Description
Technical Field
The utility model relates to an improved structure for solving the problem of crushing of the upper surface of a bearing seat of a supporting roller.
Background
At present, the rolling mill steel plate rolling process mainly realizes roller seam change through EGC screw and nut movement, rolling force is mainly transmitted to an EGC pressure head part, and rolling precision is influenced by the fact that the upper part of a support roller bearing seat is crushed due to long-term multi-pass rolling, particularly impact during steel biting. The replacement of the bearing seat needs to be purchased newly, resulting in increased costs. The utility model is significant in how to solve the problem of crushing the upper part of the bearing seat of the supporting roller and prolong the service life of the bearing seat.
