Introduction:
The performance of the Graphite roll is similar to the Adamite roll. The distinctive difference between them is that fine graphite exists in Graphite Steel Roll, which can improve the resistance to spalling and the adhesion of mill scrap.
The graphite in Graphite Steel Rolls acts as a lubricant between the roll and the metal being rolled. This reduces friction and wear, which can lead to spalling and other forms of damage. Graphite Steel Rolls are also more resistant to thermal shock and thermal fatigue due to their improved thermal conductivity and thermal expansion properties.
