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:How to divide the materials according to the National Fireproofing Material Standard?
Each country has its own fire safety standards, I do not know which country's standard do you want to know, and each country of fireproof material to the division level is not the same. GB GB 8624, the German standard DIN 4102-1, the British standard BS 476, French standard NF P92 -501 and so on. GB 8624 is Chinese building materials and grade of combustion performance. The information coming form fire resources network (FireTC.
Q:What are the additives and recipes of refractory?
You can try FDN.
Q:What are the requirements of refractory temperature of refractory brick?
Refractoriness can reach 1690 degree, but the highest operating temperature is 1350 degree. If the temperature goes higher, operation life will be greatly shortened.
Q:How is refractory material made?
It is made by mixing and processing of various refractories.
Q:What is the limit of fireproof rolling shutter?
Fire proof door can be divided into Serie A, B and C in terms of fire endurance limit, fire resisting limit are not should be less than 1.20h, 0.90h and 0.60h. Set firewall has difficult sites can use fire shutter fire partition separating, when the back fire surface temperature rise refractory limit determination conditions of fire shutter, the fire resistant limit not less than 3H; when employed does not include back fire surface temperature rise do fireproof limit determination conditions of fireproof rolling curtain, on both sides of the shutter should be set up a separate closed type automatic water spraying system protection, sprinkler system continuation of time should not be less than three hours.
Q:Current development status of qualitative refractory materials.
Q:What occupational hazards should be detected in glass ceramic and refractories industry?
Q:What's the heat conductivity coefficient of fire-resistant material?
The heat conductivity coefficient of fire resistant material is related to bulk density and mainly related to the internal structure. Different materials have different structure and thermal conductivity and temperature . Carbonaceous material can be used for heat dissipation and reach more than 15. For thermal insulation it can be 0.00.
Q:I wanna ask what are the acidic refractories?
(1) silica brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity.
Q:The difference between refractory and thermal insulation material
Refractory refers to inorganic non-metallic material, whose refractoriness is not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulated material also belongs to refractory as long as its refractoriness is higher than 1,580℃.
