Summary:The production of low-carbon, low-alloy steel coils for oil-industry pipe is considered from a metal-physics perspective. The selection of cooling conditions for the steel sheet and coils after rolling is of particular importance here. Analysis of the accompanying structure formation is based on thermokinetic diagrams plotted by means of data from a deformational dilatometer. To ensure the required mechanical properties and corrosion resistance of Severkor K52 steel sheet, the corresponding structural and phase composition is formed by appropriate laminar cooling of the strip on the roller conveyer at the exit from the broadstrip rolling mill. An industrial experiment permits the production of rolled sheet with the specified mechanical and operational properties on a 2000 rolling mill.
