The OTTO JUNKER pouring furnace, type RGD/UGD, is made up of the cylindrical furnace vessel with siphon-like filling gate and pouring spout and stopper mechanism.
The unit may be of either heated or unheated design.
Unheated types can be converted to heating at any time later by retrofitting a channel-type inductor.
The filling gate and pouring spout may be arranged at a 90° or 180° angle relative to each other. The vessel can be tilted hydraulically about the filling gate for emptying. It is thus possible to pour different alloys from a single vessel. For filling mould sprue cups at different positions, the furnace base frame is mounted on a double carriage which enables the unit to travel along and across the mould line.
Pouring into the mould takes place with constant metal level by pressurization control using the pouring stopper-nozzle principle.
