摘　　要：通过大型高温合金钢锭电渣重熔工艺的研究，成功试制出了国内最大高温合金钢锭——GH2674合金φ900mm的钢锭；开发了新的涡轮盘分区变形的锻造工艺，利用4000t快锻机成功试制出了φ1840-φ2118mm的超大型高温合金涡轮盘。采用分区锻造新工艺生产的超大型GH2674舍金涡轮盘，组织与性能全部满足技术标准要求，其晶粒组织比传统模锻的大型涡轮盘晶粒组织更加细小，而且不同部位的晶粒组织比较均匀。Based on the study of ESR technology for superalloy ingots, the largest domestic superalloy ingot of GH2674 with 900mm diameter was successfully produced. A new forging technology named zoning forging was developed to manufacture successfully the super large gas turbine disk with the diameters of 1840 - 2118 mm by making use of a 4000t high speed forging press. The structure and property of the extra - large gas turbine disks of GH2674 alloy manufactured by zoning forging met the standard requirement, its grain size was thinner than that of the turbine disks produced by traditional technique, and the micro structure distributed uniformly in different areas.
