METHOD OF REGULATING COMPOSITION OF MOLTEN METAL DURING CONTINUOUS CASTING AND APPARATUS THEREFOR

摘要

A method of controlling composition of a molten copper or a molten copper alloy during continuous cast, comprising the steps of determining continuously specific resistance of the molten copper or the molten copper alloy; calculating the composition of the molten copper or the molten copper alloy based on relationships between specific resistance of the molten copper or the molten copper alloy and each constituent which are preliminarily comprehended; and controlling the composition of the molten copper or the molten copper alloy based on the calculated composition. It is possible to consider temperature or content of dissolved oxygen to calculate the composition.
