摘　　要：采用普通呋喃树脂砂生产铸件时,铸件的某些特殊结构部位由于吃砂量小,或长期受到铁液冲刷或浸润,易形成严重的粘砂缺陷。本文根据实际生产经验,介绍铸铁件特殊位置的几种防粘砂工艺方法。By ordinary resin sand production casting, the casting of certain special structural position due to the small amount of sand, or long by hot metal erosion or infiltration, easy to form a serious sticky sand defect. According to the practical production experience, the paper introduces several kinds of anti - bonded sand process method for the special position of cast iron.
