带钢冷轧或表面平整轧制通常采用单一润滑剂进行润滑、冷却和表面清理。为了提高带钢表面质量,提高生产率和轧制工艺的灵活性,并且更好地控制生产工艺,德国SMS西门子公司与REBS公司共同开发了一种小剂量润滑系统,并配备有施加液氮或低温氮的装置以清洁轧辊及带钢表面。新系统主要安装在轧辊咬入口处,并在出口处(如果需要,也可在进口端)提供液态或低温惰性气体(例如氮气)来清洁轧辊及带钢。
Strip cold rolling or surface smoothing usually uses a single lubricant for lubrication, cooling and surface cleaning. In order to improve the quality of the strip surface, increase the productivity and the flexibility of the rolling process, and to better control the production process, Germany SMS Siemens and REBS jointly developed a low-dose lubrication system equipped with liquid nitrogen or low temperature Nitrogen device to clean roll and strip surfaces. The new system is mainly installed at the bite entry point of the roll, and provides liquid or low temperature inert gas (eg nitrogen) at the exit (and also at the entry end, if required) to clean the rolls and strip.
