The Development and Application of Steel Sheet for Glass-Lining at Baosteel

摘要

Traditional hot-rolled steel plate is prone to serious fishscale after enameling to manufacture glass-lined equipment and accessories. A new series of hot-rolled steel plates for one-sided and two-sided glass-lining were developed successfully at Baosteel. This paper investigates the effect of the chemical composition and alloying element titanium (Ti) as well as the microstmcture and properties of the steel plates. The results show that the series of steel plates with the Ti addition showed excellent fishscale resistance, weldability, and higher yield strength after high-temperature firing to satisfy the requirements for glass-lined equipment and accessories.
