[快,,,20點]好熱既野掂到凍水會唔會爆炸?

熱鋼熔液或熔渣遇水後, 水就立即蒸發, 化為蒸汽, 而且蒸發很激烈, 體積成千倍的增加, 由於所生成的水蒸汽被鋼液或熔渣所覆蓋, 水蒸汽不能自由排出, 就會產生巨大壓力, 把覆蓋的鋼液或熔渣崩開而發生爆炸。

因此在生產時, 爐坑和出鋼坑不應潮濕, 更不應有水, 在操作中不要用濕的吹氧管吹氧, 不要用濕的攪拌捅料和沾渣, 不要用濕的樣勺取樣。

你可以用少量其它物質如油, 蠟, 錫來試驗, 先加熱至熱熔漿, 然後加入一滴水, 後果自負。

鋼加熱直至熔化為熔液(熱鐵水)1200度以上

When a hot object touches cold water, there is rapid transfer of heat from the object to the water. After gaining heat, large amount water vapourizes quickly to become steam. The steam so formed pushes away the air surrounding it, thus producing an "explosion".
