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.
PRIMARY METALLURGY
The first step in steelmaking entails reducing iron ore to liquid iron or hot metal.
Production involves precise technical diagnosis and application follow-up by our thoroughly qualified technicians. We strive to ensure the highest levels of customer satisfaction.
Wire injection using Affival cored wire is the most cost-effective process for in-ladle treatment.

Analysis
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.

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.

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.

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.

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

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

Injection and Custom-Built Equipment
- Rotary Lance Injection
- Dual Lance Injection
- Multiple Outlet Injection
- Flow Control Valves
- Custom-Built Equipment
- Load Cell Calibration System
Our patented technology provides better dispersion of injection reagents leading to improved reagent efficiency, lower reagent consumption, reduced splash, and reduced temperature loss.

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

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

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.

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.

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.

Cored Wires
Shape control includes all calcium-bearing cored wires (powder and solid) such as PapCal®, Calcium HDx ™, Caltech, CaSi, CaFe, and CaAlFe. Our Ca wires are designed with special insulation to provide deeper penetration into liquid metal and improved performance.

Includes addition of metals and ferroalloys such as Titanium sponge, FeTi FeB, FeV, FeNb, FeMn, FeMo, and Carbon.

Aluminum is the most common deoxidizer in steelmaking and is useful as a grain refiner.

Nitrogen-bearing cored wire, used in steelmaking for controlled nitride formations.

Adding Sulfur, Fe, Lead, Bismuth, BiMn, Tellurium, or FeTeMn to improve machinability by forming specific and complex inclusions.

Metals and alloys, such as Rare Earths (Ce, La, Nd) and Zirconium, for highly specialized and customized applications to attain particular steel properties.

Nodulizer Cored Wires are based on magnesium content; the objective is to add magnesium in the liquid iron to modify and control the spheroidal shape of graphite during the solidification to produce Ductile Iron.

Inoculant Cored Wires control the structure and properties of cast iron, Lamellar, or Ductile Iron, by minimizing undercooling and increasing the number of nucleation sites during solidification.

Desulfurizer Cored Wires combine calcium with selected ingredients that desulfurize foundry iron while yielding no unreacted calcium carbide in the discharged slag, benefitting foundries facing environmental constraints on waste disposal.

Developed for steelmaking and cast iron foundry, cored wires are used in copper and brass melts for the addition of chemical elements as Mg, Cr, Fe, Ca, CuZr. Suitable for continuous or batch processes.
