Industrial Silicon Melting Furnace 6300kva-68000kva Electric Ferroalloy Furnace
Metal Silicon Furnace (Industrial Silicon Furnace)
Our competitive Industrial Silicon Melting Furnace (6300kva-68000kva) and advanced Ferroalloy Electric Furnaces deliver superior performance for industrial applications.
Product Description
Metallic silicon, also known as crystalline silicon or industrial silicon, serves primarily as an additive for non-iron-based alloys. This industrially purified elemental silicon is essential for:
- Production of organic silicon
- Preparation of high-purity semiconductor materials
- Manufacturing special-purpose alloys
- Serving as raw material for ultrapure silicon in electronics
Additional Products
Industrial silicon production yields several byproducts with commercial applications:
- Silica powder (silica fume) - used in refractory materials and concrete
- Edge silicon
- Black silicon
- Silicon slag
Production Process
Metallic silicon is produced by reducing high-purity silica (SiO₂ content >99%) in an electric arc furnace using petroleum coke, bituminous coal, or charcoal as reducing agents. These materials serve three critical functions:
- Electrical conductivity
- Active carbon for reduction reactions
- Formation of a strong, porous hearth for efficient chemical reactions
Product Grades
Metallic silicon is classified by iron, aluminum, and calcium content into various grades including:
553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101
