Single-Coil-Annealing-Line SCL for Aluminium Strip

The Single-Coil annealing provides a flexible solution for the heat treatment of coiled Aluminium strip. Single coils fully automatically can undergo their specific processing. This solution is preferred if the production requires reaction to frequently changing requests for individual strips or if specific processing is applicable to only a small lot of strips.

For bigger lots the same furnace technology is applicable as Multi-Coil Annealing Line MCL including charging machine.

The plant consists of several furnaces in line, which operate independently with a common charging system. The Single-Coil Lifting Hearth Furnaces SCL are loaded by the charging machine, which moves under the furnaces. From a central charging and discharging station the coils are transferred to the individual chambers. Each furnace unit is loaded with one coil.

The furnace system is working with electric or natural gas heating. With fuel heating the burners are installed in δ-tubes, which allow indirect heating. The burners are equipped with heat exchangers for heating up the incoming combustion air by the outgoing flue gas.

The furnaces are gas tight for processing the strips in inert gas atmosphere. Furnaces can be equipped with atmosphere transfer to a thermal oxidizer for burning rolling oil, which evaporates during heating up.

With Single-Coil annealing there is no need for complex batch assembly, considering coils of the same size, alloy composition and annealing program.

For bigger batches the Multi-Coil Annealing Line MCL is the right choice. Here the furnaces are loaded with a batch, consisting of a batch of the same coils.

Specific benefits of SCL:

  • Individual short heating-up and cooling time
  • No overheating of coil edges
  • Homogeneous annealing temperature
  • Less space requirement
  • Individual annealing of each Coil
  • In time annealing
  • Integrated fully automatic charging
  • Automatic connection to warehouse system
  • Individual recording of the processing
  • Extendable line arrangement
  • High availability
  • Indirect gas firing or electric heating system
