HORIZONTAL TEMPERING FURNACE
TYPE VTR-5050/48F
Horizontal retort furnace for vacuum tempering. The pumping system, power supply, and cooling systems are appropriately sized to accommodate a broad spectrum of industrial heat treatment applications, encompassing tempering, degassing, annealing, and solution heat treatment. A hot gas recirculation fan ensures rapid and uniform temperature elevation, streamlining the tempering process within an automatically sequenced cycle. The cooling gas recirculation system incorporates an external blower to enhance both the uniformity and pace of charge cooling during quenching.
