新建年产228万吨连续式冷轧带钢车间工艺设计 摘　　要 进入新世纪以后，为适应经济的迅速增长，中国钢铁工业的结构调整取得了显著成效。在品种结构调整中，以增加板带生产能力，提高板带产品的比例最为引人瞩目。但是，2005年在钢材总产量已达3.71亿吨的情况下，冷轧宽板带（包括涂镀板）的产量却仅为2738吨，仅占钢材总产量的7.4%，大大低于美国在2002年和日本在2003年的比例同时，2005年我国冷轧板带（包括涂镀板、电工钢板）的进口数量高达1396.4万吨。这说明，为保证我国经济的健康发展和工业建设的需要，增加冷轧板带生产将是今后钢铁工业调整的重要组成部分。 根据设计任务书的要求，拟新建年产量2万吨的冷轧薄带钢车间，产品最小厚度为0.25mm，最大厚度为2.50mm。本设计中，采用了大量的先进工艺技术装备如酸轧联合机组技术厚度控制技术张力控制技术板形控制技术，连续退火技术，连续热镀锌技术，这些技术都为生产高产量高品Process design of a newly built cold-rolled strip plant with annual capacity of 2.28 million tons Abstract After we enter the new century，To meet the rapid growth of economic，China steel industry restructure made remarkable progress。In a variety of structural adjustment，To increase the capacity and improve the board with a product of the most conspicuous。But in 2005 in steel production reaches 0.371 billion tons of cases, with a plate of cold - rolled production was only 2738 tons, the total only of 7.4% . Much lower than the united states 2002 and the japan in 2003 in the proportion. This shows that in order to ensure the health of our economic development and industrial development needs, cold rolled strip production will be increased with the steel industry is an important component of the adjustment According to the requirements of design program,we plan to build a new cold rolling strip workshop with annual output of 2.32 million tons. Minimum thickness of the strip is 0.25mm and the maximum thickness is 2.5mm.In this design,we use numbers of advanced technologies and equipments,such as pickling line combined with tandem cold rolling mill (PL-TCM) technology, thickness control technology, tension control technology, shape control technology,continuous annealing technology,continuous hot-dip galvanizing technology and so on. These technologies will bring security to high production and good quality of cold rolling strip.
