前混合磨料水射流切割钢板和混凝土的实验研究

Eeperimental Study on the Cutting of Steel and Concrete with the Pre-mixed Abrasive Jet

探讨前混合磨料水射流切割不同材料的影响因素 ,找出它们之间的关系 ,为合理预测切割深度和实际应用提供参考。试验对比研究了前混合磨料射流参数 (压力、靶距、磨料浓度和横移速度 )对切割钢板、混凝土的深度与宽度的影响 ,取得了一些有意义的结论 ,即前混合磨料切割钢板、混凝土时 ,射流参数对切割影响基本一致 ,所不同的是影响程度不一致。该研究对前混合磨料射流切割脆性材料和塑性材料具有一定的指导意义。

This paper discussed factors that affect the cutting of materials with pre-mixed abrasive jet (PREMAJet), and relationships between the parameters and the results of cutting. Based on experiments, meaningful results have been derived that reveal the relationships between PREMAJet parameters and the cutting depth and width of steel plate and concrete The results show that when cutting steel plate and concrete with the PREMAJet, the effects of parameters appear to have little difference, affecting only in degrees. The study is of help in cutting brittle and ductile materials with PREMAJet
