Chain Conveyor Oven Shipped to an Automotive Parts Manufacturer

Wisconsin Oven Corporation has shipped a natural gas fired indexing conveyor oven to an automotive parts manufacturer in Canada. The chain conveyor oven will be used to preheat aluminum billets prior to forging into automotive suspension components under high pressure. This forging process produces high-strength parts that are suitable for applications where performance and safety are critical, but a lighter-weight metal is needed for speed or energy efficiency.

The maximum operating temperature of this indexing conveyor oven is 1,100 °F and the work chamber dimensions are 6'6" W x 23'6" L X 1' H. The oven is designed with the capability to heat 1,995 lbs. of aluminum per hour and a production rate of 360 parts per hour. The equipment achieved temperature uniformity of +/-10 °F at 1,050 °F (565 °C) for the last 90 index positions.

The conveyor oven body is constructed with Wisconsin Oven Corporation's patented, efficient Expandable Surface design. This includes 2" of high temperature block insulation backed with 4" of semi-rigid batt type insulation. The oven has adjustable insulated profile doors at both ends above the conveyor and four personal access plugs.

"This indexing oven utilizes a four-chain conveyor. Each chain has attachments that hold the billets, which are cylindrical shaped. They are carried through the oven in two rows, with two chains conveying each row of billets. The billets need to be forged while at a temperature of approximately 900 °F, so a robot reaches into the oven exit end removes the billet from the conveyor before it has a chance to leave the oven and cool down," said Mike Grande, Sales.

Features of the oven include:

  • Temperature uniformity of +/-10 °F at 1,050 °F for the last 90 index positions
  • Five emergency stop buttons for maximum safety
  • Top-down airflow to maximize heating
  • Allen Bradley PowerFlex 525 variable frequency AC conveyor drive
  • Industrial air heat burner rated at 3,500,000 BTU per hour
  • Four total calibrated thermocouples
  • Eurotherm 3504 programmable temperature controller.

The chain conveyor oven was fully factory tested and adjusted prior to shipment from the facility. All safety interlocks are checked for proper operation and the equipment is operated at the normal and maximum operating temperatures.
