Forged Entire CNC Machined Francis Runner
CNC Machined Francis Runner, Francis Runner Band Heat Treatment
Forging could considerably improve metal’s organizational structure and mechanical property.
Forging offers uniformity of composition and structure. Forging results in metallurgical recrystalisation and grain refinement as a result of the thermal cycle and deformation process. This strengthens the resulting steel product particularly in terms of impact and shear strength.
Forged steel is generally stronger and more reliable than castings of same material due to the fact that the grain flows of the steel are altered, conforming to the shape of the part.

Forged Integrally +100% CNC Machining Francis Turbine Runner
1. GETAI has improved the manufacturing procedure of Francis turbine runner which suffered from the problems such as the cavitation and abrasion, welding seam cracks between crown, band and vanes, block worn off from vane etc. The whole Francis runner is forged integrally followed by entire CNC machining to eliminate tiny blowholes and slag inclusions existed on passage surface which accelerate cavitation and abrasion, and solve the potential risk existed by unreleased stress left after welding. The Francis turbine runner service life prolonged consequently.
In the case the high head Francis runner with long and narrow passageway which is hard for entire CNC machining or the runner size exceeds the forging range which can not be forged integrally, GETAI applied a procedure by dividing the runner to two parts which consisted of crown with half vanes and band with rest half, both two parts can be forged integrally with entire CNC machining and welding assembled in final. The welding applied to the middle of vane, where is convenient for single pass welding without touch of potential crack area, the operation security and service life are improved largely.
Samples exhibited below is for forged integrally+100% CNC machined Francis turbine runner (half part) which finished by our five axis linkage CNC machine.
