Opta is the world’s leading supplier of magnesium reagents, calcium-carbide, and lime-based carrier reagents for use in the iron desulfurization process.

We offer injectable ironmaking desulfurizing products as well as injection and custom-built equipment.

We strive to ensure the highest levels of customer satisfaction.

From the simple process of adding and stirring reagents into hot metals, to sophisticated means of deep injection, Opta makes products used in all forms of ironmaking. We customize our products according to the requirements of each process with agents made of calcium oxide, calcium carbide, metallic magnesium, and others.

Production involves precise technical diagnosis and application follow-up by our thoroughly qualified technicians.

Injectable Ironmaking Desulfurizing Products

Magnesium-Based Reagents

High Mg-content reagents can be co-injected with pulverized flow-treated lime or calcium carbide-based products into iron to achieve ultra-low sulfur aims.

Calcium Carbide-Based Reagents

Pulverized flow-treated calcium carbide can be used in co-injection or in multi-injection processes with lime and magnesium to reduce reagent consumption and injection time.

Fluidized Lime-Based Reagents

Pulverized flow-treated lime is an integral component in our proprietary blends with calcium carbide and magnesium powders—sized and blended to avoid segregation—and performs well as a mono or co-injected reagent.

Blended Reagents

Injectable flow-treated mixtures based on iron oxide, lime, and fluorspar can be used as mono-injection reagents in the dephosphorization process with high performance.

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.


Injection and Custom-Built 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

Patented valve systems such as our Variable Orifice Valve and Injection Nozzle Valve offer better control of reagent flow from injector vessels, paired with in-house PLC flowrate control software.

Flow Control Valves

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.

Custom-Built Equipment

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.
