For processes such as solution annealing, artificial ageing, or soft annealing requiring high temperature uniformity and optimum charging ability for heavy charge weights, we recommend bogie hearth furnaces with air circulation.

• Maximum temperatures of 650 °C or 850 °C
• Bogie on rails
• Swing door hinged on the right
• Electrically heating of two sides and bogie
• Optimum temperature uniformity (according to DIN 17052-1) up to ΔT 14 K
• Powerful fan with vertical air circulation
• Air baffles at furnace sides for optimal air circulation
• Over-temperature limit controller with adjustable cutout temperature for thermal protection class in accordance with EN 60519-2 as temperature limiter to protect the oven and load

Additional Equipment

• Powerful direct gas heating
• Fixed hearth and movable furnace (envelope concept) for heavy charges up to 100 tons
• Electro-hydraulic vertical lift-door
• Horizontal air circulation for optimal temperature throughout the useful height
• Electrical bogie drive
• Second door in combination with second bogie for alternating operation and optimal charging
• Fully automatic bogie change
• Fan system for faster cooling
• Automatic control of exhaust air vents for optimal cooling of the furnace chamber
• Optimal temperature uniformity (according to DIN 17052-1) up to ΔT 6 K on models with multiple zones of control
• Support structure made from heat-resisting cast alloy steel for high charge weights
• Heat-resistant boxes for protective gas or carburization processes
• Process and charge documentation via Controltherm software or PLC-based control system
• Custom dimensions up to 30,000 liters
