The guide is a device which is arranged before and after the roll pass in the rolling process of the section steel and helps rolled pieces to accurately and stably enter and exit the roll pass according to a set direction and state.
Guide structures are generally arranged at the inlet and the outlet of a rolling mill in a rolling mill area of a bar and high-speed wire production line workshop to assist the rolling mill in gripping and rolling rolled pieces. The fixation of the guide is generally achieved in two ways: one is a rolling mill upper belt guide beam structure, and the guide is directly arranged on a rolling mill body; the other type is a floor support structure, the guide is independently fixed by a floor guide support, and the center line of the guide of the structure is fixed, so that the adjustment of the guide on a production line is reduced, and the adjustment time is saved.
The existing landing guide support is divided into two types: one is that the landing guide support and the bracket on which the guide is fixed are fixed, when the guide and the roller of the rolling mill are replaced, the guide and the guide bracket need to be hoisted by an overhead traveling crane, the labor intensity is high, and the labor and the time are wasted; the other one is: the guide support is fixed on the foundation, the guide support can rotate around a rotating shaft on the guide support, and the guide support structure with the structure is convenient for the roll change of the rolling mill, is convenient to use and is widely applied. However, the second type of floor stand has the following problems: when the rolling mill changes the roll, the rotation opening degree of the guide bracket is required to meet the requirement of a rolling mill roll changing position, the rotation angle is at least 90 degrees, and the rotation radius cannot be too small, so that the distance between the rolling mills is enlarged, and the total arrangement of the rolling process is influenced; the guide and the support can interfere with a lower cross beam of the rolling mill in the rotating process, so that the rotation is blocked; because the environment of a rolling mill area is severe, a rotating shaft is often rusted and blocked, and the rotating is completed by manually matching with a crown block during rotation, so that labor and time are wasted, and the working efficiency is low; the tilting moment of the guide is larger during rolling, and the rotating shaft of the hollow structure is easy to break.
