Wrapper roll for recoiling machine in CPS (Compact Trip Roduction) production line and lubricating method thereof

Abstract

The invention discloses a wrapper roll for a recoiling machine in a CPS (Compact Trip Roduction) production line. The recoiling machine comprises stand rolls, a lower pinch roll and an upper pinch roll. A plurality of wrapper rolls and a recoiling machine mandrel form a sheet recoiling mechanism; the wrapper rolls are arranged on a machine base through bearings and bearing bushings; sealing rings and bearing inner end covers are respectively arranged at two ends of each bearing; the sealing rings are fixedly connected with the wrapper rolls; the bearing inner end covers are fixedly connected with the bearing bushings; and each sealing ring and each bearing inner end cover form a sealing structure through water retaining rings in a concave-convex matched manner. The invention also discloses a lubricating method for the wrapper roll. By adopting the technical scheme, the automatic oil supplementing and lubricating effect of the wrapper roll is greatly improved; the wrapper roll can operate soundly; the overflow phenomenon can be avoided; the on-line life is greatly prolonged; cooling water of the upper pinch roll is reformed so as to reduce a water inlet source of the wrapper roll and a water inlet amount of a bearing block of the wrapper roll and delay the emulsification of an oil product in the bearing block; and the economic loss caused by steel piling of the recoiling machine and even unplanned pouring stop accidents is reduced.

Description

technical field [0001] The invention belongs to the technical field of metallurgical industrial production, and relates to the technology of continuous casting and rolling of thin slabs. More specifically, the invention relates to a coiling auxiliary roll for a coiler of a CSP production line. In addition, the present invention also relates to the lubricating method adopted by the winding aid roller. Background technique [0002] CSP is a technology of thin slab continuous casting and rolling in the metallurgical industry, and it is the compact strip production technology (CSP, Compact trip production) of SMS (SMS). The CSP process has the advantages of short process, simple and stable production, good product quality, low cost, and strong market competitiveness. my country's Handan Iron and Steel Company and Zhujiang Iron and Steel have CSP continuous casting and rolling production lines. [0003] The product directions developed by the American Dinanometer CSP plant: ste...
