You don't target cheap steel market with this, you go after VAR, and ESR steel.

> Among other benefits, you're now only heating the material once instead of 2-3 times, and as a result, you actually consume less total energy in this process even though you have to reach a higher temperature in the single heating.

So, that's why MOE wasn't around before 2013.

MOE wasn't, but colocating blast furnaces with steel converters is a very old idea.
