连退炉辊断轴分析与全生命周期运维管理OA

The cold rolling continuous annealing furnace is key equipment in strip production and processing.It requires matching corresponding control temperatures and atmospheres according to different processes,enabling the metal to achieve the required heat treatment effect inside the fur-nace through processes like preheating,heating,holding,and cooling.The furnace rollers are im-portant devices within the furnace.Once a shaft breakage failure occurs,it necessitates a series of repair procedures including cooling down,roll extraction,replacement,and heating up,which are difficult to handle,have long recovery cycles,and cause severe downtime losses.Through the analy-sis of the causes of shaft breakage in enclosed annealing furnace rollers,a lifecycle operation and maintenance management plan for furnace roller equipment was formulated,and targeted improve-ment measures were proposed to avoid similar accidents from recurring and to ensure the efficient and stable operation of the continuous annealing production line.
