Wisconsin Oven Ships Annealing Furnace



Wisconsin Oven Corporation has shipped an electrically heated annealing furnace to a firearms manufacturer, which will be used for annealing an assortment of brass and bronze firearm caps.

The annealing furnace has a maximum temperature rating of 760 °C (1,400 °F) and a normal operating temperature of 300 °C to 650 °C (572 °F to 1,202 °F). The work chamber dimensions are 3'0" wide x 9'0" long x 6" high. The conveyor furnace, when preheated, has the sufficient capacity to heat 225 kg of product per hour from 23 °C to 650 °C.

The recirculation system was designed with bottom-up airflow. The continuous conveyor system utilizes a pintle chain driven wire mesh belt and variable frequency drive for adjustable conveyor speeds. High temperature profile curtains with external vestibules on both ends of the conveyor reduce heat spill out and improve temperature uniformity. A guaranteed temperature uniformity of ±10 °C at 300° and 650 °C (±18 °F at 572° and 1,202 °F) for a minimum of 33 minutes was documented.

"This conveyor furnace was designed with features to maximize temperature uniformity throughout the work chamber to ensure optimal part results for the customer," said Tom Trueman, Senior Application Engineer.

Features of the annealing furnace include:

  • Guaranteed temperature uniformity of ±10 °C at 300° and 650 °C
  • Wisconsin Oven's patented high efficiency Expandable Surface design
  • High temperature profile curtains both ends of the conveyor
  • Variable frequency drive for conveyor system
  • Programmable temperature controller with fast acting auto-tune
  • High limit controller
  • Proof of conveyor movement sensor.

"This annealing conveyor furnace was fully factory tested and adjusted prior to shipment from our facility," said a company spokesperson. "All safety interlocks are checked for proper operation and the equipment is operated at the normal and maximum operating temperatures. An extensive quality assurance check list was completed to ensure the equipment met all Wisconsin Oven quality standards."
