摘要/Abstract

摘要： 为揭示工业中蒸汽爆炸的形成机制,设计半封闭条件下大质量熔融铝液遇水自触发爆炸模拟装置,应用高速摄像仪记录爆炸形成过程,分析铝液与水的相对质量、温度、容器材质及金属氧化物等因素对爆炸的影响。试验结果表明:半封闭条件下熔融铝液遇水爆炸反应存在较明显的爆炸临界条件和温度极限;润湿性较高的碳钢材质更容易触发爆炸反应;与非金属氧化物相比,水溶性高的金属氧化物对爆炸反应起明显的促进作用。

关键词: 蒸汽爆炸, 熔融铝液, 温度极限, 润湿性, 金属氧化物

Abstract: In order to investigate the mechanism of steam explosion in industry,an simulated experimental system for spontaneous explosion of massive molten aluminum and water in semi-confined space was designed.A high speed digital visualization system was employed to obtain the information on the explosive interaction under different conditions.The effects of the relative mass,the temperature,the vessel material and metal oxide on explosion were studied.The results show that the critical explosive condition and temperature have been obtained for explosion of massive molten aluminum and water in semi-confined space,that carbon steel with high wettability promotes base-triggered explosion,and the metal oxide with high water solubility also promotes explosive interaction,compared to non-metal oxide.

Key words: steam explosion, molten aluminum, temperature limit, wettability, metal oxide
