1400°C Industrial High-Temperature Heat Treatment Box Annealing Furnace

The core advantages of the 1400°C industrial high-temperature heat treatment box annealing furnace lie in its temperature control system and superior refractory structure. The furnace chamber utilizes multi-layer composite ceramic fiber modules with a high-purity alumina lining, effectively isolating heat loss while also withstanding the thermal stresses caused by repeated rapid cooling and heating. Intelligent control features an integrated PID control module and multi-point thermocouple monitoring, enabling temperature differences within the furnace to be controlled within ±3°C, ensuring uniform heating of the workpiece.

To meet the annealing requirements of various metal materials, this equipment features an innovative multi-stage programmable temperature ramp function. For example, when processing high-carbon steel, the system automatically implements a stepped temperature ramp: first increasing the temperature at a rate of 200°C/h to 650°C for stress relief and holding, then slowly increasing the temperature to above the AC1 line to complete austenitization, followed by controlled cooling through inert gas circulation. This flexible process design significantly reduces the risk of workpiece deformation and is particularly suitable for heat treatment of precision components in the aerospace industry.

The safety protection system also embodies industrial-grade design concepts. In addition to standard over-temperature alarms and power-off protection, the furnace door features a hydraulically linked sealing device that triggers a mechanical self-locking mechanism in the event of abnormal internal pressure. Notably, the flue gas treatment unit decomposes volatile organic compounds into CO2 and water vapor through a secondary combustion chamber, achieving emission targets far exceeding the new national environmental standards.

With the increasing popularity of 3D printed metal parts, the equipment's newly added vacuum option demonstrates unique value. Annealing at a negative pressure of 10^-3 Pa completely prevents surface oxidation of active materials such as titanium alloys, reducing machining allowances in subsequent processes by 40%. This upgraded model has been successfully applied to the post-additive manufacturing heat treatment of artificial joints.

The 1400°C industrial high-temperature heat treatment box annealing furnace is designed for high-temperature annealing of metal materials. It precisely controls the temperature at 1400°C to achieve the desired performance. The following is a brief introduction:

Main Features

High-Temperature Performance: High temperatures can reach 1400°C, with a typical continuous operating temperature of 1300°C, meeting the annealing requirements of a variety of high-melting-point materials.

High Temperature Control Precision: Utilizing PID control technology and S-type thermocouples, the temperature control accuracy reaches ±1°C, precisely controlling temperature fluctuations during the annealing process and ensuring consistent product quality.

High-Quality Heating Elements: Silicon carbon rods are typically used as heating elements, offering high load resistance, stable operation, and a long service life. They are evenly arranged on both sides of the furnace to ensure a uniform temperature field.

High-Quality Furnace Material: The furnace chamber is often constructed of high-purity alumina fiber, which features low thermal conductivity and heat capacity, minimizing energy loss. The inner furnace surface is coated with imported high-temperature alumina, enhancing heating efficiency and service life.

Excellent Safety: Equipped with overheating and thermal shutdown protection, as well as a door-opening power-off function, some units also feature dual-circuit control and protection, effectively preventing equipment failure and operator hazards.

Technical Parameters

Power Supply: Commonly AC 220V/50Hz. Power varies depending on furnace size. For example, the 8L furnace has a power of 5.2kW, while the 19L furnace has a power of 9kW.

Furnace Dimensions: Various sizes are available. For example, the 8L furnace chamber measures 200mm × 200mm × 200mm, while the 19L furnace chamber measures 250mm × 300mm × 250mm.

Heating Rate: A heating rate of ≤10°C/min is generally recommended to protect the equipment and ensure temperature control accuracy.

In the future, by integrating an IoT module, operators will be able to monitor real-time video streaming data from the furnace on their mobile devices. Combined with AI algorithms, this will elevate preventive maintenance to a new level.
