description: The object of the study is an etched sub-roll, in particular the contamina-tion of the metal strip with chlorides after etching in baths with hydrochloric acid. The aim of the work is to develop a technology that allows controlling the presence of chlorides on the pickled strip using machine vision and making decisions on the quality of metal strip washing depending on the result of control. Scientific approaches used to solve the problems of the project: 1) studying the theoretical part; 2) application of the theoretical part to set up experiments; 3) scientific investigation of the results of experiments and modeling. During the scientific research, the following activities were carried out: 1) development of a methodology for monitoring the presence of chlorides on etched metal strips; 2) preparation of necessary samples for research; 3) testing of methods with different initial parameters; 4) development of the hardware part of the experimental sample of the chloride detection system on etched metal strips; 5) development of the software part for the experimental sample of the chloride detection system on etched metal strips; 6) conducting necessary experiments. As a result of the research, the following results were obtained: 1) a promising method for controlling the presence of chlorides on metal was identified for implementation in the production line; 2) an economical and effective qualitative reagent for chloride ions was selected; 3) necessary metal samples were prepared for research; 4) an experimental sample of the chloride detection system on etched metal strips was assembled; 5) the software part for the experimental sample was developed: a) a flexible program was developed for controlling the presence of chlorides on etched metal strips; b) an interface was developed for convenient control of the monitoring process and flexible adjustment of input parameters. 6) necessary experiments were conducted to confirm the operability of the proposed solution. The results obtained during the qualification work will help reduce the probability of metal corrosion in the warehouse of etched rolls, which will improve the quality of the product and the consumer experience. And reducing the number of defective cold-rolled steel rolls will reduce the carbon footprint of the manufacturer, which corresponds to the new state development strategy for achieving zero carbon emissions.
