Description

Technical Field

[0001] The utility model relates to the field of steel production, in particular to a lower roller system elevation device. Background Art

[0002] The roll system of the hot rolling production line usually consists of a support roll and a working roll on the top and bottom. The support roll supports the working roll during the rough and finish rolling of the strip. The working roll can reduce the diameter of the working roll and enhance the rigidity of the working roll by contacting the rolled piece to prevent the working roll from bending and deforming during the strip rolling process, which affects the quality of the strip. The existing control technology of the hot coil production line of the rolling mill does not have a method for calculating the elevation of the lower roll system for rough rolling and finishing rolling. After the rough rolling and finishing rolling work rolls are replaced, the operator cannot confirm whether the setting of the number of lower step pads is reasonable through the actual elevation of the lower roll system.

[0016] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0017] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0018] See also Figure 1 , Figure 1 The schematic diagram of the structure of the lower roll system elevation device in one embodiment of the present application. The utility model provides a lower roll system elevation device, which comprises a data acquisition module 01 for collecting information of working rolls or support rolls, an execution end 03 for performing adjustment of working rolls or support rolls, and a control end 02 for controlling the action of the execution end 03; the output end of the data acquisition module 01 is connected to the input end of the control end 02, and the control end 02 is connected to the execution end 03.

[0019] In one embodiment, the data acquisition module 01 may include a data reader, which may be a radio frequency card reader, and may interact with an electronic tag carrying information about the strip steel to read information about the working roll or the supporting roll in the electronic tag, and send the read information to the control terminal 02. The data acquisition module 01 may be connected to the control terminal 02 via a CAN bus, or may be connected to the control terminal 02 via a wireless connection.

[0020] In one embodiment, the data acquisition module 01 may also be a measuring instrument, which can detect information such as the diameter of the working roll or the support roll, and send the measurement information to the control terminal 02. Of course, the data acquisition module 01 may also be other common sensor devices on the market, which is not limited here.

[0021] In one embodiment, the device of the embodiment of the present application may further include a storage unit, and the control terminal 02 is connected to the storage unit to store the data uploaded by the data acquisition module 01 in the storage unit, and the storage unit may be a buffer or a random read-only memory, etc. The specific device may be selected and adjusted according to the actual application requirements, and is not limited here.

[0022] In one embodiment, the device of the embodiment of the present application further includes a display module, which can be a liquid crystal display or other touch screen. The display module is connected to the control terminal 02. The control terminal 02 can determine the elevation of the lower roller system based on the data collected by the data acquisition module 01, and then output the elevation of the lower roller to the display module for display. The staff can intuitively judge whether the relevant settings of the current rough rolling are reasonable based on the display content of the display module. The process of the control terminal 02 determining the elevation of the lower roller system is a conventional calculation process. For example, the diameter or thickness information collected by the data acquisition module 01 can be added and the elevation of the lower roller system can be obtained. The control terminal 02 can obtain the corresponding elevation of the lower roller system only through conventional addition and subtraction operations. The control terminal 02 of the present application does not make any improvement to the calculation method of the elevation of the lower roller system. The conventional control devices on the market can be used to realize the functions of the control terminal 02 of the embodiment of the present application. For example, the control terminal 02 can be a microprocessor MCU or a programmable logic gate array.

[0023] In one embodiment, after obtaining the elevation of the lower roller system, the control end 02 can control the execution end 03 to perform a corresponding action. For example, the execution end 03 can be a motor, which adjusts the number of steps of the lower step pads in the rough rolling stage or the finishing rolling stage, thereby controlling the elevation of the lower roller system within a certain range. Of course, the execution end 03 can also be a mechanical arm or a clamping mechanism. It can be set and adjusted according to actual application requirements, and is not limited here.

[0024] Based on the above technical solution of the present application, the diameter of the lower working roll, the diameter of the lower supporting roll, the thickness of the step pad and the thickness of the arc plate can be collected through the data acquisition module 01, and then the controller is used to execute simple addition and subtraction logic to automatically determine the elevation of the lower roll system and output and display the elevation value, so that the staff can intuitively judge the rationality of the setting of the number of lower step pads according to the displayed information; avoid the upper working roll breakage caused by unreasonable setting of the number of lower step pads, which will affect the safety and stability of the operation of the rolling equipment.

[0025] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
