摘　　要：攀长钢连轧棒材线高压水除鳞系统由于生产品种钢结构的调整、坯料长度的变化,且高压水除鳞系统使用近15年,设备性能下降,已不能完全满足所有钢坯表面除鳞要求,红钢表面氧化皮去除不干净,轧制时压入严重影响了成品钢材的质量。通过研究计算和分析,为节约投资,部分改造升级原系统,设备基础、电机及控制系统全部利旧;泵阀、管路、除鳞箱、喷嘴进行优化升级,除鳞箱位置、辊道、翻钢剔废装置等相关设备进行局部改造。改造后高压水系统压力最高可以达到30MPa,满足连轧各类品种钢棒线材的生产,完全达到干净除去氧化皮的效果。Due to the adjustment of the steel structure of the production variety, the change of the billet length, and the use of the high-pressure water descaling system for nearly 15 years, the equipment performance of the high-pressure water descaling system in the continuous rolling bar line of Changcheng Special Steel Co., Ltd.has declined, which can no longer fully meet the requirements for descaling of all steel billet surfaces. The oxide scale on the surface of red steel is not removed cleanly, and the pressing during rolling has seriously affected the quality of finished steel products. Through research, calculation and analysis, in order to save investment, part of the original system is upgraded, and the equipment foundation, motor and control system are all used;The pump valve,pipeline, descaling box and nozzle are optimized and upgraded, and the position of descaling box, roller table, steel turnover and waste removal device and other related equipment are partially modified. After the transformation, the maximum pressure of the high-pressure water system can reach 30MPa, which can meet the requirements of continuous rolling of all kinds of steel bars and wires, and completely achieve the effect of clean removal of oxide scales.
