针对山东钢铁莱芜分公司冷轧线平整后带钢表面残留平整液斑的问题,结合现场生产实际,从压缩空气的纯净度、空气压力过程波动、吹扫强度不足等方面入手,通过采取增设储气罐、优化设计吹扫管道、改进吹扫梁等措施,大幅降低了平整液斑缺陷,提升了带钢的表面质量,减少了头尾切除量,综合成材率提高了1.65%。 Aiming at the problem of leftover liquid spot on the surface of strip after the cold rolling line of Shandong Iron and Steel Co., Ltd. Laiwu Branch, with the actual production in the field, starting from compressed air purity, air pressure process fluctuations, lack of purge strength, Gas tank, optimizing the design of purging pipelines, improved purging beams and other measures to significantly reduce the plaque spot defects and improve the surface quality of the strip, reducing the amount of head and tail resection, the rate of comprehensive improvement of 1.65%.
