wafer Silicon Carbide for abrasive
Specifications:
Black silicon carbide is produced at high temperature in an electric resistance type furnace with quartz sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp and sharp and heat conductivity in some degree. The abrasive made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc It is also broadly used as refractory material and metallurgical additive

- Q: Refractory material, refractory brick
- 1, according to the degree of refractoriness:Ordinary refractory material: 1580 ~ 1770 DEG CAdvanced refractory material: 1770 ~ 2000 DEG CSuperfine refractory material: >2000 DEG C2, depending on the shape and size of the product:Standard type: 230mm * 113mm * 65mm;No more than 4 measurements, (size ratio) Max:Min<4:1;Profile: no more than 2 concave, (size ratio) Max:Min<6:1;Or an acute angle of 50~70 degrees;Specific type: (size ratio) Max:Min<8:1;Or not more than 4 or a sharp angle; 30 ~ 50 degrees;Special products: crucibles, vessels, tubes, etc.3, according to manufacturing methods, refractory materials can be divided into:Fired products, unfired products, unshaped refractories4. classification according to the chemical properties of materials:Acid refractory material, neutral refractory material, basic refractory material
- Q: Application of refractory materials in petroleum industry
- Our natural gas transportation, chemicals, equipment, packing, safety, insulation, and even building materials are available.
- Q: Why does refractory need to add coarse firstly and then add fine aggregate?
- Oh, adding coarse aggregate first is to select good material to make aggregate, and the rest cna be made into fine aggregate. Because if it contains impurities, once being sintered, the appearance will be affected, but fine aggregate does not have this impact.
- Q: What refractories have good mechanical property resistance and heat expansion and cold contraction property?
- Explain that where you use it for and what requirements you have. Follow-up: I use it in metallurgical furnaces with the features of strong stirring and acidic residue.
- Q: What kind of refractory materials are used in metallurgy industry?
- Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.
- Q: Who can introduce the external wall thermal insulation materials fire rating regulations?
- 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3 combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. I feel the best insulation materials should be modified phenolic board, which can keep insulation and fireproofing, but the unit price is very expensive. Insulation materials in the domestic market have some disadvantages, it is better to considere the materials within the acceptable range in the building needs.
- Q: whether the aluminum silicate thermal insulation material is fireproof or not?
- aluminum silicate is fireproof, and the melting point is between -40 ~ 800 ℃. Aluminum: it takes the flint clay clinker as raw material, produced by resistance or electric arc furnace fusion and injection fiber-forming process. its characteristics: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.
- Q: Who knows what kind of fire protection material is better?
- Characteristic of polyurethane rigid foam thermal insulation decorative composite board: (1) ultra high cost performance, increased property's selling point (high cost performance) new model of thermal insulation material, excellent thermal insulation properties, elegant decorative effect, 50 years of service life, reduce maintenance costs and social waste. (2) it overcomes defects of traditional insulation technology (to solve the freezing and thawing, veneer cracking and shedding) traditional benzene board, the phenomenon of freezing and thawing that is easily appear in plastic extruded sheet, paint finish is easy to crack; its veneer facing can easily fall off; thermal insulation materials and wall are poorly adhered, easy off the whole. There is a themal bridge in dry hanging wall. (the characteristics of polyurethane composite board)
- Q: What refractory materials are used in power plant
- And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)
- Q: Which basic refractory is better?
- The following companies are good: 1, Xuzhou Reka Casting Material Co., Ltd. Address: No.22-2 Luoshan Road, Economic and Technological Development Zone, Xuzhou, Jiangsu. 2, Golden Triangle Refractory Plant, Xinmi, Henan. Address: Ganzhou Street, Litang Village, Xinmi City, Henan. 3, Zibo Sun Refractories Co., Ltd. Address: Wujia Village, Shangjia Town, Zichuan(Wenchang Lake) District, Zibo City, Shangdong.
