轧制钟表弹簧及钢材、有色金属和合金材料的薄片零件时,采用硬质合金轧辊代替钢轧辊,可显著减少轧制时的摩擦,从而得到光滑的表面,减少工件擦伤和粘附等缺陷,且提高耐磨性几十倍。但是要广泛采用硬质合金轧辊,除受到材料本身的限制外,最主要的是硬质合金轧辊工作表面的精度和光滑度要求较高, Rolling clock springs and thin sections of steel, non-ferrous metals and alloy materials, the use of carbide rolls instead of steel rollers, can significantly reduce the friction during rolling to get a smooth surface, reducing the workpiece scratches and adhesion defects , And improve the wear resistance of several times. However, to widely adopt carbide rolls, in addition to being limited by the material itself, the most important is the high precision and smoothness of the working surface of the cemented carbide roll,
