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 long is the duration of fire resistance that fireproof door of level B can endure?
According to the duration of fire resistance, fireproof doors can be divided into three levels, namely level A,B,C. And accordingly, the duration of fire resistance of them should not lower than 1.20h, 0.90h and 0.60h. Fireproof door, a door that can meet the requirements of fire resistance stability, fireproof door integrity and thermal insulation at a certain time, is a fireproof separator which is located in fireproof partition, emergency staircase and vertical silo. Apart from functioning as a common door, a fireproof can also prevent the spread of fire and smoke in a certain period to make sure that people are safely evacuated.
Q:What are the refractory materials above 1000℃
I have no idea what field you are in, and I am skillful at making refractory materials, because this is my job. You can send me an email informing your purpose, here is my email address sihouzm@yeah.net.
Q:How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?
I feel the concrete thickness should depend on the experience and the actual situation. As for the specific method, I also can't say too accurately. If it's ladle, it generally chooses alumina magnesia castable.
Q:How to prolong the furnace age of Induction furnace by using fireproof materials?
magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.
Q:What are the components of refractory clay?
The major raw material are bauxite, magnesite, silica, etc. It is easy to combine, high temperature resistant, corrosion resistant and has other advantages. It can be applied for refractory bricks in a variety of masonry.
Q:What are the new refractories?
There are many of them. We can talk face to face. Sichuan Province Deyang City Xinxin Refractories Co. 0838-2228543
Q:What is the material of fire resistant glass reinforced plastics grating?
What is the material of fire resistant glass reinforced plastics grating?
Q:How should refractory cement be used?
Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will generate a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees.
Q:what's the varieties of fire-proof sealing material?
Fire blocking material currently on the market include: fire stopping board, foam blocking material, flame resisting module, fire-resisting sealant, flexible organic caulking, WXY-II and fire retardant bag, etc. fire-proof sealing material is widely used in building construction and can ensure high-temperature flame and smoke from fires not spread to another fire compartment, different buildings generally use different sealing methods. Pipeline is generaly sealed by pouring concrete board or mortar.
Q:What parts of cement kilns are refractories used on?
Generally they are used in cyclone, feed pipe, and duct and refractories are high-strength alkali-resistant castable, calcium silicate board, high-strength alkali-resistant brick, dome-shaped alkali resistant brick. Refractories in smoke chamber are high-alumina refractory castable, anti-skinning pouring material and calcium silicate board. Refractories in duct are high-strength alkali-resistant bricks, calcium silicate boards and steel fiber reinforced castable. Refractories in hooding parts of kiln are high strength castable high alumina and calcium silicate board. Refractories in rotary kiln are phosphate bonded high alumina brick, silmo brick, magnesia chrome brick, steel fiber reinforced castable. Refractories in grate cooler are vault alkali brick, high alumina refractory castable, steel fiber reinforced castable and calcium silicate board. Refractory in coal burner is dedicated castable for coal burner.
