介绍了磨料水射流圆钢表面的除鳞装置,研究了磨料浓度对圆钢表面除鳞效果的影响,实验中选用适当的磨料以不同的浓度分别与高压水射流混合,通过对圆钢表面除鳞效果的比较,证明80目石榴石浓度50%的磨料水射流对圆钢表面的除鳞效果最佳,数值计算结果与实验基本一致。
The descaling device on the surface of round bar of abrasive water jet was introduced. The effect of abrasive concentration on the surface descaling of round bar steel was studied. In the experiment, proper abrasive was mixed with high pressure water jet at different concentrations respectively. The comparison of scale effect shows that the descaling effect of abrasive water jet with 50% garnet concentration of 80 mesh on the surface of round bar is the best. The numerical results are in good agreement with the experiment.
