摘要：
A method of producing multi-layer metal ingots providing a portion-by-portion filling of metal into the casting mould through liquid slag and crystallization of each portion of metal formed under the liquid slag, the temperature of which is maintained higher than the metal melting temperature of the layer being crystallized under it, each subsequent portion of metal being poured onto the preceding crystallized layer until an interlayer of liquid metal constituting 0.02 to 0.2 of its thickness is maintained over it.
