本文主要介绍采用砂型离心浇铸新工艺铸造收缩管铜铸件的生产经验,包括工艺方案、加工余量、模具设计、造型材料、离心浇铸工艺参数、浇铸要点等。这一新工艺也为扩大离心浇铸方法开创了一条新的途径。它具有适应性强、工装筒单、质量可靠等特点,可供参考。 This paper mainly introduces the production experience of casting shrink tube copper casting by sand centrifugal casting new technology, including process plan, machining allowance, mold design, modeling material, centrifugal casting process parameters, casting points and so on. This new process also opens up a new avenue for expanding centrifugal casting methods. It has adaptability, tooling, single, reliable quality and other characteristics for reference.
