消除带钢 C90 缺陷，提高连退机组平整机工作效率 1 1 1 1 2 21 庞建国 李 鹏 张红根 许晨光 姚 俊 颜国强 (1.上海宝钢设备检修有限公司;2.宝山钢铁股份有限公司冷轧薄板厂) 摘 要 将连退机组平整机 1 号机架入口除尘装置进行改进，改进后的吸尘装置为 22mm×1200mm 的鸭嘴形吸尘 口，流速可达到25～30m/s，同时增设气动装置将伸缩滑动式吸尘口，在工作时可运动到距支承辊和工作辊相切线 20～30mm 距离，并采用波纹管降低了除尘风管的振动，充分保证除尘效果。进而解决了由粉尘造成的带钢 C90 缺 陷，机组速度也由原来的300mpm 提高到 500mpm，一方面速度的提高增加了生产效率，另一方面也降低了平均生 产成本。该改进方法不但解决了机架内带钢 C90 缺陷的存在，并移植到的平整机除尘系统大规模改造中。 关键词 除尘装置 吸尘口 带钢 C90 缺陷 气动装置 Solved the Steel C90 Defect ，Increase the Production Efficiency of the Levelling Machine Pang Jianguo Li Peng Zhang Honggen Xu Chenguang Yao Jun Yan Guoqiang (1.Shanghai Baosteel Equipment Maintenance Co., Ltd.; 2.Baoshan Iron Steel Co.,Ltd.) Abstract Improve the entrance dusting device of the levelling machine No 1 body frame, the shape of a vacuum cleaner of the improved mechanism is 22mm×1200mm, velocity reaching 30m/s. Also providing pneumatic, which can be telescoped sliding a vacuum cleaner. It can be moving to the work rolls and rolls tangent line 20mm distance, dusting down the wind by using Surface of tube,adequate assurance the effect of dusting, and solving the steel C90 defect Caused by dust, the crew speed promoted from the original 300mpm to 500mpm, increase of the rate improued production efficiency, also reduced the average cost of production. The improvement not only solved the steel C90 defect in the body frame but also transplanted to the large-scale reform of the levelling machine dusting system.
