Technical Field

[0001] The utility model relates to the application field of steel production, in particular to a finishing rolling double steel tracking information storage device. Background Art

[0002] The existing finishing mill of the hot-rolled coil production line of the steel mill cannot realize double steel tracking and control, that is, the finishing mill cannot roll two strips at the same time. If the tail of the previous strip has not left the final finishing stand (F7 stand), and the next intermediate billet has been bitten in the first finishing stand, the finishing F4-F7 stands will not execute the second preset parameters of the next strip, but still execute the second preset parameters of the previous strip, resulting in the actual strip in the rolling process not matching the second preset parameters of the finishing, and the second flow rate in the finishing stand not matching the steel stacking. Since the existing control system only sets one storage area for the second preset data storage of the finishing, the second preset parameters of the finishing of the two strips are different, resulting in the error of the execution of the parameters set by the on-site equipment, resulting in the scrap steel stacking accident, affecting the smooth production.

[0011] As described above, the utility model provides a device for storing tracking information of fine-rolled double steel, which has the following beneficial effects.

[0012] The present application stores the secondary preset data of finishing rolling in different control stages in different storage modules, and performs read and write operations on different storage modules through a read-write controller to realize accurate time-sharing calling and execution of the set data, so that the secondary preset data of finishing rolling in different control stages are relatively independent and do not affect each other, which can meet the needs of finishing rolling double steel rolling and is conducive to improving the rolling rhythm and production capacity.

[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 1It is a structural schematic diagram of the finishing double steel tracking information storage device in an embodiment of the present application. The finishing double steel tracking information storage device provided in the embodiment of the present application includes a first storage module 01, a second storage module 02, a third storage module 03 and a read-write controller 04, wherein the first storage module 01 is used to store the finishing secondary preset data of the current strip when the current strip arrives at the finishing entrance; the second storage module 02 is used to store the finishing secondary preset data when the finishing first stand bites the steel; the third storage module 03 is used to store the finishing secondary preset data when the finishing first stand throws the steel. The finishing secondary preset data here are all the finishing secondary preset data of the current strip. The finishing secondary preset data can be calculated based on the measured temperature of the intermediate billet at the finishing entrance, and the calculation process is the prior art and will not be repeated here. The first storage module 01, the second storage module 02 and the third storage module 03 are respectively connected to the read-write controller 04, and data reading, writing, erasing and other operations are performed through the read-write controller 04. The read-write controller 04 can read the secondary preset data of finishing rolling in the first storage module 01 to the second storage module 02 when the first stand of finishing rolling bites steel, so that the finishing rolling controller can call the corresponding preset data of finishing rolling from the second storage module 02 for rolling. The read-write controller 04 can transfer the secondary preset data of finishing rolling stored in the second storage module 02 to the third storage module 03 when the first stand of finishing rolling throws steel. The read-write controller 04 can erase the data in the corresponding storage module after completing the data reading each time to release the storage resources, so that the corresponding storage module can receive the secondary preset data of finishing rolling of the next strip of steel.

[0019] In one embodiment, the finishing double steel tracking information storage device also includes a temperature acquisition module, which is arranged at the finishing entrance and connected to the read-write controller 04. When the rough rolling intermediate billet reaches the temperature detection area at the finishing entrance, the temperature of the intermediate billet head is sampled by the temperature acquisition module at the corresponding position, and the sampling result is fed back to the read-write controller 04, and the read-write controller 04 can send the finishing secondary preset data to the first storage module 01 according to the sampling result. Exemplarily, the temperature acquisition module can use temperature sensors such as pyrometers and infrared thermometers. Specific monitoring devices can also be set and adjusted according to actual application requirements, which are not limited here.

[0020] In one embodiment, the fine-rolled double steel tracking information storage device may also include a timer, which is connected to the read-write controller 04. A certain delay is set by the timer, so that the read-write controller 04 reads and writes data based on the delay of the timer.

[0021] In one embodiment, the read / write controller may be one of an MCU, a CPU or a programmable logic gate array. The first storage module 01, the second storage module 02 and the third storage module 03 may all include a random access memory and an electrically erasable programmable read-only memory. The specific types of the read / write controller 04 and the storage module may be set and adjusted according to actual application requirements, and are not limited here.

[0022] Based on the above technical solution of the present application, multiple storage modules are configured, and each storage module is used to store the secondary setting data of finishing rolling in different control stages, so that the finishing rolling equipment can execute the setting data; the structural design of multiple storage modules storing the same data in stages can make the secondary setting data of finishing rolling relatively independent in different finishing rolling stages. Even when two strips are rolled simultaneously during finishing rolling, it can be ensured that there is no cross-interference between the strip rolling and the stored data, which is conducive to improving the rolling rhythm and production capacity.

[0023] 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. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
