2.Introduction
Carbon paste is conductive materials supplying
electric furnace equipment of ferroalloy furnace and calcium
carbide furnace ect.It can endure high temperatures, has smller
expansion coefficient and resistance coefficient which can reduce
the loss of electric.And it has smaller porous ratio,making heated
electrode slow oxidation .Higher mechanical strength makes sure
that the electrode isn't broken under the influence of machine and
electric load.
The current carries out smelting through arc produced by
electrode ing furnace.The electrode plays an important role in
the whole electric furnace.Without electrode,electric furnace can
not be used.The electrode only made of carbon having property such
as high oxidative resistance and electrical
conductivity can work normally under the temperature produced
by arc,because the carbon electrode can only slowly oxidize
enduring arc temperature of ***0 degree.
3.Types and main application
In accordance with the way it used,it belongs to
soderberg electrode.The working current density of soberberg
eletrode made by carbon paste is low as **6Acm,and the conductive
property of it has large difference comparing with graphite
electrode or carbon electrode.But the production of carbon paste
has low requirement of raw materials,simple manufacturing process
and low cost.The main material of production of carbon paste is
anthracite and furnace coke.There are 2 kinds of different
components of carbon paste.
1.So-called standard carbon paste.It is widely used in alloy
smelting furnace and carbide furnace.This kind of carbon
paste uses medium pitch of which softening point is at ****5
degree(mercury method) as binder.
2. Another kind of carbon paste is used in sealing ferroalloy
furnaces or calcium.Sealing ferroalloy furnace requires high
conductivity and thermal conductivity and sensible speed of
sintering.So the ingredient of production of this kind of carbon
paste which is different from standard carbon paste,it needs
graghitization metallurgical coke with high conductivity ,thermal
conductivity or graphite scraps,green petroleum coke,coal tar other
than anthracite as raw materials.The binder is also mixture
of coal tar and coal tar pitch.
In addition to two kinds of carbon paste above,some places
product carbon paste adding local natural graphite and
metallurgical coke or pitch coke.
