Development of a Manufacturing Technology in 5000 Mill of Rolled Product for Pipeline Projects with Extreme Parameters

Resumo

A system is described for development of new products and technology based on modeling, simulation, and laboratory testing for processes applied to VMZ 5000 rolling mill conditions. Approaches are demonstrated for creating slab heating technology using mathematical modeling of carbonitride particle dissolution and austenite grain growth as well as an approach to creating strategies for rough rolling by new Hot Rolling Recrystallization Model (HRRM) software and the finishing stage. Specific features of rolled product structure formation during cooling and alloying concepts in relation to steel strength class are described. Results are given for industrial production, including steels for underwater pipelines and pipelines in areas near active tectonic faults.
