Pig Iron making, in the Blast Furnace is generally discussed in terms of Coke or Carbon rates / THM.
Little is known why the BF's consume nearly double the stoichiometric Carbon.
Dr. PS Anand Prakash, has done intensive studies of the BF reactions & has come up with an unique solution for BF's.
Solidorff Polychemical as the name suggests is designed & perfected to achieve maximum failure of the Solution Loss Reaction (SLR) & Direct Reduction Reactions (DRR) in the BF directly resulting in lower Carbon / Coke rates up to 125 Kg / THM within 45 days of application.
Solidorff Polychemical acts as reaction filter or blocker between CO2 & C, extends its time, ultimately failing the SLR in the Thermal Reserve Zone.
The Coke so saved from SLR starts accumulating at the Tuyere & reaches a threshold limit and over the next few days, starts failing DRR, in the Bosh zone.
The following results are expected, within 45 days of application
Very High CO efficiency & Utilization
Entire furnace stabilizes with Indirect reduction
Heat Surplus in the hearth due to failure of DRR & SLR ( both are endothermic )
Carbon Surplus as the C recovered from DRR & SLR accumulate at the Tuyere
Increased Ore + Sinter volume for identical Coke batch
Increased BF productivity up to 20% to 25% at the same blast rates & blast temperature
Lower Slag Fe losses
Cohesive zones are nearly eliminated & BF hanging becomes a thing of the past
Extended TRZ by over 25 to 30%, reduction in Bosh zone volume by over 50 to 75%
Lesser volume of FeO undergoing DRR at Bosh
Highest & excellent furnace permeability
Lower Coke rates by Min. 50 Kg to 125 Kg / THM
Lower Specific CO2 per ton of Pig Iron produced
Consistently Sustainable condition of SLR & DRR failure in the furnace
No effect on Thermal Bricks as maximum heat is utilized by Slag & Hot metal
Furnace tapping time lowers
Increased Slag & Metal temperatures by over 100 to 125 deg C
No change in the BF exit gas temperatures
Solidorff is furnace neutral to RM, fluxes, Hot metal
BF's can work with lowest heat consumption & carbon consumption within 45 days of application, with highest productivity in the furnace.
BF's which are looking for Hydrogen adaptation can look at this solution & then can adapt Hydrogen solution.
Effectiveness of Solidorff : Can be established in the Lab, by testing C + O2 reaction blocking, which is 5 times more intense than CO2 + C reaction.
Coke rate reduction Contracts : We undertake BF Coke rate saving on contract & profit sharing basis.
Take only one decision to lower your coke rates & leave the rest to us.
