A ferroalloy producer required replacement contact shoes for a submerged arc furnace electrode system.

Customer Requirement

The parts had to fit existing mechanical interfaces while maintaining stable electrical contact.

  • Contact faces and mounting geometry were treated as critical characteristics.
  • The selected material needed conductivity and mechanical strength.
  • Consistent identification was required for repeat installation.

Manufacturing Route

The project used controlled material preparation, forging, heat treatment and precision machining.

  • Machining datums were aligned with contact and mounting features.
  • Final surface condition supported the specified electrical interface.
  • Material and dimensional records remained linked to each batch.

Supply Outcome

The approved data and inspection route created a repeatable replacement-part supply basis.

  • Parts were marked and packed by installation set.
  • Inspection reports supported incoming verification.
  • The finalized drawing reduced clarification for repeat orders.
