摘　　要：储罐底部往往面临比较恶劣的腐蚀环境,底板的腐蚀常常比较严重。本论文研究了典型储罐底板材料Q235B在模拟储罐底部介质环境中的电化学腐蚀行为,分析是否含硫、氯离子浓度、矿化度等不同因素对腐蚀速率的影响,并分析了影响规律。鉴于多种因素影响条件下腐蚀规律的复杂性,采用BP神经网络对储罐底板腐蚀速率进行了预测研究。论文所做的工作为储油罐腐蚀状态评估及剩余寿命预测提供了依据。Corrosion was the most important reason for tank failures. Based on weight loss method, SEM and EDS technology, the electrochemical corrosion behavior was studied. Besides, influence factors on corrosion behavior and rules were analyzed on different conditions of sulfur and Cl - concentration, and degree of mineralization. In wiew of the complexity of corrosion law under a variety of influencing factors analysis of weld corrosion of oil tank floor was carried out by BP neural network. The work provided a solid foundation for the assessment and management of oil tank.
