I've always wondered... do the wheel lathes merely subtract metal, so a

I'm pretty sure they just skim material off. You couldn't add an alloy with
the right characteristics. It would also damage the wheel's heat treatment
if you poured liquid steel on to it.
Where are they going to get the liquid steel as they do not have an EAF
or a reheater nearby? Plus, it would indeed damage the existing wheel.
