A company in the foundry industry will use two natural gas fired walk-in ovens to dry sand cores used in the casting process of a variety of parts. The equipment, which was manufactured and shipped by Wisconsin Oven, has a maximum temperature rating of 500°F (260°C).
Guaranteed temperature uniformity of ±10°F at 500°F was documented with a nine-point temperature survey. The oven bodies were constructed with tongue-and-groove panel assemblies using the company’s patented panel seams, which provide improved insulating efficiency.
The sand core dryers have the capability to dry water and resin from 6,000 lb of sand cores and a 600 lb steel load car from 70 to 450°F within two hours.
