The wedge tip of the split hole collapsed. The wedge tip of the split hole is sharp, with a rounded corner design of r0.7mm, very low strength, and 1.0mm higher than the roller ring. There are two main reasons for the wedge tip collapse. One is that the pre-splitting wedge of the K4 pass is severely worn, causing a sharp increase in the amount of pressure at the wedge tip of the split hole, resulting in excessive deformation force, causing the split wedge to collapse. The other reason is that the split wedge is higher than the roller ring, and during the transportation and storage of the rolls, there are operational errors and human damage. Due to the split wedge tip falling off, when the next steel is bitten in, the split strip suddenly changes from thin to thick at the falling block, and the split wheel cannot split normally, resulting in steel piling at the split wheel, pushing out the exit guide.
