Wisconsin Oven Corp., East Troy, Wis., has shipped two natural-gas-fired enhanced-duty walk-in batch ovens that are designed to dry the sand cores used in the casting of a variety of parts. The sand-core dryers have the capability to raise the temperature from 70 to 450°F, driving water and resin from 6000 pounds of sand cores and a 600-pound steel load car within two hours.
Work chamber dimensions are 10x8x20 inches, with a maximum temperature rating of 500°F. Guaranteed temperature uniformity of ±10°F at 500°F was documented with a nine-point temperature survey. The oven bodies are constructed of tongue-and-groove panel assemblies featuring Wisconsin Oven’s patented high-efficiency panel seams that provide 25% better insulating efficiency.
“These sand core dryers were designed to maximize efficiency and decrease drying time of the cores,” says David Burke, Sales Representative, Torrid Enterprises. “The customer is able to pour and dry more cores in less time than before, resulting in increased production.”
The dryers were fully factory tested and adjusted prior to shipment. All safety interlocks were checked for proper operation and the equipment was 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.
