一种新的铸造工艺——磁型铸造法(简称磁型法),已开始应用于铸造生产中。现代铸造车间广泛应用的铸型,是用石英砂和粘土等制成的。而磁型法用粒状铁磁性材料(如铁丸)代替石英砂,用磁场代替粘土,即铁丸在磁场中互相吸引“粘结”,包着气化模,构成铸型(图1)。所谓气化模,是用泡 A new casting process - magnetic casting method (referred to as magnetic method), has begun to be used in casting production. Casting widely used in modern foundries is made of quartz sand and clay. The magnetic method uses granular ferromagnetic material (such as iron pellets) instead of quartz sand, magnetic field instead of clay, that iron pellets attract each other in the magnetic field “bonding”, wrapped with gasification mold, constitute the mold (Figure 1). The so-called gasification mode, is to use bubble
