Pure
copper
without
oxygen
and
without
any
deoxidizer
residue.
But
it
actually
contains
very
small
amounts
of
oxygen
and
some
impurities.
According
to
the
standard,
the
content
of
oxygen
is
not
more
than
0.003%,
the
total
content
of
impurities
is
not
more
than
0.05%,
and
the
purity
of
copper
is
more
than
99.95%.
Anaerobic
copper
products
are
mainly
used
in
the
electronics
industry.
Often
made
of
oxygen-free
copper
plate,
oxygen-free
copper
belt,
oxygen-free
copper
wire
and
other
copper
materials.
Strictly
distinguish,
anaerobic
copper
should
be
divided
into
ordinary
anaerobic
copper
and
high
purity
anaerobic
copper.
Ordinary
copper
without
oxygen
can
be
smelted
in
the
power
frequency
induction
furnace
with
iron
core,
while
high
purity
copper
without
oxygen
should
be
smelted
in
the
vacuum
induction
furnace.
Vacuum
smelting
should
be
the
best
choice
for
smelting
high
quality
anaerobic
copper.
Vacuum
melting
can
greatly
reduce
not
only
oxygen
content,
but
also
hydrogen
and
some
other
impurity
elements.
In
vacuum
medium
frequency
coreless
induction
furnace
smelting,
graphite
crucible
and
high
purity
cathode
copper
after
twice
refining
or
remelting
copper
are
used
as
raw
materials.
A
flake
graphite
powder
for
deoxidation
is
also
included
in
the
furnace
with
the
cathode
copper.
In
fact,
deoxidation
is
mainly
through
the
carbon
in
the
graphite
crucible
material.
The
carbon
consumption
can
be
calculated,
for
example,
1
kg
of
copper
consumes
100
grams
of
carbon.
Experience
shows
that
the
higher
the
oxygen
content
in
copper
liquid
at
the
beginning,
the
faster
the
deoxidation
reaction
at
the
initial
stage
of
smelting.
The
oxygen
content
of
the
oxygen-free
copper
obtained
by
vacuum
smelting
can
be
less
than
0.0005%,
and
the
hydrogen
content
is
less
than
0.0001%
~
0.0003%.
In
fact,
only
in
a
certain
degree
of
vacuum
smelting
and
casting
of
copper,
it
is
possible
to
get
completely
free
of
oxygen
and
other
gases
castings,
so
the
production
of
electronic
tube
copper
vacuum
furnace
vacuum
degree
should
be
above
10-6
Advantages:
1,
high
conductivity
2.
Good
thermal
conductivity
3,
good
weldability
4,
excellent
plasticity
and
ductility
5,
excellent
cold
working
performance
