Nowadays, many industries are searching new and effective
substitutes for traditional energy resources. Heavy industries are not
excluded. In order to use the most of the limited resources, they look
for new techniques and new energy management systems which are
efficient in energy consumption. Studying in saving energy for
reheating furnace and in approving operation conditions may help
heavy industries to reduce costs and to enhance quality of products.
¡@¡@Inevitably, the inner compositions of alloy ingots are not
uniform during continuous casting. To solve this problem, we
usually do heat treatment on alloy ingots before casting. Besides, to
ensure the quality and stability of alloy ingots in heat treatment, we
need an effective tool to monitor the temperature distribution on ally
ingots. Moreover, the precise control over energy consumption can
improve the efficiency of reheating furnace and can reduce costs.
¡@¡@This study focuses on alloy ingots. We simulate heat transfer by
numerical methods and construct the integrated software to simulate
the characteristics of reheating furnace in batch type operation.
Analyses in the temperature distribution and energy consumption of
alloy ingots in reheating process are also included. Besides, we
choose some parameters, which might affect the energy consumption
and try to find the best level parameter composition in reheating
furnace analysis by Taguchi method. Some results are shown below:
¡]1¡^When temperature rising process starts, our model provides
¡@ ¡@reasonable and exact prediction in one or two hours.
¡]2¡^Reheating furnace treatment ability is the most important
¡@ ¡@control factor (out of eight) in this study.
¡]3¡^We can reduce around 3% of the consumption with the
¡@ ¡@parameters obtained by Taguchi method.
¡]4¡^The soaking degrees are all below 0.01¢J after heat treatment
¡@ ¡@on alloy ingots.
¡]5¡^We change the temperature rising rate to simulate the situation
¡@ ¡@of heated alloy ingots. We find that the higher temperature
¡@ ¡@rising rate is, the more significant temperature difference
¡@ ¡@inside alloy ingots is. On the other hand, the lower rate would
¡@ ¡@increase the soaking degree.
