No. They involve working with large amounts of molten steel and
forcing air, oxygen-rich iron ore, or pure oxygen into them to burn
out the excess carbon, while fluxing the whole mess to remove unwanted
elements.

The number of people involved is not a good way to define small scale.
I toured the Nucor steel mill in West Seattle and there were only
about a dozen people working per shift.
