随着钢铁工业、橡胶塑料工业、造纸工业的发展,对各种冷硬铸铁轧辊、钢辊,及辊筒表面的光洁度要求越来越高。工件直径越大,要求光洁度越高,加工起来就越困难。国内对光洁度要求▽12～▽14的中小直径的辊体加工已经解决,但对于大直径的如尺寸为φ700×1800毫米的冷硬铸铁轧辊及其它辊类,光洁度达到▽12,还没有成熟的经验。目前,一般用磨削的方法达到▽10以上的光洁度是很不容易的。本文就辊表面的高光洁度加工的几种方法做一综述。
With the development of the steel industry, rubber and plastics industry, and paper industry, the requirements for finish of various chilled cast iron rolls, steel rolls and roller surfaces are getting higher and higher. The larger the diameter of the workpiece, the higher the required finish, the harder it is to process. The domestic small and medium diameter roller body finishing requirements ▽ 12 ~ ▽ 14 have been solved, but for the large diameter, such as the size of φ700 × 1800 mm chilled cast iron rolls and other rollers, finish ▽ 12, not yet mature experience. At present, the general method of grinding to ▽ 10 finish is not easy. This article reviews several methods of high finish machining of roll surfaces.
