这种12辊轧机采用了不同于Sendzim ir轧机的整体机架和Sundw ig的四立柱机架,而类似于传统4、6辊轧机的整体机架。机架内装有可上下移动的上下辊箱,每个辊箱内用芯轴固定安装了两大一小三组背衬轴承。轧机在下辊箱内设有直接作用式板形调节装置。轧机采用小抛线型直接作用式液压压下装置。这两台轧机均可将厚3~2.75mm的热轧带钢不经中间退火轧制成0.3~0.2mm成品厚度的冷硬带钢。
This 12-roll mill uses a unit rack different from the Sendzimir mill and a four-post rack from Sundwig similar to the one with a conventional 4,6-roll mill. The rack is equipped with upper and lower roller boxes which can be moved up and down, and two large, one small, three groups of backing bearings are fixedly installed in each roller box by a mandrel. The mill has a direct acting plate-shaped adjusting device in the lower roller box. Mill uses a small throw-type direct-acting hydraulic pressure device. Both mill can be 3 ~ 2.75mm thick hot-rolled strip without intermediate annealing rolled into the finished product thickness of 0.3 ~ 0.2mm cold strip.
