Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.

A visual material tracking method for identifying flaw detection plates and representative plates on line comprises the steps of S1-S3.

S1, determining the steel billet of the representative plate and the steel billet of the flaw detection plate.

Before the steel billet is formed, a plurality of steel billets are selected as steel billets of the representative plate according to a company production plan, and a plurality of steel billets are selected as steel billets of the flaw detection plate according to customer requirements.

And S2, classifying the representative plate and the flaw detection plate.

After the billet is formed, each billet follows the roller table and the billet passes through a heating furnace and a rolling mill in sequence to form a steel plate.

The steel plate formed by the steel billet continues to run along with the roller way after passing through the rolling mill, and when each steel plate runs to the jet printing machine on one side of the roller way in sequence, the jet printing machine sprays a first plate number on each representative plate, wherein each first plate number comprises a plurality of characters which are arranged in sequence; all the first board numbers are different from each other, and the terminal characters of all the first board numbers are the same.

Spraying a second plate number on each flaw detection plate by the spray printing machine, wherein the second plate number comprises a plurality of characters which are sequentially arranged; all the second board numbers are different from each other, and the terminal characters of all the second board numbers are the same; the end character of the second plate number is different from the end character of the first plate number.

For steel plates which need to be used as a representative plate and a flaw detection plate at the same time, spraying a third plate number on the steel plates by a spray printing machine, wherein the third plate number comprises a plurality of characters which are arranged in sequence; all the third plate numbers are different from each other, and the terminal characters of all the third plate numbers are the same; the terminal character of the third plate number is different from both the terminal character of the first plate number and the terminal character of the second plate number.

In this embodiment, the end number (terminal character) of the flaw detection plate is denoted by S, the end number representing the plate is denoted by T, and the end number of the steel plate is denoted by Z for a steel plate which requires both flaw detection and sampling. If a steel plate needs to be sampled, the original plate number is E1518006000, which is now changed to E151800600T.

In addition, before the billets enter the heating furnace, the sequence of the billets entering the heating furnace is checked by a worker, the control unit assembly sends the plate number corresponding to each billet to the jet printing control unit, and the jet printing control unit sends the plate number corresponding to each billet to the jet printing machine; wherein, the control unit assembly is located the control chamber, spouts seal the control unit and is located one side of roll table. Before the steel billets enter the heating furnace, the plate numbers corresponding to the steel billets are sequentially input into a control unit assembly (a secondary control system) according to the sequence of the steel billets entering the heating furnace.

And a display screen on the flaw detection station displays the analog signal of the steel plate near the station. Therefore, the position of the flaw detection plate or the representative plate is judged by workers in the operating room according to the analog signals on the main display screen, and when the flaw detection plate or the representative plate is about to reach the corresponding station, the workers in the operating room start sampling head cutting scissors or flaw detection equipment through the control unit assembly. Similarly, after the steel plate passes through the rolling mill, the jet printing control unit is communicated with the jet printing machine, and the jet printing machine carries out plate number spraying on the representative plate or the flaw detection plate according to the received plate number information. Particularly, when needing the sample, start the sample crop and cut the head and cut, the staff in the control chamber moves corresponding operating personnel to go the sample station simultaneously and assists the sample. Therefore, operators do not need to be arranged on the sampling station at any time.
