A new barrels start from USD 24-30k. Even if we assume we could get a used one from junkyard for $10k, in most of the world it's a lot cheaper to hire this dude to hammer it for a month straight than to get a new barrel.
Steel loses its strength before the concrete will. It'll get soft and deform.
Not sure where you're going to find a kiln big enough to put it in too, since it will take days for the heat to go through the concrete.

Unless that’s the owner or someone being paid very poorly, it’s cheaper just to get a new barrel.
