ANALYSIS AND RESEARCH ON THE LOW STRENGTH OF SPA-H
This article analyzes the reasons for the instability of SPA-H strength by tracking the process,metallographic structure,and non-metallic inclusions.The research analysis of SPA-H shows that the low strength is mainly due to the continuous casting and heat exchange furnace.Improper protective casting results in a higher N content in the slab composition and a decrease in effective Ti content,leading to a lower strength of the steel grade.
