Tung Ho Steel, Taiwan

The minimill with groundbreaking power efficiency comprises a high speed 5-strand continuous caster with the possibility to simultanously cast different section sizes. The minimill produces rebar of 9.5 to 43 mm in bar and compact coil, whereas the melt shop has a capacity 1,200,000 t/y and the  rolling capacity is 800,000 t/y. The Minimill is a best practice example for groundbreaking power efficiency. It minimizes energy consumption by directly linking the melt shop with the mill – through a temperature equalization induction heater. The results: savings of 72,000 t/y of CO2, 410 t/y of SO2 and 225 t/y of NOX emissions.
