摘　　要：本文介绍高强度球墨铸铁用于制造薄壁铸件时,既保证高强度又防止白口的途径,并着重就变质剂的消耗、碳当量及壁厚对铸铁的白口倾向、金属基体变化及机械性能的影响机理进行了论述。In application of high-strength spherulitic cast iron to thin-walled casting,the way to guarantee both high strength and chill-proof is described。The mechanism and factors such as quantity of modificator consumed,C-equivalent and wall thickness and their effect on the hilling tendency.change in the metal matix and in its mechanical performance are discussed.
