Wisconsin Oven shipped a natural-gas-fired walk-in oven to a manufacturer in the die-casting industry. The industrial oven, which will be used for aluminum age hardening, has a maximum temperature of 509°F and chamber dimensions of 5 feet wide x 10 feet long x 8 feet high. The company required guaranteed temperature uniformity of ±10°F at 509°F, which was documented through a standard nine-point profile test.
A combination airflow arrangement provides both horizontal and vertical upward airflow, which maximizes heating rates and temperature uniformity of the product. The oven also includes a motorized, modulating gas control valve; flame detector and relay with alarm horn; digital process timer; and digital temperature controller and high limit controller.
