| titleOfInvention | Magnetostatic field composite rotating magnetic field homogenizes the method and device thereof of large-scale casting ingot solidified structure |
| abstract | It homogenizes the method and apparatus of large-scale casting ingot solidified structure the invention discloses a kind of magnetostatic field composite rotating magnetic field, the eddy flow of the electromagnetic viscosimeter effect and rotating excitation field that are generated by resultant field induces stirring action, to promote forming core, smash dentrite tip, refine crystal grain, even solidification tissue reduces gross segregation, the casting process for large-scale casting ingot.In solidification of metal melt, it is final solidified using the molten metal at ingot mould riser, the easy rate of riser wall and molten metal surface is initially formed nucleus, the characteristics of rotating excitation field and magnetostatic field energy readily penetrate through Riser material, apply magnetostatic field composite rotating magnetic field at insulated feeder, effectively oscillation and stirring are formed to the molten metal in insulated feeder, and oscillation and cyclone mixing are transmitted in the molten metal at ingot mould center by molten metal in riser, smash dentrite tip, refine crystal grain, even solidification tissue, reduce gross segregation, it obtains fine and close, homogeneous, the large-scale casting ingot of crystal grain refinement, promote its properties for follow and military service performance. |
