Wisconsin Oven shipped a natural-gas-fired draw batch oven to Flame Treating Systems Inc. in Durham, N.C. The oven, which will be used for tempering various steel parts, has a maximum temperature of 1250°F and basket dimensions of 4 feet wide x 3 feet high x 4 feet long. Steel parts are loaded into the oven in the basket on two stainless steel pier rails with a load capacity of 2,000 pounds gross. The recirculation system features a combination airflow arrangement that provides both horizontal and vertical upward airflow, which maximizes heating rates and temperature uniformity of the product.
The tempering oven, which was fully factory tested and adjusted prior to shipment, 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.
