Abstract: The influence of normalization process with a bell furnace on the structure, inclusions and properties of 50W350 electrical steel hotrolled sheet was studied. The research results showed that: when the steel was normalized at a certain temperature in the bell furnace, the silicon steel grains gradually recrystallized and grew up with the extension of the annealing holding time，and at the same time, the precipitates also gathered and grew up. The recrystallization and growth of the silicon steel grains were realized by formulating a reasonable normalization process in a bell furnace so as to meet the technical requirements of the product normalized in a continuous annealing furnace.

Key words: electrical steel, normalization process in a bell furnace, grain size, hot rolling
