一、前言镀锌钢板的耐腐蚀性和加工性能优良,它是当前金属镀层钢板中发展最快、应用最广的产品之一。 1936年波兰人森吉米尔设计的森吉米尔连续热镀锌机组在美国投产以来,钢板热镀锌工艺由单张镀锌发展到成卷连续镀锌,使热镀锌钢板的生产得到迅速发展。现在,全世界镀锌钢板的产量已超过2000万吨/年。。随着热镀锌工艺的不断改进和发展,机组速度不断提高,可达到350米/分,为冷轧-镀锌联合生产提供了可能性,美国于1978年建立了第一套冷轧-镀锌联合生产机组。近年新建的带钢热镀锌机组年生产能力超过七十年代
First, the preface Galvanized steel corrosion resistance and excellent processing performance, it is currently the fastest growing metal coating plate, one of the most widely used products. In 1936, the Sendzimir continuous hot-dip galvanizing plant designed by Sezmir in Poland started its production in the United States. The hot-dip galvanizing process from galvanized steel sheet to continuous galvanized steel sheet has led to the rapid development of hot-dip galvanized steel sheet production. Now, the world’s production of galvanized steel has more than 20 million tons / year. . With the continuous improvement and development of the hot-dip galvanizing process, the speed of the unit is continuously increased to 350 m / min, which offers the possibility of co-production of cold rolling and galvanizing. The United States established the first cold rolling-plating Zinc joint production unit. In recent years, the new strip galvanized unit annual production capacity of more than seventies
