一、前言工业铸铁的基体和工业纯铁及钢一样,且由于碳和杂质含量较高,并存在不同形态的石墨夹质物故脆性高、塑性差。若能对其碳含量、温度及加工速率等加以限制,创造良好的内在与外在加工条件,并非绝不能进行压力加工。第二次世界大战期间,德国人曾将灰口铸铁用压力加工的办法制得薄板和细棒。最近谷口希限制白口铁的碳含量并在较高的温度进行热加工也获得了令人满意的结果。制品中细化的莱氏
I. INTRODUCTION The substrate of industrial cast iron is the same as that of industrial pure iron and steel. Due to the high content of carbon and impurities and the different shapes of graphene, it has high brittleness and poor ductility. If the carbon content, temperature and processing rate can be limited, to create a good internal and external processing conditions, not without pressure processing. During the Second World War, Germans used gray cast iron to make sheets and thin rods by pressing. Taniguchi recently limited the carbon content of white iron and heat processing at higher temperatures have also been satisfactory results. Lai’s refined products
