Abstract
A method and a device control the introduction of several metals into a cavity configured to melt the metals in the form of ingots. In particular, the method is configured to control the introduction of several metals into a cavity for melting the metals so as to dip-coat a steel strip with the metals in liquid metal form. Whereby a first metal is introduced in the form of at least a first ingot having a high content of the first metal and a second metal is introduced in the form of at least a second ingot formed as an alloy of the first metal and the second metal. The second metal content of the second ingot is chosen from a range of significant contents for ensuring an intended overall flow rate for combined melting of the ingots, the range of significant contents being chosen in a limited interval of sequentially increasing values so as to minimize differences between melting points of the ingots.
