[0004] The iron and steel manufacturing industry belongs to the traditional stupid and extensive industry. From ironmaking, steelmaking, continuous casting, hot rolling, and then to cold rolling, it is a typical process manufacturing industry. Under the past production mode, each factory has its own The production line has accumulated a large amount of production process data, but these data are independent of each other in each system, basically shelved and rarely used

Embodiment 1
[0068] Take the skin-pass mill section of a cold-rolled hot-dip galvanizing unit as an example, such as figure 1 shown.
[0069] exist figure 1 In section 2 of , 5 represents the seam tracker, 6 represents the tension roller encoder, 7 represents the skin passer, 4 represents the strip, and the strip advancing direction is from left to right. The role of the skin passer is mainly to improve the shape and fine-tune the mechanical properties, and the longitudinal extension of the strip is very small and can be ignored.
[0070] Using the almost scheme of the present invention, assign the real-time process data of the skin passer to the physical position of the strip, and the specific method is as follows:
[0071] 1) Use the weld seam tracker 5 to detect the weld seam (ie, the head of the strip), and send the signal to the tension roller encoder 6 and the skin passer device 7 in real time.
[0072] 2) Calculate the strip stroke. The real-time real speed V of the unit output ...
Embodiment 2
[0082] Taking a hot-dip galvanizing unit as an example, such as figure 1 The process equipment in Section 1 is an annealing furnace, and the process equipment in Section 2 is a tempering machine.
[0083] Section 1 is the previous process of section 2, 1 indicates the weld seam tracker, 2 indicates the tension roller encoder, 3 indicates the annealing furnace, 4 indicates the strip steel, 5 indicates the weld seam tracker of section 2, and 6 indicates the area The encoder and 7 of section 2 represent the tempering machine of section 2, and the direction of strip steel advances from left to right. The main function of the annealing furnace is to adjust the mechanical properties of the strip steel, but due to the high heating temperature, the strip steel will extend longitudinally.
[0084] By adopting the technical scheme of the present invention, the real-time process data of the annealing furnace is assigned to the strip length position, and the specific method is as follows...

Abstract
The invention discloses a method for assigning production process data to the length position of strip steel, and belongs to the field of strip steel cold rolling production processes. A unit is divided into a plurality of sections, and each section comprises a strip steel head and tail detector, a roller encoder and process equipment; the head and the tail of the strip steel are detected by usinga strip steel head-tail detector; the signals are sent to a roller encoder and process equipment in real time; the strip steel travel distance is calculated in real time by utilizing the real-time speed and time integration output by the encoder, the strip steel length between the process equipment and the strip head is calculated in real time by combining the strip steel length among the detector, the encoder and the process equipment, and then process real-time data generated by the process equipment is assigned to the corresponding length position of the strip steel. Real data and strip steel length positions in the strip steel production process are bound in a one-to-one correspondence mode, a large amount of real data information is given to the strip steel length positions, and datacross-unit inheritance and inheritance can be achieved. The method can be widely applied to the field of process control of various strip steel processing and treatment processes.
Description
technical field [0001] The invention belongs to the field of strip steel cold rolling production technology, and in particular relates to a method for assigning production process data to the strip steel length position. Background technique [0002] Digital manufacturing is one of the core technologies of intelligent manufacturing. [0003] On the one hand, in the era of meager profits, higher requirements have been placed on the production efficiency and production cost of iron and steel enterprises; Through digital lean manufacturing, the precise assignment of production process data in the length direction of the strip can be realized. Through the physical location of the strip, the production process data can be connected in series, so that the data scattered in various systems can be linked to develop data and products. Linkage analysis and optimization of quality, energy consumption, cost, etc. are the premise and basis for realizing a data factory; on the other hand...
