905 Comments for Bethlehem Steel Mill

With my failing eyesight, I'm lucky I saw the three stars.

Amazing - I'd like to have that at home !!

Slag is lighter than the metal being refined thus it floats on the molten metal. It is oxidized metal and other garbage.

Its a bad word used to insult women in Britain autoguy.

This slag business was keeping me up at night. Oh the humanity! So a quick look reveals that the slag is tapped through a different port higher up in the furnace. There's the main tap hole and separate slag hole. https://secondaryscien...-iron-extraction.png

autoguy - T H A N K S!

In the slag dumping video I linked, they were banging hard on those wrecker-ball style to get the slag plugs to dump. Slag makes an excellent sand blast medium and can also be used for driveway roadbed. We should also use the word slag as often as possible. Better lives through slag.

How did I mess this one? :) I'll guess to haul them shafts that were on the rack. Interesting set of fan blades there. I'll guess those did the blowing.

YW, certainly. Temp was Fahrenheit. Temps of 1600 to 2000 degrees Celsius can be in these furnaces. One helluva wienie roast. The product is seen being channeled to the torpedoes, but I didn't see how they direct the slag to those cars with cones. This shows why the cone shape is needed.

@Motts- Thnx for the great link! Says 12 Tod engines are there and then lists engine 17? Yow! William Tod company made these giant steam engines for heavy industry. The monsters ran the rolling mills also. This many of them in one spot is incredible. One listed on factory invoices had a LP cylinder diameter of 6'. I think the largest could deliver up to 16,000 HP, with half that stored in the spinning 25' flywheels for load surges. Sadly, interest in preserving them is limited, and their size requires a lot of expensive resources to deal with them.

Tony C. : We LOVE the pictures, it IS fantastic. Thanks :)

YES Thank YOU SO MUCH, autoguy - of course have never seen anything like this - the thread had good info too - (and it is only 02.00 - so can se it again)............2.600 degrees, said - but C.or F.? Have no idea... C.?

Thanks Motts, BLUE! - LUCKY YOU to have been there.
And in the video (which saw twice at 04.00 in the morning, goodness !) a man just stands there LOOKING at the flywheel for a minute, all still
- I know would have done this also. Awesome + fantastic just the first words.....

Tony,

This happens in long exposures with light colors, they end up overexposed compared to the darker areas. It can be a cool effect like the star trails.

Hey, watch this
