Background
In the conventional deformed steel bar marking and identifying technology, a method (embedded and external packing) of combining a deformed steel bar surface rolling mark with a finished product packing suspension tag is mostly adopted. The rolling marks are distributed on the surface of the deformed steel bar according to a certain distance proportion and mainly comprise information of manufacturers, rolling lines, specifications and the like; the hanging tag mainly comprises the contents of product rolling product name, execution standard, brand, furnace batch number, time, weight, specification and the like. However, the traditional deformed steel bar marking and identifying technology has certain defects, on one hand, the drop is easy to lose in the hoisting and transporting processes, and the batch of steel cannot be determined after the drop, so that certain difficulty is brought to the tracking and identifying work of the product quality; on the other hand, after the deformed steel bar is cut to a certain length in the using process, the condition that part of the deformed steel bar surface is not provided with rolling marks can be caused, so that the condition of a manufacturer can not be identified in the later period, and the difficulty is brought to the anti-counterfeiting identification, quality tracking and identification of the product. Because these marks are easy to be counterfeited, the production unit of the deformed steel bar used in the engineering project cannot be fundamentally determined, and more importantly, the important data of the production time and the process raw materials cannot be traced.

TABLE 1 database of chemical compositions of deformed steel bar products
The chemical components of the product in the step 1 comprise 20 common chemical elements including C, si, mn, S, P, cr, ni, mo, V, nb, ti, cu, se and Ne.
the step 2 is specifically as follows:
the core technology of the invention is that under the condition of meeting the allowable deviation of the surface shape and the size of the deformed steel bar, the information of manufacturers, rolling lines, rollers and dates is designed in the surface size of the steel bar through the innovative design of the surface size of the steel bar, and an encryption digital sequence which is unique to an enterprise and can not be copied is formed. The surface shape and size indexes of the deformed steel bar comprise an inner diameter, a transverse rib height, a longitudinal rib height, a transverse rib width, a longitudinal rib width, a transverse rib interval, a transverse rib tail end maximum interval, and a transverse rib and axis included angle (the specific shape and size and the allowable deviation of the deformed steel bar surface are detailed in the standard GB/T1499.2-2018 part 2 hot-rolled ribbed steel bar for reinforced concrete steel), in the allowable deviation of the indexes, a plurality of indexes can be randomly selected, the indexes respectively represent different product information according to certain data difference to form unique identification codes of products, and a digital encryption sequence is generated, for example, the transverse rib and axis included angle beta and the transverse rib interval l of the reinforced steel bar are selected as coding indexes, as shown in figure 3;
the national standard requires that the included angle beta between the transverse rib of the deformed steel bar and the axis is not less than 45 degrees, at the moment, the manufacturers are represented by beta, namely, the reinforcing steel bars beta produced by a certain company are unified into 47 degrees, namely, the manufacturers of products are determined by detecting the included angle beta between the transverse rib of the reinforcing steel bars and the axis. In addition, information such as rolling line, rolling roll, production date and the like is represented by the transverse rib pitch so as to
The steel bar with different sizes is taken as an example, the transverse rib spacing of the steel bar with the size is 7.0mm, the allowable deviation is +/-0.5 mm, and the transverse rib spacing with different deviation values (8230; 7.0, 7.0 and lx) can be used at the moment 1 、lx 2 、lx 3 、lx 4 、lx 5 、lx 6 、lx 7 、lx 8 And (d) indicates different product information, of (8230), (8230), of (7, 7), of (8230), of (8230); and of (see fig. 4). Wherein the first two nominal sizes (7.0 mm) represent the start of encryption, the second two nominal sizes (7.0 mm) represent the end of encryption, a period of encryption sequence is represented between the first and second nominal sizes (7.0 mm), and lx is represented in the sequence period 1 Denotes pass line number, lx 2 The number of the rollers is shown, the rollers are generally 'one-by-two-standby', one specification and size are provided with three rollers, and the specific numerical value setting is shown in table 2. lx 3 、lx 4 、lx 5 、lx 6 、lx 7 、lx 8 Indicating the date of manufacture of the product, lx 3 And lx 4 Last two digits, lx, representing year 5 And lx 6 Indicating the number of months, lx 7 And lx 8 Representing a date number. The numbers 0 to 9 are represented by size deviation values, respectively, and the encrypted data corresponding to the different numbers are shown in table 3. E.g. produced in 2021, 9, 12 days
The product of the specification can be coded and marked by the difference of the transverse rib spacing (see table 4), namely the production date of the product is represented by the continuous transverse rib spacing of 7.2-6.7-7.0-7.5-6.7-7.2. When the transverse rib is used as an encryption index, attention needs to be paid to the fact that the value obtained by dividing the distance between the 1 st transverse rib and the 11 th transverse rib in an encryption period by 10 cannot exceed the transverse rib distance allowable deviation required by the national standard. The digital encryption process is carried out on the information of a product manufacturer, a rolling line, a roller, a production date and the like by using the included angle beta between the transverse rib of the deformed steel bar and the axis and the distance l between the transverse ribs as variable indexes. In addition to the above information, the enterprise can edit the password of other different information according to the product characteristics to form the unique identification code of the enterprise. In the process of coding, professional and unique encryption personnel are needed to code a plurality of digits and store the digits as a secret file. This code file is a data system that can compile numerous encrypted digital sequences over time based on product information, as shown in fig. 5.
