The Burr After Side Trimmer In Hot Rolling Pickling Line Reason Analysis

BOYA steel/ sheet shearing machineis one of the key equipment of pickling line or PLTCM. The metal trimming/ shearing machine function is to trim the edge of raw materials according to the width of finished products and remove the quality defects of raw materials .For example Burr refers to the raw material in the edge-cutting treatment, the appearance of "hair-like" quality defects at the edge of the strip. Its harm is that the burrs are easy to cause the strip broken in rolling process; A good cut can avoid defects such as burrs, which may cause quality problems during rolling. The main reasons for burrs are:

Hot rolling raw material defects

Uneven width, edge wave, edge wrinkle, edge crack and other quality defects of hot rolling raw materials will impact the blade edge of the trimming, resulting in the blade edge collapse, or lead to the trimmer edge cutting failure or slip blade, resulting in burr

The clearance calculation has changed

The shear Gap is determined by both Gap and Lap. The mathematical model used for clearance calculation is based on the theoretical cross-section of hot rolled material. The theoretical hot rolling material has good consistency of cross-section, few edge drop and no wedge. In fact, the cross-section structure of hot rolling materials used in cold rolling mills of various steel mills is not the same, and hot rolling materials have their own unique cross-section structure, so there is a deviation between theory and practice

Clearance calibration is not accurate

Trimming edge gap jump

The gap jump of the trimming edge is produced by the coordination of upper and lower cutting edges. The cutting edge is fixed on the shaft head of the cutting seat by the hydraulic nut, and the expansion ring is pressed outward by the locking screw. When the hydraulic nut is not properly fastened, the axial force is insufficient in the process of vertical strip cutting edge, resulting in the axial jitter of cutting edge and the jump of cutting edge gap.
