1, mends bundle at the scene.After the bundle of loosing,, must in time mend bundle for preventing that the loose winding number of turns from continuing to enlarge.
2, excision loose winding part.Because the coil of strip outer ring elasticity of this thickness is less, to loose after the bundle, the number of turns of loose winding is less.Such coil of strip can excise the part of outer ring loose winding, and then mends bundle.
3, go up the reparation of finishing rewinding line.Because the coil of strip thinner thickness that 6mm is following, and the bundle back coil diameter of loosing is less, can repair by above finishing rewinding line.
The shortcoming of above-mentioned prior art is as follows:
The coil of strip thinner thickness that 6mm is following, coil of strip outer ring elasticity is less.Loose after the bundle, the number of turns of loose winding is less, and can repair by above finishing rewinding line, but the reparation difficulty of the slab loose winding more than the 6mm is bigger.On the one hand, because slab outer ring elasticity is big.Behind the slab loose winding, the number of turns of loose winding is many, surpasses the maximum coil of strip external diameter scope that equipment allows.On the other hand, some slab loose windings have exceeded the thickness specification limit of finishing rewinding line.So the slab loose winding generally can not be reached the standard grade and be repaired, can only do and scrap or the processing of demoting, the economic loss that causes is huge.
At present known hot rolling is produced line after slab loose winding accident takes place, and also coil of strip can only be scrapped or the processing of demoting, and does not have effective processing method.
