As the market's requirements for the quality of cold-rolled strip continue to increase, higher-grade cold-rolled strip not only has high requirements on its own performance, but also requires the surface of the steel strip to be beautiful and free of scratches, otherwise the steel coil will be downgraded, and steel coils with severe scratches may be scrapped.

[0003] After the cold-rolled steel strip is coiled, the core and head of the steel coil will sink, which will hinder the lifting of the steel coil and damage the surface of the steel coil. Therefore, the core and head of the steel coil need to be fixed.

[0004] Existing methods include sticking tape, spot welding or installing guard rings on both sides. Among them, sticking tape has the problem of not sticking firmly, and because the tape is disposable, it is relatively wasteful, and there will be glue marks after the tape is removed, which is time-consuming to remove. Spot welding has the problem of complex operation, and the strip steel at the welding part will be damaged. Installing guard rings on both sides has the problem of occupying a large space due to the large size of the guard rings.

[0005] Therefore, a steel coil core head fixing device with better application effect is needed. Summary of the invention
