传统的铸造行业深受粉尘、振动、异臭、噪声等问题的困扰,属脏、险、累的3K作业。本文介绍日本前川制作所开发成功的冻结铸型(砂型)铸造法。该铸造法是在制作砂型的工序中,使用水(利于环保)作粘结剂,通过冻结其里面的水制成砂型的施工方法。文中介绍了该铸造法的特点、特性和施工工序。评估了环境、成本等因素,还例举了应用实例。
The traditional casting industry by dust, vibration, smelly, noise and other problems plagued by dirty, dangerous, tired 3K operations. This article describes the successful development of Japan’s former Sichuan Institute of Casting (sand) casting method. This casting method is a method of constructing a sand mold by freezing water in the sand making process using water (environmentally friendly) as a binder. The paper introduces the characteristics of the casting method, features and construction processes. Assess the environment, costs and other factors, but also illustrates the application examples.
