Abstract：To ensure stable control of yield strength in HRB400E-1 steel,optimization of nitrogen control parameters and regulatory mechanisms is essential.This study investigates the influence of key process stages on nitrogen content,analyzes the response patterns of yield strength under nitrogen fluctuations,and explores an optimized nitrogen control model based on spectral feedback and total nitrogen input constraints.The findings provide technical support for intelligent refining control and performance stabilization in high-strength steel production.
