| titleOfInvention | Dull roll for cold rolling metal sheet and method for producing the same |
| abstract | The present invention provides a dull roll for cold rolling of a metal plate that can easily obtain a desired surface property of a roll in a short time, and that can change a roll surface roughness with a rolling distance and improve a roll basic unit. The dull roll for cold rolling of the present invention has a chromium plating layer composed of an upper layer plating and a lower layer plating on the surface of an under roll having a Vickers hardness of 600 or more, and an upper layer plating of the chromium plating layer And Vickers hardness HV0.025 of the lower layer plating is 850 or more and 650 to 950, respectively, and the chromium plating layer surface has an arithmetic average roughness Ra of 0.3 μm or more and the number of peaks per inch of length. It is characterized by 200 or more PPI. Moreover, the method for producing a dull roll for cold rolling according to the present invention has an arithmetic average roughness Ra of 0.35 μm or more on the surface of the base roll having an arithmetic average roughness Ra of 0.05 to 2.0 μm, and a length of 1 A first plating layer having a peak number PPI per inch of 230 or more is formed, an arithmetic average roughness Ra is 0.3 μm or more, and a peak number PPI per inch of length is 200 or more. Two plating layers are formed. [Selection] Figure 5 |
