[0004] The embodiment of the present application provides a method and device for measuring the degree of intersection of rolling mill rolls, which solves the technical problem in the prior art that when measuring the degree of intersection between rolls, it is necessary to stop the measurement and the measurement result is a static value. In the case of non-stop, dynamically measure the intersection degree between the rolls, avoid affecting normal production, and the technical effect of more accurate measurement results

Embodiment 1
[0054] Such as figure 1 As shown, this embodiment provides a method for measuring the intersection degree of rolling mill rolls, which is applied during the operation of the rolling mill, including:
[0055] Step S101: Obtain the pressure values of the lining plates on both sides of the first bearing seat on the driving side of the upper roll, and the pressure values of the lining plates on both sides of the second bearing seat on the working side of the upper roll.
[0056] In a specific implementation process, the rolling mill involved in this embodiment may be a CVC rolling mill, which includes one or more sets of rolls, and each set of rolls is composed of an upper roll and a lower roll. In this embodiment, the degree of intersection between the upper roll and the lower roll in each set of rolls is mainly measured.
[0057] This embodiment adopts the principle of pressure piezoelectric induction to measure the pressure of the rolling mill roll chocks on the liner (ie:...
Embodiment 2
[0107] Based on the same inventive idea, such as Figure 5 As shown, this embodiment provides a measuring device 300 for the degree of intersection of rolling mill rolls, which is applied during the operation of the rolling mill and includes a memory 310, a processor 320, and a computer stored in the memory 310 and capable of running on the processor 320 Program 311. When the processor 320 executes the program 311, any method step in one of the foregoing embodiments may be implemented.
[0108] In a specific implementation process, the measuring device 300 for the intersection degree of the rolling mill roll system can specifically be figure 2 In the computer (ie: industrial control computer).
Embodiment 3
[0110] Based on the same inventive concept, this embodiment provides a computer-readable storage medium on which a computer program is stored, and when the program is executed by a processor, any method step in the above-mentioned embodiment can be implemented.
[0111] Those skilled in the art should understand that the embodiments of the present invention may be provided as methods, systems, or computer program products. Accordingly, the present invention can take the form of an entirely hardware embodiment, an entirely software embodiment, or an embodiment combining software and hardware aspects. Furthermore, the present invention may take the form of a computer program product embodied on one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) having computer-usableprogram code embodied therein.

Abstract
The invention discloses a method for measuring a cross degree of a rolling mill roll system. The method is applied to the running process of a rolling mill and comprises the following steps that pressure values of lining plates on two sides of a first bearing seat on a transmission side of an upper roll and pressure values of lining plates on two sides of a second bearing seat on a working side ofthe upper roll are acquired; pressure values of lining plates on two sides of a third bearing seat on a transmission side of a lower roll and pressure values of lining plates on two sides of a fourthbearing seat on a working side of the lower roll are acquired; on the basis of the pressure values, the deformation of the lining plates on the two sides of each bearing seat is acquired, and a deviation angle of the upper roll and a deviation angle of the lower roll are acquired; and on the basis of the deviation angle of the upper roll and the deviation angle of the lower roll, the cross degreeof the upper roll and the lower roll is acquired. According to the method, the technical effect of dynamically measuring the cross between the rolls under the condition of no shutdown is realized. Meanwhile, the invention further provides a device for measuring the cross degree of the rolling mill roll system and a computer readable storage medium.
Description
technical field [0001] The invention relates to the field of hot rolling technology, in particular to a method and a device for measuring the degree of intersection of rolling mill rolls. Background technique [0002] For rolling mills, especially CVC (continuously variable crown, continuously variable crown) rolling mills, the intersection between rolls is the main reason for the same plate difference, strip deviation, and wave shape. Stop the machine to measure the degree of intersection between the rolls, and adjust the spatial attitude of the rolls according to the measurement results. [0003] However, at present, when measuring the degree of intersection between rolls, the machine must be stopped for measurement, and the measurement result is a static value, which has technical problems that affect normal production and the measurement result is also inaccurate. Contents of the invention [0004] The embodiment of the present application provides a method and device...
