日本岩乎县炼铁厂在一次将铁水注入铸模时,因铁水罐倾斜,铁水流入积存在低凹地面的雨水中而发生的爆炸事故,当场死亡3人,伤5人,并认定为水蒸气爆炸。1989年8月6日,长城特殊钢公司第四钢厂废钢车间,因过早向钢渣注水冷却而发生爆炸,也属于水蒸气爆炸事故。水并不属爆炸类物质,何以能引起爆炸事故?我们知道,当水由液相变为气相(水蒸气)时,在温度为100℃的情况下,其体积约可增大1700倍;如果生成的水蒸气温度上升至500℃,则体积可增大3500倍。由于体积急剧膨胀,压力迅速上升,便会发生爆
Japan’s Iwafu Iron Mills fired 3 tons of molten iron into the mold at the scene of an explosion that caused the molten iron to flow into the rainwater trapped in the low-lying ground. Three people were killed and 5 were injured. They were identified as water vapor explosion. August 6, 1989, the Great Wall Special Steel Company fourth steel mill scrap shop, due to premature steel slag cooling and explosion, also belong to the steam explosion. Water is not an explosive substance, so why it can cause an explosion? We know that when the water is changed from liquid to gas (water vapor), its volume can increase by 1700 times at a temperature of 100 ° C. If The resulting steam temperature rises to 500 ℃, the volume can increase 3500 times. Due to the rapid expansion of the volume, the pressure rises rapidly, it will burst
