Transverse thickness difference is an important quality index of non-oriented silicon steel strips.In order to fulfill users’ accuracy requirements on the transverse thickness of silicon steel and improve the production yield,the factors influencing transverse thickness difference were analyzed.Then the work roll shape,control strategy and incoming hot-rolled strips were optimized.Since the optimization measures were implemented in the actual production,the thickness difference of non-oriented silicon steel has been reduced greatly and fulfilled the requirements placed by users.These measures have achieved remarkable effects.
