Foundry worker puts wet scrap metal in furnace full video
"This is what is classified as a Force 2 explosion, meaning that it threw the molten aluminum at least 10-20 ft and "lifted" up a substantial part of the molten. The operator, despite the incident is EXTREMELY lucky. A Force 1 is a small "pop" or splatter. A Force 3 would've have leveled this building and likely killed all in the video.
The differences between the explosions has NOTHING to do with the amount of scrap being charged or the amount of moisture/water in the scrap. With Force 1 or 2, water gets trapped under the molten, superheats, and expands over 3000 times it's size in an instant, creating a molten explosion. With a Force 3, enough molten aluminum is tossed in the air that it oxidizes with the air, stripping away the oxygen from the moisture in the air, leaving only hydrogen in gas form, which then ignites."
