Graphite steel roll for profile mills 150 is a roll made of graphite steel suitable for finishing and cold rolling in profile mills. Excellent wear resistance, which can extend the service life of the roll and reduce production costs. It can withstand shock and vibration under high temperature and pressure and is not prone to thermal cracks and breakage. It has good dimensional stability and is not easy to deform, ensuring the accuracy and quality of rolled products. It has good thermal conductivity, can quickly dissipate heat, reduce thermal deformation of the rollers, and improve the quality of rolled products. Used for rolling high-strength, high-precision steel sections. Higher dimensional accuracy ensures the quality of profile products.
Hardness HSD: 40-50
