Silicon (Keiso) Refining Worker (Metallic Silicon)
けいそせいせいこう
Industry & Occupation
Classification
Summary
A manufacturing technician who reduces and refines silica stone, the raw material for metallic silicon, using electric furnaces and other equipment to produce high-purity metallic silicon.
Description
Silicon refining workers are responsible for the process of using silica stone (silica) as raw material, employing electric arc furnaces or reduction furnaces, and removing oxygen through carbon reduction reactions to produce metallic silicon. They handle the entire process from raw material charging, temperature control, tapping of molten metal, slag removal, casting, crushing, particle size classification, to packaging. They measure the chemical composition and purity of products using analytical instruments, and perform adjustments and record management to maintain quality standards. Work in high-temperature environments and handling of heavy objects are common, making inspection of safety devices and wearing of protective gear essential. Equipment maintenance, troubleshooting, and improvement proposals are also part of the job duties.
Future Outlook
Due to the expansion of renewable energy and the semiconductor industry, demand for high-purity metallic silicon will remain stable in the future. Energy-saving in manufacturing processes and technologies to reduce environmental impact will be key.
