To explore the influence of magnetized water on rheological properties of paste slurry pipeline conveying,an indoor experiment was carried out.On the basis of self-made L-inclined tube test device,the physical simulation test of gravity flow of paste slurry under different magnetizing conditions was carried out by orthogonal experimental design.The experimental results were optimized and screened in the end.The results show that the rheological properties of paste slurry can be effectively improved by magnetized water.Besides,magnetized water can reduce yield stress and plastic viscosity of slurry with suitable magnetization conditions,which can improve the reliability of slurry pipeline transportation at the same time.Furthermore,contrasting with blank group,when the magnetic induction being 200~300 mT,magnetized time being 15~25 min and cycling rate being 0.5~1.5 L/s,the friction loss of paste slurry is the smallest,the yield stress and plastic viscosity are reduced by 8%~20% and 12%~35% respectively.
