随着石油、化工、造纸、化纤工业的发展,合金钢所占的比例不断增加,例如:近十年来苏联生产的合金钢铸件增加了90%,英国、美国、日本各国也逐年增长。因高合金钢中通常含镍量较高,故随着高合金钢铸件生产的不断增长,镍的消耗量也与日俱增,引起国际市场上镍的价格不断上涨,这对缺镍资源的苏联、东欧以及其他国家带来一定威胁,故近年来这些国家十分重视节镍、代镍的研究与应用。本文介绍几种国外已在生产上应用的节镍、代镍铸钢的性能。
With the development of petroleum, chemical industry, papermaking and chemical fiber industry, the proportion of alloy steels has been continuously increasing. For example, the output of alloy steel castings produced by the Soviet Union has increased by 90% in recent ten years, and the United Kingdom, the United States and Japan have also increased year by year. Due to the high nickel content in high-alloy steels, the nickel consumption is also increasing with the increasing production of high-alloy steel castings, causing the price of nickel on the international market to rise continuously. This is especially true for the Soviet Union, Eastern Europe As well as other countries to bring a certain threat, in recent years, these countries attach great importance to nickel and nickel research and application. This article describes several foreign countries have been applied in the production of nickel section, the performance of nickel cast steel.
