New technology to produce square and
rectangular tubes
FIVES presented its new Oto hollow
shape forming technology during an
open house in November, in Boretto,
Italy. The open house assembled
Çinar Boru (Turkey), Profiltubi (Italy),
Marcegaglia (Italy) and other clients and
partners.
The new technology Oto HSU tube
mill (hollow shape universal forming
mill) has been in development since
2009. It is specifically designed to
produce square and rectangular tubes
for the construction industry. The mill will
produce HSU tubes at a lower production
cost through direct forming, skipping the
traditional step of constructing round
tubes and then squaring them.
The Oto HSU line is composed of a
mill with forming stands
that allow for strip
bending at precise angles
for the first and second
bends. The remaining
equipment consists of a
high-frequency welding
stand, a scarfing unit,
cooling and sizing
sections, straightening
and cut-off units, and a
packaging system.
The main benefit of
the Oto HSU technology
is the capability of frequent production
changes without a roll change. The range
of products can vary from a minimum
size of 20x20mm to a maximum size of
140x140mm within a range of four mills,
with a maximum production speed of
120m/min.
“This new technology guarantees
the possibility to produce hollow shape
tubes within a large range of dimensions
and thickness without changing rolls,”
said Andrea Anesi, operation director of
Fives Oto SpA, a concept designer of
the Oto HSU mill.
“Therefore, it substantially saves set-
up time, reduces investment cost in
different types of rolls and required floor
space for rolls, as well as it minimises
operator tuning.”
