Order for steel tube annealing machine
PLASMAIT reports that 2015 was an
exciting time for its team in Austria. One
of the orders received by the company
last year included an annealing line
for precision stainless steel and nickel
alloy tubes with OD range 0.6-10mm.
The order reaffirmed the success of
Plasmait in stainless steel heat and
surface treatment applications that
now include wire, tube, strip and rope
annealing and hardening.
The line was built for a producer
of small-size precision tubing whose
prime concern was the quality of
recrystallisation, as well as clean, bright
and scratch-free finish of the tube
surface. Plasmait’s solution offered the
client a modern, computer-controlled
facility designed for ease of use and
minimal environmental impact.
Plasmait now offers annealing lines
with outputs of up to 170kg/h per line
for austenitic, and more for martensitic
stainless steels. The new facility occupies
a fraction of the space that would be
required by a conventional multi-line
annealing furnace of the same capacity.
A single plasma line can substitute
around 20 traditional lines.
The annealing line features high
energy conversion efficiency, low
purging gas consumption, quick
string-in, and computer-based quality
control. PlasmaAnnealer can cold start
production in a few minutes and can be
stopped immediately. This avoids lengthy
heating-up and cooling-down times
and associated energy costs that are
symptomatic of a conventional furnace.
Ion sputtering on the material surface
results in dry surface degreasing and
surface oxide removal, which have
proved beneficial to applications with
demanding surface requirements
in sectors such as medical, heat
exchanger, food processing, chemical,
aerospace, aviation and automotive.
Plasmait also sold annealers for
producers of fine medical tubes
with sizes down to 0.2mm OD. The
annealing speeds on small-size tubes
are high enough to allow annealing to
be performed in-line with drawing. Tube
producers now require fewer take-ups
and payoffs, which reduces the total
cost of equipment.
