Utilizing energy-efficient, environmentally friendly, economic production processes and technologies to manufacture high magnetic induction grain-oriented silicon steel has become the focus of current research work. Based on using low-temperature slab reheating techniques to produce high magnetic induction grain-oriented silicon steel at both iron and steel enterprises and research institutions all over the world, the current application and ex- ploitation was thoroughly generalized ; the implementation methods for low-temperature slab reheating techniques by traditional process were also summarized. Furthermore, the recent developments of using thin slab casting and rolling process and twin-roll strip casting process to produce high magnetic induction grain-oriented silicon steel were presented. On these bases, the development trends of production process and technology for high magnetic induction grain-oriented silicon steel were analyzed.
