AI Technical Summary
Technical Problem
During the cold rolling process, silicon steel sheets with high Si content are prone to brittle fracture. Existing heating methods involve energy waste and environmental impact, and it is difficult to stably suppress fracture.
Method used
A combination of full-width heating devices and edge heating devices is used to control the temperature of the central part and the ends of the steel plate in the width direction, respectively, to ensure that the end temperature is higher than the central temperature, and then the plate is rolled by a cold rolling mill.
Benefits of technology
It achieves stable suppression of brittle fracture of silicon steel sheets under low environmental load, reduces energy consumption, and improves the stability of the cold rolling process.
