1.Dimension:253 X230X130 Weight:18.9Kg

2. Material: Ductile cast iron -50 GOST 7293-85

Correspond between T500-7 and QT600-3 of GB/T1348-2009

3.Circumferential machining

4. Heat Treatment Method:High Frequency Quenching Surface Hardness :350-450HB

5. (GB11)Accuracy of casting: 11T-0-0-10 GOST P53464-2009

6. Mass content of the elements:

7. Mechanical Property requests:

9. Molding Method: Resin Sand Metal Hand Molding

10. Melting Method: Medium Frequency Induction Furnace Melting

11. Spheroidization Treatment Method:

(1) Strictly Control the Oven Material, avoid to form strongly carbonization elements such

as Cr.,V. , Mo etc. Mn remove low limit, prevent from free cementite as- cast state

(2)Amount of Preparation, (0.5--0.7)%, one hand prevent from Carbonization , other hand prevent from forming amount of ferrite.

(3) Add appropriate amount of Cu stable pearlite, (0.3-0.4)%

12. Heart Treatment Method: High Frequency Quenching(The aim is getting martensite structure from casting surface, can improve abrasion resistance of

casting surface, same time can keep cast heart in good formability and tolerance)

Adopting Frequency 10KHz---2MHz Power Density 10.9—18.6W/mm2,Medium:Water Quenching Temperature:(900-925°C)

13. Chemical Elements Test: Arrange chemical elements test through direct-reading spectrometer(GOST 7293-85)
