Application and technology of foundry method in permanent mould with sand facing 铁型覆砂铸造工艺及其应用
Casting solidification simulation of sand faced permanent iron molding technology and its application 铁型覆砂铸造工艺凝固模拟及应用
The sand faced - iron mould casting process is a special iron castings production process , according which castings are to he cast in the iron moulds having a thin layer of the resin sand facing in their inner surfaces 摘要铁型覆砂铸造是指在金属型(铁型)内腔覆上一薄层树脂砂,然后采用这种覆砂铁型浇注铸件。
Since the sand faced - iron mould has high rigidity , it is possible , when used for crankshafts production , to adopt feeder - less foundry method and increase the process yield , as well as increase dimension accuracy of castings and improve surface quality of castings 由于覆砂铁型刚度较高,用于球铁件能实现无冒口铸造,提高工艺出品率,并能提高铸件尺寸精度,改善表面质量。
In this paper the technolqical principle , furnish and application status of permanent mould with sand facing was introduced . application shows that the technology was suitable for mass production of high quality casting , suchas crankshaft , valve and cylinder sleeve 介绍了铁型覆砂铸造的工艺原理、工装及生产应用情况,应用表明:该工艺适用于曲轴、阀体、缸套等大批量、高质量的铸件生产。
