摘要 采用标准kε-紊流模型,对连续退火炉中快冷段局部带钢的二维非稳态温度场进行CFD模拟,模拟与实际结果吻合较好。研究结果表明:从温度均匀性和冷却速度来看,当氢气体积分数为30%时,冷却效果最佳;控制最优的冷却速度可以通过控制带钢初始温度、带钢与风箱间距和冷却气体喷出速度、冷却介质的含量等参数来实现。 The unsteady standard k-ε turbulence model was adopted to simulate the continuous annealing furnace steel cooling process, the simulation agrees the experimental results very well. The investigation shows that the temperature uniformity and cooling rate are optimized when the hydrogen concentration is 30%; by controlling the strip initial temperature, bellows-strip spacing, cooling media components ratio and jet rate of the cooling gas, controlled optimized cooling rate can be obtained.
