Michelin buys loose coils of ca. 8mm and sucks it through several
zigzigs over ball bearing pulleys to straighten it.  Of course the
easiest way to suck it is with a capstan, which turns it back into
coil.  To get rod, I should think you'd have to have several sets of
aligned rolls -- just one set would slip or, if tight enough to do the
job, would deform the rod. It would take a pretty hefty motor to suck
1/2" through a series of zigzags.

Or I suppose you could winch it through 10' at a time with a
come-along. :-)


FWIW, the cold finished that I've had has always seemed to forge more
easily than the hot rolled.  But it has always been small sizes of
square presumably intended mostly for keys.

Isn't it about time that ABANA goes to a bankruptcy sale and buys its
own mini-mill?  Make 1003, "Pure Iron", real soft sheet for repousse
etc.
