Improvement apparatus of surface roughness defect of hot/cold rolled stainless steel coils and the method thereof

Abstract

Disclosed is to an improvement apparatus of surface roughness of hot/cold rolled stainless steel coils and the method thereof. The present invention provides an improvement apparatus of surface roughness of hot/cold rolled stainless steel coils including a water spray unit for spraying water on a surface of a cast stainless steel slab; a cutting unit for cutting the stainless steel slab; and a high-pressure water spray having at least one nozzle in a region where the stainless steel slab is cut by the cutting unit and discharged and installed to be symmetric in upper and lower parts of the stainless steel slab; and a roller brush installed to be in contact with and symmetric in the upper and lower parts of the stainless steel slab passed through the water spray so as to rotate at a high speed. Accordingly, the improvement apparatus according to the present invention may be useful to produce a stainless steel slab having an excellent surface quality since it is possible to easily remove the scale and mold slag from the stainless steel slab.
