摘　　要：目的对合金盘条高压磨料水射流除鳞系统进行优化。方法建立一条合金盘条高压磨料水射流除鳞系统实验装置,研究材质、工作压力、喷嘴数量、移动速度、磨料浓度、靶距等参数对除鳞效果的影响;应用图像处理技术对除鳞效果量化为除净率并加以分析,采用MATLAB软件对系统压力、喷嘴数、移动速度、磨料浓度及靶距对除鳞效果进行拟合分析。结果设计了年产5000吨合金盘条高压磨料水射流除鳞系统,参数为:额定压力45 MPa、额定流量10 m3/h、最大除鳞速度40 m/min、磨料质量分数35%、靶距20 mm、喷嘴12个。结论高压磨料水射流除鳞系统能满足合金盘条除鳞的设计要求,应用前景广阔。Objective To optimize the high-pressure water jet system for alloy rod. Methods A high-pressure water jet descaling system test device for metal rod was established,and the effects of material,working pressure,nozzle number,speed,abrasive concentration,and target distance on descaling result were studied. Image processing technology was adopted for the quantitative analysis of descaling effect,and the descaling effect was quantized to a precise representation of net descaling rate. The effects of system pressure,nozzle number,movement speed,abrasive concentration and target distance on descaling were fitted and analyzed by MATLAB software. Results The production line of 5000 t / a high-pressure water jet descaling system for alloy rod was designed,with the parameters as follows： rated pressure 45 MPa,rated flow 10 m^3/ h,maximum speed descaling 40 m / min,abrasive concentration 35%,target distance 20 mm,amount of nozzles 12. Conclusion The high-pressure water jet descaling system could meet the descaling design requirements of alloy wire rod,with broad application prospects.
