Utilisation du carbure de silicium

Silicon carbide is an outstanding nonoxide ceramic material with exceptional properties. Particularly hard, silicon carbide makes an ideal material for making wear-resistant components or abrasives.

It also offers excellent corrosion resistance and can operate safely for extended periods in acid, alkali and oxidative environments. Furthermore, its high temperature performance makes it suitable for use in molten metal furnaces and other heating equipment.

Basic Oxygen Furnace

Silicon carbide is known for being highly corrosion resistant and boasts a Mohs hardness rating of 9. It also exhibits superior wear resistance, making it an excellent choice for applications that operate under severe environmental conditions. Furthermore, silicon carbide also acts as an electrical insulator.

The basic oxygen furnace, also referred to as Linz-Donawitz steelmaking process or oxygen converter steelmaking, accounts for 67% of global crude steel production. This technique utilizes oxygen being blown into molten pig iron in a refractory lined vessel in order to oxidize it and make crude steel.

Modern steel plants typically utilize the basic oxygen furnace process, in which molten iron is mixed with pure oxygen to make steel quickly and efficiently. A multi-nozzle lance blows this pure oxygen over the converter’s converter chamber and converts into exothermic heat, melting away carbon deposits while simultaneously forming steel suitable for various uses.

Steel Plant

Steel plants are large integrated facilities that typically cost $1 billion to $4 billion to construct and operate, producing various finished products such as heavy plates and pipes as well as rails and bars with annual production capacities exceeding 2,000,000 tons per annum.

Integrated mills typically consist of coke ovens and coal chemical plant, sinter plant, blast furnace, steel melt shop and rolling mills. The blast furnace converts iron ore into liquid steel which can then be cast into various shapes.

Scheduling the manufacturing process at a steel plant involves understanding all of its procedures. If upstream procedures cannot collaborate effectively with downstream ones, equipment and human resources could become wasted; true optimization capabilities that span traditional system boundaries may provide the solution to this challenge. Energy intensity has decreased considerably in this industry over the last fifteen years.

Chemical Industry

Silicon carbide is one of the hardest substances known, boasting an Mohs hardness scale rating comparable to diamond. As such, it has many uses in abrasive machining applications due to its excellent resistance against wear. Furthermore, silicon carbide exhibits outstanding corrosion resistance properties as it maintains its strength even up to 2700degC temperatures.

Chemical processing environments often expose metals to acids, alkalis and other damaging agents; additionally it has excellent thermal conductivity and low coefficient of expansion rates for added reliability.

Carborundum can be doped with either phosphorus or nitrogen to produce an n-type semiconductor, and beryllium, boron, aluminum and gallium for p-type doping. With its wide bandgap that enables more efficient electrical energy transfer than traditional semiconductors such as silicon or germanium semiconductors – making it suitable for power electronics like DC/DC converters for electric vehicle charging systems; LED manufacturing as well as gemstone cutting/polishing applications. Carborundum itself can sometimes even used as a gemstone!

Automotive Industry

Silicon carbide plays a pivotal role in automotive production and offers multiple advantages that help lower energy usage and power bills. Silicon carbide offers significant potential savings across an industry which faces such dramatic change as it plays its part.

Silicon carbide (SiC) is an extremely hard and durable synthetically produced crystalline compound made of silicon and carbon, typically available as sintered material and produced through various techniques such as recrystallization, hot pressing, microwave sintering, reaction sintering or pressureless sintering. Silicon carbide serves an important purpose as an abrasive material and can be found in grinding wheels, cutting tools and sandpaper products.

Silicon Carbide boasts exceptional electrical properties due to its semiconductor nature. This material’s resistance against organic and inorganic acids, salts and alkalis is superior to many of their counterparts with resistances up to seven orders of magnitude difference; making this insulating material suitable for applications like traction inverters for electric vehicles as well as DC/DC converters for energy storage systems.
