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.
2.Main Features of the Calcined Bauxite
Its hardness is between that of fused alumina and synthetic diamond and mechancial intensity of it is also greater than that of fused alumina. It is brittle and very sharp and has a certain degree of electrical and heat conductivity.

- Q: Does anyone know the characteristics of refractory for glass kiln?
- Refractory is a kind of non-metallic material with refractoriness not less than 1580 ℃, which has better thermal shock resistance and chemical erosion resistance, low heat conductivity coefficient and low expansion coefficient. Refractoriness is the centigrade?temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.
- Q: Do you know what the main indicators are for the inspection of refractory materials? Thank you very much for your requests and reports
- Porosity, volume density, water absorption, true density, thermal expansion, thermal conductivity and heat capacity.
- Q: What problems should be paid attention to while using refractory materials under a controlled atmosphere?
- Pay attention to the performance of the materials, and the use of non oxide materials!
- Q: What characteristics do A grade external wall fireproofing material have?
- For characteristics of A grade external wall fireproofing material, its main raw material uses cold resistant and thermal insulated, environmental protection and energy saving material with good insulation, keeping the indoor temperature steady and making the environment more comfortable. It is several times better than other masonry in overall strength and resist capability, and it can also hang heavy objects such as air conditioners by directly nailing or installing expansion bolts. Single point hanging machine can withstand heavy objects with the weight of more than 45kg. It can also be directly fixed to the tiles, wallpaper, wooden plaques, paint, etc.
- Q: Who knows the fire rating of fire?partition with steel stud?
- 1 hour. It is in line with the fireproof test standards of national building materials . CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. It can reach up to four hours at most.
- Q: What are the features of construction class A fire resistant door ?
- Residential building: If the building height exceeds 100 meters, the combustion performance of thermal insulation material should be A level. Other civil building: Class A fireproofing material MCM should be set in buildings whose height is above 50 meters. National A level fireproof flexible?material is made up of soil, rock flour, sand, cement and other inorganic powder and modifying agent. Product density is 2327kg / m3. Upon examination, the combustion performance of the product meets A level requirements, and the additional classification meets s2, d0, t0 requirements. According to GB 8624-2006 sepcification, combustion performance of the product should reach A2-s2, d0, t0 level. Light, thin: 2-4mm thick / piece, saving space and cement, convenient to transport. : State Class A fireproof flexible?material. Freezing-thaw resistance: up to 100 freezing-thaw experiments (close to 100 years), the surface has no powder, no crack and no peeling. Aging and acid resistance: anti-aging property can reach more than 3500h, that is, it will not degenerate for 50 years. Recyclable: new energy, renewable , no "three wastes" emission
- Q: What's the classification of flameproof glass, the refractory time of fireproofing glass.
- Classify according to the structure, fireproof?performance and fire endurance of fireproofing glass. Classify according to the structure: Composite fireproofing glass (FFB) and monolithic fireproofing glass, classify according to fire resistance: thermal insulation fire-resistant glass(class A) and non-thermal insulation fire-resistant glass (class C);classify it into 5 levels according to fire endurance: 0.5 h, 1.00 h,1.50h, 2.00h, 3.00h.
- Q: I would like to know if there is any requirement for refractories in the crucible type high-frequency smelting furnace Worry！ I hope you can help me! This time!
- Good thermal stability, the crucible wall hour working temperature fluctuation is great, and the temperature field distribution is uneven, so the crucible wall will continue to produce volume expansion and contraction, resulting in cracks, which directly affect the service life of the crucible
- Q: What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?
- Hello there. Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. As for the warehouse building "category malonate", it refers to one of the fire risk of goods storage, which is divided into A, B, C, D, E, and each category is refined depending on the nature of different substances. "Malonate class" specified in article 3.1.3 of "building design for fire protection" refers to the flammable solid.
- Q: I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?
- Metallurgical industry downturn. There is fierce competition in the refractory industry.
