Horizontally continuously cast rod of aluminum alloy and method and equipment for producing the rod

Abstract

The invention relates to horizontally continuously cast aluminum alloy rods excellent in quality are efficiently manufactured using a melting / holding furnace ( 101 ) to produce molten aluminum alloy, a molten-metal treatment apparatus ( 201 ) to remove aluminum oxide and hydrogen gas from the molten aluminum alloy, a horizontally continuously casting apparatus ( 301 ) to cast the treated molten aluminum alloy into horizontally continuously cast aluminum alloy rods, a cutting machine ( 408 A, 408 B) to cut to a standard length the cast rods, a first straightening apparatus ( 1001 ) to straighten bend of the cut rods, a peeling apparatus ( 1101 ) to peel skin portions of the straightened rods, a nondestructive inspection apparatus ( 1401 ) to inspect surface and internal portions of the peeled rods, a sorting apparatus ( 1501 ) to sort the inspected rods judged non-defective based on results of the nondestructive inspection step and a packing apparatus to pack the sorted rods, and continuously using at least the first straightening apparatus ( 1001 ).

Description

technical field [0001] The present invention contemplates horizontally continuously cast aluminum alloy rods, and methods and apparatus for making such rods. Background technique [0002] Typically, horizontal continuously cast aluminum alloy rods are manufactured by casting. Specifically, the molten aluminum alloy is cast into an elongated ingot having the form of a cylinder, a square cylinder or a hollow cylinder. The manufacturing method will be described below. [0003] First, raw materials of aluminum alloy are filled into a melting furnace / holding furnace to produce molten aluminum alloy. Alumina and hydrogen are then removed from the molten aluminum alloy using a molten metal handling apparatus. Subsequently, the processed molten aluminum alloy is supplied to a horizontal continuous casting device to thereby manufacture a horizontal continuous casting aluminum alloy rod. Next, the horizontal continuously cast aluminum alloy rod is cut to a predetermined length, an...

Problems solved by technology

[0011] Therefore, it would be difficult to perform a continuous process from start to finish just by interconnecting the devices

[0012] However, in general, since the continuously cast aluminum alloy rod is not continuously supplied to the peeling device, it is difficult for the peeling process to remove the cast surface portion with high productivity.

[0013] Since the production process and the inspection process conduct their respective batch processes separately, the collaboration between adjacent processes is insufficient, and the feedback of the inspection results to the production process contains a time delay

As a result, continuously cast aluminum alloy rods of consistent quality cannot be produced continuously
