We can supply all kinds of forged rolls and shafts.such as cold rolls, straightener rolls, table rolls, sendzimir rolls continuous mill work rolls
Cold Rolling Mill Work Roll
Forged steel work roll performs as a tool to transform materials under normal room temperature, therefore, it is the most wear and tear spare parts during the rolling process .
Cold Rolling Mill Intermediate Roll
Cold rolling mill intermediate Roll applies to high precision 6-Hi (as well as a few 8-Hi) mill, named from working location between work roll and back-up roll, mainly used to control the shape of strip.
