Abstract

The invention discloses an electromagnetic sensor of an electromagnetic stirring device of a slab continuous-casting crystallizer and belongs to the electromagnetic stirring device of the slab continuous-casting device with an aim to solve the problem of flux leakage of an iron core. The electromagnetic sensor comprises the iron core, multiple sets of coils and a magnetic shield, the iron core is a columnar iron core composed by stringing and stacking multiple E-shaped iron core bodies together, and each E-shaped iron core is composed of highly-permeable E-shaped silicon steel sheets; the coils identical in the number of windings are respectively wound on the outer side of the columnar iron core, and each coil is conducted with alternating current with a certain phase position, frequency and current intensity; the magnetic shield is an opening shield and is arranged on the rear side of the iron core, and the opening side of the magnetic shield faces a crystallizer copper plate. By the aid of the electromagnetic sensor with the magnetic shield structure, trend of a magnetic line of force in space is changed, higher magnetic sensing intensity can be generated under the condition of the same input current, electromagnetic force can be enhanced, efficiency of the system is improved, and interference of the magnetic field of the stirring device upon peripheral equipment instruments is greatly reduced.

Description

technical field [0001] The invention relates to an electromagnetic stirring device for a slab continuous casting mold, in particular to an electromagnetic inductor structure in the electromagnetic stirring device for a slab continuous casting mold. Background technique [0002] In order to improve the surface quality and internal quality of the slab, in addition to reducing the content of inclusions in the steelmaking and refining process and improving the control level of production process parameters in the continuous casting process, electromagnetic stirring devices can also be used for electromagnetic stirring. That is to say, the surface quality of the slab is not only related to the pouring temperature, casting speed, cooling intensity, argon flow, etc., but also the use of the electromagnetic stirring device is very important, because the electromagnetic stirring device can change the flow rate and flow rate of the molten steel. field range, improve the uniformity of ...
