The loaded trays are placed in a baseframe by the customer's loading system. This baseframe is positioned on the charging car. Once the car has been loaded by the customer's equipment, all subsequent steps are automatically executed by the control system in line with the specific recipe. The loaded car moves under the furnace and the furnace's winching mechanism lowers the receiving fixture, then engages the baseframe at the predetermined points to pull the charge into the furnace.
For the entire treatment time, the charge remains suspended in the furnace. At the end of the programmed cycle duration the furnace bottom is opened rapidly and the charge is lowered into the water bath for quenching. After the programmed quench time, the charge is pulled out of the water again and allowed to drip-dry for a defined period of time. The charging car then moves under the charge, takes it over and delivers it to the customer's unloading system.
