CELES EcoTransFlux™: high-flux induction for advanced steel
The clear industry focus is cost savings, energy consumption and pollutant reduction with high expectations on quality, reliability and safety. Fives’ breakthrough induction heating technology, CELES EcoTransFlux™, was designed in cooperation with the EU’s Life+ Program to meet the challenging demands of steel processing quality and production needs.
CELES EcoTransFlux™ is high power Transverse Flux Induction Heating (TFIH) technology that allows optimization of steel grade metallurgical properties and reduced greenhouse gas emissions and acid wastes. It primarily functions as a booster or annealing device on carbon steel annealing and galvanizing lines (CAL / CGL / CAGL, etc.), stainless steel processing lines (CAPL /BAL / I-BAL, etc.), and silicon steel lines (DCL / APL / SACL, etc.).
CELES EcoTransFlux™ heats magnetic and nonmagnetic steel strips at extremely high speeds and temperatures with superior efficiency. As it heats metal strips in a non-oxidizing atmosphere, it results in a significant reduction in NOx and CO emissions.
Further features include:
- Metal heating above the Curie point with over 3 MW of injected power in the steel strip.
- A quick-response system with direct transfer of energy (on/off concept) and low thermal inertia
- Patented conductors allowing thermal efficiency above 75% regardless of strip format
- Patented design providing homogeneous temperature of +/-10˚C or better
- A versatile, compact and economical solution
In order to meet annealing process criteria for new automotive steel grades, CELES EcoTransFlux™ is designed for rapid heating cycles:
- Higher heating density with 2MW/m2 of steel strip
- Higher treatment temperature above 900°C
- Higher temperature increase up to 400°C/s
Direct benefits for a final product include improved mechanical resistance (+5-10%) and elongation capability preservation.
Recently, CELES EcoTransFlux™ systems, dedicated to production of advanced and ultra high-strength steels (AHSS/UHSS) have been supplied to major steel producers in Asia and North America, respectively.
