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.

研究结果表明：在加热过程中生成的氧化层增大了换热热阻，使钢坯的加热速度减小；钢坯氧化烧损量随加热速度的增大而减小；当达到同一特定的均热温度时，钢坯氧化烧损量随空气消耗系数的增大近似呈线性递增；当空气消耗系数一定时，钢坯氧化烧损量随均热温度的提高而急剧增加；数值计算结果与实验结果变化趋势一致，并在CSP均热温度范围内较吻合。
