Why Burr Appears After Side Trimmer in Hot Rolling Pickling Line


BOYA coil shearing machine is one of the key equipment of pickling line or PLTCM. The sheet cutting 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.


Showcasing the Advantages of Boya Metal Trimming Machine


Our Metal Side Trimming/Shearing Machine uses an advanced control system to ensure the accuracy and consistency of each shearing. This makes it excel in edge trimming and shearing of various metal materials.


The equipment uses high-quality materials and manufacturing processes to ensure its long life and reliability. Whether it is steel, aluminum or copper, it can handle it easily.
