description: In the work "investigation of the causes of the formation of defects of the "yellowness" type on the surface of a cold-rolled sheet. Development of measures to eliminate them" the analysis of the technological process of production of coldrolled steel sheet in the conditions of NLMK PJSC was carried out, assumptions of the causes of defects of the "color shades (yellowness)" type were given. The analysis of foreign and Russian literary sources describing defects, the formation of which is caused by the oxidation process, is carried out. The causes of the formation of oxidation defects and ways to eliminate defects are considered. It has been suggested that a defect of the "yellowness" type is a combination of defects such as "staining" and "spotty carburization". A chemical analysis of process fluids, namely emulsifier and training fluid, was also carried out. Based on the data obtained, a simulation of the annealing process in a muffle furnace was carried out to confirm the hypothesis of the occurrence of a defect of the "yellowness" type. Based on all the studies conducted, recommendations were put forward to eliminate the identified defect.
