1.Structure of Silicon Carbide Description
Black Silicon Carbide is produced with high temperature in a electric resistant furnace from a mixture of quartz sand and petroleum coke.
Black silicon carbide is typically used for working on cast iron ,non-ferrous metals, stone, leather, rubber, and other materials which requires sharp cutting characteristics. The mineral is also used widely as a refractory material and metallurgical additive.

- Q:Would you like to know if there are any enterprises in Mianyang that need fire-resistant materials?
- Many enterprises need refractory materials. You can go to Mianyang large private enterprises to askSupermarkets, stations, hotels are required
- Q:what needs to be noted when choosing and using blast furnace fireproof materials?
- it depends on the size of the blast furnace. below 200 cubic meters alumina bricks and carbon brickcan be used. 200 cubic meters and above are currently integrated bottom, not the same as the size of the cubic level, varying in the use of refactory. I hope my answers above are helpful to you and your ideal anwers.
- Q:What is the acceptance standard of refractory?
- Feeler gauge is used to check the thickness of the refractory brickwork joint. The top of the gauge can not be sharpened. Feeler gauge is of the width of 15mm, length of 100mm and thickness of 1, 1.5, 2 or 3mm. The thickness is eligible when the depth which the feeler gauge is inserted in is less than or equal to 20mm. Ten places should be inspected per 5m2 of masonry surfaces. It is qualified when the condition in which thickness of the brickwork joint is 50% larger than a predetermined depth is not less than five times and it is excellent when the condition is no more than two times.
- Q:What's the definition of fire endurance of the fire-resistant coating for steel structure?
- Fire endurance (h): Under the condition of standard fire resistance test, the time when the building components, accessories, or structure is subjected to fire to the time when they loose stability, integrality or thermal insulation is called fire endurance which is showed in time. Steel is the kind of building material that is nonflammable with many properties of seismic resistance and bending resistance. In practical applications, steel can improve the load capacity of buildings in a relative way, meet the needs of buildings design, beauty and mould, and it can also avoid the defects of poor flexibility and tensile strength of buliding materials like concrete. Therefore, steel is quite popular in the construction industry, and it is widely used in single-story or multi-storey skyscrapers, plants, warehouses, waiting rooms and airport terminals, etc. However, as a kind of building material, it has some unavoidable defects in fire prevention. That is its mechanical properties like yield point, tensil strength and elasticity modulus will decrease dramatically with the rise of the temperature.
- Q:How to do environmental impact assessment for refractory Co., Ltd.
- The preparation of a report or statement. During the compilation process, any problems should be actively communicated with the construction side. For example, dust collector selection, environmental protection investment, total emission approval. (especially the total emission, you must let the construction side and communicate with the environmental protection bureau to get the total amount, otherwise you write the EIA does not make any sense.) Generally speaking, the preparation of the report is longer, about forty days; and the preparation of the report table is shorter, about fifteen days.
- Q:What is the function of refractory material?
- Refractory is a basic material in the field of high temperature technology. Generally, the refractory is used as structural material or lining to resist high temperature in various thermal equipment and high temperature container. In the iron and steel industry and metallurgy industry, coke ovens are mainly composed of refractory materials. Various refractories that meet the requirements are essential in blast furnace for ironmaking, hot stove, all kinds of steel-making furnaces, soaking furnace and heating furnace. Not only the die casting for molten steel needs lots of refractory materials, but also the continuous casting needs some high-quality refractory materials. Without high-quality refractory materials, external refining is also not impossible to achieve. Statistics show that the steel industry is the sector that needs the most refractory. Pyrometallurgy and thermal processing of ferrous metal also needs refractories. All high-temperature furnaces or lining in construction materials industry or other high temperature industries that produce silicate products such as glass industry, cement industry, and ceramics industry must be constructed with refractory materials. All kinds of roasting funaces, sintering funaces, heating furnaces, boilers, flues, chimneys and protective layers in chemical, power and machinery manufacturing industry need refractories. In short, when some kind of structures, devices, equipments or vessels are used under high temperature, they all should utilize refractory to resist the high temperature because those materials will deform, soften and fuse or will be eroded, scoured or broken due to the physical, chemical, mechanical effects, which may stop the operation, affect the production, contaminate processed objects and impact the quality of products.
- Q:Does anyone knows which company produces the better refractory materials?
- I recommend Xinjiang Yuanyangrefractory material Co., Ltd. Address: Near Xishan Road No.100, Saybagh District,Urumqi. Their products are both in good quality and reasonable price. In addition, there are Xinjiang Zhongwang refractory material factory, Address: Xi hongxi Road No. 769, Urumchi City. They all have a good reputation. You may think about it. 。
- Q:The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
- With the advantages of carbon refractories especially excellent slag resistance and high heat stability, but graphite under high temperature oxidation, in order to improve the oxidation resistance of carbon composite refractory materials, often adding a small amount of antioxidants, to improve the oxidation resistance of carbon composite refractories. Antioxidant additives commonly used in metal powder, silicon powder, magnesium powder, silicon carbide powder and so on.
- Q:who knows the fire resistant levels of fireproofing glass?
- Fireproofing glass is a kind of special glass which can keep its integrity in the regular fire resistance test, and it can be divided into three classes: fireproofing glass,fireproofing glass A class is a kind of fireproofing glass that can satisfy the requirements of refractory integrity, fire resistance and thermal insulation. Including composite flameproof?glass and perfusion type fireproofing glass . This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting?roof,ceiling?screen,perspective floor and other construction components demading for transparency and fireproofing. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of monolithic fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements. hope it can help you.
- Q:What is the importance of silicon powder in refractory processing?
- it depends on the type of refractory material, in addition to lS friends talked about, in the amorphous mobility\ strength should also have an impact
