Maintenance
After rolling one short period,the hardness of rolling surface arise 3-4 HRC and strain hardening layer producing causes fatigue effect,which brings crack and spalling.The only way to decrease the possibilities of crack and spalling,elongate the roll¡¯s life is to remove the phase-transformation layer in advance. |
