Making steel from iron is the secondary refining process, also known as secondary metallurgy.

Steel producers are increasingly manufacturing high and low-carbon, structural, unique alloyed, and mechanical steel qualities, all of which have high requirements for resistance, strength, and purity. Inferior quality of raw materials increases process difficulties resulting from the presence of harmful residual elements such as sulfur, phosphorous, hydrogen, and non-metallic inclusion of SiO2 and Al2O3.

Opta can treat and even remove those impurities using secondary metallurgy, cored wires, and slag conditioners. Application of those products comprises precise technical diagnosis using state-of-the-art computer modeling, empirical data from in-situational use, and follow-up by highly qualified technicians. Opta ensures optimum results and customer satisfaction.

Steelmaking Products

Opta has a wide range of desulfurization products covering all areas of steelmaking, from hot metal to steel tapping fluxes to degassing fluxes.

Desulfurization Products

Opta supplies tapping sands for electric furnaces and nozzle sands for ladle needs. Our products include chromite, zirconia, silica, and olivine sands. We can customize sands for any operation to get the best free-open rate.


Insulators and fluxes for various steelmaking needs, from acid to basic practices. We sell standard products for ladles and tundishes, and we have developed specific fluxes, including our T3 series tundish flux used in the majority of the thin slab casters in the United States.

insulators and fluxes

We can custom-design a product to solve your problems.

Forms for metal melting

Optimize slag conditioners and tundish fluxes by understanding how they interact with your slag.


The chemistry of briquettes for secondary metallurgy applications has no real limit in killing steel, killing slag for desulfurization, improving alloy recovery, and slag conditioning.


Granular Lime or custom-blended products to achieve your deoxidizing, desulfurizing, or slag-conditioning needs.

Blended Granular Synthetic Slags

Next-generation, custom-blended products that provide better handling, precise melting points, lower energy consumption, no hydrogen pickup, and best-quality steel grade.

Sintered Synthetic Slags

Sintered custom-blended products to suit specific processing needs. The use of tundish cover permits the reduction of thermal losses and improves steel cleanliness.

Granular Slag Conditioning Products

Insulating Ladle Cover: A cost-competitive, emission-free, pelletized material for heat insulation.

Pelletized Products

Foamy slag, aggressive fluxes, and silicon pickup. Contact us with any special requirements.

Special Applications

Injection and Bulk-Handling Equipment

Our patented technology provides better dispersion of injection reagents leading to improved reagent efficiency, lower reagent consumption, reduced splash, and reduced temperature loss.

Rotary Lance Injection

Lance injection systems such as our patented Dual Lance system reduce injection times, decrease temperature losses, and improve lance life.

Dual Lance Injection

Our patented system allows one injection system to inject through two lances for a smaller overall footprint when there are space constraints.

Multiple Outlet Injection

A single-button method for applying scale-calibration weights and avoiding carrying loads to the top of the injector; reduces injuries and ensures more regular calibration and, therefore, greater injector-weight accuracy.

Load cell calibration system
Injection Equipment

Includes Powder Injectors, Automated Tanker Unloading System, Temperature Sampler Drive, Lance Drive, Flowbin Stand, Slag Skimmer, Nitrogen Bubbler Lance Drive, Industrial Panels, and Pneumatic Conveyor Systems.
