Aluminium Foil Annealing Furnace (FAL)
Foils made of Aluminium require individual heat treatment within a narrow temperature window for achieving optimum material properties, low deformation and minimal residual stress.
Overview
MULTI-CHAMBER FURNACE PLANT FAL
The foil annealing furnace FAL of Tenova LOI Thermprocess consists of max. 5 separated chambers which can be operated individually.
The charges of the foil coils arriving from the rolling mill are collected on suitable storage places. A set of foil coils is then compiled to a charge and positioned on an annealing rack. The charging is executed by a charging machine which transversely travels to the individual furnace chambers. All functional processes are executed fully automatically. Every individual heat treatment is assigned to the respective, individual charge, rack or single part, registered and documented.
