摘要

A method for controlling of the melting - or casting operation, in particular dental are precision cast parts, in which the casting material is melted by heating and to a certain point in time (time of casting) a casting of the molten material takes place, characterised in that– on the basis of the desired casting alloy and the amount of the same casting a reference time point, a reference total energy quantity and a reference quantity, at the beginning of energy are selected,– for a specific time interval the of an induction coil for heating of the cast material to be melted is determined by the amount of energy– this quantity of energy then with the same time interval corresponding reference start energy quantity is compared by quotient formation,– a calculated amount of energy is determined by the reference total energy quantity with the quotient is multiplied,– from the calculated amount of energy, which has previously been spent amount of energy is drawn off, and– the time of casting is predetermined by the time still remaining, the to the consumption of the remaining amount of energy is required, is calculated.
