【摘要】 利用商业软件 Fluent 对双室式加热炉内热过程进行模拟。通过改变热负荷、燃烧器布置方式、燃烧器结构尺寸等参数对双室式加热炉内的辐射传热、对流换热以及钢坯内部的导热等非稳态耦合过程进行了数值分析。通过对结果的比较分析,确定了适合于该室式炉燃烧器的结构参数和操作参数。为更均匀有效的加热钢坯,提高双室式炉的热效率提供了理论依据。更多还原

【Abstract】 Numerical simulations of transient thermal process in the dual chamber reheating furnace have been made using the commercial software Fluent.Radiation,convection and conduction are coupled in the simulation.Some main parameters(gas fuel consumption,burner arrangement and structure)are taken into account.From the results of present simulations,the reasonable operating and structure parameters corresponding to the more uniform temperature of the being heated steel billet and high thermal efficiency of the furnace are suggested.The models and numerical method may provide theoretical foundation for industrial production.更多还原
