CMT® technology
Induction heating
Our CMT® technology eliminates the need for handling and reheating by linking the caster to the mill. An induction heater gives you perfect control of the starting temperature for the rolling mill – according to the billet speed. Using CMT® technology means no foundation works in the furnace area and no billet storage are necessary. Environmental aspects are demonstrated by the Tung Ho reference plant:
- Savings of 72,000 t/y of CO2 emissions
- Savings of 410 t/y of SO2 emissions
- Savings of 225 t/y of NOx emissions
