摘　　要：铸件缩松缺陷是铸造行业内公认的难题,冷铁是解决铸件缩松、缩孔缺陷的首选途径。结合实际生产现场经验,从冷铁的材料选择、冷铁形式、布置形式及冷铁固定等方面进行了归纳和探讨,提出了不同铸件材料、不同铸件结构适用的冷铁选取依据,最后指出:选择合适的冷铁材料,根据铸件结构设计方便使用的冷铁形状和激冷效果较好的冷铁尺寸,选择合理的冷铁布置形式,能够实现对铸件热节位置的激冷,从而消除铸件缩松缺陷。Shrinkage defect was the widely recognized difficult problem of foundry industry,using chills were the preferred way to eliminate the shrinkage defects.Combined with the practical production site experience,summarized and discussed the selection of chill material,chill form,layout form and fixation method,proposed chills selecting basis for castings of different materials and different structures.Finally pointed out:selecting proper chill material,designing easy used chill shape and chill dimensions could reach good chilling effect,realize chilling to the hot spots locations of castings,and thereby eliminate shrinkage defect of casting.
