Abstract

본 발명은 스텐레스 열간압연 강판을 제wh하는 방법에 관한 것으로써, 열연강판의 조질압연시 강판의 표면조도를 적절히 제어함으로써, 종이압착불량 발생율을 현저히 저감시킬 수 있는 스텐레스 열연강판의 제조방법을 제공하고자 하는 것이다.The present invention relates to a method for removing a stainless hot rolled steel sheet, and by appropriately controlling the surface roughness of the steel sheet during the temper rolling of the hot rolled steel sheet, to provide a method for manufacturing a stainless hot rolled steel sheet that can significantly reduce the occurrence of paper crimp defects I would like to.

본 발명은 스텐레스강을 열간압연한 다음, 열연소둔, 탈스케일 처리, 산 세한후, 권취하여 스텐레스 열연강판을 제조하는 방법에 있어서, 상기 산세후 권취전에 강판의 표면조도 Rmax가 23㎛이하, Rz가 20㎛이하가 되도록 조질압연하여 종이 압착불량 발생율을 저감시킬 수 있는 스텐레스 열연강판의 제조방법을 그 요지로 한다.The present invention is a method for producing a stainless hot rolled steel sheet by hot rolling the stainless steel, followed by hot rolling annealing, descale treatment, pickling, and after the pickling, the surface roughness Rmax of the steel sheet is 23㎛ or less, Rz The manufacturing method of the stainless steel hot rolled sheet which can be temper-rolled so that it may be less than 20 micrometers and can reduce the paper crimping | compression-defective rate is made into the summary.
