タイトルまたは説明
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
- 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.
- Requirement on materials properties and
non-destructive tests of MW grade large wind turbines are harsh.
- 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.
- 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
- 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,
- 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
