摘要
随着炼油业的发展,炼油厂烟气轮机向着大型化高功率化方向发展,大规格烟气轮机涡轮盘的需求越来越多。宝钢特钢通过新工艺设计,首次试生产出直径为1 250 mm的GH738合金大规格盘件,并对盘件的组织和性能进行了考核,确认各项性能达到进口盘件的实物水平,打破了此类大盘件合金只能依靠国外进口的格局。
With the development of oil refining industry, the flue gas turbine turned to be more larger-scaled and higher powered, also the demand of corresponding large disk was increasing. Baosteel Special Materials Co. firstly manufactured φ 250 mm flue gas turbine disks of GH738 Alloy by means of new smelting technology. Properties of the disk were greatly improved, reaching the level of the imported ones. It changed the situation that this kind of alloy disks could only be imported previously.
