A forging company will use a natural-gas-fired belt conveyor oven to preheat aluminum billets. Manufactured by Wisconsin Oven Corp., the unit has sufficient capability to heat 3,000 lb per hour of aluminum from 70 to 950°F as long as the workload is configured in a manner that is capable of absorbing the heat that is generated within the time available. The oven has a maximum temperature of 1000°F with guaranteed temperature uniformity of ±10°F at 950°F.
The continuous oven was designed with both top-down and bottom-up airflow to maximize heating rates and temperature uniformity of the part load configuration. The conveyor system utilizes a stainless steel flat wire belt, and a variable-frequency drive provides adjustable speed control.
