摘　　要：在试验研究和理论分析的基础上,本文定义了一个无固次角度系数,并用于定量反映塑性材料的冲蚀磨损率随飞灰冲刷角度变化的规律,同时建立了无因次角度系数计算式,可供工程实际应用.Based on the experimental investigation and theoretical analysis, a dimensionless coefficient of ash impact angle is defined, and its calculation formulae are set up. The relationship between coal-fired boiler metal erosion rate and fly ash impact angle has been found through experiments of impacting ductile metals. The results can be applied to engineering.
