FrugalRefiner said:I grew up in a city with a steel mill on the shore of Lake Erie. They loaded the slag onto tilting train cars, drove them out to an area high above a steep bank over a large water pond, and dumped them into the water. It was always an impressive sight as the red hot slag hit the water and sent up a huge glowing steam cloud that looked like a volcano exploding. The resulting material, known as popcorn slag, was sold as an aggregate used to make concrete.
I haven't thought about that for many years.

It's too fast to be a steam explosion, there is no pressurized vessel and to transfer so much heat to the water is impossible. I would say it's most probably the molten salt that is exploding and that it reminds me of Prince Rupert's drop where internal stresses create an explosion when the surface is damaged in one place.UncleBenBen said:Holy friggin bat snot!!! :shock: That's an impressive clip. Now, is that just purely a steam explosion, or are there other mechanics at play? It kind of looked like the slag itself exploded.
I bet it was fun cleaning up all that glass, and whatever filled his under shorts.

Untreated concrete can soak up a lot of moisture and, when molten slag hits it, an explosion can occur.
Can't be true, it would be a chemical perpetuum mobile.solar_plasma said:I don't know if it is true, but in the fire brigade education for leaders they told, that water will decompose to H2 and O2 if only the temperature is high enough and then the gasses will explode by reacting with each other again. The reason I think of that is, that the explosion looks quite as violent as an oxyhydrogen explosion when you watch the video by stopping step for step. I do not believe it is the slag alone that explodes, since it is jacketed in a gas bubble that is open at the top.
