in automatic melting crucible tipping it is important that , starting from a certain angular position , the melting crucible 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 . in order to prevent abrupt movement of the crucible when the molten material touches the pouring lip of the crucible when the pour - lip angle has been reached , according to the invention a correction arrangement is provided which enables the tipping process to proceed continuously and without abrupt movements even in the case of different pour - lip angles .
