Pouring furnaces

In 2017, we added this furnace design to our portfolio after developing it specifically for a customer.
The target was to avoid the heat losses associated with conventional casting channel furnaces during downtime. With this type of channel furnace, the channel and a minimum metal cover must be kept liquid during downtime. Our customer planned a single-shift operation, approximately 2-3 days per week.

Therefore, we combined a crucible furnace with a pouring system in the center of the furnace, featuring a slight slope towards the center of the bottom. This allows the furnace to be completely emptied at the end of each shift and, due to the medium operating frequency, restarted with cold material with its own power at the beginning of each shift.
Additionally, a filling point for liquid metal was designed into the furnace head. The furnace is movable on rails, and the media are supplied via a cable conveyor. The compensation capacitors were mounted on the rear of the furnace housing in a temperature-protected location, ensuring that only the compensated current had to be carried through the cable carrier.

The plug is controlled via a joystick and proportional valve. Casting curves can be read into the programmable logic controller (PLC) and, if necessary, manually adjusted on the control panel. This allows the casting process to be transferred to the PLC as soon as a casting curve for the casting is stored..
