Grinding Black Silicon Carbide
Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. It is used for making bonded and coated abrasive tools, grinding metal and non-metal materials of lower tensile strength, such as gray cast iron yellow bronze,aluminum, stone, leather, rubber, etc.

- Q: What are some of the new refractories and what are their characteristics?
- Refractory common AZS refractories are often used brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, beryllium oxide and other refractory materials, Magnesium Oxide
- Q: Which industry does refractory belong to? Does it belong to construction industry?
- I am engaged in construction. Refractory material does not necessarily belong to construction industry. Fire resistance is only a part of material?performance. Indeed, there are many places requiring refractory accorded with fire resistant level.
- Q: What are the standards of refractory concrete ?
- Heat-resistant concrete refers to the kind of concrete which remain undamaged, do not lose the necessary bearing capacity at 200 ~ 1300 ℃ high temperature for long term, and still maintain its physical and mechanical properties.
- Q: Which schools are the best schools in the world for learning knowledge about refractories?
- Wish it helps you out.
- Q: What are the technical requirements for refractories?
- The range of refractory is too broad. Therefore it is difficult to answer this question, but it is certain that there should be technical requirements.
- Q: How many fire endurance grades are the AAA fire resisting shutter divided?
- The fire shutter is divided into A / B / C classes. The refractory limits are not less than 1.2 /0.9 /0.6 hours. References to "general technical specification for steel fire resistance rolling shutter door GB 14102-93". 4.3 4.3.1 Classification according to fire resistance time. The common steel fire resisting shutter(see Table 3) The categories of the codes of the refractory time hF1 1.5F2 2.04.3.2 composite steel fire shutter composite steel fire shutter(see Table 4). Table 4 and Category Code refractory time hF3 2.5F4 3.04.4 refractory press time, smoke performance classification 4.4.1 ordinary steel fire anti-cigarette curtain (see Table 5) Table 5 and category code leak smoke refractory time h (20Pa pressure) FY1 1.5 ≤0.2m3 / m minFY2 2.0 ≤0.2m3 / m min4.4.2 composite steel fire anti-cigarette curtain (see table 6) table 6 and category code leak smoke refractory time h (20Pa pressure) FY3 2.5 ≤0.2m3 / m minFY4 3.0 ≤0.2m3 / m min excerpt complete fire shutter when the fire district for fire resistance of 3 hours, the opening portion on the firewall setting fire shutter fire resistance of 1.2 hours. **** Fire resistance of 3.0 hours called premium (fire back surface). "Construction Regulation" is mentioned in setting up a firewall and used as the separation of the fire resisting shutter and the fire?compartments. When taking the fire back surface temperature rise as the fire resistance standard of the fire resisting shutter, the fire endurance should not be less than 3.00h; When taking the fire back surface temperature rise as the fire resistance standard of the fire resisting shutter, the two sides of the roll should have protection of ?closed automatic water spray system, and the duration of water spray system should not less than 3.00h. In summary: The fire resisting shutter can be divided into: Grade, A, B and C looking to adopt
- Q: What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?
- Level B1: building materials with flame retardancy: this kinds of materials have good effect in flame retardation. Under the case of open fire or high temperature, it is not easy to be ignited and spread quickly, and when the fire source is removed, fire would stop immediately. Level B2: combustible building materials: combustible building materials also have effect in flame retardation. It will get burnt as soon as it meets open fire or high temperature, so it can easily give rise to rampant fire, such as wooden pillars, wood roof trusses and wooden stairs.
- Q: What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
- Now cone crusher is generally used.
- Q: What are the characteristics of clay refractory materials?
- Clay refractory has excellent performance in anti fatigue. The fatigue strength of the general metal is 50% ~ 40 of the tensile strength, and some composite materials can be as high as 70 ~ 80%. The fatigue fracture of the composite is from the matrix, which is gradually extended to the interface between the fiber and the matrix. Therefore, the composite material has omen before destruction, and it can be checked and remedied. Fiber composite material also has good performance in anti vibration fatigue. The fatigue life of The helicopter rotor made of composite material is longer that made of metal. I hope my answer will help you!
- Q: What level is the rock wool board fireproofing material ?
- The fire rating classification is a provision for all insulation materials, rather than to separately divide rock wool. Determine the value of the material fire rating according to the relevant test items of 8624. As the rock wool is made from basalt fusion, so it is the level A non-combustible material.
