Abstract:
Hot-chamber diecasting machinefor processing magnesium melts, comprising: a casting vessel with an ascending bore, a conical mouthpiece which in use opens to the ascending bore, a nozzle attached to the mouthpiece, an inductively operating heating device which is operated at a medium frequency or at a frequency at a lower limit of a high frequency, and a ring inductor placed in a plane of a covering of a crucible for the melt around the casting vessel, wherein the ring inductor comprises at least one bendable tube made of an elastic material, which forms a one- piece ring which is open at a point and is provided there with connections for energy and for cooling air flowing through, and wherein the elasticity of the tube ring is so large that, at the open point, the tube ring can be bent open at least by an extent of the diameter of the casting vessel in an area of the crucible covering and can be laterally pushed onto the neck of the casting vessel.
