Lower silicon
Reduce hot metal silicon in the blast furnace main runner and in hot metal ladles, for more consistent steel making.
Iron & steel ยท Hot metal treatment
Cleaner hot metal. Higher yield. Lower cost.
Nellikuru Innovations gives iron and steel makers a user-friendly way to lower hot metal silicon and cut yield losses, applied right in the blast furnace runner and the ladle.

What we do
Practical metallurgy that pays back on every heat
We are an R&D startup focused on iron and steel making in India. We turn proven chemistry into simple, shop-floor-ready reagents that lower silicon and protect yield, without a separate process step or heavy capital.
Higher yield
Insulate the metal from the moment it enters the ladle to cut temperature loss, oxidation and jamming.
User-friendly
No separate steel-making step and no oxygen blowing. Our reagents are added in the runner or at the bottom of the ladle.
R&D-driven
Built by inventors under the Make in India program, with the Nellikuru Process under patent.
Our solutions
Two innovations for the cast house
Both work with your existing flow, in the runner and the ladle, with no new process line.
Hot Metal Desiliconization
The patented Nellikuru Process lowers hot metal silicon in the blast furnace or COREX cast house, in the runner or the ladle. Low silicon is ideal for steel making.

Hot Metal Insulation Compound
Added at the bottom of the ladle before tapping, it forms an insulation layer the instant it meets liquid metal, floats with it, and stays intact until the metal is poured.

Why Nellikuru
Big-furnace results, without a big project
As raw material quality drifts and furnaces run at safer chemistries, external user-friendly desiliconization is the practical answer. Our reagents slot into your cast house and start working on the next heat.
Patented process
The Nellikuru desiliconization process is under patent.
Make in India R&D
The first startup of its kind in iron and steel making R&D in India.
Runner and ladle
Applied where it is convenient for you, with no separate process step.
Consistency
Helps steel making get the consistent hot metal quality it needs.
