Silicon Metal is a crucial industrial product that finds applications in steel-making, cast iron, aluminum (aviation, aircraft & automobile parts production), silicon optoelectronic devices, and many other industries. It is often referred to as the 'salt' of modern industries. Derived from quartz and coke through an electric heating furnace smelting process, the primary ingredient of Silicon Metal is silicon, which constitutes approximately 98%. The remaining impurities include iron, aluminum, and calcium.
Silicon Metal lump is produced in an electric heating furnace using quartz and coke. During the process, quartz undergoes a redox reaction to form molten silicon liquid. Upon cooling, it solidifies into the large silicon metal lumps we observe. Initially, these silicon metal lumps are quite large.
These large pieces are then broken down into smaller, standardized lumps. The final Silicon Metal Lumps typically range in size from 10-100mm.
Featuring a silver-gray or dark gray metallic luster, Silicon Metal boasta a high melting point, excellent heat resistance, high resistivity, and superior oxidation resistance.
1) Silicon Metal is extensively used in the refractory material and power metallurgy industries to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the field of organic silicon chemistry, industrial silicon powder serves as the fundamental raw material for the formation of high polymers in organic silicon.
3) Industrial silicon powder is transformed into monocrystalline silicon, an indispensable raw material in high-tech fields for integrated circuits and electronic components.
4) In metallurgy and foundry applications, industrial silicon powder acts as an iron base alloy additive and as an alloying agent for silicon steel, therefore improving the hardenability of steel.
5) Silicon metal plays a vital role in producing high-temperature materials.
Our main product offerings include ferromanganese, metallic silicon, silicon carbon alloy, cored wire, ferrochrome, silicon manganese alloy, silicon carbide, ferrosilicon, silicon aluminum barium calcium, and silicon barium calcium. Additionally, we are involved in the export business of refractory materials and various other metallurgical products. Products can be tailored to meet customer specifications.
The company operates a 206 cubic meter blast furnace, two 12500 kVA submerged arc furnaces, two 3600 kVA refining furnaces, four medium frequency electric furnaces, and three cladding line production lines. This setup allows for the efficient handling of manganese series hot charging and hot mixing systems, achieving a streamlined, high-quality, high-yield, and low-consumption production process.
