Abstract
Description
The present invention relates to a method for adjusting a roll of a reversing tandem mill (RTM) that can facilitate fine adjustment of a roll for removing a deviation.
In general, in order to produce a rolled material in a steel mill, a rolling process is performed, and the rolling process is performed by inserting slabs, blooms, billets, etc., produced in a continuous casting process, between two rotating rolls to form a thin and long shape. will be.
The rolling mill is a device for forming a plate, a bar, etc. through plastic deformation of the material while passing the material between the rolls rotating at room temperature or high temperature. A transfer guide is installed between the rolling mill and the rolling mill to transfer the rolled material to the rolling roll side of the next step.
The present invention, in the reversible tandem rolling mill, to provide a method for adjusting the roll of the reversible tandem rolling mill, to conveniently remove the deviation caused after adjusting the zero point or the gap between the rolls by changing the specification of the final product will be.
Roll control method of the reversible tandem rolling mill according to an embodiment of the present invention, for the zero control of the vertical roll and horizontal roll of the reversible tandem rolling mill, or change the specifications of the final product produced by the reversible tandem rolling mill Changing the spacing of the rolls in order to achieve this; Displaying a fine adjustment menu for finely adjusting the vertical roll and the horizontal roll; And finely adjusting the vertical roll and the horizontal roll through the fine adjustment menu.
According to an aspect of an embodiment of the present invention, the fine adjustment menu includes a horizontal roll input box and a vertical roll input box, and the vertical roll and the horizontal roll is finely adjusted through the fine adjustment menu When the fine adjustment value is input to one of the up and down horizontal roll input fields, the up and down horizontal roll may include adjusting finely by the fine input value.
According to an aspect of an embodiment of the present invention, the fine adjustment menu includes a horizontal roll input box and a vertical roll input box, and the vertical roll and the horizontal roll is finely adjusted through the fine adjustment menu When the fine adjustment value is input to one of the left and right vertical roll input fields, the left and right vertical rolls may include fine adjustment by the fine input value.
According to an embodiment of the present invention, the fine adjustment value may be input through a user input unit.
According to one embodiment of the present invention having the above-described configuration, it is possible to conveniently and quickly adjust the deviation generated in the reversible new temper rolling mill. That is, the centerline adjustment time can be shortened and fewer errors can be generated during data modification. Mistakes that can occur when modifying data can be prevented.
1 is a flow chart for explaining the roll adjustment method of an embodiment of the present invention, a reversible tandem rolling mill.
Figures 2a and 2b is a view for explaining the fine adjustment menu used in the roll adjustment method of the reversible tandem rolling mill of one embodiment of the present invention.
Hereinafter, a method of adjusting a roll of a reversible tandem rolling mill according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the present specification, the same or similar reference numerals are assigned to the same or similar configurations in different embodiments, and the description thereof is replaced with the first description.
1 is a flowchart illustrating a roll control method of an reversible tandem rolling mill according to an embodiment of the present invention.
As shown, first, the gap of the rolls are changed in order to zero the vertical and horizontal rolls of the reversible tandem rolling mill or to change the specifications of the final product produced by the reversible tandem rolling mill (S1). . Next, a fine adjustment menu for finely adjusting the vertical roll and the horizontal roll of the reversible tandem rolling mill is displayed (S3). Then, fine adjustment of the vertical roll and the horizontal roll through the fine adjustment menu (S5). Here, the fine adjustment menu includes a left and right horizontal roll input box, and a vertical roll input box, and when the fine adjustment value is input to one of the vertical roll input box, the vertical horizontal roll is finely adjusted by the fine input value. Can be. Meanwhile, the fine adjustment menu includes left and right horizontal roll input boxes and up and down vertical roll input boxes, and when fine adjustment values are input to one of the left and right vertical roll input boxes, the left and right vertical rolls are finely adjusted by the fine input values. It may comprise the steps. The fine adjustment value is input through the user input unit.
To this end, a detailed fine adjustment menu will be described in detail with reference to FIGS. 2A and 2B.
Figure 2a and 2b is a view for explaining the fine adjustment menu used in the roll adjustment method of the reversible tandem rolling mill according to an embodiment of the present invention, Figure 2a is a fine adjustment menu to adjust the zero point after kissing, Figure 2b is This menu is for adjusting roll interval for changing the standard.
In order to explain the drawings, terms displayed on the adjustment menu will be described. First, a reversible tandem rolling mill consists of three stands: That is, it may be configured as UF: Universal Finishing stand, EDGER: Edger stand, UR: Universal Roughing stand. Each of the three stands is driven by a large rolling mill motor.
In the figure, HOR stands for horizontal roll as an abbreviation of Horizontal, NDS stands for non-load side, and means half load side, and DS stands for load side as an abbreviation for Drive Side.
The fine adjustment menu for zero adjustment after kissing will be described with reference to FIG. 2A. As shown in FIG. 2A, a fine adjustment menu for zero adjustment after kissing is displayed with a
The adjustment value may be input by a user who has recognized the value after actually measuring the horizontal roll and the vertical roll. As such, if the zero point adjustment is performed through the
After the product specification changes, if the initial rolled product falls short of the specification, the gap between the rolls should be adjusted.
First of all, if the product specification is changed, do the initial rolling and check the product specification. At this time, if the initial product conforms to the product specification, the rolling process is continuously executed. If the modified product initially rolled does not meet the product specification, gap adjustment is performed.
Hereinafter, a fine adjustment menu for gap adjustment will be described with reference to FIG. 2B.
As shown in FIG. 2B, the fine adjustment menu for zero adjustment after kissing is displayed with a
The adjustment value may be input by a user who has recognized the value after actually measuring the horizontal roll and the vertical roll. When zero adjustment is performed through the
Roll control method of the reversible tandem rolling mill as described above is not limited to the configuration and operation of the embodiments described above. The above embodiments may be configured such that various modifications may be made by selectively combining all or part of the embodiments.
