冷铁在铸造生产中的应用较广。在铸件上应用冷铁,能够防止缩孔、缩松和裂纹,保证得到组织细密而健全的铸件。一般说来,冷铁在钢铸件上用得比较普遍,但在铁铸件上并不广泛运用。在苏联专家库兹涅佐夫的直接帮助下,我厂在重要的铁铸件(水压试验高,表面满加工的)上,广泛的应用冷铁,消除了高压水压试验时发生渗漏的现象,大大提高了铸件质量。 Cold iron in the casting of a wide range of applications. The application of cold iron in the castings, to prevent shrinkage, shrinkage and cracks, to ensure that the organization of fine and sound castings. In general, the use of chilled iron in steel castings is more common, but not widely used in iron castings. With the direct help of the Soviet expert Kuznetsov, our factory extensively applied chilled iron to important iron castings (high hydrostatic test and full surface finish) to eliminate leakage during high pressure hydrostatic testing Phenomenon, greatly improving the quality of castings.
