Re: Worker Jumps into a Steel Melting Furnace
the internet says... Molten steel is somewhere between 2600–2800ºF, depending on admixtures. Lava is cooler, between 540ºF on the low end, up to 2120ºF for magma lakes. Keep in mind that there's a big difference in the conductivity of materials. You can stick your hand in a pizza oven without the air turning it into a charcoal briquette, but a second of contact with the metal sides — which are nearly the same temperature — will give you a second-degree burn. "...Some people in Pompeii died of "thermal shock" (i.e.: getting cooked alive) at peak temperatures of only about 500ºF. Granted, the case is a little different since the particulate ash was the medium of exposure, and in the case of falling onto molten steel, the Leidenfrost effect might protect the body for a second or so. A modern crematorium operates at 1600–1800ºF, which is enough to reduce a body to ash and bone fragments. (I know this in intimate detail, having participated in the rites for two Japanese funerals so far. Everyone in attendance picks bones out of the ashes and places them in a container. There aren't many bone fragments left bigger than a finger. The bone at the front of the skull seems to remain intact the best; a piece about the size of the palm of your hand remains.) Cremation takes about 1.5–2 hours for this, but keep in mind the properties of thermal transfer I mentioned earlier and realize that a furnace does this with an air temperature about 1000ºF lower than molten steel. You probably wouldn't feel anything since even the air would be hot enough to sear your nerve endings before you actually hit the steel. You might, just might, have enough time to attempt to scream before your lungs explode and your corpse starts burning. Not exactly a pleasant way to die, but relatively fast..." |

Re: Worker Jumps into a Steel Melting Furnace
He likely felt pain for at least a couple seconds or so. I've never tried it with melted steal. But you can dip your finger into melted lead, and pull it out without getting burned. As long as you do it quickly. I'm guessing this guy would be covered in sweat being in a room with that much heat. Which would be a thin layer of moisture that may have protected him for a quick second. |

Re: Worker Jumps into a Steel Melting Furnace
He misheard, he thought it was Painless Steel, turned out it was Stainless Steel.  |
