| Abstract: | This paper introduces a technology of replacing manufacturing with gas cutting in blanking ring plate of 1000MW turbine generator frame,which can make the ring plate rabbets lain in a straight line after gas cutting and ensure the concentricity of 11-meter-high frame not to exceed 3mm after the combined welding.It can greatly reduce manufacturing costs and improve production efficiency,and the appearance and size of the generator can meet all drawing requirements. |
