OPTA’s slag conditioners are used to adjust slag chemistry and/or viscosity, facilitating efficient sulfur removal and inclusion engineering. In addition, slag conditioners enhance alloy yields, inclusion removal, refractory protection, and desulfurization. Slag insulators are also used to inhibit temperature loss in the iron and steelmaking process.

By combining physical slag analysis and our innovative simulation capabilities, our products can be tailored to meet specific operational needs.

Opta’s technical team can develop a custom solution for high-quality steel production.

Steel production demands excellence in resistance, strength, and purity. Impurities like sulfur, phosphorus, hydrogen, SiO2, and Al2O3 hinder the process. With our expertise in secondary metallurgy, cored wires, slag conditioners, and fluxes, our solutions can eliminate these impurities.

We utilize advanced computer modeling, real-world data, and a team of highly qualified technicians to ensure optimal results and customer satisfaction. Elevate your steel quality with Opta.

Steelmaking Products

Desulfurization Products

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

Slag Deoxidizer

Opta utilizes custom blends to develop solutions that enhance the predictability and uniformity of slag deoxidation, even under highly variable slag conditions. By optimizing the reaction rate and efficiency of our products, Opta effectively minimizes the need for extended secondary processing time.


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 & Fluxes

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.

Metallurgical Assistance

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

Slag & Inclusion Analysis

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.

Blended Granular Synthetic Slags

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

Sintered 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.

Granular Slag Conditioning

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