Wisconsin Oven Ships Tempering Batch Oven to a Heavy Equipment Manufacturer

Oct 27, 2017

Wisconsin Oven Corporation shipped an electrically heated enhanced duty batch oven with powered load car to a heavy equipment manufacturer. The batch oven will be used for pre-heating and tempering a variety of steel components. It is designed with the capability to heat 15,000 pounds of steel at a time per the customer’s requirements.

This tempering oven has a maximum temperature rating of 500° F and work chamber dimensions of 8’0” W x 8’6” L x 5’0” H. The customer required guaranteed temperature uniformity of ±10°F at set points of 300° F and 500° F.  A fourteen (14) point profile test conducted in an empty oven chamber under static operating conditions was performed to confirm the uniformity.

The tempering oven is constructed with tongue and groove panel assemblies that feature Wisconsin Oven’s patented high efficiency panel seems and provide 25% better insulating efficiency. The recirculation system utilizes combination airflow to maximize heating rates and temperature uniformity of the product. A powered load car rated at 15,000 pounds utilizes a variable frequency AC drive with electronic torque limiting to move the load in and out of the oven.

When designing an oven for a heavy load weight such as this project, the airflow arrangement and heating input are key factors in achieving the desired heat up rates.” Jeff Judd, Sales Engineer.

Unique features of this batch oven include:

  • Guaranteed temperature uniformity of ±10°F at set points of 300° F and 500° F
  • Two (2) 8,600 CFM @ 10 HP recirculation blowers
  • 228 kW heating system with SCR power control
  • Eurotherm programmable temperature control and high limit control
  • Ethernet communication capability
  • Powdered load car rate for a 15,000 pound load
  • Vertical lift, pneumatically operated door
