the coils are automatically purged with
protective atmosphere (N2 + H2). Working
on a step continuous basis, the stacks are
transported by rollers from one stationary
position to the next.
Once a pre-set cycle time has elapsed
the stack is driven into the vacuum
chamber where a vacuum is created.
After a predetermined time, the chamber
is then refilled with the process protective
atmosphere, and the stack is advanced into
the entry vestibule, where it remains for one
cycle before going into the furnace.
The high convection furnace is indirectly
heated under protective atmosphere, and
the complete line from entry vestibule to
the end of the cooling zone remains under
protective atmosphere 100 per cent of the
time. The stack of coils moves through the
furnace on a step continuous basis during
which time the coils are automatically
purged by the CTP system. This serves the
purpose of removing any oil from the bores
of the tube as it vaporises, which assists in
producing the so called ‘Super Clean’ tube.
At the end of the heating phase the stack
is passed into the cooling section, where
the material temperature is reduced to a
level below that which copper oxidises
when it comes into contact with air. The
stack is then discharged from the line via
the exit vacuum chamber, it is transported
to the destacking device, and the coils
are removed from the separated trays.
A complete materials handling system is
included for the conveying, stacking and
de-stacking of the work trays.
