Large casting

الوصف

Ductile iron is mainly applied in wind turbine products,Frame wheel hub, and bearing housing are core accessories in wind turbines . They are manufactured by resin san molding ,smelting,and casting.
Main steel grade :EN-GJS******8U-LT,EN-GJS******2U-LT.
 
Clients are required to offer their drawings and technical requirement, Which will transferred to technical department(heat treatment center, large forgings research center, mechanical research center, and welding department, etc,) for confirmaion and accounting, Then we will offer you the quotation, The ordered products will be put into production as soon as possible after clients have placed an order.  For any problems rasied in the product line ,We will contact and disscuss with our clients directly
 
Properties of casting for wind turbine

1. Since the service time of wheel hub ,frame and bearing housing is required to be over *0 years,and the replacement cost of these vital parts is rather high ,the quality requirements upon casting are extremely high.
2. Requirement on materials properties and non-destructive tests of MW grade large wind turbines are harsh.
3. We will control the castings quality from smelting ,non-destructive test and machining aspects according to the products structure and technical requirement clients have provided,

Our 1.5MW and 2.5MW series castins have met the needs of various companies,like Senvion,
SANY heavy Industry, Shanghai Eletric, Huachuang,Huayi, Swiss Electric, GEOHO,and Nanjing Wind Power Technology Company.

4. Gray iron castings are generally used for lathe bed ,internal combution engine, diesel engine,

And ingot mold; we have ever provided **0t machine tool for Qiqihar Heavy CNC Equipment company.

Quality control

1. The leading development trend of wind turbine is to turn to large size gradually. This has raised higher requirement for castings wall thickness and materials, By modifying the manufacutring techniques , we modify the graphite morphology to obtain a kind of ductile iron whose elongetion, impact value,tensile strength reaches or exceeds the standard value,
2. For wind turbine products with high processing needs , we employ riser technique to ensure the raw materials high purity and uniform components.

TongYu commits that our casitng products meet the non-destructive standards,and possess the properties superior than standard level
