Embodiment Construction

[0018] The technical solution of the present invention will be further described in detail below in conjunction with the description of the drawings and specific embodiments.

[0019] Such as figure 1 As shown, a method for controlling the speed of the cooling bed input roller table is carried out based on the control system and a plurality of continuous roller tables 1, wherein the plurality of roller tables 1 constitute the cooling bed input roller table, and the control system controls each roller table The rotational speed of the driving device in 1 and the motion state of the monitoring flying shear 2 are specifically implemented according to the following steps:

[0020] Step 1, setting the normal lead coefficient of each roller table 1 speed according to the line speed of the rolling mill 4, and setting the sub-steel lead coefficient of each roller table 1 according to the specification of the steel material 3;

[0021] Step 2, before the flying shear 2 sends out a she...

Abstract

The invention discloses a control method of the cooling bed entry table speed. The method is implemented specifically according to the following steps that the normal-state advancing coefficient of the speed of each roll table is set according to the linear speed of a rolling mill, and the steel bar splitting advancing coefficient of each roll table is set according to the specification of a steelmaterial; before a flying shear sends a shearing signal, a control system controls the rotating speed of each driving device, and the effect that the speed of each roll table is kept in the normal-state advancing coefficient all the time is guaranteed; after the flying shear sends a shearing signal, before the tail of the steel material is separated from a track, the control system controls the rotating speed of each driving device, and the effect that the speeds of corresponding roll tables is kept in the steel bar splitting advancing constant all the time is guaranteed; and after the tail of the steel material leaves the corresponding roll tables, the control system controls the rotating speed of each driving device, and thus the speeds of the roll tables are restored to the normal-state advancing coefficient. By means of the method, the problem which happens to control over the advancing amount of the cooling bed entry table speed is solved.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to a method for controlling the speed of an input roller table of a cooling bed. Background technique [0002] In steel production, the efficiency of the cooling bed input roller table to transport finished steel is a key assessment index for increasing steel production, reducing maintenance intensity, and reducing the consumption of spare parts for roller tables. [0003] Among them, in the production process of the rolling line, after the finished steel frame is cut by flying shear, the acceleration of the segmented steel is carried out by the cooling bed input roller table, and the linear speed of the roller table is generally higher than the linear speed of the final frame of the rolling line. There is an advance amount, which is to use this advance amount to draw a certain distance between the segmented steel and the rear steel to ensure that the segmented ...
