The present problems, such as uneven feeding, roll body change and hydraulic device instability etc. with 500 t/d of flaker in the process of production, affected the thickness and intensity of the blank, and the frequently outage rate and highly maintenance cost would be brought in. The problems of roll qulity, hydraulic system, feeding and lubrication were analyzed, and the maintenance method was proposed. The attentions in flaker production were expounded. It could provide reference for the maintenance of larger flaker. |
