We make our cored wire using low-carbon, low-sulfur steel sheath, where we tightly encase powdered minerals, metals, and ferroalloys. These powders are precisely added in a way that ensures consistent chemistry and density throughout the length of every coil we produce. Our calcium wires are designed with a special insulation to provide deeper penetration into liquid metal and improved performance.
CORED-WIRE TREATMENT
CUTTING-EDGE TECHNOLOGY
Affival was the first to produce cored wire, and we remain the world leader in cutting-edge cored-wire technology.
Our technical team can leverage our newly developed calcium treatment model to optimize your calcium-wire treatment and improve recovery.
Wire injection using Affival cored wire is the most cost-effective process for in-ladle treatment.
At Affival, we understand that the equipment you use for application is just as important as the product itself. We offer a wide range of Wire Feeder options that can be designed specifically for your setup. For more information on our Wire Feeder Equipment and Engineering, click here.
Cored wire can contain any of the following:
CaSi HDx
Affival HDx cored wire allows calcium to react deeper in the ladle for the most cost-effective results and superior inclusion morphology.
Aluminum Deoxidizer
Aluminum is the most common deoxidizer in steelmaking and is useful as a grain refiner.
Re-Nitriding
Nitrogen-bearing cored wire, used in steelmaking for controlled nitride formations.
Machinability Improvement
Adding Sulfur, Fe, Lead, Bismuth, BiMn, Tellurium, or FeTeMn to improve machinability by forming specific and complex inclusions.
Specialty
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
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
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
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.
Copper Cored Wires
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.
