摘要
介绍夹砂缺陷的特征及其形成机理。防止夹砂缺陷的主要措施是降低型砂的膨胀应力和提高型砂的热湿拉强度。介 绍活化膨润土的简易鉴别方法和膨润土的活化技术。
The features and formation mechanism of the scab defect was introduced. Reducing expansion stress of the moulding sand and increasing wet tensile strength of moulding sand are the main measures to prevent scab defect. A easy method to differentiate activated bentonite and the bentonite activation technique was introduced.
