万能轧机由于具有一系列的优点,在国内外轧钢生产中得到愈来愈广泛的应用。然而,现有的这些轧机结构复杂、体积庞大,它们的工作原理不适用于小型横列式轧机。近年来,小型异形经济断面钢材的需要量日益增加,这些断面的特点是薄壁、宽腿、小斜度以至无斜度(见图1)。用普通两辊轧机很难达到上述这些要求,因此迫使 Universal rolling mill due to a series of advantages in rolling at home and abroad have been more and more widely used. However, the existing rolling mills are complex and bulky, and their working principle is not suitable for the small-sized rolling mill. In recent years, the demand for small profiled section steel has been increasing. These sections are characterized by thin walls, wide legs, a small slope, and even no slope (see Figure 1). With ordinary two-roll mill is difficult to achieve these requirements, thus forcing
