摘要
选取辊式淬火机为研究对象,通过分析钢板冷却过程传热机理,建立了钢板热传导数学模型。采用外节点法和有限差分方法分别对计算区域和控制方程离散化处理,运用VB.NET语言编写程序,对钢板淬火冷却过程温度场进行仿真研究。结果表明,本文所建立的淬火过程热传导数学模型可以作为淬火机二级控制系统的基础,进行过程控制系统的开发。
Mathematical model for heat conduction of steel plate was built on roller-type quenching machine based on analyzing heat transfer theory of steel plate quenching process.The computational domain and governing equation were scattered by the outside node method and finite difference method,respectively.Simulation on temperature field of steel plate during quenching process was done by programming using VB net language.The results show that the quenching machine secondary control system can be built based on the quenching process mathematical model of steel plate heat conduction.
