Abstract:
1. A method of controlling a chemical composition of a molten copper alloy in continuous casting, comprising the steps of: providing at least one molten alloying element at a high concentration, adding said at least one molten alloying element to pure molten copper at a variously set known ratio, to obtain a respective specific resistance of a first molten copper alloy, thereby obtaining a relationship between a chemical composition of the first molten copper alloy and the specific resistance of the first molten copper alloy, the first molten copper alloy containing said at least one molten alloying element at a given concentration; continuing to add the at least one molten alloying element to the pure molten copper to form a second molten copper alloy; continuously determining a specific resistance of the second molten copper alloy during continuos casing; calculating the chemical composition of the second molten copper alloy, based on the obtained relationship the determined specific resistance of the second molten copper alloy and an amount of said at least one molten alloying element; and adjusting the chemical composition of the second molten copper alloy, based on the calculated chemical composition of the second molten copper alloy, by changing the amount of said at least one molten alloying element being added.
