Abstract

본 발명은 고강도 이형봉강 및 그 제조방법에 관한 것으로, 열간압연에 의하여 외경에 나선상 돌기를 갖는 마디압연가공된 콘크리트용 이형봉강 또는 선재의 소재를 상기 열간압연마디가 남는 것같은 감면률로 진원가공(眞圓加工)하고 상기 열간압연된 나선상 돌기의 마디의 나선 비틀림 방향과 반대 비틀림 방향의 복수마디의 나선상 홈을 낸후에 담금질·뜨임열처리를 하여 콘크리트용 철근, 특히 PS콘크리트(prestressed concrete)용 철근으로서 전조나사가공 또는 크로스 와이어 용접등을 하여 사용되고 또 콘크리트와의 부착강도가 필요하게 되는 고강도 이형봉강을 제공하는 것이다.
