Wisconsin Oven Corp., East Troy, Wis., has shipped a natural gas-fired four-zone solution treatment conveyor furnace for treating forged aluminum parts for AR-15 rifles prior to quenching in water. The maximum operating temperature is 1100°F, and the work chamber dimensions are 4 1/6 ft. wide x 60 ft. long X 1 ft. high.
Each of the four work zones has dimensions of 4 1/6 ft. wide X 15 ft. long X 1 ft. high. The design capacity of the furnace is 1500 pounds per hour of aluminum. The equipment achieves temperature uniformity of +/-10°F at 750°F and 1100°F.
The conveyor furnace shell features “CAN” type, double-wall construction and includes two inches of 14# density high temperature industrial mineral wool insulation, backed with six inches of 6# density, industrial board type insulation, for a total of eight inches. The shell, including the roof, consists of Wisconsin Oven’s patented high-efficiency Expandable Surface Design. The solution treatment furnace utilizes a flat wire belt to transfer parts through the work zones.
“Temperature control and uniformity was a critical feature in the design of this system,” says Mike Grande, Sales Manager. The equipment achieves the tightest temperature tolerances available in the industry for a furnace of its type.”-
The conveyor furnace was fully factory tested and adjusted prior to shipment from our facility. 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.
