一、绪言彩色涂层钢板,亦称预涂钢板,因涂敷在成型加工之前而得名。它是以普通冷轧板、镀锌板或铝板为基板,表面涂敷有机涂料、溶胶或贴塑料薄膜等,由彩色涂层钢板生产线生产的产品。它既有绚丽的外观,又有强耐蚀性和优良的加工性,是轻工、建筑、船舶、铁路交通等行业的理想用材。自30年代问世以来,短短几十年在国外取得了令人触目的发展。彩色涂层钢板(以下简称彩板)在我国几乎是一项空白。面对国内外广阔的彩板需求市场,武钢急用户所急,经国家批准,率先从英国引进一条生产设备先进的、产品多种类的连续生产作业线。1987年11月生产出了第一卷彩板。这条生产线以较快的建设速度、以较小的投资生产出了合格的彩板,这
First, the introduction of color coated steel, also known as pre-coated steel, because of the coating before forming the name. It is based on ordinary cold-rolled plate, galvanized sheet or aluminum substrate, the surface coated with organic coatings, sol or paste plastic film, etc., from color coated steel production line products. It is both beautiful appearance, but also strong corrosion resistance and excellent processing, light industry, construction, shipbuilding, railway transportation and other industries the ideal timber. Since its introduction in the 1930s, it has achieved impressive development abroad in just a few decades. Color coated steel (hereinafter referred to as color plate) is almost a blank in our country. Faced with the vast domestic market demand for color plates, Wugang urgent user urgency, approved by the state, the first from the United Kingdom to introduce an advanced production equipment, product variety of continuous production line. November 1987 produced the first roll of color plates. This production line with a faster construction speed, with a smaller investment to produce a qualified color plate, which
