Graphite steel roll 160 (GS160) for roughing mill is a common roll material with high graphite content, which makes the roll have good self-lubricating and thermal conductivity, which is beneficial to reducing friction and heat accumulation and extending the life of the roll. service life. It has good wear resistance and can withstand the friction and wear of the metal blank during high-speed rolling. It can withstand large rolling pressure and impact load. Graphite steel rollers 160 (GS160) for roughing mills have wear resistance and high strength. , cost-effectiveness, and other advantages, it is a commonly used roll material with good performance and is widely used in the field of metal processing.
