Abstract

본 발명은 아연도금조 소재로 사용되는 강판의 제조방법에 관한 것이며, 그 목적은 용융아연 도금환경 내에서 고온 내부식성이 우수한 도금조용 강판의 제조방법을 제공하고자 하는데 있다.The present invention relates to a method for manufacturing a steel sheet used as a galvanizing bath material, and its object is to provide a method for producing a steel sheet for a plating bath excellent in high temperature corrosion resistance in a hot dip galvanizing environment.

본 발명은 아연도금조에 사용되는 구조용강판을 제조하는 방법에 있어서, 중량 %로, C:0.003~0.06%, Mn:0.2~0.4%, Si:0.05% 이하, P:0.010% 이하, S:0.005%이하, 잔부 Fe 및 기타 불가피한 이루어진 강슬라브를 통상의 방법으로 재가열후 압연형상비를 0.7이하로 하여 저속강압하 하는 고온 내부식성이 우수한 아연도금조용 강판의 제조방법에 관한 것을 그 기술적 요지로 한다.The present invention is a method for producing a structural steel sheet used in the galvanizing bath, in weight%, C: 0.003-0.06%, Mn: 0.2-0.4%, Si: 0.05% or less, P: 0.010% or less, S: 0.005 The technical gist of the present invention relates to a method for manufacturing a steel plate for galvanizing bath having excellent high temperature corrosion resistance, in which a rolling aspect ratio of less than%, balance Fe, and other unavoidable steel slabs is reheated by a conventional method to 0.7 or less, followed by low-speed rolling.
