Product Info

A Wire Rod Coil Annealing Furnace is a furnace used for annealing hot-rolled wire rods to improve their microstructure, reduce hardness, and increase the ductility of the material, making it easier to form and process the wire.

1️⃣ Working Principle of Wire Rod Coil Annealing Furnace
Annealing is a process of heating steel wire under controlled atmosphere and temperature, typically involving three main stages:
🔸 Heating Stage – Gradually increase the temperature of the steel wire to an appropriate level (typically between 600-900°C).
🔸 Soaking Stage – Maintain a certain temperature to allow microstructural transformations.
🔸 Cooling Stage – Slowly reduce the temperature under control to prevent residual stress in the material.

2️⃣ Benefits of Wire Rod Coil Annealing Furnace
✅ Increases ductility and flexibility – Reduces the brittleness of steel suitable for forming.
✅ Reduces internal stress in the material – Prevents cracking during forming.
✅ Improves the surface quality of the wire – Reduces oxide formation, making the wire shiny and smooth.
✅ Precise control over material properties – Suitable for high-quality production requirements.

3️⃣ Industrial Applications
Wire Rod Coil Annealing Furnaces are used in several industries, such as:
🔹 Steel Wire Industry – Used for annealing hot-rolled wire to prepare it for forming.
🔹 Spring and High Tension Wire Industry – Adjusts the microstructure of the wire for spring or cable production.
🔹 Nail and Staple Wire Industry – Reduces wire hardness for easier forming.
🔹 Automotive Industry – Used for producing metal parts like brake wires, cables, or metal structures.

4️⃣ Choosing the Right Wire Rod Coil Annealing Furnace for Your Needs
Before selecting this type of furnace, consider:
🔸 Size and quantity of wire to be annealed – Choose a furnace that supports your production needs.
🔸 Desired temperature range – Typically between 600-900°C.
🔸 Controlled atmosphere system – Atmosphere that prevents oxidation, such as nitrogen (N₂) or hydrogen (H₂).
🔸 Energy efficiency – Furnaces designed to save energy can help reduce production costs.
