Process procedure:

Forging process flow quality control: Raw material steel ingot into warehouse(test the chemical content) → Cutting→ Heating(Furnace temperture test) → Heat treatment after forging(Furnace temperture test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal diamention, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment

Hydro-electric installation use the hydraulic power drive the water turbine turning. The hydroenergy turn into mechanical energy go through the hydraulic turbine main shaft, magnet yoke, thrust block and some other critical component connection. When connect the hydroturbine and electric generator, the power will be send out follow with the hydroturbine turning. And then the mechanical energy turn into electric energy.
