呋喃树脂自硬砂生产工艺过程控制

Process Control of Furan Resin-Bonded Sand Self-Curing Technology

本文结合生产实际情况，从原材料的准备、混砂、造型、制芯以及再生过程和工艺工装设计等几个方面，简要阐述了如何对呋喃树脂自硬砂生产工艺过程进行质量控制，并且在此基础上制订了工艺操作规程和工艺守则以及原材料验收标准等一系列有关树脂自硬砂的工艺技术性文件，对现场生产起了重要的指导作用。

How to realizeprocess control of Furan resin-bonded sand self-curing technology has been briefly expounded combining practi- cal production with several sections such as raw material preparation, mixing sand, molding, coremaking,recla- mation and technological equipment design which have been depended upon to work out a series of document of techndogy and technique of furan resin-bonded sand self-curing process operational reules, technology regulations and acceptance standard of raw materials to play important role in guiding production on the spot.
