ABSTRACT:
In automatic melting crucible tipping it is important that, starting from a certain angular position, the melting crucible (1) is tipped according to a predetermined model until emptying is complete. This model can be obtained, for example, by the so-called teach-in process and can be stored in an analog or digital memory (89). In order to prevent abrupt movement of the crucible (1) when the molten material touches the pouring lip (3) of the crucible (1) when the pour-lip angle has been reached, according to the invention a correction arrangement (108, 109, 37) is provided which enables the tipping process to proceed continuously and without abrupt movements even in the case of different pour-lip angles.
