一、工程概况宝钢冷轧厂从日本新日铁公司引进的冷轧带钢连续退火工艺线,是把冷轧带钢的酸洗清理、退火时效、光洁平整、检查重卷等分别进行的工艺处理过程有机的组合在一起,形成一个连续的流水生产线,从而使冷轧带钢的生产技术、生产工艺发生了根本性的变革,为冷轧带钢生产开创了新局面。与罩式退火炉比较其产量可提高几十倍。连续退火炉是连续退火工艺生产线的一个重要组成部分,它由七个相对独立的炉室组成(如图1)。各炉室的功能及炉衬结构如下:
First, the project overview Baosteel cold-rolled steel plant from Japan’s Nippon Steel Company introduced cold-rolled strip steel continuous annealing line is the cold-rolled strip pickling cleaning, annealing aging, smooth formation, check re-roll, respectively, the process The process of organic combination of the formation of a continuous flow line, so that the cold-rolled strip steel production technology, production processes have undergone fundamental changes, creating a new situation for cold-rolled strip production. Compared with the hood annealing furnace its output can be increased several times. Continuous Annealing Furnace is an important part of continuous annealing process line, which consists of seven relatively independent furnace chamber (Figure 1). Each furnace function and lining structure is as follows:
