Claim:
Method for the exactly weight-controlled filling of ingot molds of a nonferrous casting machine, for example, a copper anode casting machine or a zinc anode casting machine, which is designed in the form of a fully mechanized casting operation with at least one casting wheel and is equipped with ingot molds, the method comprising the steps of: introducing molten metal into an intermediate trough ( 4 , 4 ′) at a regulated mass flow rate with simultaneous determination of the continuous dynamic weight increase; feeding molten metal alternately into metering troughs ( 5 , 5 ′) located on either side of the intermediate trough ( 4 ) by tilting the intermediate trough ( 4 ) first to one side and then to the other, and after the first metering trough ( 5 ) has been filled, tilting the intermediate trough ( 4 ) towards the second metering trough ( 5 ′), and at the same time casting the mass of an anode from the metering trough that was filled first into one of the ingot molds ( 10 , 10 ′) located on the casting wheel ( 9 , 9 ′) by a controlled tilting movement; and dividing the mass flow during casting into three phases, such that, in a first phase, the casting material is first cast into an ingot mold at a relatively low mass flow rate; in a second phase, after a predetermined metal mass or metal weight has been reached, uniform filling of the ingot mold ( 10 ) at a relatively higher mass flow rate is undertaken; and, in a third phase, after a predetermined weight of molten metal has again been reached, slow filling at a reduced mass flow rate is carried out to obtain the precise weight desired.
