The present invention smeltings key technology operation principle with have the beneficial effect that:
The present invention technology in, permanent magnetism partition part filling smelting furnace and permanent magnetic stirring magnet between space, provide one
Non-uniform magnetic-field and temporal pulsed magnetic field spatially, pass through this non-uniform magnetic-field spatially and temporal pulse
Magnetic field causes to be formed the effect of surge, for spatially, specifically by a non-uniform driving force inside metal liquid
Process is such, by permanent magnetism partition board in for fan-shaped, it is assumed that when original state the South Pole of permanent magnetism partition board downward, arctic court
On, the South Pole rotation of permanent magnetic stirring magnet at this time comes, since the magnetic field intensity of permanent magnetic stirring magnet is more than the magnetic of permanent magnetism partition board
Field intensity, permanent magnetism partition board are magnetized, and become the arctic downward, the South Pole upward, due to obtaining the reinforcement in permanent magnetism partition board magnetic field, permanent magnetism
Metal liquid right over partition board is under the field drives of a bigger, and the metal fluid rotated at this time is in the position of permanent magnetism partition board
It puts(The South Pole of permanent magnetic stirring magnet is located just at the underface of permanent magnetism partition board at this time), relative to the arctic of permanent magnetic stirring magnet
Position, by the field drives of bigger, this uneven driving may result in the deformation and compression of metal fluid, in metal fluid
Surface, which is formed, significantly surges, in addition, for from the time, during in the South Pole of permanent magnetic stirring magnet, rotation comes, forever
The original polarity of magnetic partition board be the South Pole downward, the arctic upward and the polarity in the South Pole of permanent magnetic stirring magnet that comes of rotation on the contrary,
Before the South Pole for the permanent magnetic stirring magnet being rotated magnetizes, the magnetic field that the metal liquid above permanent magnetism partition board is experienced is small
In the magnetic field intensity of the South Pole of permanent magnetic stirring magnet in itself, after magnetization, the metal liquid above permanent magnetism partition board can be experienced
Magnetic field moment increase, that is, pulsed magnetic field, the appearance of pulsed magnetic field so that metal liquid above permanent magnetism partition board by
Moment increased driving leads to the deformation and compression of metal fluid, is formed on metal fluid surface and significantly surged.When permanent magnetism stirs
Mix magnet the South Pole be rotated away from after, the polarity of permanent magnetism partition board be the arctic downward, the South Pole upward, when the north of permanent magnetic stirring magnet
During pole rotation comes, and above-mentioned process can be repeated, generation non-uniform magnetic-field spatially generates arteries and veins in time
Rush magnetic field.Permanent magnetism partition board it is in uneven thickness, the thickness of permanent magnetism separator edge is less than the thickness among permanent magnetism partition board, this be in order to
The impact of the driving device discontinuity of permanent magnetic stirring magnet is reduced, since the magnetic pole and permanent magnetic stirring magnet of permanent magnetism partition board lean on
Magnetic pole near procedure is on the contrary, permanent magnetic stirring magnet by a repulsive force, can cause the driving current of driving device to occur one
A steep increasing can increase the load of transmission system, driving circuit and control system moment in this way, and when the magnetic polarity reversal of permanent magnetism partition board
And when consistent with the magnetic pole of permanent magnetic stirring magnet, repulsive force pop-off that permanent magnetic stirring magnet is subject in this way can wink
Between reduce the load of transmission system, driving circuit and control system, increase the variation dropped suddenly suddenly to being driven to reduce this moment
