由太原重型机器厂研制的φ1300毫米油膜轴承于1987年12月在舞阳钢铁厂通过技术鉴定。φ1300mm油膜轴承用于4200mm特厚钢板轧机,其承受轧制压力为4200T,是特厚板4200mm轧机的关键基础部件,它具有如下特点:(1)平均比压高,最高可达200～250kgf/cm~2;(2)速度变化范围大,最低小于1米/秒,最高可达30～40米/秒,高速线材轧机每秒可达100米以上;(3)整个轴承便于对轧辊快速拆卸和快速安装;(4)密封装置完善可靠;(5)油膜厚度很薄,而轴承制造、安装精度很高,维护必须精心;(6)轴承径向尺寸小,结构紧凑。
By Taiyuan Heavy Machinery Factory developed φ1300 mm oil film bearings in December 1987 in Wuyang Iron and Steel passed the technical appraisal. φ1300mm oil film bearings for 4200mm thick plate mill, the rolling pressure to withstand 4200T, 4200mm thick plate is the key basis for rolling mill parts, which has the following characteristics: (1) the average high pressure, up to 200 ~ 250kgf / cm ~ 2; (2) The range of speed change is large, the minimum is less than 1m / s, the highest is 30 ~ 40m / s, the high speed wire rod mill can reach more than 100m per second; And rapid installation; (4) perfect and reliable sealing device; (5) thin film thickness, and bearing manufacturing, installation of high precision, maintenance must be meticulous; (6) bearing radial size small, compact structure.
