Description:

Graphite have good thermal conductivity and it can help decrease the inner heat stress in the rolls. Meanwhile the existence of free punctiform graphite can lower the heat crack so that it can improve the ability against high heat.

Our graphite steel rolls have good wear resistance, thermal cracking, biting and fracture resistance.We adopt static, static cast slot, and a combination of casement, three methods to produce graphite steel rolls.
