Steelmaking auxiliary materials

Five product families, each formulated for a specific stage of the steelmaking route. All produced in our own plant, and all adjustable to your operating conditions.

Hot Metal Ladle Covering Flux — powder grade

Covering Agent

Cut heat loss from molten steel. Stop secondary oxidation dead.

Spread on the molten bath, a Covering Agent melts into a continuous protective layer that holds heat in, keeps air out and absorbs the inclusions that rise to the surface.

Exothermic Hot Topping Compound — powder grade

Exothermic Hot Topping Compound

Keep the riser liquid. Get sound castings and a higher yield.

A thermit-type compound that ignites on contact with molten steel and keeps the riser head hot while the casting solidifies — so shrinkage cavities and pipe stay in the riser, not in your product.

Granular 0–6 mm grade, shown on a white dish to give a sense of scale

Slag Fluidizer

Thins the slag you already have — so the lime dissolves and the reactions speed up.

A Slag Fluidizer, not a slag former. Added at the converter or the refining ladle, it penetrates viscous high-lime slag, breaks down the calcium silicate network and pulls the melting point down — so lime that was sitting undissolved goes into solution and the slag you already paid for can finally do its job.

GDZ-1 Ingot Teeming Flux — micro carbon grade

Ingot Teeming Flux

Clean ingot surfaces. Fewer dressing hours. Less scrap.

Added to the mould during teeming, this flux forms a protective liquid layer that keeps oxygen away from the rising steel, lubricates the mould wall and helps gas and inclusions escape — for a smoother ingot surface straight out of the mould.

Ladle Sand — graded fractions, coarse through to fine, selected to fit your nozzle bore

Ladle Sand

First tap opens. Every time. No oxygen lancing, no lost heats.

Filled into the ladle nozzle before tapping, this sand holds the steel back and then releases cleanly when the slide gate opens — so the ladle self-opens and you avoid oxygen lancing and the delays that come with it.
