| Abstract: | Gas jet cooling is the main way of steel rapid cooling in the vertical continuous annealing furnace.Calculation of strip temperature field distribution during the cooling process has the important guiding significance for the improvement of the strip continuous annealing process.Using CFD simulation software to simulate the cooling process,get the distribution of the strip surface heat transfer coefficient.Using finite difference method gets on numerical simulation for strip temperature field distribution.This paper also studied the effect of initial strip temperature on strip temperature field distribution during the cooling process. |
