Precision Influence of Sickle-Like Curve of Hot Rolled Strip on Rotary Shear's Cutting

Abstract:

Push-pull pickling line of a branch of WISCO frequently comes up the faults that rotary shear axial locking is unreliable and the cutting precision is low. To solve this problem, two kinds of sickle-like curve have been analyzed, the graphic method and the finite element method were used. The research come to the conclusion that frequent appearance sickle-like curve would produce additional axial impact load on rotary shear's shear blade and also calculated value of axial static load. These are the main reason why the faults appear. After took the proposed solutions accordingly to improve the locking force, the down time were greatly reduced and the cutting precision were improved significantly.
