The Vertical Box-Type Quenching Furnace is an advanced thermal processing system engineered for precision, efficiency, and reliability. Its robust structure includes a dual-section frame—supporting the heating chamber, lifting mechanism, and integrated spray cooling system—along with a dedicated control unit housing intelligent electrical and power distribution components. The furnace employs high-purity silicon carbide heating elements and an energy-efficient alumina polycrystalline fiber chamber, ensuring superior thermal uniformity and low energy consumption. With a fully automated lifting mechanism and dual air/water quenching capability, the system enables rapid heating and controlled cooling processes. Operation is simplified through a centralized 7-inch touchscreen interface, which offers real-time monitoring and adjustment of temperature, flow rates, and movement, all supported by S-type thermocouples and PID control for exceptional accuracy.
Ideal for a wide range of industrial heat treatment processes, this box-type quenching furnace is widely used in metallurgy, automotive, aerospace, and tool manufacturing sectors. It performs critical operations such as hardening, tempering, and quenching of metal components including gears, shafts, molds, and structural parts. The flexible spray cooling system allows users to switch between air and water quenching, accommodating different material requirements from alloy steels to non-ferrous metals. With built-in safety protections like over-temperature and heating element burnout alarms, this system ensures both process repeatability and operational safety, making it suitable for both laboratory research and high-volume production environments.
