The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, the utility model comprises shell 2, main coil 1, upper auxiliary magnetic conduction coil 5, lower auxiliary magnetic conduction coil 11, outer auxiliary magnetic conduction coil 10, coolant jacket 9 and radome 3, main coil 1, upper auxiliary magnetic conduction coil 5, lower auxiliary magnetic conduction coil 11, outer auxiliary magnetic conduction coil 10 and coolant jacket 9 all are arranged in the shell 2, coolant jacket 9 be arranged at main coil 1 below, cooling water 8 is housed in the coolant jacket 9; Upper auxiliary magnetic conduction coil 5 is arranged at the top of main coil 1, lower auxiliary magnetic conduction coil 11 is arranged at the below of main coil 1, outer auxiliary magnetic conduction coil 10 is arranged at the outside of main coil 1, the inner of upper auxiliary magnetic conduction coil 5 from bottom to top is 30 ° angle with vertical direction, also can be the angle of other number of degrees beyond in 0 °-45 ° 30 °.
As shown in Figure 2, between main coil 1 and the upper auxiliary magnetic conduction coil 5, between main coil 1 and the lower auxiliary magnetic conduction coil 11, between main coil 1 and the outer auxiliary magnetic conduction coil 10, be provided with insulating barrier 7 between lower auxiliary magnetic conduction coil 11 and the coolant jacket 9; The thickness of insulating barrier 7 is 30mm, also can be other one-tenth-value thickness 1/10 beyond the 30mm in 10-60mm; The thickness of insulating barrier 7 is too little can to affect insulation effect, too greatly then can reduce electromagnetic force, and concrete thickness is decided according to the actual requirements.
The increase of upper auxiliary magnetic conduction coil 5, lower auxiliary magnetic conduction coil 11 and outer auxiliary magnetic conduction coil 10 can significantly improve electromagnetic force, finishes the casting of high desnity metal; The inner of upper auxiliary magnetic conduction coil 5 and the angle of vertical direction then are used for height and the edge arc radius of control liquid metal post 6.
In conjunction with Fig. 2, the process that use the utility model carries out the metal electromagnetic casting is as follows:
1, adjusts level and the relative position of shell 2, main coil 1, upper auxiliary magnetic conduction coil 5, lower auxiliary magnetic conduction coil 11, outer auxiliary magnetic conduction coil 10, coolant jacket 9, radome 3 and bed die (not shown);
2, bed die is risen up into the position corresponding with the utility model, make its end face be positioned at the lower end position place of lower auxiliary magnetic conduction coil 11;
