【Abstract】 The static magnetic field for electromagnetic stirrer across mould of 280 mm×380 mm bloom concaster has been measured in situ. It is obtained by analysis on measured results that the current strength shall be selected based on the difference of magnetic intensity of mould inside and outside, to increase the stirring effect and service life of stirring coil.更多还原
