As a kid we would go and watch the slag dumping at night in Northern Ontario, it was really cool to see. It was just like watching a volcano erupt, without all the screaming.
Very informative video. I was expecting a video just showing machines...the in-depth information was very interesting!
I remember back in the 1970s my grand parents lived in baden Pennsylvania across the river from J and L steel aliquippa they would dump the slag at night and it would light up the night sky like day light and every morning there was residue or ash on the cars it's weird the things you remember about childhood
I believe the second clip was actually coke not slag. I’ve worked in steel production for 28 years and took many tours of steel plants and the most impressive was Nucor steel.
Slag is always on top of the crucible so why don’t they just empty the crucibles from the bottom first ? Let the slag stay behind and then flip it out? Never understood this …
There are factories extracting metal from metallurgy waste - from slag accumulated over 100 years. They don't need iron ore and ore mining or transportation costs. They have something better than iron ore - slag. The slag contains up to 60% of the metal and it is already compactly assembled and does not require transportation and extraction costs.
