Abstract

본 발명은 금속표면이 있는 길이방향으로 연신되는 봉강재료를 자석에 의하여 구동되고, 봉강이 축 둘레를 회전하는 아크에 의하여 표면열처리하는 방법 및 장치에 관한 것으로서, 여기에서는 아크가 환상전극(양극)과 이 양극을 통하여 안내되고, 음극으로 이용되는 봉강 사이에서 움직인다.
본 발명에 있어서, 아크의 안정화를 위한 개선된 방법을 개발하는 문제는 봉강의 진행방향으로 환상전극의 뒤쪽에 배치되어 있는 직류자석에 의하여 아크를 회전시키고, 이와 동시에 직류자석에 의하여 감응되는 자장이 아크의 수직선 발이 이동하는 봉강에 따라 가려는 동행작용에 역작용을 하고, 환상전극의 전류를 2개의 분류로 분할함으로써 해결한다.
사용번위는 무엇보다도 금속표면이 있는 길이방향으로 연신되는 봉상재료의 표면을 열처리하는데 있다.
