Abstract

본 발명은 건축용 및 기계구조물에 주로 사용되는 형강의 제조방법에 관한 것으로써, 좀더 구체적으로는 냉간압연에 의해 조직이 치밀한 형강을 얻을 수 있도록 한 것이다.The present invention relates to a method for manufacturing a shaped steel mainly used for building and mechanical structures, and more specifically, to obtain a dense shaped steel structure by cold rolling.

이를 위해, 절곡되는 부위를 제외한 나머지 두께를 감소시켜 덧살(2)이 형상되도록 하는 1차 압연공정과, 상기 덧살부위의 중심을 경계로 하여 절곡하여 성형공정과, 상기 절곡된 형강의 덧살부위를 압연하여 모서리부분을 직각상태로 성형하는 2차 압연공정을 순차적으로 진행하여 형강을 얻는다.To this end, the primary rolling process for reducing the thickness of the remaining portion except for the bent portion (2) to form the shape, the bending process by bending the boundary of the center of the portion of the shaping portion and the portion of the bent portion of the bent steel Secondary rolling process of rolling and forming corners at right angles is sequentially performed to obtain a shaped steel.
