酸洗是冷轧带钢生产的重要工序,可以有效去除热轧板的氧化铁皮。随着酸洗工艺和设备的技术发展,一些新的技术和设计方案出现,加之国内酸洗机组接近饱和,改造项目将成为主流。就槽体腐蚀问题,给出了采用PP材料制作槽体的方案;针对酸雾泄漏以及挤干辊窗口漏酸等问题,结合宝钢几条酸洗线工艺段改造项目的经验,在优化槽盖材料的同时采用独立水封设计,对挤干辊窗口采用一体式的滑动对开门设计,有效解决了酸雾和漏酸等问题,对以后的改造项目具有极好的借鉴意义。
Pickling is an important process for the production of cold-rolled strip, which can effectively remove the scale from the hot-rolled sheet. With the pickling process and equipment technology development, some new technologies and design solutions appear, combined with the domestic pickling unit close to saturation, the transformation project will become the mainstream. In the light of the problem of tank corrosion, the scheme of making tank body by PP material is given. According to the problems of acid mist leakage and acid leaking of squeeze roll window, combined with the experience of Baosteel reconstruction project of several pickling lines, Material at the same time using an independent water seal design, extrusion roller window with integrated sliding door design, effectively solve the acid mist and acid leakage and other issues, the transformation of the project has an excellent reference.
