Continuous annealing facilities for uncoated and coated steel strip

FLEXIBILITY AND INNOVATIVE SOLUTIONS FOR GALVANIZING, GALVANNEALING AND TINPLATING USING CONTINUOUS STRIP ANNEALING LINES.

The furnaces are used for galvanizing lines (CGLs) and continuous annealing lines (CALs) and can be radiant tube heated or gas-fired with a muffle.

Well-established technology has been refined by EBNER for the annealing furnaces as well as for the coolers - e.g. HICON® jet cooler (patented).

All furnace types feature components manufactured or approved by EBNER. These components include burners, radiant tubes, control valves for the combustion system, heat-resistant material for muffles, hot bridles, insulating materials etc.

Applications:

Vertical:

  • Furnaces for continuous galvanizing lines (CGL) for car body sheet up to 2100 mm wide
  • Continuous annealing lines (CAL) for car body sheet up to 2100 mm wide
  • Mini CAL for deep drawing grades, poly-phase grades and metallically coated strips up to 700 mm wide

Horizontal:

  • Decarburization lines for grain-orientated electrical strip (silicon steel) up to 1050 mm wide with a thickness of e.g. 0.65 mm
  • Annealing lines for non-grain-orientated electrical strip up to 1200°C
  • Furnaces for continuous galvanizing lines (CGL)

Mini CAL (horizontal) to anneal deep-drawing grades, poly-phase steels and special grades

One annealing line - three technologies

  • recrystallization
  • dual-phase cycles
  • normalization

Thanks to hydrogen cooling technology, cooling gradients of 100 to 150 K/s are achieved while heat treating poly-phase steels and IF grades.

Strip up to a max. width of 800 mm for a variety of applications in the white goods, electrical and automotive industries can be annealed in the horizontal facilities at a throughput of up to 1.3 t/h.
