| Abstract Scope |
Ferrochrome, an essential component for the metallurgical sector, is used in stainless steel manufacture, with high-carbon ferrochrome (HC FeCr) being the most common kind. Traditional carbothermic reduction techniques have considerable environmental issues due to high temperatures and significant energy usage. Each ton of HC FeCr made this way releases 4.7 to 6.1 tons of CO₂ equivalent greenhouse gases, and it uses between 40 to 59 GJ of energy per ton, mostly during the smelting stage. Therefore, the type of electrical power source used in the production process directly determines the environmental impact. The study covers at how hydrogen (H₂) and methane (CH₄) gases affect the reduction process, checks how metallic phases and chromium carbides are formed, and examines factors like temperature, gas mixture, and reaction time. The aim is to develop low-emission production conditions and contribute to sustainable metallurgy applications. |
