The weak reduction atmosphere, which causes different beginning oxidation temperatures, is often used in the forepart of an industrial furnace to reduce the formation of oxide scale. The present study analyzed the oxidation behavior of a dual-phase Si-containing steel at different beginning oxidation temperatures based on the industrial reheating process. The results indicate that the adoption of the weak reduction atmosphere before the intense oxidation temperature had no profound effects on the oxidation mass gain and the distribution of Fe2SiO4. Therefore, the end temperature of the weak reduction atmosphere must be higher than the intense oxidation temperature. Moreover, the oxidation mass gain and the penetration depth of Fe2SiO4 gradually decreased with the increase in beginning oxidation temperature when the heating temperature was higher than the intense oxidation temperature of the steel. In addition, the oxidation rate remained constant when the heating temperature was higher than the intense oxidation temperature of the steel; thus, oxidation mass gain followed a linear law with time. Furthermore, voids that appeared in oxide scales were attributed to the formation of Fe2SiO4/FeO and volatile products.

双相含硅钢在不同起始氧化温度下的氧化行为研究

引起不同起始氧化温度的弱还原气氛通常在工业炉的前部使用,以减少氧化皮的形成。本研究基于工业再加热过程,分析了双相含硅钢在不同起始氧化温度下的氧化行为。结果表明,在强氧化温度之前采用弱还原气氛对氧化质量的增加和Fe 2 SiO 4的分布没有明显的影响。因此,弱还原气氛的终止温度必须高于强氧化温度。此外,Fe 2 SiO 4的氧化质量增加和穿透深度当加热温度高于钢的强氧化温度时,随着开始氧化温度的升高而逐渐降低。另外,当加热温度高于钢的强氧化温度时,氧化速率保持恒定。因此,氧化质量的增加遵循时间的线性规律。此外,以氧化皮出现的空隙归因于Fe 2 SiO 4 / FeO和挥发性产物的形成。
