Abstract
The continuous casting method uses a multistrand type continuous casting apparatus having a plurality of tundishes each provided with a plurality of nozzles for casting strands of at least two different alloys where at least one alloy is cast into two or more strands. The method transfers molten metal into the tundishes from separate ladles corresponding to each tundish, and one tundish feeds at least two water-cooled molds through the nozzles for continuous casting thereof. The number of strands cast for each of the different alloys is determined based on the time required for the preparation of each molten metal, an amount of charge and a casting speed of each molten metal, so as to improve the yield of expensive alloys and/or enhance the rate of operation of the apparatus.
