Description

technical field [0001] The invention mainly belongs to the technical field of electromagnetic torque measurement of an electromagnetic stirrer for a crystallizer, and in particular relates to a measuring method and device for measuring the electromagnetic torque of an electromagnetic stirrer for a continuous casting mold. Background technique [0002] On the one hand, electromagnetic stirring acts on the molten steel in the center of the billet through an alternating magnetic field, and the electromagnetic thrust generated stirs the molten steel, thereby breaking the columnar crystals at the solidification front, and the unfused part of the broken crystals serves as the crystal nucleus of the equiaxed crystals; on the other hand, it is The composition and temperature of molten steel are made uniform by stirring, and the temperature gradient of the solidification front is reduced. The use of mold electromagnetic stirring technology in continuous casting can not only improve t...
