黑色金属铁模铸造如果运用得当与砂型铸造比较具有下列优点。如:改善劳动条件;提高铸件的密度和强度;获得优良的表面光洁度;有利于大量生产铸件的尺寸控制,省去砂处理系统;提高金属收得率;减少占用的车间面积等。但是铁模铸造未能在铸造业中获得普遍采用的主要原因是所生产的每吨铸件铁模费用高,即铁模的使用寿命短和制造费用高。特别是采用水冷缩短铁模周期后,虽然提高了生产率,但是加剧了铁模寿命的缩短。因为它导致对铁模的强烈热冲击,只有在少数场合铁模寿命能超过15000～20000次,有时操作者仅仅浇了300～800次,铁模就不能再用了。最近铁模铸造机的新发展是由一系列在两条轨道上运转的简单铁模输送小车组成。一条
Black metal iron mold casting, if used properly, has the following advantages over sand casting. Such as: to improve working conditions; to improve the density and strength of castings; access to excellent surface finish; is conducive to the mass production of casting size control, eliminating the sand processing system; improve the metal yield; reduce the occupied workshop area. However, the main reason that iron mold casting is not universally adopted in the foundry industry is the high cost per ton of cast iron that is produced, the short service life of the iron mold and the high manufacturing costs. In particular, the use of water-cooled iron mold cycle shortened, although increased productivity, but exacerbated the iron mold life shortened. Because it leads to a strong thermal shock on the iron mold, only in a few occasions iron mold life can exceed 15000 ~ 20000 times, and sometimes the operator poured only 300 ~ 800 times, iron mold can not be used again. Recent developments in iron mold casting machines consist of a series of simple iron mold transfer carts operating on two tracks. One
