以二维非稳态凝固传热数学模型为理论基础,结合铸坯在连铸过程中的冷却规律,建立了连铸机凝固传热有限差分数学模型。利用Visual Basic 6.0语言编程,开发出了模拟凝固传热的通用仿真软件,并利用SCIT-1M红外测温仪采集铸坯表面温度,对结果进行验证,误差范围在0.4%~1.1%之间,说明仿真结果真实可靠。 Based on the two-dimensional unsteady solidification heat transfer mathematical model, combined with the cooling rule of slab in continuous casting process, finite difference mathematical model of solidification heat transfer in continuous casting machine was established. Visual Basic 6.0 language programming was used to develop a general simulation software to simulate solidification and heat transfer. SCIT-1M infrared thermometer was used to collect the surface temperature of slab, and the results were verified with error range of 0.4% -1.1% Simulation results show that true and reliable.
