一、前言世界各国对铸造辅助材料都十分重视。它的品种、质量和生产方式反映了铸造生产技术水平,对提高铸件质量,简化管理和节省能源均有极其重要的作用。我国在这方面起步较晚。目前处于研制和开发阶段,尚未形成专业化、系列化商品生产。我部机车车辆工业系统三十多家工厂,几乎都有铸造车间,但至今大部份辅助材料仍处于自配自用的生产方式,没有完整的质量指标和检验方法,与社会化大生产发展形势不相适应。由 I. Preface The countries all over the world attach great importance to the auxiliary materials for casting. Its variety, quality and mode of production reflect the level of casting production technology, to improve casting quality, simplify management and save energy are extremely important role. My country started late in this regard. Currently in the research and development stage, has not yet formed a professional, serialized product production. Most of our auxiliary materials are still in a self-employed mode of production. There is no complete set of quality indicators and testing methods, which are in line with the development of socialized large-scale production Not suitable. by
