When Cored-Wire Spheroidizing Treatment Fits a Ductile Iron Process

Cored-wire spheroidizing feeds a steel sheath containing magnesium-bearing alloy into molten iron at a controlled rate. It can support repeatable dosing, automated treatment records and a more contained reaction than some open-addition methods.

The method is not a drop-in replacement for process control. Wire filling consistency, sheath dimensions, feed speed, ladle geometry, melt temperature and sulfur level all affect magnesium recovery. Post-treatment inoculation remains a separate step and must be planned around the available fading time.

What buyers should specify

  • Wire diameter and alloy fill per metre
  • Target magnesium and rare-earth chemistry
  • Coil weight, winding and moisture protection
  • Base iron sulfur and target residual magnesium
  • Feeding equipment and expected treatment weight

A controlled plant trial should confirm recovery and reaction behavior before routine production. Send the process details through the inquiry form for grade discussion.
