所谓簧锌彩涂联合生产线,是基板上卷后先经镀锌工序,然后再进入彩涂工序。

其主要特点是:
  (1)省去了镀锌线出口段原有的钝化和涂油工序
  (2)省去了彩涂线的脱脂清洗工序;
  (3)省去了从镀锌到彩涂线的运输过程中的人力、物力和时间。
  联合生产线通常会在镀锌和彩涂工序之间设有拉弯矫直设备,保证进入彩涂段的版形质量,使彩涂不会出现漏涂等质量问题。但这种机组布置形式因设备台数多且复杂,增加了故障停车的概率,容易出现产品质量事故。镀锌彩涂联生产线又分热镀锌一彩涂联合生产线(图1-8)和电镀锌一彩涂联合生产线两种,两种联合生产线的彩涂部分的工艺是一样的,只是前端设备的组成即镀锌部分有所不同,一个为热镀锌,另一个为电镀锌等两种不同的工艺。据资料介绍,我国已有多条中小型的电镀锌一彩涂联合生产线,上规模的热镀锌一彩涂联合生产线目前还没有已上马的项目。

彩色钢板生产线经过50年的漫长发展,其生产线速度已从最初的15m/min发展到现在的240m/min,板厚可在0.15~2.2mm之间,板宽最大可达2000mm。20世纪末,全世界已有400多条彩色钢板生产线,单美国就有200多条,全世界的总生产能力已达到1400万t
  在美国的工艺技术影响下,20世纪60年代初,欧洲、日本已有多条彩色涂层钢板连续生产线相继投产。特别是日本,在早期引进了美国的先进技术后,不断消化吸收、改进到再建造,使彩色钢板的产量快速提高,到70年代末,其年产量就已达到200万t,跃升为亚洲彩色钢板生产的领头羊。
  为了更进一步推动彩色钢板事业发展的网络化,美国早在1962年就成立了世界上最大的卷板涂装联合企业一一美国国家卷材涂装者协会(NCA),该企业是集卷板涂层的工艺技术交流、卷板和涂层原料贸易、涂层设备供应、产品买卖等信息于一体的国际性组织。该组织成员包括彩色涂层钢板的生产厂所需原材料(如涂料、金属卷材)和设备的生产厂。除定期举行会员大会讨论交流情况外,还组织专题技术论坛和新产品设计竟赛以推动彩色涂层钢板的发展和开拓市场,并收集和发布生产和销售的统计数字,制定和出版有关标准、技术手册和刊物,对彩色涂层钢板的发展起到很好的促进作用。目前,其成员数量已达到160多个,来自世界各地规模较大的彩色钢板和彩色铝板的生产、制造企业,我国宝钢公司是其中一员,该组织规模颇为宏大。
  在欧洲,卷材涂料在1960~1965年期间已经发展得非常成熟,1966年,欧洲已经有14条彩色钢板生产线,分布于瑞典、德国、英国、比利时、瑞士和法国等多个国家。1967年,欧洲卷材涂层协会(ECCA)在比利时的布鲁塞尔成立。这个基于科技发展的协会由80多个卷材涂层商、50多个涂料生产厂、40家原材料供应商和20多家设备制造商组成。协会的宗旨是研究和推广彩色涂层钢板的生产和使用。20世纪末,欧洲的彩色涂层钢板年生产总量已达390万t

The so-called spring zinc color coating joint production line is the process of galvanizing and then color coating after the base plate is rolled on.
Its main features are:
(1) The original passivation and oiling procedures of the exit section of the galvanizing line are omitted
(2) The degreasing and cleaning process of the color coating line is omitted;
(3) It saves manpower, material resources and time in the transportation process from galvanizing to color coating line.
The joint production line is usually equipped with stretch bending straightening equipment between the galvanizing and color coating processes to ensure the quality of the plate shape entering the color coating section, so that the color coating will not have quality problems such as missing coating. However, because of the large number and complexity of equipment, the layout of this unit increases the probability of fault shutdown and is prone to product quality accidents. Galvanizing color coating joint production line is divided into hot galvanizing color coating joint production line (Figure 1-8) and electro galvanizing color coating joint production line. The color coating process of the two joint production lines is the same, but the composition of the front-end equipment, i.e. galvanizing part is different, one is hot galvanizing, the other is electro galvanizing and other two different processes. According to the data, there are many small and medium-sized zinc plating and color coating joint production lines in China, and there is no project on the scale of hot-dip galvanizing and color coating joint production line.
After 50 years of long development, the production line speed of color steel plate has developed from the initial 15m / min to the current 240m / min. the plate thickness can be between 0.15-2.2mm, and the maximum plate width can be up to 2000mm. At the end of the 20th century, there are more than 400 color steel plate production lines in the world, more than 200 in the United States alone, and the total production capacity of the world has reached 14 million tons
Under the influence of American technology, in the early 1960s, many continuous production lines of color coated steel plates have been put into production in Europe and Japan. Especially in Japan, after the introduction of advanced technology from the United States in the early stage, the production of color steel plates was rapidly increased by absorbing, improving and rebuilding. By the end of the 1970s, the annual production of color steel plates had reached 2 million tons, becoming the leader of color steel plate production in Asia.
In order to further promote the network development of color steel plate industry, as early as 1962, the United States established the world's largest coil coating joint enterprise, the national coil coating Association (NCA), which is an international organization integrating coil coating technology exchange, coil and coating raw material trade, coating equipment supply, product trading and other information. The members of the organization include raw materials (such as coatings, metal coils) and equipment manufacturers for the production of color coated steel plates. In addition to holding regular meetings to discuss and exchange information, special technical forums and new product design competitions are also organized to promote the development and market development of color coated steel plates, collect and publish statistics of production and sales, formulate and publish relevant standards, technical manuals and publications, which play a good role in promoting the development of color coated steel plates. At present, the number of its members has reached more than 160, coming from large-scale color steel plate and color aluminum plate production and manufacturing enterprises all over the world. Baosteel company of China is one of them, and the scale of the organization is quite large.
In Europe, coil coating has developed very mature from 1960 to 1965. In 1966, there were 14 color steel plate production lines in Europe, which are distributed in Sweden, Germany, Britain, Belgium, Switzerland, France and other countries. In 1967, ECCA was founded in Brussels, Belgium. This association based on the development of science and technology is composed of more than 80 coil coating manufacturers, more than 50 coating manufacturers, 40 raw material suppliers and more than 20 equipment manufacturers. The aim of the association is to study and promote the production and use of color coated steel plates. At the end of the 20th century, the total annual production of color coated steel plates in Europe has reached 3.9 million tons
