摘　　要：除鳞作为板轧钢工艺中不可缺少的重要工艺,提高高压水除鳞系统稳定性有助于提高板坯生产质量。文章以高压水除鳞系统故障频发分析及应对措施进行讨论,对高压水除鳞系统的组成及工作原理进行分析后,对高压水除鳞系统故障频发进行了分析,发现主要存在高压除鳞管路漏水、预充水系统故障、系统跑水跑气、高压水系统压力波动较大、除鳞阀故障、高压水系统高压离心泵等问题。针对上述问题,文章提出了具体应对措施后,提出高压水除鳞系统故障应对保障机制,应减少管网法兰连接,增加管夹,加装防震垫,对轧机除鳞下集管进水管进行改造,提高水质的同时,加强设备定期的检查、维护。Descaling is an essential process in the plate rolling steel production,and improving the stability of the high-pressure water descaling system contributes to enhancing the quality of slab production.This article discusses the frequent failures of the high-pressure water descaling system and corresponding countermeasures.After analyzing the composition and working principle of the high-pressure water descaling system,the article identifies several issues,including water leakage in the high-pressure descaling pipeline,failures in the pre-charging water system,water and air leakage in the system,significant pressure fluctuations in the high-pressure water system,faults in the descaling valve,and problems with the high-pressure water system's high-pressure plunger pump.In response to these issues,the article proposes specific countermeasures and suggests establishing a failure response assurance mechanism for the high-pressure water descaling system.Recommendations include reducing flange connections in the pipeline network,increasing pipe clamps,adding shock-absorbing pads,modifying the water inlet pipe for the descaling manifold of the rolling mill,improving water quality,and strengthening regular inspection and maintenance of the equipment.
