6Mass content of the elements:

7Mechanical Property Request:

8Body Organism: Pearlite + Ferrite

9Molding Method:Resin Sand Metal Hand Molding

10Melting Method:Melted in Medium Frequency Induction Furnace

11Spheroidization 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(900-925) °C

13 Chemical Elements Test: Arrange chemical elements test through direct-reading spectrometer

14Mechanical Property Test(GOST 7293-85)
