Seamless steel tube one-by-one tracking production system

Abstract

The invention discloses a seamless steel tube one-by-one tracking production system, which comprises a server, a switch, code reading modules and robots, each code reading module, each robot and each production equipment PLC are connected with the switch through the Ethernet, the switch is connected with the server, the server is provided with a plurality of logic stations, the logic stations correspond to production actual physical stations, and the logic stations are connected with the production equipment PLCs through the Ethernet. The server controls the robot to track identifications of pipes one by one in a code pasting and / or code spraying mode in a non-hot-rolling area, receives the identifications read by the code reading module in a hot-rolling area, stores the identifications and logic stations correspondingly, receives signals sent by a production equipment PLC of the hot-rolling area according to physical station switching, and sends the signals to the robot. And logic station switching is correspondingly carried out, so that pipe identification is tracked one by one, and the pipe in a hot rolling area follows the principle of single-line transmission and first-in first-out. According to the method, the yield is improved through information interaction and fusion of multiple length optimization and a one-by-one tracking system, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a branch-by-branch tracking production system for seamless steel pipes. Background technique [0002] The processing technology of seamless steel pipes is complicated, at least involving long billet sawing, ring furnace, piercing machine, rolling mill, sizing machine, cooling bed, pipe row sawing, straightening machine, soot blowing and suction, flaw detector, length measuring and weighing Machines, balers and other related equipment are usually provided by different manufacturers, and each equipment has its own independent PLC control work, and the PLC of each equipment is connected to the production execution system (production execution system), and the production execution system performs the control of each equipment. Process-based control between processes, and real-time access to relevant production information, etc. During the processing of a long billet through vario...

AI Technical Summary

Problems solved by technology

Although the rolling process has a high degree of automation, from the long billet entering the ring furnace to the lower cooling bed, it is a single-line conveyance, but the subsequent production process has many offline processes, the labels are easy to wear, and multiple stations in the production process are frequently on and off the line. It is difficult to track the process branch by branch

[0004] At present, customers have higher and higher requirements on quality, and tracking by batch can no longer meet the requirements of users. Customers require seamless steel pipes to be able to trace production information one by one

Moreover, when there is a problem with the performance of the steel pipe product, it cannot be accurately traced back to which one corresponds to the furnace number, which is not conducive to cause analysis and continuous improvement. The tracking of materials one by one is the basis for realizing the quality traceability of steel pipes and the refined control of production. Traditional production methods It has been unable to meet the requirements of high-end users for the whole process tracking of the production information of a single pipe, and the traceability of the whole process cannot be achieved

Up to now, the following reasons have not been able to realize the whole process tracking of steel pipes one by one:

[0005] (1) The annular furnace is a high-temperature zone, and it is not suitable for marking pipes by conventional methods such as labeling and spraying codes, and there are multiple cut-to-size blanks in the ring-shaped furnace at the same time. Correspondence identification between front and back processes

[0006] (2) No. 1 and No. 2 cooling beds are also high-temperature areas, and the conventional marking method cannot be used to mark the pipes. The cooling bed is a walking beam rack structure. Corresponding identification between

[0008] (4) The pipes are constantly rolling during the production process, the steel pipes rub against each other and the surface stains during the production process make it difficult to identify

[0009] Moreover, since the whole process of steel pipes has not been tracked one by one, it also leads to the process of cutting double-length pipes into fixed-length pipes. Since the relevant parameters cannot correspond to the steel pipes one by one, the cut-to-length pipes also have certain errors.
