一、前言不锈钢铸件在原子能、海洋开发以及石油化工等工业部门已广泛使用.由于使用环境日趋苛刻,因此势必要求研制出综合性能良好的超高强度、超纯度的不锈钢铸钢材料.日、美、苏、西德等国均作出巨大努力,取得了可喜的进展.同时,在冶炼技术、冶炼工艺、造型材料、铸造工艺设计等方面均有所突破.我国与之相比有一定差距,这就需要全国铸造界同行同心协力,为之奋斗.
I. INTRODUCTION Stainless steel castings have been widely used in industrial sectors such as atomic energy, marine development and petrochemical industry.As the increasingly harsh environment, it is bound to require the development of ultra-high-strength, ultra-pure stainless steel castings with good overall performance. , The Soviet Union, the West Germany and other countries have made tremendous efforts and made gratifying progress.At the same time, the smelting technology, smelting process, modeling materials, casting process design and so on have made a breakthrough.China compared with a certain gap, which You need the national counterparts foundry sector work together to fight.
