It is not too much to say that the consumption
of electric power and graphite electrodes
accounts for the majority of the total steel
making costs in the E.A.F. method of steel
making. Especially, increasing the consumption
of electrodes will influence electric power
consumption as well as increasing the cost
of electrodes and increasing of operating
costs too.
It is said generally that the wearing of electrodes consist of "Tip-Wear"
and "Side-Wear" by oxidation and this "Side-wear" is
about 40 to 60% of total consumption of the electrodes due to the exposure
for long periods of time in the E.A.F. For many years, various methods
for lowering the consumption rates of electrodes have been released in
this industry but so far not a sufficient method to reduce consumption.
Our latest type CERACOATTM EL-300 for graphite electrodes, is the improved one on the performance
of our previous type CERACOATTM EL-100 which can decrease the consumption by side-wear sharply with the
easy dipping and impregnating method.
EL-300 was enhanced at the effect of reducing consumption of electrodes
by 10% 〜 30% than EL-100.
