What inspection functions are performed for the detection of casting cracks , porosity , and shrinks 如何检验铸件的裂纹,缩孔,缩松?
Non - piping steel 无缩孔钢
Shrinkage / porosity is a common defect in castings and one of main causes making products waste 缩孔缩松是铸件常见的缺陷,是产生废品的主要原因之一。
Tests and production practice have proved that the surface shrinkages have been eliminated and cast quality significantly improved 试验与实际生产结果表明:铸件的表面缩孔彻底消除,铸件质量大大提高。
The finished part shall have a nitride case depth that does not exihibit porosity that extends deeper than the outer half of the nitride case depth 成品件外表面渗氮,只允许在渗氮层的靠外表面的渗层一半深度存在缩孔。
Abstract : introduced is the experience in replacing atmosperic riser with thermal - isolation riser and improving pouring system to eliminate shrinkages 文摘:介绍了用保温冒口代替大气压力冒口,改进浇注系统解决铸件缩孔问题的经验。
Hot runner benefit is delivered at pressure , model can be overcome on certain level the hollow that be not worth as a result of filling makings and forms , shrinkage cavity , be out of shape wait for blemish 热浇口利于压力传递,在一定程度上能克服塑件由于补料不足而形成的凹陷、缩孔、变形等缺陷。
