摘要

以泡沫镍板为研究对象，采用实验与数值分析方法，研究了泡沫镍板在冷却过程的基本特性。实验结果表明，在泡沫镍板生产线正常运行期间，整个冷却过程可视为稳态过程，镍板各部分温度基本保持不变。较大温度梯度主要集中在两处，第一是还原性气体入口处，第二是高温水冷段的前半段。数值分析表明，改变镍板的运动速度时，第一温度梯度随着镍板运动速度的增加而增加，第二温度梯度随着速度的增加而减少，二者出现的位置也相应变化；改变高温水冷段水温时，水温升高引起第二温度梯度减小，对其他位置的温度场影响较小。

Abstract

In this paper

the cooling characteristics of foam nickel plate in the cooling section of the production line are studied by means of experiment and numerical analyses. Experimental results show that during the normal operation progress

the temperature of the entire foam nickel plate remains basically unchanged. The maximum temperature gradients are located at two positions

one is the entrance of the reducing gas and the other is in the first half of the high temperature water cooling section. If changing the movement velocity of the nickel plate

the first temperature gradient becomes larger together with the larger movement velocity of the nickel plate and the second temperature gradient decreases with the increase of movement velocity

and the corresponding positions are also changed. If changing the temperature of the high temperature water

the higher the water temperature

the smaller the temperature gradient in the second place

and the other temperature distribution is less affected.
