Set on 100ha of reclaimed palm oil land, Sakura is building 2 modern, energy-efficient “dual product” submerged electrical arc furnaces (SAF) in the Samalaju Industrial Park.
The plant will manufacture high carbon ferro-manganese (HCFeMn) and silicon manganese-(SiMn). One furnace will produce approximately 107,000 tons of HCFeMn per annum while the other will produce approximately 67,000 tons of SiMn per annum. Each furnace is designed to switch to either HCFeMn or SiMn giving the plant flexibility to fully produce HCFeMn or fully SiMn from both furnaces should market conditions dictate a switch in commodity.’
The smelting of HCFeMn and SiMn involves a number of process steps as outlined in the adjoining diagram.
An on-site briquetting plant processes and recycles waste, undersize raw material and product into briquettes which is used to feed back into the smelting process.
The addition of the briquetting facility in the plant is aimed at reducing the potential waste material generated by the plant by recycling the waste back into the smelting process.
Ferromanganese and ferro-alloys are essential ingredients in the production of various types of carbon, alloy steel and alloy iron. They are also used widely for the de-oxidation, de-sulphurization and refining of steel. Smaller quantities of ferro-alloys are used as reductant in order to produce other metals. A significant quantity of ferro-alloys is also consumed by the foundries and electrode industries.
