Detailed Description
The application will now be described in further detail with reference to the accompanying drawings. In the description of the present application, it should be understood that the terms "left", "right", "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the apparatus or element being referred to must have a specific orientation, be configured and operated in a specific orientation, and "first", "second", etc. do not indicate the importance of the components, and thus are not to be construed as limiting the present application. The specific dimensions adopted in the present embodiment are only for illustrating the technical solution, and do not limit the protection scope of the present application.
As shown in fig. 1 and 2, the method for turning the wide and thick plate in advance of the application comprises the following steps:
s1, setting two groups of flat roller tables, namely an A group roller table and a B group roller table, wherein blanks are conveyed from the A group roller table to the rolling mill, and the B group roller table is a group of reversing roller tables which can be opposite to the A group roller table.
S2, a rolling system of a wide and thick plate is adopted, wherein the rolling system comprises a primary automatic control system and a secondary computer control system, and an advanced steel conversion mode is a functional interface added based on a wincc system;
the operator is responsible for whether the advanced steel turning function needs to be used or not:
if the steel is not required to be turned, the advanced steel turning function key is not checked in the HMI window;
if the steel is required to be turned, a preset steel turning function key is checked in an HMI window, a secondary computer control system is triggered, whether the steel plate meets the steel turning condition or not is judged, the steel turning bar piece comprises a steel plate with a diagonal value smaller than the width of a transmission track of a rolling mill and the head of a blank is positioned in front of a B group of roller ways, the rolling mill conveying roller way is set to be 5m, and the diagonal value of the steel plate is smaller than 4.75m;
if the conditions are met, after the first stage receives the second stage regulation, the roller way of the group B is controlled to rotate reversely, and the speeds of the roller ways of the group A and the roller ways of the group B are 1.0m/s; if the diagonal value of the steel plate is larger than the width of a transmission track of the rolling mill and/or the head of the blank is not in front of the roller way of the group B, the first-level automatic control system does not generate a steel conversion condition, the roller way of the group B and the roller way of the group A turn to the same direction, the steel plate is not affected by any influence, and the steel plate is normally transported to the rolling mill to be rolled.
S3, controlling an operator handle, wherein the handle is one of control equipment of an operation table and is used for controlling the roller way to move forwards or backwards, the operator keeps the inertia of the blank to move forwards through the handle, and the head of the blank starts to rotate after contacting with the roller way of the group B.
Under the action of inertia, a part of the head of the blank enters the roller way of the group B, at the moment, most of the blank still remains in the roller way of the group A, and the directions of friction forces applied to the lower surface of the blank on the roller way of the group A and the roller way of the group B are different. Because the lower surface of the blank is different in the contact surface sizes of the roller ways of the group A and the roller ways of the group B, the friction force of the blank in the roller way area of the group A is obviously larger than that of the roller way of the group B. The directions and the sizes of friction forces applied to different areas of the blank are different, so that deflection parallel to the roller way surface is generated, the deflection direction is controlled by the central line of the blank during tapping, and the deflection direction is deviated to one side of the central line of the roller way. The steel plate can be stopped on the roller way of the group A after transversely rotating steel through repeated back and forth friction between the roller way of the group A and the roller way of the group B.
S4, after the steel is turned, controlling the roller way of the group B to rotate positively, and conveying the steel plate after the steel is turned to the direction of the rolling mill.
