The results show that the rate of heating decreases due to the growth of oxidation layer in soaking process when the thermal resistance between gas and slab increases. The quantity of loss of iron scale increases with the increase of the coefficient of air consumption under the condition of certain soaking temperature. When the coefficient of air consumption is certain, the quantity of loss of iron scale increases with the increase of soaking temperature rapidly. The results of numerical simulation is consistent with experimental ones, and the error is very small within the range of soaking temperature in CSP line.
