Abstract: The squeezing and deviation-correction roller at the outlet of acid tank of the CT unit for silicon steel is one of the most critical devices in the entire operation line. Its working environment is harsh, and it is usually difficult to maintain effectively. Frequent failures have brought great troubles to the stability of production and operation. Once the strip breaks, abnormal operations by operators will lead to a doubling of safety risks. Focusing on how to reduce bearing failures, a new type of fluid-blocking device for the squeezing and deviation-correction rollers at the outlet of acid tank was described and compared with traditional fluid-blocking devices in this paper. Combined with the usage situation after the implementation of the device, the good effect of this new device is proved and it is worthy of further promotion.

Key words: squeezing and deviation-correction roller, bearing, fluid-blocking device
