1400 degrees programmable temperature control high temperature box-type refractory muffle furnace

1400°C Programmable Temperature-Controlled High-Temperature Box-Type Refractory Muffle Furnace. Having demonstrated outstanding performance in industrial applications such as material sintering and ceramic calcining, the 1400°C programmable temperature-controlled high-temperature box-type refractory muffle furnace is expanding its application with technological advancements. The newly developed third-generation product utilizes a composite ceramic fiber liner and a gradient temperature field design to increase thermal efficiency to 82%. This also addresses the industry pain point of traditional equipment prone to thermal stress cracking during rapid temperature increases and decreases.

In terms of intelligent control, the device is equipped with a multi-channel data acquisition system that monitors the dynamic changes of 16 temperature zones within the furnace in real time and automatically corrects temperature deviations using a machine learning algorithm. The user interface utilizes an industrial-grade touch screen and supports cloud-based downloading of process recipes, allowing users to remotely monitor key parameter curves during the sintering process. Test data shows that after 200 hours of continuous operation, the temperature control accuracy remains within ±1.5°C.

The 1400°C programmable temperature-controlled high-temperature box-type refractory muffle furnace is a high-temperature device commonly used in scientific research, university laboratories, and industrial and mining enterprises. It is primarily used for sintering, annealing, and quality inspection of materials. The following is a brief introduction:

Structural Features:

Furnace Material: Typically made of 1600-gauge alumina polycrystalline fiber inorganic material formed by vacuum adsorption. This material offers excellent thermal insulation and high tensile strength. The interior surface of the furnace can also be coated with a high-temperature insulating coating to improve heating efficiency and furnace life.

Furnace Structure: Mostly a double-layered furnace shell, it utilizes air insulation technology coupled with a thermal induction-driven intelligent air cooling system to effectively reduce the furnace shell temperature while increasing heating and cooling speeds.

Heating and Temperature Control System:

Heating Elements: Typically, high-quality silicon carbon rods are used as heating elements, offering high heating efficiency and long service life.

Temperature Control: Utilizing an intelligent temperature control system with PID regulation and auto-tuning, this system allows for programming of multiple temperature ramps (e.g., 8, 30, or 50 steps) with a temperature control accuracy of ±1°C. Some models also feature a data conversion interface for computer connectivity, enabling remote control, real-time tracking, and historical data logging.

Safety: Features include an over-temperature alarm and power-off function, as well as leakage protection, ensuring safe operation. Furthermore, the furnace door typically features a door-opening power-off function, which automatically shuts off power when the door is opened to prevent the risk of electric shock.

Applications: Primarily used in universities, research institutes, and industrial and mining enterprises for powder roasting, ceramic sintering, high-temperature testing, material processing, and quality inspection.

The safety protection system has also been comprehensively upgraded. A three-stage pressure relief device combined with a nitrogen protection port effectively prevents sample oxidation risks. The unique rapid cooling module can reduce the furnace temperature from the high operating temperature to below 200°C in just 3 minutes, significantly shortening experimental cycles. Currently, this equipment has been successfully used in the research and development of new solid-state battery electrolyte materials, and its stable high-temperature environment provides key support for the regulation of material crystal phase.
