Specification :

Centrifugal Casting High Speed Steel Rolls:

:Property of rolls: The outer layer is a complicated carbide struture of high-carbon steel alloys containing Cr,

Mo, W, V, Ni and Nb, which is inlaid into the martensite structure, Through contral of carbon conter and

comprehensive heat treatment process, the roll shows optimal wear and thermal fatigue resistant properties and the

oxidate assumes a film struture. The residual strees is also reduced to a minimum.

----------------------------------------
::Benefits from the use of CC-HSS rolls
:quantum rise in both performance and "value in use"
:Higher productivity in both mill and roll shop
:Better end product quality
:Lower roll inventory

------------------------------------
::Mechanical Properties
Hardness of shell HSD 75-85
Hardness of neck HSD 35-48
Tensile Strength of Core >450Mpa

------------------------------------
::Application
Widely used as the F5 and F6 working rolls for narrow strip mills, rod mill,high-speed wire mills,on pre-finish mill stand and bar finish milling dividing-shear stand.
