中文摘要: 冲刷速度是影响飞灰冲蚀磨损的主要因素,速度对冲蚀磨损的影响与温度有着很大的关系.研究了12Cr1MoV合金钢在不同温度时冲刷速度对磨损率的影响,并且用速度指数n表征.试验数据结果表明:在热态试验中(250~550 ℃),飞灰磨损速度指数为1.006 27~0.827 52;而在常温态试验中,速度指数达到2.95,基本规律为飞灰磨损速度指数随温度的升高而降低,且常温态的相对磨损率明显大于热态时的相对磨损率.
Abstract:The velocity is the major effective factor for the flying-ash erosion,and its influence has close relation with the temperature condition.The influence of particle velocity for flying-ash erosion of 12Cr1MoV steel is studied on the experiment,in different temperature conditions,and is characterized by velocity index.The analysis on the data of the flying-ash erosion tests shows that the velocity index for flying-ash erosion varies from 1.006 27 to 0.827 52 in hot conditions from 250 ℃ to 550 ℃,and 2.95 at normal atmosphere temperature.So the basic rule is that the velocity index for flying-ash erosion varies as the inverse temperature and the relative erosion-wear is significantly higher at normal atmosphere temperature than that in hot conditions.
