Microstructure and properties of grain oriented electrical steel produced commercially by compact strip processing on production lines

A commercial production line of compact strip processing and a production technology for conventional grain oriented electrical steel were used to manufacture low cost grain oriented electrical steel, whose magnetic properties reached the level of 30Q150. Proper hot band annealing was introduced in order to obtain coarse grain size which promoted the strengthening of Goss texture as well as the increasing of inhibitors' number, so that the magnetic properties could reach the level of 30Q140.
