Metal silicon project EPC
Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-iron-based alloys.
Metallic silicon (Si) is industrially purified elemental silicon. It is mainly used to produce organic silicon, prepare high-purity semiconductor materials, and prepare alloys for special purposes. It is also the raw material for ultrapure silicon in the electronics industry. Additional products of industrial silicon: including silica powder, edge silicon, black silicon, silicon slag, etc. Among them, silica powder is also called silica fume, microsilica fume or silica fume. It is widely used in the refractory materials and concrete industries.
Metallic silicon is produced by reducing silica (SiO2 content greater than 99%) in an electric arc furnace. The reducing agents used are petroleum coke, bituminous coal, charcoal, etc., which have three functions: ① conduct electricity; ② serve as active carbon to complete the reduction reaction; ③ create a strong and porous hearth to complete the chemical reaction quickly.
According to the content of iron, aluminum, and calcium in metallic silicon, metallic silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101.
Based on our rich practical experience in the field of ferroalloy smelting and the safe operation record of more than 200 submerged arc furnaces around the world, we provide customers with a complete set of metallic silicon solutions. The submerged arc furnace specifications include 6300KVA, 12500KVA, 16500KVA, 22500KVA, 33000KVA, 55000KVA, 68000KVA, etc., from process design to equipment production, debugging and installation, production operation, we have accumulated a reputation that satisfies customers. Provide comprehensive support from raw material grades entering the furnace, raw material sintering, batching system, furnace area equipment (submerged arc furnace, ferroalloy refining furnace, etc.), tapping system, finished product finishing, dust removal system to cooling system, etc., including engineering consulting; engineering And equipment design; equipment system integration; material and equipment supply; EPC general contracting; process management services and training; project management; production and operation services and other comprehensive services throughout the entire business chain.
