  • Repeat replacement planning

Application Evaluation Matrix

Downtime riskReduced by spare inventory planningFurnace operations often depend on consumable graphite parts staying available.

Load pathPart weight, supported span, fixture load, and contact pointsGraphite trays and supports need geometry and grade choices matched to real mechanical loading.

RFQ Preparation Checklist

  1. Drawing or sample dimensions
  2. Temperature, atmosphere, and load
  3. Failure mode if replacing a broken part
  4. Quantity and shipment deadline
  5. Critical flatness, parallelism, or support surfaces
  6. Packing, spare-set, and maintenance shutdown requirements

Risk and Mitigation

  • Part cracks in service: Check geometry, material grade, load, and thermal cycling before quoting repeat parts.
  • Large plates or trays arrive damaged: Plan crate support, edge protection, and inspection photos for fragile hot-zone components.
  • Replacement part repeats a known failure mode: Review the broken sample, furnace cycle, load case, and grade before simply copying dimensions.

Buyer FAQ

Do you only make new furnace designs?

No. Many RFQs are replacement parts for existing hot zones, fixtures, and consumables.

What information helps when a furnace part failed?

Photos of the failure, operating temperature, atmosphere, load, support points, and the original drawing help identify quote and DFM risks.

Can you support spare-part programs?

Yes. Repeat drawings, revision control, and planned batch quantities help reduce downtime risk for maintenance shutdowns.
