Control method and system of side guide plate

Abstract

The invention discloses a control method and a system of a side guide plate. By controlling of an action process of the side guide plate, so that the side guide plate can always move to a target opening degree in the same direction when being opened or closed, so that a mechanical gap is always concentrated on the same side, and the influence of the mechanical gap on a final opening degree of theside guide plate is eliminated; and a centering effect and threading stability of strip steel are improved, and then the rolling precision of the strip steel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of rolling, in particular to a control method and system for a side guide plate. Background technique [0002] The guide plate on the entrance side of finish rolling plays a vital role in guiding the strip head during the strip threading process. It directly determines the biting state of the strip head, thus affecting the stability of the strip head. As we all know, after the mechanical side guide plate is used for a period of time, due to impact and wear, there will be a certain gap at the connection between the side guide plate and its linkage mechanism, which directly interferes with the accuracy of the opening degree of the side guide plate. The influencing formula is as follows: [0003] act gap =Set gap ±Δ_Space [0004] Among them, Act gap is the final opening of the side guide, Set gap is the set opening of the side guide, and △_Space is the actual space of the side guide. [0005] In the open...
