SECO WARWICK ALLIED, with technologies provided and fully backed up by SECO/ WARWICK offers custom engineered aluminium [aluminium] coil and foil annealing furnaces with capacities ranging from single coil modular furnaces to multi-zone furnaces with tight zone control. These efficient furnaces have exceptional temperature uniformity and unique charging techniques to fit the most demanding application. Two significant improvements for coil and foil processing include mass flow design to protect load surfaces that are vulnerable to damage during high atmosphere flow and vortex flow jet heating system that reduces cycle time by taking advantage of the high heat transfer produced through convection heating.

SECO/WARWICK holds patents for innovations on controlling air flow recirculation over various sized loads, increasing heat transfer and uniformity. Innovations include incorporating both vertical air flow with specially designed vertical baffles on each side of the load and the high velocity directed mass flow system.

To obtain the shortest possible cycle without any loss of quality in the material, SECO WARWICK ALLIED offers The Vortex Flow Jet Heating System incorporating arrays of 4 round inclined nozzle jets that generate a spiral vortex motion of air that results in high heat transfer without producing hot spots in the coil.

Aluminium Homogenising Furnaces

SECO WARWICK ALLIED manufactures custom engineered aluminium log, billet and slab homogenising [homogenising] furnaces for most process applications. Equipment designs include batch types [both car and tray designs], traveling styles and continuous styles. Unique reversing air flow designs and temperature control systems produce fast heating rates and close temperature uniformity throughout the entire load.

With batch type design, typically an electrically-driven, insulated car is used to move a load into and out of the furnace.

Another type of batch unit offered by SECO WARWICK ALLIED is the traveling furnace. This furnace utilizes a pair of fixed load bases to support the load. A traveling furnace provides savings in floor space since the two load bases require significantly less floor space than a double ended stationery furnace with two load cars.

SECO WARWICK ALLIED’s Continuous log homogenizers are used by plants having higher production levels and a narrow range of product to be homogenized. High velocity jet heating is used to heat each log to homogenizing temperature very quickly.

The furnaces incorporate vertical airflow with specially designed vertical baffles on each side of the load as well as high velocity directed mass flow system. Radiant tubes for either gas fired burners or electric heating elements protect the load from direct impingement of Flame / radiation and maximise temperature uniformity.

Vortex Jet Heating System

To avoid quality problems particularly at the strip edges due to direct impingement of non-uniform hot airflow on the coil. VORTEX FLOW JET heating system is adopted. This incorporates arrays of 4 round inclined nozzle jets, which generate a spiral vortex motion of air that results in high heat transfer without producing hot spots in coils.
