原西德山德威格机器制造公司制造的20辊轧机采用4立柱式设计,直接液压压下系统,同时配有轧辊倾斜、弯辊和单个中间辊轴向移动等技术。它能提供精确的辊缝形状和带钢板形控制,以大压下率和高轧制速度生产薄规格宽带钢。另外,轧机还配备了带钢冷却和干燥系统以及换辊机器人。 The original 20-roll mill manufactured by Sandvig, a West German company, features a 4-column design with a direct hydraulic pressure reduction system that incorporates roll axising, bending rolls and a single intermediate roll for axial movement. It provides precise roll gap shape and strip shape control to produce thin gauge wide strip at high reduction rates and high rolling speeds. In addition, the mill is equipped with strip cooling and drying systems as well as roll change robots.
