IMPROVEMENT OF PRODUCTION TECHNOLOGY FOR GRADE OF STEEL 80P IN THE CONDITIONS OF PJSC "MAGNITOGORSK IRON AND STEEL COMPANY"
This article discusses the existing technology for the production of steel grade 80P. The list of shortcomings of the current technology that negatively affects the quality of steel billets is given. In order to reduce non-metallic inclusions in steel, the high content of which increases the breakage of rolled products, it is recommended to reduce the content of silicon and aluminum in the steel. To increase the deformability of rolled products during drawing, it was proposed to introduce a two-stage cooling technology on the Stelmore line.
