BH3 forged steel roll changes traditional，heat treatment processes and increases the content of elements such as C, Mo, and V,in order to obtain high hardness carbides such as MC, M2C, and M7C3, achieving high wear resistance, high roughness retention, and easy grinding performance
BH3 forged high-speed steel work roll for cold rolling
Some details about forged steel rollers: materials and production
•Material: Usually made of high-strength materials such as high-carbon steel and alloy steel.
•Manufacturing process: including forging, heat treatment, machining and other steps. Among them, forging is a key step, which can significantly improve the density and mechanical properties of the material.
Features
•High strength and hardness: able to withstand heavy loads and suitable for high temperature and high pressure working environments.
•Wear resistance: After special treatment, the surface has good wear resistance and extends its service life.
•Good fatigue resistance: stable performance even under long-term operation.
•Precise dimensional control: Through precision processing technology, the dimensional accuracy of forged steel rollers is ensured to meet the needs of different application scenarios.
