Abstract
Hot-chamber diecasting machines for processing magnesium melts include a casting vessel, an inductive heating system, and an additional ring inductor in an area of the neck of the casting vessel in order to achieve a heating also in this area. The ring inductor is formed of a one-piece tube made of an elastic material which is open at one point and can be bent open by the extent of the diameter of the neck of the casting vessel and can be pushed laterally onto the casting vessel, and through which air can also flow for the cooling.
