Description:
Silicon Carbide is produced by melting a mixture of silica sand and cokes in ultra high power electric furnaces. Silicon Carbide is chemically stable and has high corrosion resistance, which makes it hard to corrode from exposure to alkali or acid. Silicon carbide is also characterized by its high hardness, outstanding heat resistance, low thermal expansion, resistance to chemical reaction, and ability to function as a semiconductor.
Application:
SiC is suitable for cupola and electric furnace, widely used in iron foundries and in steel mills as deoxidizing agent, especially in ladle furnaces and electric arc furnaces during slag treatment. Silicon carbide can improve the temperature of molten steel rapidly, shorten the melting time, play the role of deoxidizing, increasing carbon and silicon, heating to improve the quality of steel.
Feature:
Black SiC, dissolved in a basic oxygen furnace used for making steel, acts as a fuel.
1.Additional energy liberated allows the furnace to process more scrap with the same charge of hot metal.
2.Silicon Carbide can also be used to raise temperatures and adjust the carbon and silicon content.
3.Silicon carbide / SiC can reduce the cost of production, produce cleaner steel and lower emissions.
Chemical Composition
- Q: Fire rating of decoration materials
- All light steel keel gypsum board is considered level A; if the wood finishes up to B2 grade fire rating depends on the proportion of the use of wood veneer and the proportion of this wood veneer fire grade, if the proportion of wood veneer is small,it can be considered level A
- Q: Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
- Add some hair and slags, or it will crack before calcination.
- Q: Why do magnesium oxide refractory bricks can be made into refractories?
- Because the magnesium oxide, commonly known as magnesia, which is a basic oxide, with the common property of alkali oxides and belongs to the cementitious material . It is white or light yellow powder, odorless, tasteless, non-toxic and a typical of alkaline earth metal oxide, whose chemical formula is MgO. It is white powder, with melting point of 2852 ℃, boiling point of 3600 ℃ and relative density of 3.58 (25 ℃). The magnesium oxide that is soluble in acid and ammonium hydroxide solution has high insulation properity. After high temperature of above 1000 ℃ burning, it will transform into crystals, and when rising above 1500 ℃ , it will turn into dead-burned magnesium oxide (also known as the magnesia) or sintered magnesia. So the performance of magnesium oxide refractory bricks is good, and the fire resistance of it is very strong.
- Q: How to choose refractory material
- The crystalline refractory fiber mainly consists of polycrystalline mullite fiber, the optimum use temperature is 1300 DEG C, and the long-term use temperature of polycrystalline alumina fiber is 1400 DEG C. The service temperature of ordinary refractory fiber is 1150 degrees, and the use temperature of advanced refractory fibers (such as alumina, zirconia, refractory fiber) can reach 1700 degrees centigrade
- Q: Who knows about the grade C fireproof door materials?
- grade C fireproof door materials: 1. the doorframe raw materials of grade C fireproof doors: the galvanized?steel?sheet is no less than 1.2 mm(the thickness of steel plate is no less than 1.5 mm when the height and width of doors are more than 2.1 m and 1.2 m respectively). 2. the door leaf raw materials of grade C fireproof doors: the thickness of galvanized?steel?sheets is no less than 0.8 mm. 3. the reinforcement raw materials of grade C fireproof doors: the thick?steel?plate is no less than 1.2 mm, if there are bolt-holes, the thickness of which is no less than 3.0 mm. 4. filler: The fireproofing filling materials that fit the environmental and standard needs(for instance, door leafs are filled with perlite fireproof materials inside, and doorframes are filled with fire-resistant cement) meet the test criterion promulgated by the relevant state departments. 5, the sealing requirements: there are seal grooves in doorframes and within which are embedded with refractories.
- Q: what's the varieties of thermal insulation material with A level fire?rating?
- Inorganic thermal insulation material can do it, such as glass wool,rock wool,foam glass,etc. phenolic foam materials in organic foam material is special. phenolic foam not only has good thermal insulation properties but also can be composited with steel plate and other materials, A class thermal insulation materials that reach A class combustion performance include: rock (mine) wool, foam glass, EVB, etc. thermal insulation materials with A class combustion performance mainly include: phenolic aldehyde,gelatine powder polyphenyl granule, etc. thermal insulation material of fire barrier zone can use rock (mine) wool, foam glass, EVB and other materials with A class combustion performance.
- Q: Can anyone tell me which materials are fire-proof high temperature resistant material?
- Fireproof high temperature resistant materials such as: Quartz, tridymite, cristobalite, chalcedony, flint, opal, quartzite, White silica sand, diatomaceous earth, the silicon oxide (SiO2) contained in these siliceous materials is at least 90% . The silicon oxide in some pure raw material can be above 99 %. Siliceous materials are acidic in high-temperature chemokinesis. when existing metallic oxide or contact with metallic oxide, they will conduct chemical actions and conbine into fusible silicates. Therefore, if the siliceous raw material contains a small amount of metal oxide, its heat resistance will be seriously affected..
- Q: what is the specs of thermal insulation refractory slab ?
- According to different requirements of each project to select the fire board. fireproof?panel should have product qualification certificate. Specifications shall comply with the requirements of design drawings and inspection reports from the National Fireproofing Protection Building Materials Inspection Center. General specifications are as follows: Length: it is determined according to the project width: 1200mm, 900mm; thickness: 9.5mm, 12mm, 15mm, 18mm, 25mm. Commonly used is 12mm. According to different requirements of each project to select the fire board. Fireproof?panel should have product qualification certificate. Specifications shall comply with the requirements of design drawings and inspection reports from the National Fireproofing Protection Building Materials Inspection Center.

- Q: What is the the best ratio of mortar in refractory cement?
- The ratio of refractory cement are: M10 the ratio of cement and mortar: cement: Sand= 346kg: 1631kg M7.5 ratio of cement and mortar: cement: Sand =274kg: 1631kg M5 The mix proportion of cement and mortar: cement: Sand = 209kg: 1631kg M10 mix proportion of composite mortar: cement: Sand: Lime =306kg: 1600kg: 29kg M7.5 mix proportion of composite mortar: cement: Sand: Lime =216kg: 1600kg: 64kg M5 The mix proportion of composite mortar: cement: Sand: Lime =205kg: 1600kg: 100kg
