With
the use of Sponge Iron the condition of slag worsen further as the slag contain
much higher percentage of Iron Oxide (FeO). Moreover, carbon reduction of the
steel promotes formation of iron oxide so the iron oxide content of slag is much
higher than where Sponge Iron had not been used.
Our SVI-IFDOX is in powder form and dissipates on the slag very fast. It is
having very potent deoxidizers for the steel and reacts quickly with the Iron
oxide in the slag and deoxidizes the available slag first and then steel.
Quantity : Approx 0.5 Kg per ton.
How to use : Before slag off add SVI IFDOX 0.5
Kg per T and rabble the mix thoroughly. The slag will start to foam. Remove the
foamy slag.
Expected Benefits :
| |
Saving in consumption of Ferro to Silicon |
|
Better recovery of Silico to Manganese |
| |
Improvement in steel quality |
|
Recovery of Fe from slag |
For Electric Arc Furnace EAFDOX of specification Aluminium 7 to 9 and alumina
70 to 75 is used for fluidizing the slag, For the same basicity higher the alumina
more fluid is the slag. So even slag with basicity of 4.5 5.0 can be made fluid
by controlling alumina. It is suggested to add before start of LF process preferably
at temperatures

beyond 1590 degrees centigrade.
