method for inductive heating of at least one einlegeteils for a verbundgußteil and the application of this procedure, appropriate device

摘要

A process is disclosed for inductively heating an insert (12) in a composite casting, preferably an iron and/or steel materials-based casting. The insert (12) is placed in a casting mould (10) outwardly provided with two opposite recesses (13) that lie on the same plane, and at a distance from the mould cavity (11) and are oriented towards the insert (12). The end pieces (5) of an inductor core (1; 15), upon which is arranged at least one coil (8), are inserted into these recesses (13) and removed after heating. A device for carrying out the process has a C-shaped inductor core (1; 15) (iron core) with a traverse (2; 16) upon which are held core angles (3) provided at their ends with end pieces (5; 18) that point towards each other. Each core angle (3) carries a coil (5; 19) and their mutual spacing is variable by displacing the core angles (3) or the end pieces (5) with respect to the other parts of the iron core. The iron core sections may however also be fixedly linked to each other and core extension pieces (20) may be provided within the heating station between the end pieces (18) on the one side and the insert (12) on the other side.
