describe

The 1100°C five-sided heating box furnace delivers exceptional temperature uniformity, rapid heating, and precise thermal control for laboratory research, material testing, heat treatment, and industrial processing.

Product Features

Furnace temperature uniformity

• The 1100°C Five-Sided Heating Box-Type Electric Furnace is engineered to deliver outstanding temperature uniformity for precision laboratory and industrial heat treatment applications. The furnace achieves a temperature uniformity of ±5°C under no-load conditions, ensuring highly consistent thermal distribution throughout the heating chamber. This level of performance complies with the requirements of HB5425-2012, making it suitable for applications where accurate and repeatable temperature control is essential.
• Temperature uniformity is verified across a calibration range of 300°C to 1000°C, with measurements performed at five representative temperature points: 300°C, 450°C, 650°C, 850°C, and 1000°C. A five-point testing method is used to evaluate the heating chamber, ensuring reliable and objective performance verification before delivery.
• To guarantee measurement accuracy and product reliability, every furnace can be supplied with a third-party calibration report issued by a qualified and accredited testing organization. Upon customer request, the third-party agency can also perform on-site calibration after installation, ensuring that the furnace meets operational requirements under actual working conditions.
• In addition, calibration certificates for the temperature controller, measuring instruments, and thermocouples are provided to ensure complete traceability and compliance with quality management systems. This comprehensive calibration process gives laboratories, research institutions, aerospace manufacturers, and industrial users confidence in the furnace's precision, repeatability, and long-term performance for demanding thermal processing applications.

Exhaust port

• The furnace features a top-mounted manually operated exhaust vent designed to efficiently remove smoke, dust, moisture, and reaction-generated off-gases during high-temperature processing. This practical ventilation system helps maintain a cleaner furnace environment while improving operational safety, temperature stability, and overall process reliability.
• The adjustable exhaust vent allows operators to manually regulate the release of gases according to different heating processes, making it suitable for applications such as heat treatment, calcination, sintering, ash testing, ceramic firing, and material research. By promptly discharging volatile by-products and reaction gases, the system helps prevent gas accumulation inside the furnace chamber, ensuring a more stable processing atmosphere and consistent heating performance.
• Effective exhaust management also reduces contamination within the furnace, protecting heating elements, insulation materials, and other critical components from corrosive gases and excessive deposits. This contributes to longer service life, lower maintenance requirements, and improved long-term equipment reliability.
• The simple mechanical structure offers dependable operation without requiring complex control systems, allowing users to easily adjust airflow during operation based on actual processing conditions. This design provides greater flexibility for laboratories and industrial production environments where different materials generate varying amounts of exhaust gases.
• Overall, the manually operated exhaust vent enhances furnace safety, improves thermal process quality, maintains a cleaner working environment, and supports stable high-temperature performance, making it an essential feature for demanding laboratory research and industrial heat treatment applications.

control

• The furnace is equipped with an advanced closed-loop thyristor power control system that utilizes phase-angle or zero-crossing triggering technology to deliver continuously adjustable voltage, current, and power output. Supporting constant-voltage, constant-current, and constant-power operating modes, the system provides precise energy regulation for a wide range of laboratory and industrial high-temperature applications.
• Its intelligent dual-loop control architecture combines an inner current loop with an outer voltage loop, ensuring fast response and exceptional control stability. When sudden load changes occur or the operating current exceeds the preset limit, the controller automatically restricts the output current to the rated operating range. This protects both the power regulator and the heating system while maintaining uninterrupted furnace operation.
• The voltage loop continuously coordinates with the current loop to optimize output performance. As long as sufficient regulation margin is available, the system maintains stable voltage and current simultaneously, minimizing electrical fluctuations and ensuring consistent heating throughout the entire thermal process. This precise coordination significantly improves temperature stability and process repeatability.
• To maximize equipment reliability, the closed-loop control system effectively suppresses excessive current and voltage surges that could damage heating elements or electrical components. By reducing electrical stress during startup, load variation, and continuous operation, it extends heating element service life while lowering maintenance requirements.
• This high-precision power regulation technology delivers excellent safety, energy efficiency, and process consistency, making it an ideal solution for precision sintering, heat treatment, material testing, ceramic firing, powder metallurgy, and advanced laboratory research requiring stable and repeatable thermal control.
