Φ150×250mm二辊冷轧机在生产中一直普遍存在着一个突出的“烧瓦”问题,严重影响着轧机的正常生产。为解决这一问题,采用SF-2复合材料的轴承。这不仅能解决“烧瓦”现象,而且使用寿命可成倍地提高。本文阐述了SF-2复合材料的使用特性;试验过程及结果;SF-2轴承的优越性和经济效果等。这种材料的使用和经济价值较明显,对我国轧机改造具有现实意义。 Φ150 × 250mm two-roll cold rolling mill in production has been a prominent “burning tile” problem, seriously affecting the normal mill production. To solve this problem, using SF-2 composite bearings. This not only solves the phenomenon of “burning tile”, but also prolongs the service life by several times. This article describes the use of SF-2 composite properties; test process and results; SF-2 bearing the superiority and economic effects. The use of such materials and economic value is more obvious, the transformation of our mill has practical significance.
