复合式冷轧线
摘要：
一种复合式冷轧线，包含一个进料单元、一个接续于所述进料单元的下游的第一轧延单元、一个接续于所述第一轧延单元的下游的退火除锈单元、一个接续于所述退火除锈单元的下游的酸洗单元、一个接续于所述酸洗单元的下游的第二轧延单元，及一个接续于所述第二轧延单元的下游的退料单元。所述第一冷轧机可在进行退火酸洗制程之前先进行初步的轧延，不但可使第二次轧延所需轧制的厚度降低，而能连续性的生产高产出率的大量冷轧薄硬板钢卷，且因初步轧延后的黑皮钢卷可减少30～70％的锈皮量，从而可减少除锈设备的数量及长度，除设备成本降低外，还可减少喷砂、酸液的使用与排放量，达到节能减废之环保效能。
摘要（英）：

A composite cold rolling line includes a feed unit, a first rolling unit at downstream of the feeding unit, an annealing and descaling unit at downstream of the first rolling unit, and a pickling unitat downstream of the annealing and descaling unit, a second rolling unit at downstream of the pickling unit, and a back-feed unit at downstream of the second rolling unit. The first cold rolling millcan perform preliminary rolling before the annealing and pickling process. The product can reduce the thickness of the rolling required for the second rolling, produce a large amount of Cold-rolled thin hard-coated steel coils with continuous high productivity. Due to the initial rolling, the black-skin coils can reduce 30 to 70% of the amount of rust, reduce the number and length of rust removalequipment. In addition to equipment cost reduction, sand blast, usage of acid liquid and discharge of acid are reduced, and the environmental protection effects of energy saving and waste reduction are realized.
