Brief Introduction of Packaging Steel Strip Slitting Line

Brief Introduction of Packaging Steel Strip Slitting Line
　　The slitting line in the hot rolling finishing zone is used to longitudinally slit the hot rolled strip. In the past, narrow strip steel coils were directly produced on hot strip rolling mills, but with the increase in the width and production capacity of strip hot strip rolling mills, special slitting operations for slitting hot strip steel coils into narrow strips have been installed. line.
　　 The narrow strip cut from the slitting line is used as a blank for welded pipes, cold-formed californium, etc.
　　Slitting line is composed of coiling, uncoiling, tension coiler and other equipment. Figure 2-57 and Figure 2-58 are its typical layout.
　　The hot-rolled strip coil supplied to the slitting line is 1.2-13mm thick and 600-2200mm wide. The operating line capacity is 90-150 tons/hour, and the shear speed is 90-150 m/min.
　　 In order to improve the ability of slitting shear, the shearing method is being further improved, and the shearing speed has reached 400 m/min recently. In order to shorten the adjustment and replacement time, the offline pre-adjustment replacement method tends to replace the current online adjustment method.
