Centrifugal casting iron mill rolls for hot rolling machine
1)centrifugal casting machine Features
The feature of this casting roll is that it shaped into graphite ball and its performances can be compared with that of alloy infinite chilled roll, and its intensity is higher than that of infinite chilled one, so it is usually used for rest energy casting.
