摘要:
采用光学显微镜、扫描电镜和能谱仪等分析手段，分析了SPHC热轧带钢氧化铁皮厚度和结构。此外，通过实验研究了酸洗参数以及抑制剂对SPHC热轧带钢表面质量的影响及其酸洗机理。结果表明：酸洗温度和再生酸浓度越高，越容易快速去除氧化铁皮，同时也更容易导致过酸洗现象。在80 ℃，207.89 g/L的再生酸溶液中加入0.5%的酸洗抑制剂，其酸洗腐蚀速率从5.00%下降至0.12%，缓释率高达97.51%，显著降低了试样的铁损，提高了带钢的表面质量。
Abstract:
The thickness and structure of SPHC hot-rolled scale were analyzed by means of optical microscope, scanning electron microscope and energy spectrometer. In addition, through experimenting, the impact of the pickling parameters and inhibitors on the surface quality of the SPHC hot -rolled steel surface and pickling mechanism were studied. The results show that the higher the acidity and regenerative acid concentration, the easier it is to remove the iron oxide skin quickly, and it is also more likely to lead to the phenomenon of overly. At 80 °C, 0.5 %of the pickled inhibitors were added to the regenerative acid solution of 207.89 g/L. The acid washing rate decreased from 5.00 %to 0.12%, and the slow release rate was as high as 97.51 %, which significantly reduced the sample iron damage and improved the surface quality of the steel
