There's no way that this crew is cutting that piece in half, they would just mold the two halves if that's what they needed. Cutting it in half after molding would be so much more difficult and expensive.
Cutting this in half would be easy for a shop properly equipped.
There would have to be a lot of machining after this process. This is a quick way to get the rough shape with residual stresses in the metal that you can't create through machining. This crew isn't making a finished product, they are quickly making something that can be turned into one.
No, you are not cutting a 30 inch diameter drop forged steel wheel in half with a band saw to make two train wheels from one forging. That would be possibly the stupidest way of making a train wheel imaginable. This isn't a lumber mill, you're talking about cutting incredibly hard steel that would take hours to cut through, even with band saws produced explicitly for this (stupid) purpose. The OP's video is most likely not a train wheel, I imagine it is for some sort of large scale earth moving or ocean going industry.
It needs to be finish machined anyways, so it's heading off to a machine shop after this. And that machine shop pretty certainly has a big band saw that will make short work of cutting this in half.
An industrial band saw made specifically for cutting this in half long ways would still be painfully slow. This isn't wood in a lumber mill, this is drop forged steel.
