GPC Recarburizer Supply for a European EAF Steelmaker

Challenge: The steelmaker needed a consistent supply of low-sulfur, low-nitrogen graphitized petroleum coke (GPC) recarburizer for short-cycle electric arc furnace operations, where unreliable carbon pickup and variable particle size were driving off-spec heats and excess off-gas carbon losses.

Solution: We aligned the specification on fixed carbon, sulfur and nitrogen limits and particle size, set a rolling delivery schedule with buffer stock near the mill, and provided lot-level chemistry documentation for each shipment to support charge control.

Result: Carbon uptake became predictable heat-to-heat, reducing recarburizer over-addition by roughly 15% and cutting off-gas carbon losses, while off-spec heats from carbon deviation dropped to near zero across the supply period.

Magnesium Co-Injection for Deep Hot-Metal Desulfurization

Integrated steel plant

Magnesium Co-Injection for Deep Hot-Metal Desulfurization

Challenge: The plant needed to desulfurize hot metal reliably to below 30 ppm for a range of low-sulfur and extra-low-sulfur steel grades, but calcium carbide alone gave inconsistent results and downstream ladle cleanup was costly.

Solution: We supplied high-purity magnesium granules in a controlled size range and supported a CaC2 + Mg co-injection practice, matching injection rates to target sulfur and holding buffer stock at the torpedo-car station.

Result: Hot-metal sulfur was held below 25 ppm across production cycles, reducing ladle-furnace desulfurization load and the reagents needed for final cleanup on low-sulfur grades.

Ferrovanadium and Vanadium Nitrogen Alloying for an Automotive Steel Producer

Automotive steel producer

Ferrovanadium and Vanadium Nitrogen Alloying for an Automotive Steel Producer

Challenge: The producer needed stable vanadium yield and fine, uniform grain refinement across a high-strength low-alloy (HSLA) line, but inconsistent vanadium alloy chemistry was causing scatter in tensile properties and occasional rejects.

Solution: We supplied certified ferrovanadium and vanadium nitrogen alloy with tight chemistry documentation, and supported a combined charging practice that balanced free vanadium for strengthening with vanadium nitrogen for precipitation.

Result: Tensile-property scatter narrowed and off-spec heat rejections fell, giving the line more predictable strength and better yield across the HSLA grade portfolio.

High-Purity Manganese Metal for a Specialty Steel Mill

Specialty steel mill

High-Purity Manganese Metal for a Specialty Steel Mill

Challenge: The mill was producing special-steel grades where impurity carry-over from standard ferromanganese was pushing sulfur and phosphorus up, forcing more downstream cleanup and occasionally missing tight compositional windows.

Solution: We supplied high-purity electrolytic manganese metal with documented impurity limits and supported a charging strategy that combined it with ferrosilicon to meet manganese targets without dragging in excess impurities.

Result: Special-steel heats met their tight compositional windows more consistently, reducing cleanup reagent use and improving yield on the most demanding grades.

Dolomite Dolime for Ladle Slag Conditioning at a Flat-Rolling Mill

Flat-rolling mill

Dolomite Dolime for Ladle Slag Conditioning at a Flat-Rolling Mill

Challenge: The mill needed to raise slag MgO saturation to protect the ladle refractory and improve slag fluidity, but inconsistent lime-only fluxing gave variable basicity and refractory wear that shortened campaigns.

Solution: We supplied dolomite dolime blended with lime to target a controlled slag basicity and MgO level, with documentation on each lot and a steady delivery schedule matched to ladle practice.

Result: Slag behavior became more consistent, refractory erosion in the ladle crown slowed, and the mill extended its campaign length while keeping basicity on target.

Ferrosilicon Deoxidation and Molybdenum Control for a Stainless Producer

Stainless steel producer

Ferrosilicon Deoxidation and Molybdenum Control for a Stainless Producer

Challenge: The producer needed tighter control of silicon during deoxidation of austenitic stainless heats — over- or under-shooting silicon was off-spec — while also keeping molybdenum yield stable across the grade range.

Solution: We supplied graded ferrosilicon and a deoxidizer matched to the austenitic practice, plus documented ferromolybdenum, and supported a charging plan that targeted silicon to the grade window rather than a blanket margin.

Result: Silicon landed inside the grade window on a higher share of heats, off-spec rework fell, and molybdenum yield stayed stable across the stainless portfolio.

Nodularizer and Inoculation Practice for a Ductile Iron Foundry

Ductile iron foundry

Nodularizer and Inoculation Practice for a Ductile Iron Foundry

Challenge: The foundry was seeing variable spheroidization and graphite-stringer rejects on ductile iron castings, traced to inconsistent nodularizer and inoculation material that could not be held to specification.

Solution: We supplied nodularizer and refined-slag inoculation material with documented chemistry and a controlled size range, and supported a standard inoculation practice with buffer stock at the ladle.

Result: Spheroidization rates became more consistent, graphite-stringer rejects dropped, and tensile properties steadied across the ductile iron range.

Bulk Calcium Silicon Deoxidation Under a Standing Delivery Contract

Long-product steel mill

Bulk Calcium Silicon Deoxidation Under a Standing Delivery Contract

Challenge: The mill consumed calcium silicon in large, steady volumes and wanted to lock both cost and specification — with tolerances in writing and a delivery schedule that never interrupted the melt shop.

Solution: We put a standing contract in place covering a defined calcium silicon specification, written tolerances, and a rolling delivery schedule with buffer stock, supported by lot documentation.

Result: Deoxidation cost per ton was stabilized, the specification held within agreed tolerances, and the melt shop ran without deoxidizer-related stoppages across the contract term.

Cored Wire for Inclusion Modification at a Wire-Rod Producer

Wire-rod producer

Cored Wire for Inclusion Modification at a Wire-Rod Producer

Challenge: The producer was making clean-bar and wire products where alumina inclusions were degrading surface quality, and their cored-wire supply was inconsistent in calcium yield and feed behavior.

Solution: We supplied calcium cored wire with documented chemistry and a controlled core, and supported injection parameters for speed and calcium yield suited to the producer's strand practice.

Result: Inclusion morphology improved, surface-quality rejects on clean-bar products fell, and downstream cold-work yield rose.

$Magnesia Carbon Refractory Supply Extending EAF Campaigns$

EAF / BOF steelmaker

Magnesia Carbon Refractory Supply Extending EAF Campaigns

Challenge: The steelmaker was losing campaign length to magnesia-carbon lining erosion and spalling, and patching with inconsistent spare refractory was extending outages more than it saved.

Solution: We supplied magnesia-carbon brick alongside high-alumina and firebrick spares as a matched set, with documented grade and consistent application support, delivered to keep a full repair kit on site.

Result: Refractory erosion and spalling slowed, campaign length extended, and hot-spot patching reduced outage time and refractory cost per tonne.
