Middletown钢厂的五机架2185毫米冷连轧机的设计工程是在1967年8月开始的,1968年4月开始建造,1970年9月15日轧出了第一卷带钢。这台558毫米/610毫米和1575×2185毫米的五机架冷连轧机安装在38.2米宽,207米长的厂房里,其最高轧制速度为1580,/分,能将1.778～5.08毫米厚的带钢轧成厚度为0.305～3.42毫米的成品带材,输入设备能够装运外径为2185毫米、内径为762毫米,重量为44吨的钢带卷。在轧机的输出侧,610～2018毫米宽的带钢被卷成内径为610毫米的带钢卷,轧辊是通过双电枢电机、减速箱和人字齿轮座驱动的。
The design of the five-stand 2185mm Tandem Cold Rolling Mill at Middletown began in August 1967 and began construction in April 1968. The first coil was rolled out on September 15, 1970. The 558mm / 610mm and 1575x2185mm five-stand tandem cold rolling mills are installed in a 38.2-meter wide, 207-meter-long mill with a maximum rolling speed of 1,580 rpm and a capacity of 1.778 to 5.08 mm Of the strip is rolled into finished strip of thickness 0.305 to 3.42 mm and the input device is capable of transporting a coil of steel having an outer diameter of 2185 mm, an inner diameter of 762 mm and a weight of 44 tons. On the output side of the mill, strips 610 to 2018 mm wide are wound into rolls of steel with an inner diameter of 610 mm. The rolls are driven by double-armature motors, gearboxes and herringbone gears.
