甲:听说有一种新型工程结构材料叫蠕虫状石墨铸铁,开始在国内外应用,您能否给我介绍一下?乙:可以。蠕虫状石墨铸铁在今天有点像五十年代的球墨铸铁,发展十分迅速,各国铸造界对它甚为重视。在1977年第四十四届国际铸造会议上成立了蠕虫状石墨铸铁委员会,由美国Loper教授任主席,负责发展、研究及推广这种铸铁的工作。当前,我国各有关研究机关、高等学校及工厂正对这种铸铁进行研究和生产。

A: I heard that there is a new type of structural engineering materials called worm-like graphite cast iron, began to be applied at home and abroad, can you tell me about it? B: Yes. The worm-like graphite cast iron is a bit like the nodular cast iron of the 1950s. The development is very rapid. Casting circles in various countries attach great importance to it. At the Forty-fourth International Foundry Conference in 1977, a worm-shaped graphite iron committee was established and chaired by Professor Loper of the United States to develop, research and promote such cast iron. At present, all relevant research institutions, universities and factories in China are studying and producing such cast iron.
