Black Silicon Carbide is brittle and sharp and has electrical and heat conductivity in some degree. Aplications : Black Silicon Carbide is suitable for make grinding wheels, cutting wheels, mounted wheels, oil stone, abrasive media, and also suitable for surface grinding, lapping or polishing. The abrasive products made of it are suitable for working on Cast Iron, Non-ferrous Metal, Rock, Leather, Rubber, Wood, Ceramic, etc. Black Silicon Carbide is also broadly used as high-grade refractory material and metallurgical additive.

High Quality Metallurgical Grade Black Silicon Carbide

Q: What are the materials of white firebricks?: The commonly-used firebricks include alumina bricks, corundum bricks, chamotte bricks, high alumina bricks, diatomite bricks, zircon bricks, lightweight corundum bricks, zirconia bubble bricks and so on ~~~

Q: How many kinds of fireproof materials are there in the market?: A-level materials are the best which will not burn while the B-level materials are made of combustible materials which can burst into flames.

Q: What are the specifications of fire resistant bag?: Currently there are four specifications: C10, C40, B40 and B50 suitable for steel ladle of less than 60 tons. I hope it can help you.

Q: What is the function of refractory in ceramics?: It depends on what purpose you want to achieve. At the same time, part of special ceramics belongs to refractory. If is is to produce ceramic products, the aforesaid answers are very comprehensive.

Q: How many refractory materials does the annual output of 1 million tons of coke oven require?: The production of dense synthetic Magnesium Oxide requires many steps, briefly summarized as follows:(1) Mgcl2+Ca, Mg (OH) 2, =Mg (OH) 2+CaCl2Sea salt or brine, dolomite, magnesium hydroxide, residual salt(2) Mg (OH) 2 Mg0 (low density);(3) MgO, Mgo (compact)The resulting compact Magnesium Oxide generally has a purity of up to 95%-99%, depending on the manufacturing process and the final application requirements. As shown above, Magnesium Oxide can be obtained from sea water and slaked lime. The density of the final product is through the high temperature roasting in shaft furnace and the large area obtained by calcination, and the mechanical compaction. Through the pre sintered refractory material to fundamentally eliminate the permanent contraction or extension is extremely important, it is obviously, because we cannot expect excessive contraction or extension in the use of the materials can be used to store the proper degree of molten metal or slag. The production of magnesium oxygen throughout the world (Fang Meishi) large factories in the United States, Michigan by brine well production, and by the sea water production Magnesium Oxide factory is located in Florida, Texas, California and Maryland.

Q: What are the application of old refractory bricks?: It can be used for refractory bricks again, as long as the quality is good. It is much more cost-effective than Bayerite.

Q: What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?: You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into

Q: Which refractory is better for building 1500 degree kiln ?: High alumina brick or 99 alumina hollow ball brick is OK, which can withstand a temperature of 1600 ℃.

Q: What are the refractories for converter?: Analysis of refractories are as follows: MgO-C brick converter Dongxin refractory furnace cap, steel tapping hole, shaft, shaft, pool, air brick
