Production Equipment Required for Heat Resistance Wire Manufacturing

Production Equipment Required for Heat Resistance Wire Manufacturing

Producing heat-resistant wire (such as Fe-Cr-Al, Ni-Cr, or other high-temperature alloys) involves multiple stages, including melting, forming, drawing, annealing, and surface treatment. The required equipment includes:

1. Raw Material Preparation

• Vacuum Induction Melting Furnace (VIM) – Used to melt and refine high-quality alloys, ensuring purity and uniform composition.

• Electroslag Remelting Furnace (ESR) (Optional) – Further refines the alloy, reducing impurities and improving uniformity.

2. Casting & Forming

• Continuous Casting Machine – Produces billets or ingots from the molten alloy.

• Rolling Mill – Reduces the billet’s thickness and prepares it for wire drawing.

3. Wire Drawing

• Wire Drawing Machine – Gradually reduces the wire diameter through a series of dies, forming fine wires with precise dimensions.

• Multi-pass Drawing Machine – Used for ultra-fine wires.

4. Heat Treatment (Annealing & Oxidation Control)

• Continuous Annealing Furnace – Relieves internal stress, improves ductility, and optimizes electrical resistance.

• Atmosphere-Controlled Annealing Furnace – Prevents oxidation and ensures surface quality.

• Hydrogen Annealing Furnace – Used for ultra-high-purity applications.

5. Surface Treatment & Finishing

• Pickling & Cleaning Line – Removes oxides and impurities from the wire surface.

• Electrolytic Polishing Machine (Optional) – Enhances surface smoothness for specialized applications.

• Coating or Insulation Application System (If Needed) – Adds an insulating layer (e.g., ceramic coating, enamel coating for magnet wires).

6. Quality Control & Testing Equipment

• Spectrometer – Ensures the correct alloy composition.

• Hardness Tester – Checks mechanical properties.

• Tensile Testing Machine – Measures wire strength.

• Microstructure Analysis System – Examines grain structure for defects.

• Electrical Resistance Tester – Verifies the wire's resistance consistency.

7. Spooling & Packaging

• Spooling Machine – Winds the wire onto spools or coils for transport and storage.

• Automated Cutting & Packaging System – Prepares wire lengths according to customer specifications.

Optional Equipment for Specialized Production

• Plasma or Laser Cleaning System – Removes contaminants without damaging the surface.

• Vacuum Coating Machine – Applies special coatings for oxidation resistance.
