摘要
2Cr11MoVNbN钢是目前12%Cr系耐热性能最好的钢种之一,是一种较为理想的亚临界、超临界汽轮机叶片用材料。通过采用VOD炼钢,上平砧,下V型砧拔长下料,多火次,小压下量镦粗工艺,成功锻出2Cr11MoVNbN叶片,质量达到要求。
2Cr11MoVNbN steel is one of the steel grades with best heat-resistant property among 12% Cr steels, and it is an ideal material used for suberitical and supercritical steam turbine blades. Through smelting with VOD method, drawing with top flat anvil and bottom V type anvil, and upsetting with more than one heat and small percent reduction, the 2Cr11MoVNbN steel blades has been produced successfully to meet technical requirements.
