火力发电在我国能源工业中约占发电总量的80%,汽轮机叶片钢是火电机组的关键材料。我国从50年代初开始生产汽轮机叶片钢。本钢于1950年为北京石景山电厂修复汽轮机提供叶片备件,试炼了第一炉1Cr13钢;1952年试轧了我国早期的静叶和动叶用异型叶片钢。经过四十多年的发展,本钢特殊钢公司已经可以生产20万 Thermal power generation accounts for about 80% of the total power generation in China’s energy industry. Turbine blade steel is the key material for thermal power units. China began production of steam turbine blade steel from the early 1950s. In 1950, Bengang provided blade spare parts for the repairing turbine of Shijingshan Power Station in Beijing, experimenting with the first furnace 1Cr13 steel. In 1952, the special vane steel for static and moving blades in China was trial-rolled. After more than 40 years of development, the special steel company of Benxi Iron and Steel can already produce 200,000
