Bar finishing process data synchronization method

Abstract

The invention discloses a bar finishing process data synchronization method, and belongs to the technical field of steel rolling automatic control. According to the invention, the method comprises thesteps: enabling sampling data generated in all procedures in the bar finishing process to be corresponding to the length direction of a bar and to be displayed under the same percentage of the lengthof the bar, wherein when the process sampling data volume is small, an interpolation method is adopted to fill the sampling data; under the condition that the sampling data volume is large, deletingthe sampling data by adopting an averaging method to achieve the purpose of the same sampling data volume, and finally realizing synchronous display of the sampling data of each process. Actual measurement data of all procedures at any length position can be inquired according to the synchronized data, a convenient and rapid product quality data inquiry mode is provided for workers on site, and subsequent quality defect positioning and tracing are facilitated.

technical field [0001] The invention relates to the technical field of steel rolling automatic control, in particular to a bar finishing process data synchronization method. Background technique [0002] The bar finishing process is a key process in the quality control of special steel products, which can effectively improve the grade, reduce product defects, and increase the added value of products. Through the processes of shot blasting, straightening, chamfering, flaw detection and grinding of the bar, the surface and internal defects of the bar are eliminated, the flatness is improved, and the purpose of meeting the standards and user needs is achieved.

Problems solved by technology

[0003] There are many processes in the bar finishing process, each process has corresponding process parameters and quality indicators, and the speed of bars passing through each process is different, and the process parameters and quality indicators of each process are stored according to a fixed sampling cycle , resulting in different times for bars to pass through different processes, making the number of sampling points in each process inconsistent

However, the sampling points are displayed and output according to the time in WINCC and other clients. As a result, the physical positions of the bars corresponding to the sampling points in each process are different, and the sampling points are not synchronized with the physical positions. It is difficult for craftsmen to intuitively and accurately find out the actual location of defects through the sampling point curve, which makes it difficult to trace product quality defects

[0004] In the document "Establishment and Application of Synchronous Data in the Production Process of Continuous Cold Rolling", a method for establishing synchronous data in the rolling section of the tandem cold rolling mill is proposed. The measured rolling parameters collected in real time are mapped to the finished coils. In terms of length, the cold rolling mill section is only a single process in the production process. According to the constant flow rate, the speed conversion can be conveniently performed to realize the corresponding data; at the same time, the finishing and chamfering process only eliminates defects at specific positions at the end of the bar. Significantly different from the tandem cold rolling mill, the data correspondence mentioned in the literature is no longer applicable to the bar finishing process
