Влияния величины разности вытяжек по ширине полосы при прокатке электротехнической анизотропной стали на образование дефекта геометрии «продольный надав»

Abstract

The paper investigates the reason for the formation of a «longitudinal indentation» geometrical defect. This de-fect occurs at the final stage of electrical anisotropic steel production. A hypothesis about the influence of the difference in the elongation across the strip width on the defect formation is proposed. An experiment to confirm this hypothesis is described. A proportional relationship has been found between the value of the elongation difference across the strip-width and the probability of a «longitudinal indentation» defect.
