Car Bottom Furnace
The car bottom furnace is a flexible single chamber furnace design that can be customized to meet many processing requirements. Furnaces can be provided in electric, direct fired and indirect gas fired configurations to meet specific processing requirements.
The furnace is typically loaded through a single vertically opening door, but the furnace can be configured as a lift cover or with doors at both ends. Furnaces can be provided up to 75 feet long, 20 feet wide and 20 feet tall with load ratings exceeding 1,000,000 pounds.
The car bottom furnace can be combined with loading cars, companion quench tanks, and washers to form complete heat treating cells.
