摘　　要：为了减少酸洗工艺在去除镍合金轧制盘元表面氧化皮(除鳞)时所产生的工艺金属损失及污染排放,依据高压磨料水射流除鳞工艺特点,建立完整的轧制镍合金除鳞工艺实验替代酸洗工艺装置,设定盘条收线速度、水压、磨料浓度等除鳞工艺参数,针对两种不同工艺生产过程中的镍合金盘元进行表面氧化皮去除,进行除鳞工艺前后的镍合金盘条抗拉强度、伸长率以及电子探针(EPMA)检测的表面形貌对比分析。结果表明:经过除鳞工艺前后对比,金属损耗基本低于0.5%;镍合金盘条抗拉强度变化不明显,强度相当;伸长率基本保持不变,满足标准要求;电子探针检测(EPMA)显示不同盘条除鳞后表明氧化皮基本去除。所建立的高压磨料水射流除鳞工艺装置,能够达到除鳞效果,证实该高压磨料水射流除鳞工艺可行可靠。In order to reduce the metal loss and pollution emission caused by pickling process in removing the oxide skin(descaling)on the surface of nickel alloy rolling disc elements.According to the characteristics of high pressure abrasive water jet descaling process,a complete experimental replacement pickling process device for rolling nickel alloy descaling process was established.The descaling process parameters such as wire winding speed,water pressure and abrasive concentration were set.The tensile strength,elongation and surface morphology of nickel alloy rod before and after descaling process were compared and analyzed.The experimental results show that the metal loss is less than 0.5%after the descaling process.The tensile strength of nickel alloy rod does not change obviously,and the strength is similar.The elongation is basically unchanged,which meets the standard requirements.Electron probe detection(EPMA)shows that the oxide skin is basically removed after different rod descaling.The established high pressure abrasive water jet descaling process device can achieve descaling effect,which proves that high pressure abrasive water jet descaling process is feasible and reliable.
