采用气化模的铸造法的发展产生了一种新的铸件制造方法,即用松散的铁磁性材料作为造型材料,它们在浇注过程和铸件结晶时受磁场作用而凝聚起来。这种方法就是磁型造型法。将上述造型材料充填入泡沫聚苯乙烯模型后,使产生一个磁场,这种铁磁性材料的颗粒就互相凝聚成为一整体。然后按 The development of casting methods using gasification molds has resulted in a new method of manufacturing castings using loose ferromagnetic materials as modeling materials that condense by the action of a magnetic field during the casting process and the casting crystallization. This method is magnetic modeling. After filling the above styrofoam material into the Styrofoam model, a magnetic field is generated, and the particles of the ferromagnetic material are aggregated with each other to form a unitary body. then press
