Spray Quench Aluminum Solution Furnace

Wisconsin Oven is pleased to announce the completion of a Horizontal Spray Quench Furnace for C/A Design located in Dover, NH. This furnace will be used for the solution treatment of aluminum. The system is designed to soak the product load at temperature in the furnace and then a pusher mechanism rapidly moves the load into the spray quench. The spray quench offers reduced distortion in comparison to submersion quenching.

The maximum temperature for this system is 1,150°F and it has sufficient capacity to heat a 200 pound aluminum load plus the work grid and product fixture. A temperature uniformity survey was documented for +/-10°F at 985°F to verify the furnace has the capability to meet AMS 2750G, Class 2 furnace and Instrumentation Type D requirements.

The spray quench is located in front of the oven and has vertical-lift, pneumatically operated doors on each end. The spray quench system utilizes fifty (50) fine mist nozzles located above, below, and on each side of the quench chamber to rapidly cool the product from all sides. Each nozzle is independently selectable from the touchscreen HMI and a variable frequency drive allows the pump speed to be adjusted to maintain a constant pressure to each spray nozzle.
