COPPER MOULD ALLOYS
The copper alloys chosen for the moulds must maintain their
physical properties at the operating temperatures of the
continuous casting process.
The temperature gradation from the inner wall of the mould to
the outside face of the mould can cause serious distortion
problems ,and it is imperative that the correct alloy is chosen
for the various operating conditions.
STANDARD MATERIALS
Phosphorus de-oxidised copper
This alloy has been proven to be excellent for the manufacture
of moulds in the continuous casting of billets .The main
composition of this alloy are Cu +Ag
*9.*0min,P0.***5/0.**0.
Copper -Silver alloy
The addition of a small amount of silver ,whilst not increasing
the melting point of copper ,does increase the
recrystallisation temperature by almost **0℃,and also helps to
give better thermal conductivity at the operating
temperatures.
This alloy is normally used in moulds for the continuous
casting of blooms and slabs .In this case ,the moulds are much
thicker than in the billet moulds ,and the moulds temperature
can be higher.The main composition of this alloy are Cu+Ag*9.*0
min. Ag 0.*8/0.*2 O 0.**4/0.**2.
COPPER MOULD TUBE
The continuous casting of molten steel into billets ,blooms and
slab products ,has been highly refined over the years into an
extremely sophisticated system .The continuous casting process
is expected to produce metallurgically sound products at the
lower possible cost ,and this is being achieved in many
steelworks throughout the world.
Copper moulds have played an important role in the development
of the continuous casting process .Their funcition is to
receive the molten steel and to allow rapid heat transfer from
the steel to the cooling water to enable quick
solidification.
The mould must exhibit excellent thermal conductivity ,be
resistant for thermal erosion ,and be resistant to distortion
from thermal stress .So far only copper and a few copper alloys
meet the above conditions ,both economically and
technically.
SOLIDIFICATION
The rate of solidification in the continuous casting process
dictates the speed of production .The molten steel ,which is in
contact with the inner faces of the copper mould ,starts to
sllidify as rapidly as the heat is extracted ,forming a shell
.The shell increases in thickness as more heat is extracted
,and eventually total solidfication is achieved .the process is
similar to the solidification of ingots in ingot moulds .In
continuous casting ,the whole process is speeded up ,with the
aim to produce and homogeneous shell growth.Consequently ,the
mould is an important part of the continuous casting process
,and the manufactured quality of the mould plays and important
role in their length of life.
INNER SURFACE COATINGS
Over the years ,Metallurgists and Engineers have been working
together to develop better continuous casting moulds .The steel
companies require a more economical mould which will give a
longer service life .Surface coating of the inner walls of the
mould has given the best results to date .Coatings available
are Chromium and Nickel plating .Also,a combination of the two
give good results on slab casting.
