Heat Treatment Heavy Forged Steel Shaft Hydropower Spindle
Description:
The forged steel shaft-hydropower spindle forging is widely used for large scale hydropower equipment industry. For example: Alstom, Voith Siemens Hydro Power Generaion, Ha’erbin Hydropower group, Toshiba Hydro power and so on. The products conform to Standard of ASTM A668/A668-96 and JB/T1270-2002.
The manufacturing equipment is 30~185MN hydraulic press, the forging ratio >4.5, the technical condition is in accordance with the standard of ASTM A668/A668-96 and JB/T1270-2002.
The product can be provided as per your drawing or specified requirements.
Smelting Process:EF+LF + VD
The process as follow :Ingot →heat → forging → Heat treatment (Normalizing+ tempering) → Inspection →rough machining→UT →finishing machining →Inspection
Applications: The forged steel shaft-hydropower spindle forging is widely used for large scale hydropower equipment industry.
