Transforming raw, brittle drawn wire into highly ductile, workable material requires an environment of absolute thermal stability. This electric annealing furnace is engineered to provide exactly that. When standing beside the unit on the factory floor, operators will notice the quiet, steady hum of the 380V three-phase power system driving the heating elements, a stark contrast to the intense 950℃ environment contained safely within. The exterior features a robust, powder-coated blue steel shell that remains remarkably cool to the touch, a testament to the dense refractory fiber insulation packed within its walls. This heavy-duty construction not only anchors the unit firmly to the industrial floor but also acts as a fortress against thermal loss.
Inside the cylindrical Φ850×800mm chamber, the atmosphere is meticulously controlled. As the heavy top cover seals shut with a reassuring metallic clank, the internal environment prepares for the rigorous heat treatment cycle. The furnace eliminates internal stresses built up during the wire drawing process, effectively resetting the crystalline structure of the metal. For production managers, this means an immediate reduction in wire breakage during subsequent processing stages. By maintaining a highly uniform temperature profile, the equipment ensures that every millimeter of the coiled wire receives the exact same thermal exposure, resulting in a consistent, flawless finish that meets the strictest industrial standards.

Maximizing facility output requires equipment that operates flawlessly under continuous strain. This thermal processing unit is designed with several distinct advantages that directly impact the bottom line of large-scale production facilities.
Rapid Thermal Recovery: The ability to bring an empty chamber to its operating temperature in under 60 minutes drastically cuts down shift preparation time, allowing for more processing cycles per day.
Adjustable Power Draw: The 60 KW power rating features a ±10% adjustable range, giving operators the flexibility to match energy consumption precisely to the load size, preventing unnecessary power waste.
Deep Chamber Architecture: The Φ850×800mm vertical cylindrical design accommodates large, heavy coils of wire, utilizing gravity to maintain coil stability during the softening process.
Seamless Integration: Designed to fit directly into existing factory workflows, the 380V/50HZ three-phase setup aligns with standard industrial power grids without requiring expensive electrical retrofitting.
The primary concern for any procurement manager is the physical integrity of the final product. This furnace excels at eliminating the internal mechanical stresses generated during the rigorous wire drawing process, ensuring your materials meet exact specifications.
Restored Ductility: By carefully raising the metal to its recrystallization point, the equipment restores the natural flexibility and elongation properties of the steel wire, making it ready for complex secondary processing.
Surface Integrity: When configured with the optional protective gas atmosphere, the chamber actively displaces oxygen. This prevents surface oxidation and decarburization, ensuring the wire retains a bright, clean finish.
Consistent Yields: The uniform thermal environment guarantees that the mechanical and electrical properties of the wire remain identical from the outer layers of the coil right down to the core, minimizing rejected batches.
Achieving a maximum rated temperature of 950℃ requires more than just raw power; it demands sophisticated regulation to prevent material degradation and ensure a perfectly timed thermal curve.
Intelligent Regulation: Driven by an advanced PID/PLC control system, the furnace constantly monitors and adjusts the heat input. This eliminates temperature spikes and prevents the localized overheating that often leads to brittle spots in metal coils.
Single-Zone Precision: The dedicated single heating area ensures a concentrated, highly stable thermal field, which is critical for the uniform softening of densely packed industrial materials.
Accelerated Processing: The high-efficiency electric heating elements allow the empty furnace to reach operational readiness in less than one hour, significantly accelerating daily production schedules and reducing idle time.
Energy consumption is a major recurring expense in metallurgical processing. This equipment is structurally optimized to keep thermal energy exactly where it belongs—inside the chamber—thereby protecting your operational budget.
Advanced Insulation: Lined with high-quality refractory fiber and composite insulation materials, the furnace walls present a formidable barrier to heat transfer. The exterior remains safe to approach, indicating minimal thermal leakage.
Optimized Power Usage: The adjustable 60 KW system ensures that the facility only pays for the energy required for a specific load, optimizing the cost-per-ton of treated metal.
Rapid ROI: By combining low empty-furnace heat loss with high-speed processing, the unit lowers overall electricity bills, resulting in a significantly shortened return on investment for the facility.
Operating at 950℃ inherently involves risk, which is why this system incorporates multiple layers of automated protection to safeguard both the personnel on the floor and the facility itself.
One-Touch Operation: The smart control panel simplifies complex thermal cycles into straightforward, repeatable programs, reducing the reliance on highly specialized manual labor and minimizing human error.
Over-Temperature Alarms: Independent sensors continuously monitor the chamber. If the temperature deviates from the programmed curve, audible and visual alarms are immediately triggered to alert operators.
Failsafe Mechanisms: Built-in power outage protection and safety interlocks ensure that heating elements are instantly deactivated if the furnace cover is compromised or if a critical electrical fault is detected.
Industrial procurement requires assets that will perform reliably for years under punishing conditions. The physical construction of this furnace reflects a deep commitment to longevity and continuous operation.
Heavy-Duty Shell: The exterior is fabricated from thick, precision-welded steel plates, designed to withstand the inevitable impacts, scrapes, and vibrations of a busy factory floor.
Heat-Resistant Core: Internal components, including the load-bearing bottom plates, are cast from specialized high-temperature alloys that resist warping and thermal fatigue over thousands of intense heating cycles.
Low Maintenance Architecture: By utilizing durable materials for critical internal structures, the frequency of component replacement is drastically reduced, minimizing unexpected downtime and maintenance labor.

Below are some of the most common technical inquiries we receive from facility managers and procurement specialists regarding our thermal processing equipment.
What type of maintenance is required for the refractory fiber insulation?
The composite insulation is highly durable and designed for long-term industrial use. Routine maintenance simply involves visual inspections every few months to ensure no physical damage has occurred from loading heavy coils. Under normal operating conditions, the lining will last for years without needing replacement.
Can the PID/PLC control system interface with our existing factory management software?
Yes. The intelligent control systems can be configured with standard industrial communication protocols upon request, allowing for seamless data logging, thermal curve tracking, and remote monitoring from your central control room.
How does the protective gas configuration work, and what gases are compatible?
The furnace can be fitted with sealed retorts and gas inlet/outlet valves. It is compatible with nitrogen, argon, or specialized forming gases. This system actively displaces oxygen during the heating and cooling cycles, resulting in a bright, oxidation-free finish on the wire.
Is it possible to process multiple smaller coils simultaneously?
Absolutely. As long as the total dimensions fit within the Φ850×800mm capacity (or your customized dimensions) and the weight does not exceed the structural limits, multiple coils can be stacked. The uniform single-zone heating ensures all coils receive identical thermal treatment.
What happens in the event of a sudden power failure during a 950℃ cycle?
The system features robust failsafe mechanisms. Upon power loss, the heavily insulated chamber will retain its heat, cooling down very slowly. This prevents sudden thermal shock to the metal inside. Once power is restored, the PLC can be programmed to safely resume the cycle or execute a controlled cooling protocol.
