Qualities of Pseudo-rimmed Steel Sheet Manufactured by Strand Casting

Abstract

New pseudo-rimmed steel has been developed in order to improve the performance of conventional low carbon Al-killed and Si-killed steels.
This paper describes the operability, formability, surface treatability, surface properties, welding properties, etc., of hot strip, cold strip and surface-treated sheet.
The performance of pseudo-rimmed steel is found almost satisfactory. The deoxidation of molten steel with a minimum amount of Al without using Si has a significant effect on the improvement of the product performance.
