The world’s first 100% hydrogen continuous anneal line for automotive steel.
Available on a toll processing basis.
Coming to HyCAL Corp. in late 2016:
Coming in 2016: North America’s first 100% hydrogen continuous annealing line for UHSS/AHSS.
The first of its kind in the world, the new CA line for steel at HyCAL Corp. will use an optimized blend of hydrogen – rather than water – for quenching to produce AHSS grades including: DP (dual phase), TRIP, Martensitic, Q & P and other grades from 580MPa-1700 MPa yield strength.
Water quench = waste. Hydrogen quench = profit.
Due to the superior quenching control of our optimized hydrogen blend, the new CA line will deliver 95% prime yield with superior and incomparable flatness. No water is used in the process so there is no potato chipping and no post anneal shape correction is needed. Your material will be flat right off the CA line.
Stop wasting money with product produced in water quenching lines.
HyCAL Corp. makes it easy.
There is considerable pressure to deliver tomorrow’s high strength automotive steels today. But rather than rush into a huge CA line investment or use product produced in a water quench CA line, you can use the new HyCAL Corp. CA line to help you determine:
• The products you want to provide to the market
• The process that gives you the best results
• The markets you want to venture into
• The true size of the market
And you can do it all on a pure toll processing basis. With no risk and no investment.
100% hydrogen continuous anneal delivers 95% prime steel with incomparable flatness.

Initial coil trials
Ebner pioneered the use of 100% hydrogen in batch annealing and now is changing the game again with hydrogen quenching for continuous annealing. Hydrogen delivers more consistent properties and shape and much higher yields than standard water quenched lines.
Ebner H2 Quench systems are currently being utilized at:
• Numerous Harden and Temper Lines throughout the world [up to 550 mm or 21.7”]
• Mini CAL – in Germany for DP grades [800 mm or 31.5”]
• Dozens of stainless bright anneal lines worldwide [up to 1600 mm or 63”]
Automotive wide strip applications:• Ebner has provided aluminum processing
lines for automotive products to all the major aluminum producers worldwide
• A premier exposed automotive galvanizing/galvannealing line in Europe
Hydrogen quenching eliminates the shape rejections that are typical with water quench processes.
Flatness is guaranteed for most gauge, width and grade combinations.
Lose the water and get considerably more useable material from every coil.
Stop watering down your yields.
Hydrogen innovation continues to change
the world.

MATERIAL: COLD-ROLLED
FULL HARD STEEL STRIP
Processing capacity: 109,000 mt/year (120,000 USt/year)
Effective production time: 6,400 h/year
Width: 610 to 1,219 mm (24” to 48”)
Thickness: 0.50 to 2.29 mm (0.02” to 0.09”)
Throughput capacity: max. 18.2 mt/h (20.1 USt/h)
Hydrogen atmosphere: more uniform heat dissipation
Quench Section provides quenching flexibility
Can reheat the strip up to 1,022° F or not be utilized at all depending on target properties
Hydrogen gas coolingresults in 95% prime yield and dead flat material
Up to 100% martensite
Heating section: max. 980°C (1,796°F)
Unique quench patterns possible to meet complex UHSS/AHSS and next generation AHSS
Examples:• 1,500 M cycle
developed for the furnace does not utilize any heat in the overaging zone
Dial in precise cooling across the entire strip profile, width and length
Dual Phases – with varying volume fraction of ferrite and martensite
Transformation section: max. 550°C (1,022°F)
Slow Cooling Zone after the furnace
• 980 DP cycle developed for the furnace utilizes an overaging zone temperature of 824° F for 60 seconds
Can totally control the cooling process and engineer the strip to exact properties
No water is used for quenching, eliminating shape problems (potato chipping)
Hydrogen quench results in cleaner strip with more precise properties across the entire strip.
TRIP’s and Complex phase – with varying volume fraction of martensite, bainite, retained austenite, & ferrite
155 single end recuperative radiant tubes
Jet Cooler offers varied cooling rates
There is little microstructural change in the overaging zone, only tempering and diffusion
Strip exit temperature: <82°C (180°F)
Quench can be interrupted for tailored microstructure [e.g. stop at bainite nose for QP steel or for partially transforming to martensite & retain austenite]
