随着工业的发展,奥氏体铸铁、球铁的应用领域不断扩大。奥氏体铸铁现在及未来的应用范围见表1。美国的奥氏体铸铁产量世界第一,西德占第二位,这种材料无论如何尚未达到饱和的极限。要指出的是,现在的趋势是用柴油代替汽油,据美国估计,燃料费用可节约60％。对大多数阿拉伯产油国家,水的价格与油相当,没有水,石油的精炼是不可能的。为此,大型海水淡化装置的设计要求耐蚀的奥氏体铸铁件,这个有利的市场前景是推动奥氏体铸铁最近5年能迅速发展的重要原因。
With the development of industry, the application of austenitic cast iron and ductile iron has been expanding. The scope of application of austenitic cast iron now and in the future is shown in Table 1. The United States produces the world’s first austenitic cast iron and West Germany takes the second place. The material has not reached the limit of saturation anyway. It should be pointed out that the trend now is to use diesel instead of gasoline. According to the U.S. estimate, fuel costs can be reduced by 60%. For most Arab countries producing oil, the price of water is comparable to that of oil. Without water, oil refining is impossible. For this reason, the design of large desalination plants requires corrosion-resistant austenitic cast iron, a favorable market prospect that is an important reason for the rapid development of austenitic cast iron in the last five years.
