Abstract

본 발명은 드로잉과 아이어닝을 실시하는 2-피스 캔용 표면처리 원판의 제조방법에 관한 것으로써, 극저탄소강에 강력한 탄질화물 형성원소인 Ti을 일정수준으로 첨가하여 연속소둔함으로써 가공성 향상 및 소부경화특성을 이용하여 강도를 증가시킨 소부경화형 열질표면처리원판을 제조하고자 하는데, 그 목적이 있다.The present invention relates to a method for manufacturing a two-piece can surface treatment disc for drawing and ironing, and to improve workability and harden the sintering by adding a certain level of Ti, a powerful carbonitride-forming element, to an ultra low carbon steel at a constant level. The purpose of the present invention is to fabricate a hardening type thermal surface treatment disc having increased strength by using properties.

본 발명은 전(total) 산소를 12ppm 이하 함유하는 강을 출발소재로하여 연질 표면처리 원판을 제조하는 방법에 있어서, wt%로, C : 0.005%이하, Ti : 0.01-0.03%, SoㆍAl : 0.02-0.06%, Si : 0.02%이하, Mn : 0.1-0.2%, P : 0.015%이하, S : 0.015%이하, N : 0.003%이하, 잔부 Fe 및 기타불가피한 불순물로 조성되는 Ti 첨가 극저탄소 Al 탈산강을 통상의 방법으로 연간압연 및 산세한 다음, 85-90%의 냉간압하율로 냉간압연하고, 700-740℃의 온도구간에서 소둔한 후 조질압연하는 소부경화형 연질표면처리 원판의 제조방법을 그 요지로 한다.The present invention relates to a method for producing a soft surface treatment disc using a steel containing 12 ppm or less of total oxygen as a starting material, wherein wt: C, 0.005% or less, Ti: 0.01-0.03%, and So.Al : 0.02-0.06%, Si: 0.02% or less, Mn: 0.1-0.2%, P: 0.015% or less, S: 0.015% or less, N: 0.003% or less, Ti-added ultra low carbon composed of residual Fe and other unavoidable impurities Preparation of the hardened hardened surface treatment disc which is rolled and Al-oxidized steel by the usual method, annually, then cold-rolled at 85-90% cold reduction rate, and annealed at 700-740 ° C temperature range. That's the point.
