In the paper, such problems as improper shearing parameters adjustment, nonstandard replacement process of shear blades, jam of scrap edge and poor running of belt in the shearing process with circle shear of galvanizing unit in Cold Rolled Rare Earth Steel Plate Plant of Baotou Steel are mainly elaborated, which cause the normal edge trimming of production line to be incapable as required or poor edge trimming so that the improvement of first pass yield and normal delivery within delivery cycle of products with main production line are affected. In order to improve the edge trimming quality of circle shear as well as ensure continuous stable and high production, the experiment is carried out to ensure stable operations and edge trimming quality of shearing process with circle shear.
