards and there are lots of them. You can refer to the standard compilation.
- Q:What a blast furnace refractories generally?
- refractories for blast furnace include carbon brick and silicon-aluminum refractory. BF carbon brick inlcudes half-carbon charcoal bricks, microporous charcoal brick, ultra porous charcoal bricks, graphitic brick and mould pressing charcoal brick. tiles and molded graphite small charcoal bricks. I hope my answers above are helpful to you and your ideal anwers.
- Q:Who knows how many poured refactory material are there?
- Casting refractory material, refractory material used often are AZS brick, corundum brick, direct bonding magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide brick, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide and other refractory materials.
- Q:Can quantitative feeder be used in refractory plant? Thank you
- Feeder experts, justice and analysis, quantitative feeder, of course, can be used in refractory plants
- Q:How to apply the alumina powder on refractories?
- What kind of the refractories can make the aluminium oxide increase the aluminum content and specific gravity, and erosion-resistant.
- Q:How is the performance of refractory materials?
- It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project
