1)centrifugal cast hardness 72-76HS
2)high precision
3)suitable for steel wire tyre craking

Centrifugal companding casting technology bears the following outstanding advantages:

1.       High structure tightness of solidified rollers prevent almost no defaults as air cavity, air bubble, slag inclusion, etc.

2.       Centrifugal rolls contain almost no metal consumption for the gating and feeding system and thus ensure high efficiency of technical producing.

3.       Centrifugal rollers have more outstanding advantages-including almost no Makou and great convenician in drilling.

4.       Centrifugal companding casting rollers possess high surface hardness (Hs76±2), fine toughness, superior resistance to abrasion and high core strength, and can reach qualified rollers of HT300.

5.       Homogeneous working face and trivial change of hardness (decent change from outside to inside is less than HS5) ensure the steadiness of rollers quality.

6.       Long service life (longer 3~5 times than vertical and still casting rollers) saves considerable capital for the customers.
