Wisconsin Oven Ships Two-Zone Belt Conveyor Oven for Steel Tempering
Wisconsin Oven Corporation is pleased to announce the shipment of a two (2) zone belt conveyor oven that will be used for tempering various steel parts after induction hardening. This oven is designed for precise temperature control and energy efficiency.
The conveyor oven is capable of heating 2,400 pounds of steel per hour from 70°F to 350°F, with a maximum temperature rating of 500°F. The recirculation system features a top-down airflow design with a 32,000 CFM blower, with each of the two zones utilizing 16,000 CFM. The temperature for both zones is controlled by a Watlow F4T digital recorder/controller, which provides Ethernet communication capabilities and PID temperature control with adaptive tuning. To ensure compliance with AIAG specification CQI-9, a temperature uniformity survey was conducted, documenting uniformity of ±10°F at 350°F with verified part soak.
The oven is equipped with a continuous belt style conveyor that utilizes a variable frequency drive for speed adjustments. The work zone dimensions are 4’0” W x 21’0” L x 14” H. To maximize energy efficiency, the oven is designed with an E-Pack™ Energy Efficiency Package. This upgrade includes 2” thicker insulation in the walls, floor, and roof, as well as variable frequency drives on the recirculation blowers. These design features reduce energy consumption and operating costs. Depending on utility rates, operating temperature, and weekly usage, customers may achieve significant annual energy savings with an E-Pack™ Energy Efficiency Package.
"The customer chose to enhance the operating efficiency of the oven with the E-Pack™ Energy Efficiency Package. Depending on utility rates, operating temperature, and weekly usage, customers may achieve significant annual energy savings with this upgrade." - Tom Trueman, Senior Application Engineer
