这里介绍日本住友金属工业公司在鹿岛钢厂安装的大型轧机。该轧机于1975年4月开始试轧,现已达到第一阶段生产指标,每月66700吨,以后将达到每月100000吨。可轧制板桩钢、工字钢和槽钢。整个生产线(包括轧制线和精整线)完全由计算机控制。已经得到了一系列的好处,例如节省劳动力(已减少了29个操作工和检验员)、效率高、速度快且维修简易。 坏料重量为1500～2600kg,长度为3500～10500mm,在这个轧机轧制成各种各样的工字钢、角钢、槽钢等等,尺寸为100×50mm～600×300mm,长度为5m～
Here is a brief introduction of the large-scale rolling mill installed by Sumitomo Metal Industries Co., Ltd. at Kashima Steel Works. The mill started trial rolling in April 1975 and has now reached the first stage production target of 66,700 tons per month and will reach 100,000 tons per month thereafter. Rolled sheet steel, I-beam and channel. The entire production line (including the rolling line and finishing line) is completely computer controlled. A number of benefits have been achieved, such as labor savings (a reduction of 29 operators and inspectors), efficiency, speed and ease of maintenance. The weight of bad material is 1500 ~ 2600kg, the length is 3500 ~ 10500mm, rolled into a variety of I-beam, angle steel, channel steel and so on in this rolling mill, the size is 100 × 50mm ~ 600 × 300mm, the length is 5m ~
