Abstract:
1. A method for manufacturing horizontally continuously cast aluminum alloy rods, comprising: a melting step of melting raw material for aluminum alloy to produce molten aluminum alloy; a molten-metal treatment step of removing aluminum oxide and hydrogen gas from the molten aluminum alloy received from the melting step; a horizontally continuously casting step of casting the molten aluminum alloy received from the molten-metal treatment step into horizontally continuously cast aluminum alloy rods; a cutting step of cutting to a standard length the horizontally continuously cast aluminum alloy rods cast in the horizontally continuously casting step; a conveying step of conveying the cut, horizontally continuously cast aluminum alloy rods; a first straightening step of straightening bend of the conveyed, horizontally continuously cast aluminum alloy rods; a peeling step of peeling skin portions of the straightened, horizontally continuously cast aluminum alloy rods; a nondestructive inspection step of inspecting surface and internal portions of the horizontally continuously cast aluminum alloy rods having the casting surface portions peeled; a sorting step of sorting horizontally continuously cast aluminum alloy rods judged non-defective based on results of the nondestructive inspection step; and a packing step of packing the horizontally continuously cast aluminum alloy rods judged non-defective, with all steps being continuously performed.
