摘　　要：通过氧化模拟实验,观测了试样加热到不同温度时的氧化铁皮起皮情况,绘制了氧化动力学曲线,研究了高温下钢板在不同硅、磷质量分数时对氧化铁皮生长速率的影响。实验结果表明,在1100℃且经30 s氧化后,除含硅较低的钢种C外,其它钢种的表面都出现了独立的小气泡;经120s氧化后各钢种的表面都完全形成了氧化膜。在较高温度(>1000℃)时增硅会促进氧化铁皮的起皮;w(P)≤0.005%时,无论在任何温度下都抑制了氧化铁皮起皮。The blistering of oxide scale at different temperature during heating was observed, the kinetics curve of the specimens after oxidation was plotted, the effects of different Si, P content on oxidation rate of scales during hot rolling strip were studied by experiment of oxidation simulating. The result shows that the small absolute blister appeared on the surface of the steels except steel C after oxidation at 1 100℃ for 30 s, the oxide scale formed uniformly on the surface of all steels at 1 100 ℃ for 120 s. The addition of Si content at temperature higher than 1000 ℃ promoted tile scale blistering. When w（P）≤0. 005 %, the scale blistering was suppressed at any temperature.
