Product Description:

High Grade Refractory Material/SiC Powder--Black Silicon Carbide  97

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 Silicon Carbide

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.

3.Main usage of the Silicon Carbide

1.Grinding non-ferrous materials, rock, stone, leather, rubber, finishing tough and hard materials

2.Bonded abrasive tools, lapping and polishing

3.Widely used as a metallurgical additive and refractory material

4.Refractory

Q:what's the materials of fireproof housing?
I'm very glad to answer for you. 1. Mobile homes in high-rise buildings, as for the interior hidden artifacts of single and multi-layer mobile homes, when its fire endurance is ruled above 1.5 h, you should choose the non-swelling large activity fire retardant coating; 2.as for Indoor mobile house, light roof mobile house and mobile house need to be decorated, when its fireproof limit is ruled under 1.5 h, you can choose swelling mobile house fire retardant coating; 3. The fire endurance of mobile houses need to be above 1.5 h, outdoor mobile houses project shoule better not choose swelling fire retardant coating. 4. Indoor mobile houses extremly need to be decorated, hot standby is a living place of mobile houses, bearing steel structure of equipment, bracket, the part easy to be knocked like skirt, its fire endurance needs to be above 1.5 h, you better choose fireproof panel of mobile houses. 5. Open mobile houses, you should choose fire retardant coating of mobile houses suitable for outdoor, and use the coating with over one-year outdoor mobile houses project operation and the coating function without significant changes. 6. multiple layer coating should be matched with each other, the bottom layer coating should be able to be used with rust-proof paint together or have rust-proof function. 7, while choosing the fire retardant coating for special function, it should have over one-year project operation and verification case and matched fire-proof function.
Q:Can anyone say something about what A-level fire-proof decorative material is?
The major products are material monomer A-level and composite A-level, now a lot of B-level material is wrapped in calcium silicate board. The foam cement overall composite is level A, such as phenolic aldehyde composite, as well as some of the foam paddings, monomer A-level includes rock wool, ultra-thin insulation panel and the like. But there are few products with real sound A level qualification. Many manufacturers are playing the edge ball with A-level fire rating examining reports and B-level system detection reports and records, but this situation will not last long, which will soon be clear.
Q:How long is the fire resistant limit for ultra thin fire retardant coating?
The fire resistant limit of ultra-thin fire retardant coating is 1.5 hours, generally fire resisting time for thin fire retardant coatings does not exceed 1.5 hours. If the time exceeds 1.5 hours, thick fire resistive coating should be uesd. There is no detailed stipulation for ultra-thin fire retardant coating, and the thickness of the inside is the fire resistance limit shall reach certain time(at least). If fire resistance limit is 2.5 hours, the thickness shall be 4.9mm. If the fire resistance limit is 2 hours, the thickness is 3.5mm. If fire resistance limit is 1.5 hour, the thickness should be 1.75mm.
Q:Who knows about the fire endurance of sintered shaly hollow bricks?
Sintered shaly hollow bricks of Chu area have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance. The fire endurance of sintered shaly hollow bricks should not exceed1050 degrees otherwise they will burn excessively. I, actually, think that the temperature should be controlled within 980 degrees. I hope my answer may help you.
Q:What's the fire retardant material of roller shutter fire resistance door ?
Fire resistant rolling shutter door is generally filled with aluminum silicate fiber cotton inside.
Q:Who knows that among refractory materials, insulation boards from which refractory material industry is superior in quality?
Using high temperature insulation material during casting process .In the molding, assembly the insulation board on the ingot head or install heat insulation cap . There are three ways to install the molded steel insulation board and install insulation board on at the head of the ingot, namely, clamping, nail fixation and mosaic technique.Compared with clay-based liner, the use of insulating board will improve high steel billet rate up to about 5% to 10%.
Q:What is high alumina refractory?
It refers to inorganic non-metallic material with refractoriness of higher than 1580℃. Refractoriness refers to the celsius temperature that the cone-shaped refractory sample without load can resist, and under which the sample won't soften and melt down. Refractory material appears together with high temperature technology, and roughly dates from the Middle Bronze age. In the Eastern Han Dynasty (AD25~AD220) of China, fireclay refractories has been used as furnace refractories and saggers for making porcelains. In the early 20th century, refractory material develops toward the direction of high purity, high dense and ultra high temperature products, and meanwhile unshaped refractory and refractory fiber with no need of firing at all and with low energy consumption appear.
Q:what's the classification of fireproof and thermal inuslation matertial?
1. thermal insulation material with A class combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite (2) thermal insulation material with B class combustion performance: extruded polystyrene board after special processing (XPS)/ polyurethane after special processing (PU) , phenolic aldehyde, gelatine powder polyphenyl granule. 3,thermal insulation material with B2 class combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane (PU), polyethylene (PE),etc. sea capacity module and vitrified micro bead(cooperate with the innovator of vitrified micro bead, Liu Weihua) fireproofing issues have been completely solved.
Q:How much is the duration of fire resistance of the porous brick shale?
It’s said on the internet that 950℃ is moderate and don’t exceed 1100℃, or the bricks are inclined to be melted.
Q:What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
You mean furnace lining or ladle lining? Generally magnesia is used as furnace lining, but heat preservation should be practiced when shut down, or brasque would crack. Surly you can employ existing furnace lining which is sold in Tianjin, a little bit expensive, the average lining could be used for 300 furnaces. The furnaces made by magnesia myself break down after 40 furnace were finished. What I referred is a furnace weighing 2 tons, as for a bigger furnace, the existing brasque would be OK. What is the difference between furnace lining and ladle lining? Can you give me more detail about the materials of making a furnace weighing 2 ton? Why others can burn 80-90 furnace with 0.7-ton furnace; over 200 furnaces with 2 ton? What are these ingredients? What I know is just magnesia, magnesium borate, and together with boric acid, they also have many types, which one should I use? Thank you!
