前言自从D.Sclielleng取得紧密/蠕虫状石墨铸铁(以下简称紧密石墨铸铁,译者注)生产工艺的第一个专利以来,15年已经过去了。在这15年中,这种铸铁在性能测定以及生产工艺和工业应用等方面都取得了重大的进展。但是有两个因素多少妨碍了这种材料在工业方面的迅速扩大应用。第一、这种材料突出的优点尚未得到铸铁件设计者和生产者的应有的评价,第二、生产厂家还未完全掌握住相应的生产工艺,因而他们还持有某种保留态度。
Foreword Fifteen years have passed since D.Sclielleng acquired the first patent in the production of compacted / vermilion graphite cast iron (hereinafter referred to as “compact graphite cast iron”). During these 15 years, this cast iron has made significant progress in the determination of properties as well as in production processes and industrial applications. However, at least two factors have hampered the rapid industrial expansion of this material. First, the outstanding advantages of this material have not been properly evaluated by the designers and producers of cast iron. Second, the manufacturers have not yet fully mastered the corresponding manufacturing processes, and therefore they also hold some reservations.
