description: This work is devoted to the study and development of measures to eliminate surface defects of cold-rolled sheet, as well as to make recommendations on changing the technological parameters of the process. The tasks of the final qualification work: 1. Analyze the types of defects that occur during the production of coldrolled sheet. To identify defects associated with oxidative processes. 2. To analyze the technological process, to identify operations that lead to the formation of a defect of the "yellowness" type. 3. To form and confirm a hypothesis about the causes of the defect formation. 4. Development of recommendations for changing technological parameters in order to eliminate or reduce the likelihood of a defect of the "yellowness" type. The main task of the work is to develop recommendations for changing technological parameters in order to eliminate or reduce the likelihood of a defect of the "yellowness" type. It has been suggested that the "yellowness" defect occurs as a result of the presence of emulsifier residues in the annealing process, which burns. To test this hypothesis, a simulation experiment (CFD analysis) was conducted.
