摘    要：为精确跟踪某公司新建辊底式高温固溶炉内钢板温度,详细研究了明火炉内炉气温度、钢板内部导热和炉内传热机制,建立了考虑炉段间耦合的炉气温度数学模型和钢板温度跟踪模型,采用FDM法对数学模型离散化,结合TDMA数值方法进行求解。在线应用结果表明所建立的数学模型简单、可靠,为钢板加热质量的控制提供了科学依据,提高了出炉温度命中率。

Abstract: In order to obtain the plate temperature of one company′s new high-temperature roller hearth furnace accurately,the mathematical models of the furnace gas temperature and heat transfer in the plate internal and roller hearth furnace were studied and established.On the basis of detailed analysis,the plate temperature tracking mathematical model in furnace was built,which was solved by FDM and TDMA methods.The applications show that the plate temperature tracking model is simple and reliable,can provide a scientific basis for plates′ quality control in the heating process and improve tapping temperature hit rate.
