AI Technical Summary
Traditional tempering furnaces suffer from heat leakage and hot gas accumulation, which affect product cooling efficiency and quality. Furthermore, they operate in harsh environments and lack safety and stability.
It employs components such as air curtain machines, axial flow fans, and chain thermal insulation curtains to form an active air blowing cooling and negative pressure exhaust system. Combined with precise control by temperature sensors, it improves heat dissipation efficiency and prevents hot air from escaping.
It accelerates product cooling, improves production efficiency, enhances the working environment, ensures product quality and the stability of heat treatment processes, and has energy-saving and consumption-reducing effects.
