Aluminum Aging and Annealing Furnaces
Comprehensive aluminum aging and annealing solutions for the aluminum industry
Various loads need various solutions. Therefore SECO/WARWICK implemented::
/ Mass Flow design, especially for foil annealing where the surface of the load is vurnerable for damages during high atmosphere flow.
/ Vortex Flow jet heating system, for coil annealing when the advantage of high heat transfer can be used.
SECO/WARWICK provides custom engineered aliminium coil and foil annealing furnaces with capacities ranging from single coil modular furnaces to multizone furnaces having tight zone control. We have the experience, knowledge and talent to manufacture efficient furnaces. With exceptional temperature uniformity and unique charging techniques to fit the most demanding application.
/ Mass Flow design, especially for wire, profile, and foil (less than 100microns) annealing, where the surface of the load is vulnerable to damages during high atmosphere flow
/ Furnaces for T77 process heat treatment
/ Continuous roller hearth furnaces for mass production
/ Scrap dryers
/ Stress relieving furnaces.
SECO/WARWICK is manufacturer of chamber aging furnaces meeting most up to date strict AMS and CQI-9 requirements, both for pyrometry and material. Along with the furnace we deliver control system compliant with AMS and NADCAP certification adaptation. All the provided furnaces are tailor-made and sized to Customers’ load baskets and treated parts. Dedicated loading cars facilitate loading process and can be used for continuous process with two door furnace construction.
T77 aging furnaces allow for multi-stage and multi-ramp processes guarantying process repeatability and reliability. Furnace design allows for +/-10% air flow uniformity in the entire furnace. Cold air injection system is provided for low temperature heating.
All the offered furnaces are lined with long lasting and effective mineral insulation.
SECO/WARWICK can provide low cost crap drying furnaces in Class 2 or 3 with the hearth adapted for container loading with the use of forklift. Furnaces provide simple recirculation systems with the use of centrifugal fans and water vapor evacuations system.
Heating system is based on compact, low cost, easy-to-replace heating elements. Control cabinet is installed on the furnace and equipped with simple controller for process parameters input.
The doors are opened manually.

The analysis of the pictures from the thermovision camera, equally scaled, indicated that a more uniform surface temperature was achieved by using the new High Convection Vortex Flow Jet Heating system.
The coil surface temperature uniformity profiles present the overview of temperature uniformity for the entire heat up cycles. This confirms that better surface uniformity was achieved by the vortex nozzle system. The a min/a max ratio calculated based on the above data is 1,25 for vortex nozzle system. For aluminum alloys of lower thermal conductivity, the results in this parameter is expected to be even higher.
/ The heat up time without local overheating can be reduced
/ Uniformity of material properties is improved
/ Local cracking of milling oil is avoided
/ Lower electrical fan power because of lower speed in spite of higher volume flow
/ Aerospace
/ Automotive
/ Energy
/ High efficiency auto recuperator burners up to approx. 86% output, heat recovery from the exhaust for nitrogen heating
/ Ecological, biosoluble insulation with a properly selected thickness to optimize losses through the walls
