【摘要】 针对某陶瓷厂煤气发生炉水夹套发生的鼓包事故,分别从宏观、微观形貌、化学成份、金相及相应的力学性能等方面进行系统的失效分析。结果表明:水夹套进水管堵塞,冷却功能丧失,导致水夹套内壁过热,且水夹套由于缺水,蒸汽压力增加,在蒸汽压力作用下,水夹套发生鼓包失效。最后根据失效原因,提出了相应的预防措施。更多还原

【Abstract】 For a factory gas furnace water jacket bulge accident,the system failure analysis were conducted from the macro and micro morphology,chemical composition,material metallographic and corresponding mechanical properties respectively.The results showed that:the water jacket inlet was blocked,the cooling function was lost,so the water jacket was overheated,and with the jacket lack of water,lead to the vapor pressure increase,under the affection of the vapor pressure,the water jacket was unstable.Finally,based on the cause of failure,put forward the appropriate preventive measures.更多还原
