Product Description
Graphite cast steel roll
Description
The graphitic steel rolls hae a metallographic structure consisting of carbides and a small amount of graphite in he pearlitic matrix. The rolls of this material has tensile strength and better resistance to thermal cracking than adamite rolls of the same hardness, and the wear resisitance of which is better than the cast steel rolls.
Chemical Analysis
Physical Properties
Microstructure
Microstructure of working layer in the barrel: perlite + carbide/fine pearlite + small percentage bainite + carbide
Application
Roughing, intermediate stands of section mill and bar mill, roughing stands of high-speed wire-rod mill, roughing stands of hot strip mill, vertical rolls, back-up rolls sleeves, straightening rolls
