灰铁铸件

铸件加工面一旦产生疏松、缩松则成为废品。疏松首先可能是由于结构不合理而引起的。疏松、缩松与缩孔一样产生在壁厚较大的部位上，甚至产生在凹角部位,因为该处是通过相应铸型凸台部份或泥芯进行散热,故该处散热差,金属凝固比较缓慢。对具有30或60“或90，张角的Y型试块的对比试验表明、凹角处外缩孔,随张角增大而减小与此同时缩孔减少,而使疏松增加。设计出工艺上合理的结构是获得致密铸件的重要条件之一。但对一个铸件;结构设计员设计时首先考虑的是使用要求;其次才是工艺上的合理性。

Once the casting surface is loosened and loosened, it becomes a waste product. Looseness may first be caused by an unreasonable structure. Looseness, shrinkage and shrinkage are produced in the part with a large wall thickness, even in the concave corner, because the heat is dissipated through the corresponding casting boss or core, so the heat is poor, metal solidification It is slow. A comparative test of a Y-shaped test piece having a 30 or 60" or 90-angle angle indicates that the shrinkage hole at the concave corner decreases as the opening angle increases, and at the same time, the shrinkage hole decreases, and the looseness increases. A reasonable structure is one of the important conditions for obtaining a dense casting. However, for a casting; the structural designer first considers the use requirements; the second is the process rationality.
