Product catalog summary
Introduction
SECO/WARWICK is a global leader in heat treatment and metallurgy solutions, operating in nearly 70 countries. The company provides innovative and environmentally friendly products across five main categories: vacuum heat treatment, atmosphere processing, aluminum thermal processing, controlled atmosphere brazing, and vacuum metallurgy.
Aluminum Annealing Furnaces
SECO/WARWICK specializes in custom-engineered aluminum coil and foil annealing furnaces. These furnaces feature Mass Flow design for foil annealing and Vortex Flow jet heating for coil annealing, ensuring high heat transfer and uniform temperature distribution.
Furnace Efficiency
Efficiency is enhanced through a thermal head, air-to-work ratio control system, and a proprietary mesh and mortar insulation system, increasing insulation efficiency by 15-20% and simplifying maintenance. Radiant tubes are designed for longevity, contributing to overall efficiency.
Temperature Uniformity
Temperature uniformity is achieved through patented airflow recirculation designs and vertical baffles, improving air stream uniformity and protecting the load from direct heat radiation. The design includes two temperature-control zones for each recirculation fan.
Bypass Coolers
Proprietary bypass coolers maintain atmosphere temperature below 1750°C to prevent oil baking on heat exchanger fins. These coolers are available in various sizes and can be mounted according to space availability.
Conclusion
SECO/WARWICK's advanced convective heating systems, such as the Vortex Flow jet heating system, ensure uniform heat distribution, particularly effective for aluminum coils, optimizing the heating process through the edges of coil wraps.
Specifications
Custom-engineered aluminum coil and foil annealing furnaces range from single coil modular to multizone furnaces, designed for exceptional temperature uniformity and efficient heating.
Procedures and Systems
The Mass Flow design for foil annealing and Vortex Flow jet heating system for coil annealing protect the load and ensure high heat transfer efficiency.
Furnace Design Considerations
Advanced convective heating systems prevent quality degradation due to local overheating. The Vortex Flow jet heating system provides uniform heating without hot spots.
Advantages
The High Convection Vortex Flow Jet Heating system achieves uniform surface temperature, reduces heat-up time, improves material property uniformity, avoids local cracking of milling oil, and requires lower electrical fan power.
Company Profile
SECO/WARWICK is a leading supplier of heat treatment and metallurgy solutions, serving industries such as automotive, aerospace, and energy.

Aluminum Annealing Furnaces VARIOUS LOADS NEED VARIOUS SOLUTIONS. THEREFORE FURNACE EFFICIENCY Further efficiencies are realized with SECO/WARWICK’s thermal head, air-to-work ratio control system, which uses separate load and air thermocouples in each control zone. Because the load temperature is constantly monitored, a thermal head is maintained without risk of overheating the SECO/WARWICK IMPLEMENTED load. When the load approaches metal set point, the air Mass Flow design, especially for foil annealing where the surface of the load is vurnerable for damages during high atmosphere flow. Vortex...

load configuration. In very large coil applications and where tight temperature tolerance is required, SECO/WARWICK designates two temperature-control zones for each recirculation fan. This field-proven design compensates for differing coil characteristics, combustion performance, and loading practices. BYPASS COOLERS SECO/WARWICK provides a proprietary bypass cooler Our insulation system starts with several millimeters of board-type insulation covered by a ceramic fiber blanket. A stainless steel wire mesh covers the entire insulating surface and is coated with a high- temperature mortar, which...

of the coil or even fatal degradations by local melting of the convective heat transfer system used. The governing the coil surface. The reason for these degradations is local parameter describing the temperature uniformity of a overheating at the coil head surface caused by non uniform convective heating system is the ratio of maximum to heat flow of the convective heat transfer system used. minimum heat transfer coefficient max/min. This parameter limits also the heat up time since the smaller the max/min The governing parameter describing the temperature ratio the higher is the average ()...

The analysis of the pictures from the thermovision camera, equally scaled, indicated that a more uniform surface temperature was achieved by using the new The heat up time without local overheating can be reduced. Uniformity of material properties is improved. Local cracking of milling oil is avoided.
