摘要
在已测得钢坯内部几点从进炉到出炉随时间变化的温度曲线的情况下(例如黑匣子测温),根据传热导热原理以及正则化技术,建立了重建钢坯表面热流分布的数学模型,并且进一步重建钢坯内部温度的三维分布。该模型通过可行性验证,可望提供各火嘴燃料量和风量优化调整指导信息,确保工业炉安全和经济运行。
This paper described an mathematical model for rebuilding the surface heat flux of the billet steel in an industrial furnace, according to the heat transfer and conduct theory and the technique of regularization, in the case of having obtained some temperature curves, that changed follow the time between the billet steel being put in and pulled out of the furnace changed, of some inner points of the billet steel, and then rebuilding the distribution of the three-dimensional temperature of the billet steel. This model passed the validity check. It can be used to offer the guiding information of the fuel rate of the fire nozzles and input air optimization adjustment, to make sure the security and the economical efficiency of the industrial furnace during the running time.
