Aluminium Coil/Foil Annealing Furnaces

Coil Annealing

Sistem Teknik designs and produces furnaces for the homogenisation annealing, intermediate annealing, and final annealing of aluminium coils. These furnaces are generally manufactured for the Natmosphere according to alloy requirements with O2 levels reduced to values as low as 0.1%. Materials are cooled down to temperatures below 300 °C through the usage of the gas and water heat exchanger.

Our foil annealing furnaces provide a temperature homogeneity of less than ± 4 °C. With the implementation of the fan drive control, less energy is consumed during the soaking period. The economiser allows fresh air suction and the provision of the protective N2 gas, which is heated with the furnace exhaust. This circular system increases energy savings significantly. Indirect gas heating (with self-recuperator burners and radiant tubes) or electric heating can be used according to customer demands.  

Our annealing systems implement industry 4.0 solutions with the use of automated multi-directional smart charging cars and user-friendly PLC and SCADA interfaces.

Foil Annealing

Sistem Teknik designs and produces N2 atmosphere furnaces for annealing aluminium foils as well as removing oils remaining on the material from the rolling process. As opposed to many other companies in the industry, Sistem Teknik uses a negative atmosphere system in these furnaces to maximise oil removal. 

Our foil annealing furnaces provide a temperature homogeneity of less than ± 3 °C. With the implementation of the fan drive control, less energy is consumed during the soaking period. The economiser allows fresh air suction and the provision of the protective N2 gas, which is heated with the furnace exhaust. This circular system increases energy savings significantly. Indirect gas heating (with self-recuperator burners and radiant tubes) or electric heating can be used according to customer demands.
