I thought the machine was pulling out a lightsaber...!

It's okay, that guy's getting the hose.

Reminds me of a bout of cystitis I had once.

I wonder how they cleaned it up once the metal cooled down

Umm. Move away from the facemelting object?

Seriously, why is there no running for their lives happening?

So that's how they make lightsabers.

Careful Siftbot, you'll go blind.

^Quality.

Play-Doh just got awesomer

It came.

One step closer to Ghostbusters!

I used to work with something similar to this and after a while one gets used to how molten metal works and knows what to expect. Explosions due to steam/pressure were what we at my work were wary of. A few metric tons of molten metal at the wrong place was not unexpected but very inconvenient (and made everything uncomfortably hot).

And the guy who brings the hose probably uses it to keep cables and other stuff from burning up due to the heat. With such small quantities of metal as that was, it will lose most of the heat quite quickly (unless one touches it of course) meaning that likely only the stuff it touches directly will be damaged.

So how does it work?? as metal heats it emits infrared, which we sense as heat. As it keeps getting hotter, the emissions move into the visible light? If you keep heating does it move into still faster light like UV?

Basically, the steel rolling process starts with a huge slab of steel about 20-30 feet long, which is heated up to a few hundred degrees in a giant oven. Once it exits the oven it's sent on a conveyor through a series of rollers with smaller and smaller gaps between them, going from around 200mm tall to 2mm tall, o More..ver a distance of a few kilometers. As a side effect from this, the slab gets extremely long (larger plants can end up with sheets over 200m long), and moves extremely quickly.

The reason it has to move so quickly is that the compression elongates it, so the exiting material has to be moving faster than the entering material, or you'll get a nasty 400 degree, 20 ton traffic jam.

The conveyor it travels on is essentially a series of rollers spaced around 1-2 feet apart, and when it's rocketing along like in the video, the leading end will bounce slightly as it hits each roller. On very rare occasions that leading end will bounce high enough to catch on something, or even curl over of its own accord, causing what you see in the video, where it looks like the sheet has hit the front end of the roller.

Yeah, most materials behave like black bodies and the wavelength of peak radiance increases with temperature ( http://en.wikipedia.org/wiki/Black_body ).

Humans can easily feel the heat from infrared, visible, or ultraviolet radiation of high enough intensity. Actually, I assume we can sense the heat from any type of radiation. Radio (in a microwave), x-ray, or gamma ray. But obviously you don't ever want absorb intense radiation at those wavelengths.
