离心铸造是一种先进的生产方式,它具有一系列的优点,如简化工序、提高效率,缩小生产面积、减少金属和造型材料消耗、分离非金属和杂质、消除缩孔和气孔等.因而能提高铸件密度,降低废品率.此外还能减少浇冒口,增加成品率和产量,加速生产和节约金属,尤其在成批和大量生产时更为明显.例如我厂掌握了离心铸造后,套类废品率便从50%左右下降到3~6%.我厂在1953年增添了数台离心机.在设计和使用过程中曾遇到一些问题,严重时废品率达100%,几乎停产,经过一年多的努力才较为好转,现将生产中的点滴经验介绍如下.
Centrifugal casting is an advanced method of production, which has a series of advantages, such as simplifying the process, increasing efficiency, reducing production area, reducing the consumption of metal and molding materials, separation of non-metallic and impurities, to eliminate shrinkage and porosity, etc. Thus Improve the density of castings and reduce the rejection rate.In addition, it can reduce the pouring riser, increase the yield and output, speed up the production and save the metal, especially in mass and mass production more obvious.For example, I have mastered the centrifuge casting, the sleeve The rate of scrap was reduced from about 50% to 3 ~ 6% .Our factory added several centrifuges in 1953. In the process of designing and using, we encountered some problems, the rate of rejects was 100% in severe cases, almost stopped production, After more than a year of hard work is more improvement, now the production of bit by bit experience described below.
