After the Ø550×6 (H/V) roughing mill 6# and the Ø420×6 (H/V) rolling mill 12#, each of the start-stop flying shears are used to cut and cut the rolled parts. Accident cut (all bars and rods are used); after the Ø320×6 (H/V) finishing mill 18#, there is one start-stop type double-fold flying shear to the rolling section (for bars).
