| 不锈钢精密铸造可以追溯到上世纪三四十年代，美国最早用不锈钢精密铸造法对其当时科技领先的航空发动机中的涡轮叶片进行铸造，成品受到了各方面的好评，进而使这种方法得到推广。 Stainless steel precision casting can be traced back to the 1930s and 1940s of last century. The United States first used stainless steel precision casting method to cast the turbine blades in its leading aero-engine at that time. The finished products were highly praised by all aspects, which promoted this method. 我国对不锈钢精密铸造的研发和使用则是在新中国成立之后，随着我国国防工业的发展，辽宁、贵州、北京、陕西、湖南等地都开设了不锈钢精密铸造研究所或铸造厂。不过，客观地说，我国不锈钢精密铸造行业仍然在发展阶段，尚不能满足我国航空航天、国防工业等行业的发展需求。 The R & D and application of stainless steel precision casting in China was after the founding of new China. With the development of China's national defense industry, stainless steel precision casting research institutes or foundries have been opened in Liaoning, Guizhou, Beijing, Shaanxi, Hunan and other places. However, objectively speaking, China's stainless steel precision casting industry is still in the development stage and can not meet the development needs of China's aerospace, national defense industry and other industries. |
