HICON/H2® bright-annealing lines for low-alloyed and high-alloyed steel strip and special grades

Highest quality, greatest efficiency and best performance for alloyed steel strip.

These factors define our bright annealing lines and are the basis for global success. Today, more than 50 bright annealing lines produce material to the strictest quality standards in 16 countries.

The EBNER bright annealing concept in vertical or horizontal form is designed with the proven muffle concept to make use of the pure hydrogen atmosphere with lowest dewpoint (-60 °C) for these oxidation-prone alloys. The result is a clean, damage-free surface as well as perfect mechanical values in the annealed strips.

EBNER technology can process strip with a very high width to thickness ratio. The strip dimensions to be processed at these facilities are between 0.025 and 5.0 mm thick and up to 1600 mm wide with temperatures ranging up to 1180 °C.

The facility can be implemented to comply with the standards required by the automotive industry in accordance with CQI-9 (AIAG).
