一、前言近几年来,冷轧卷的消费量急剧增加,特别是轻工市场需求很大。民用建筑等以钢代木,自行车,洗衣机,电冰箱、搪瓷制品、钢木家俱等大幅度增加,带钢的需求远远不能满足。1985年全国板带钢的消费量将达500～550万吨,国内产量差之过多,要求我厂大量增产。但我厂精整各横切机组存在着设备,工艺、包装等方面许多困难,只有重卷机组运行较为顺利,潜力很大,且要求以卷状交货的市场正迅速增长,因此,如何相对地减少剪板的数量,扩大冷轧重卷机组的生产,采取措施,挖掘潜力,实为当务之急。二、重卷机组概况及工艺参数重卷机组位于单、双平整机后,是将平整后的钢卷经本机组检查、切边、涂油,并
I. Introduction In recent years, the consumption of cold rolled coil has increased dramatically, especially in light industry. Civil construction and other steel on behalf of wood, bicycles, washing machines, refrigerators, enamel products, furniture, steel and so greatly increased, the demand for strip is far from satisfied. In 1985 the national strip steel consumption will reach 500 ~ 550 million tons, the domestic output is too poor, requiring a substantial increase in production of our plant. However, we have many difficulties in finishing the crosscutting units in terms of equipment, process and packaging. Only the rewinding unit runs smoothly and has great potential and the market for delivery in roll form is rapidly growing. Therefore, To reduce the number of Jianban, to expand the production of cold rolling re-rolling unit, to take measures to tap the potential, it is imperative. Second, re-roll unit overview and process parameters Recoil unit is located in a single, double-level machine, the flat coil after the unit inspection, trimming, oiled and
