摘要
运用有限元法对微水节能热风阀阀板在稳态下的温度场进行了传热学分析,并用有限元软件ANSYS计算出了阀板在稳态工作状态下的温度场分布,阀门在完全开启状态时,阀板外圈温度最高,温差最大,易引起阀板外圈变形;阀门在关闭状态时,阀板与耐火材料交界处的最高温度为205℃左右,并且阀板芯温度随着耐火材料的热导率的增大而升高.
In this paper, the stable state temperature field of the valve plate of hot blast valve with minimum cooling is analyzed by making use the finite element method. And the stable state temperature distribution is calculated by using ANSYS. When the valve is fully open, the temperature is the highest and the temperature difference is also the biggest at the outer of the valve plate, and most easily to cause the outer of the valve distortion. When the valve is closed, the maximum temperature at the junction of the valve plate and refractory material is about 205 ℃ , and the temperature of the valve plate core increases with the increase of the heat conductivity of refractory material.
