ffeim The analysis of the pictures from the thermovision camera, equally scaled, indicated that a more uniform surface temperature was achieved by using the new H igh Convection Vortex Flow Jet Heati ng system. The coil surface temperature uniformity profiles present the overview of temperature u niformity for the entire heat up cycles. This confirms that better surface uniformity was achieved by the vortex nozzle system. The a min/o 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 isavoided ■ Lower electrical fan power because of lower speed inspite of higher volume flow SECO/WARWICK GROUP N is a leading global manufacturer of heat treatment furnaces and equipment SECO/WARWICK is a technological leader in innovative heat treatment furnaces.

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 load. When the load approaches metal set point, the air temperature is reduced in direct proportion to the rate of rise in load temperature. Therefore, the maximum amount of thermal head is maintained for the maximum amount of time, resulting in the shortest possible heating time. To further...
