A Canadian automotive parts manufacturer recently contracted a chain conveyor oven to preheat aluminum billets prior to forging into automotive suspension components under high pressure. This forging process produces high-strength parts that are ideal for applications where performance and safety are critical, but a lighter-weight metal is needed for speed or energy efficiency.
The natural gas-fired indexing conveyor oven, constructed and shipped by Wisconsin Oven Corporation, has a maximum operating temperature of 1,100°F (593° C) and work chamber dimensions of 6’6” W x 23’6” L x 1’0” H. The oven is designed with the capability to heat 1,995 pounds of aluminum per hour and a production rate of 360 parts per hour. The equipment achieved temperature uniformity of +/-10°F (5.6° C) at 1,050° F (565° C) for the last 90 index positions. The patented Expandable Surface™ design includes 2 inches of high-temperature block insulation backed with 4 inches of semi-rigid batt type insulation.
