摘　　要：基于硅酸盐制品蒸压釜的结构及生产工艺,研究其失效模式,蒸压釜主要失效形式为快开门安全联锁装置失效、釜底电化学腐蚀、釜齿根部疲劳开裂、筒体应力腐蚀开裂。在此基础上确定其定期检验的方案,明确重点检验区域,在保证检验质量前提下减少检验项目,安全评定其失效现状,提出此类压力容器安全运行及检验的改进建议,提高安全监管的科学性和有效性,避免事故的发生并确保设备安全、长周期运行。Based on silicate product still kettle＇s structure and production process, its failure model was studied in this paper. Still kettle＇s main failure forms can be expressed as four kinds, quickly open the door safety interlocking device＇s failure, the bottom of kettle＇s electrochemical corrosion, the root of kettle＇s fatigue cracking and barrel＇s stress corrosion cracking. The scheme of periodic inspection was determined on this basis, then the key inspection area was clear; the test project was reduced under the premise that ensure the testing quality, the failure simulation was evaluated safely, the recommendations for improvement of safe operation and inspection of pressure vessels were put forward, the safety and effectiveness of security control was raised. Therefore, we can avoid the happen of accident and ensure the equipment safety running for a long period of time.
