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 (H2Q) in place 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 the capability of processing a larger range of strip dimensions. The horizontal version achieves a throughput of 18 t/h, with even higher throughputs possible with our vertical design.
The HICON/H2Q continuous annealing line (CAL) from EBNER, 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.
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, plus the ability to interrupt quenching and then control the temperature at a technologically advantageous level, ensure that our customers achieve the highest throughputs. Furthermore, they have a variety of options to further transform the material microstructure.
