By this
time the thick plume of rusty brown smoke would have abated and the
flame would be at maximum intensity. The oxygen in the air would have
burnt out the carbon and silicon and raised the temperature of the metal
to about 1600 deg C. If you were standing close by, the roar would be
deafening and the whole vessel would be shaking. You would either be
deeply impressed or terrified.

Chutes above
the vessel guided ferro silicon (to raise the temperature) or scrap
(to lower it) into the vessel. There are three slag bogies on the floor
below. The lettering "Stewart Demag" is visible, cast into
the waist band.

The mixer
is just visible beyond the corrugated sheeting to the left of the vessel.
