【摘要】 为了解决热轧卷板生产中出现的表面氧化铁皮缺陷,尤其是厚规格车轮钢,进行了热轧氧化铁皮形成机理的简单探讨,并以此为依据,进行了成分和轧制工艺的工业性试验。结果表明,降低Si含量,降低出炉温度和精轧入口温度,合适的卷取温度可以有效的控制氧化铁皮的性质和结构,从而减轻甚至抑制红锈氧化铁皮的生成。更多还原

【Abstract】 To solve the scale defects on the surface of hot strip, especially thick Wheel Steel, authors had discussed the mechanism of scale formation. According to the mechanism, the experiments of changing the component content and hot-rolling process had been tested. The results shows that the percentage of the scale decreases with the decrease of Si content, reheating temperature, FET(FM entry temperature) and appropriate coiling temperature.更多还原
