 HICON/H2Q®CAL continuous annealing line

The first 100% H2continuous annealing line for automotive steels with H2 jet quench

EBNER's reputation as the most innovative and competitive full-solution provider has been underlined yet again with this worldwide innovation: a continuous annealing line with 100% hydrogen atmosphere and 100% hydrogen quench instead of a water quench. The facility has 20 times the throughput of a conventional hardening and tempering line for carbon steels, along with improved quality, increased flexibility and a larger range of strip dimensions. The horizontal version achieves a throughput of 18 t/h, with even higher throughputs possible using our vertical design.

The HICON/H2Q® CAL continuous annealing line, with its state-of-the-art quench, can process AHSS grades including DP, TRIP, martensitic, Q&P and other grades from 580 - 1700 MPa yield strength with incomparable flatness.

In detail

With decades of experience in both hydrogen atmosphere processing and the heat treatment of automotive steel, EBNER is a global market leader and has earned a reputation for quality and safety in hydrogen processing.

The hydrogen quench is a revolution in precisely controlled cooling.Incredibly high cooling gradients in excess of 200 K/s.mm (see temperature curve), plus the ability to interrupt quench and then control the temperature at a technologically advantageous level give our customers very high throughputs as well as more options for further transformation of the material microstructure.

Best material

  • >200 K/s.mm cooling gradient in quench.
  • Precise cooling across the entire strip profile, width and length.
  • Excellent flatness and cleaner strip surface.
  • Unique quench patterns meet UHSS/AHSS and next generation AHSS.
  • Up to 100% martensite.
  • Dual phases with varying volume fraction of ferrite and martensite.
  • TRIPs and complex phase, with varying volume fraction of martensite, bainite, retained austenite and ferrite.
  • 580 - 1700 MPa yield strength.

Our most recent reference

An EBNER HICON/H2Q® CAL continuous annealing line successfully started operation in early 2017. HyCAL Corp. will be the first company in North America to offer continuous heat treatment of steel in straight hydrogen atmosphere on a toll processing basis.

One of EBNER’s significant advantages is our in-house full-scale R&D lab, which is staffed by our experienced development team (see photo). Our team constantly researches, develops, tests and refines innovative facilities like this one.
