A technological breakthrough in transverse flux heating
CELES EcoTransFlux™ transverse flux induction heating technology is a breakthrough for heating nonmagnetic steel strips at extremely high temperatures with superior efficiency.
The power, flexibility and compact design of CELES EcoTransFlux™makes it a technological solution that meets requirements to optimize existing or planned processing lines.
Most importantly, the technology can help develop an application for stainless or carbon steel lines to quickly heat metal strips at very high temperatures in a non-oxidizing atmosphere.
In the stainless steel treatment process, CELES EcoTransFlux™ eliminates a chemical treatment phase for strips during the rolling process, thereby reducing harmful emissions and acid waste.
The ideal solution for the steel industry: CELES EcoTransFlux™
Gas or electrical resistance is typically used to heat steel strips during continuous annealing. These technologies heat slowly at about 70°C/second, have low thermal efficiency levels of around 50%, and produce NOX or CO2 emissions.
After years of research and development in conjunction with EDF and Usinor and with support from the Ademe and the French Ministry of Industry, Fives is now able to offer a high-density inductor that meets the special requirements of the steel industry:
- Metal heating at temperatures above the Curie point (760°C) with over 3 MW of inductor-injected power in the steel strip
- A quick-response heating system with low thermal inertia for extremely rapid temperature increases
- Thermal efficiency above 75%
- Patented electromagnetic devices and coils that provide temperature consistency of +/-10°C
The project was co-funded by the European Union's Life+ Program to encourage advances in innovative technologies with minimum environmental impact.
