Abstract

본 발명은 제철소의 스테인레스 열간압연공정중 가열로에서 스테인레스 슬라브 표면에 형성된 가열로스케일(Scale)을 스팀블로워 및 고압수 스케일제거장치를 이용하여 효과적으로 제거시킴으로서 우수한 표면품질의 스테인레스 열연강판을 제조하기 위한 발명된 스테인레스 슬라브 표면의 가열로스케일 제거방법에 관한 것이다.The present invention effectively removes the scale of the heating furnace (Scale) formed on the surface of the stainless slab in the heating furnace during the stainless steel hot rolling process of the steel mill using a steam blower and a high pressure water descaling device for producing a stainless hot rolled steel sheet of excellent surface quality The invention relates to a method for removing a furnace scale on the surface of a stainless slab.

본 발명은 스테인레스 슬라브 표면의 가열로스케일 제거방법은 가열로에서 추출된 스테인레스 슬라브를 폭압연하여 슬라브 표면의 가열로스케일층에 크랙을 생성시킨다음 고압수탈스케일 장치에 의해 슬라브 표면의 스케일을 박리시키는 스테인레스 슬라브 표면의 가열로스케일 제거방법에 있어서, 상기 스테인레스 슬라브를 폭압연하기 전에 폭압연를 입측에 설치된 스팀 블로워로 스팀을 분사하여 가열로스케일의 온도를 700∼900℃로 냉각시킨다.In the present invention, the method for removing the furnace scale on the surface of the stainless slab is to generate a crack in the furnace scale layer on the surface of the slab by rolling the stainless slab extracted from the furnace and then peeling off the scale on the surface of the slab by a high pressure dehydration scale apparatus. In the method of removing a furnace scale on a surface of a stainless slab, steam is sprayed with a steam blower installed at the mouth side of the furnace before it is rolled, thereby cooling the temperature of the furnace scale to 700 to 900 ° C.
