Met Coke for Injection/Charge
Alloy steel makers inject Met Coke for slag Foaming. The carbon in Coke reacts
with FeO in slag. This results in Fe reversal into bath thus foaming the slag.
The foamed slag helps heat retention and reduces arching impact on
refractories. Met Coke is supplied in different sizes and Carbon as per
requirement of customers.

In the Induction Furnace melting it is normally difficult to get the Slag deoxidized and get 'White Slag' as in the Electric Arc Furnaces. The formation of 'White Slag' ensure in a way that the steel is in a better state of deoxidation and the slag is having very low Iron Oxide (FeO) content which also denote that steel quality should be better.
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 BenefitsSaving 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.
It is an insulation mineral, poor conductor of heat and electricity. Raw vermiculite expands to 14 times on heating about 850 Celsius. Expanded Vermiculite is light weight (low bulk density) and chemically inert.

USES: Exfoliated Vermiculite finds use in Agriculture and horticulture and also in dry crops as a carrier of water, pesticide and fertilizer and herbicide.
It also finds industrial application in the form of insulation bricks and particle boards and electrical and thermal insulation.
