The folks around here have been packing the pipe or box section stock 
with sand, welding the ends shut, and gently treating it as if it were 
solid.  The sand supports the sides, preventing, but not eliminating, 
collapse, so go gently.  When the forging is done, cut the ends off, 
and empty the sand.

I have had good luck drawing out square tube. You are basically upsetting
the sides as you forge the top. Go slow and keep it hot. Work evenly (if
you want a straight taper). The thicker the wall the better.
