一、前言金属镀层钢板的生产代表带钢生产量的增长比例与国民经济发展的水平。随着冷轧工艺技术的改进,金属镀层钢板工业也不断获得新的发展。近年,镀层钢板的生产特点是带钢操作连续化,这样有利于实现大型化、高速化与自动化。其产品的色泽、结构与厚度等在不同批次之间也是均匀的。金属镀层钢板的主要优点是可以根据不同的使用条件,选择适当的镀层材料与工艺方法以获得不同的耐 I. Introduction The production of metal-coated steel plate represents the growth ratio of the output of steel strip and the level of national economic development. With the improvement of cold-rolling technology, the metal-coated steel plate industry has also been continuously new development. In recent years, the production of coated steel plate is continuous operation of the strip, which is conducive to the realization of large-scale, high-speed and automation. The color, structure and thickness of its products are also uniform among batches. The main advantage of the metal-coated steel plate is that it can be selected according to different conditions, the appropriate coating materials and processes to get different resistance
