摘要
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.关键词
