深井铸造熔融铝泄漏遇水爆炸破坏影响研究

Study on damage influence of explosion caused by molten aluminum leakage in deep well casting with water

为深入理解熔融铝液遇水爆炸的机制,量化爆炸引发的破坏影响,从物理蒸汽爆炸和化学氧化反应爆炸引起的超压破坏,以及爆炸碎片飞行距离3个方面分别建立数据模型和计算分析,详细阐述不同计算量的熔融铝液遇水反应爆炸引发的超压破坏所造成的人员和建筑物损害,讨论不同抛射角度下爆炸碎片飞出距离所产生的影响范围,从而更加直观的认识爆炸带来的破坏影响。研究结果表明:熔融铝液遇水发生爆炸事故中,破坏性最大的是化学爆炸,其次是物理爆炸,最后是由爆炸引起的碎片抛射;且在相同的抛射初速度下,碎片以30°的抛射角飞出的水平距离最远。

In order to deeply understand the mechanism of the explosion of molten aluminum liquid in contact with water and quantify the damage influence caused by the explosion,data models and calculation analysis were established in terms of the overpressure damage caused by physical steam explosion and chemical oxidation reaction explosion and the flight distance of explosion fragments.The damage to personnel and buildings caused by the overpressure damage due to the explosion of molten aluminum liquid in contact with water under different calculated amounts was described in detail,and the influence range related to the flight distance of explosion fragments under different ejection angles was discussed,so as to more intuitively understand the damage influence caused by the explosion.The results show that the chemical explosion is the most destructive,followed by the physical explosion and the fragment ejection caused by the explosion during the explosion of molten aluminum in contact with water.At the same initial velocity of the ejection,the farthest horizontal distance of the fragment is achieved at the ejection angle of 30°.
