L&L Special Furnace Co. shipped a floor-standing box furnace to an aerospace company in eastern Canada. The furnace will be used for curing and bonding ceramic coatings to various steel bodies primarily deployed in the aerospace industry. This process provides extra strength to aerospace parts that are subject to various temperatures and stresses under normal operating conditions. The furnace has an effective work zone of 22 inches wide x 16 inches high x 20 inches deep. A horizontal door with ceramic hearth and support bricks is included to incorporate the customer’s loading system. Nickel-chrome elements that are resistant to any potential contamination the process may cause are used. Heat shields provide a safe-to-touch case temperature under operating conditions.
The Industrial Heating Equipment Association (IHEA), the Chemical Coaters Association International (CCAI), Products Finishing magazine and Southern Company have teamed up to provide a comprehensive training course. The Powder Coating and Curing Processes Seminar is scheduled for October 20-21 at the Alabama Power Technology Application Center (TAC) in Calera, Ala.
L&L Special Furnace Co. Inc. shipped five box furnaces to a manufacturer of chemicals and chemical coating products located in the Midwest. These products are primarily used in the medical field as a coating and must be cured at 800°F. The furnaces can also be used for sintering of chemical powders up to 2200°F. The furnaces have an effective work zone of 10 inches high x 15 inches wide x 13 inches deep. They are designed to be placed on a benchtop or with an optional furnace stand.
Wisconsin Oven Corp. shipped an electrically heated, Ferris-wheel batch oven to the aerospace industry. It will be used to cure epoxy resins and varnishes on assorted aerospace parts. The oven, which has a maximum operating temperature of 500°F, has work-chamber dimensions of 3 feet, 4 inches wide x 3 feet, 6 inches long x 3 feet, 6 inches high. When the configuration of the workload is such that it is capable of absorbing the heat, the heavy-duty unit has sufficient capability to heat 200 pounds of product to the company’s specified temperature range within two hours.
Epcon Industrial Systems designed, built and shipped a state-of-the-art multi-zone conveyor oven system that will be used to cure internal linings for 55-gallon drums. The effective heating zone oven measures 100 feet long x 6 feet wide x 6 feet, 6 inches high. The custom-designed oven has three independently controlled heating zones operating at a temperature range of 350-600°F and three dual-lane conveyor systems to process the drum and the top/bottom lids simultaneously.
A natural gas continuous conveyor oven was created to cure disc pads. Its tray-based conveyance moves products through the system standing up in a vertical arrangement made possible by the heat-resistant trays, which accommodate eight parts apiece.
