| Zusammenfassung: | The invention relates to a method for controlling the proportion of aluminum crystals in a mixture of molten aluminum alloy and aluminum crystals. The electrical resistance of the mixture is determined with the aid of a four-point measurement. With the aid of the measured electrical resistance, the proportion of crystals in the mixture can be kept constant within narrow margins. The invention also relates to a device for carrying out the method. |
