Silicon Metal is an indispensable industrial powerhouse, crucial for steel-making, cast iron, aluminum fabrication (including aviation, aircraft, and automobile parts), silicon optoelectronics, and numerous other industries. Often referred to as the 'salt' of modern industries, this product is derived from smelting quartz and coke in electric heating furnaces. Boasting a silicon content of approximately 98%, it contains minor impurities like iron, aluminum, and calcium.
Silicon Metal lumps are produced in electric heating furnaces using quartz and coke. The quartz undergoes a redox reaction, transforming into molten silicon liquid. Once cooled, it solidifies into the large primal silicon metal lumps.
These lumps are then broken down into smaller, standardized sizes, typically ranging from 10-100mm.
This material is silver-gray or dark gray with a metallic sheen. It features a high melting point, excellent heat resistance, high resistivity, and superior oxidation resistance.
1) Widely used in the refractory material and power metallurgy industries to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the chemical sector, industrial silicon powder serves as the foundational raw material for high-polymer organic silicon formulations.
3) Sublimated industrial silicon powder is essential in high-tech fields, particularly for producing monocrystalline silicon used in integrated circuits and electronic components.
4) In metallurgy and foundry, industrial silicon powder acts as an additive to iron-base alloys and silicon steel pharmaceuticals, improving the hardenability of steel.
5) Silicon metal is integral to the production of high-temperature materials.
Our main products 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 export refractory materials and other metallurgical products, tailoring processing to meet customer specifications.
Our facilities boast a 206 cubic meter blast furnace, two 12,500 kVA submerged arc furnaces, two 3,600 kVA refining furnaces, four medium frequency electric furnaces, and three cladding line production lines. This setup facilitates a streamlined, one-stop production process characterized by high quality, high yield, and low consumption, particularly for manganese series hot charging and hot mixing systems.
