1700°C High-Temperature Double-Shell Box-Type Sintering Muffle Furnace

This 1700°C high-temperature double-shell box-type sintering muffle furnace is an advanced device designed specifically for high-temperature sintering processes. Its unique double-shell design and superior performance enable stable operation at temperatures up to 1700°C, providing a reliable high-temperature sintering solution for both scientific research and industrial production.

I. Core Performance

High-Temperature Capacity: This muffle furnace can reach temperatures up to 1700°C, meeting the sintering requirements of a variety of high-melting-point materials, such as certain specialty ceramics and high-temperature alloys. Its heating elements utilize high-quality silicon-molybdenum rods, which exhibit excellent stability and oxidation resistance at high temperatures. They can operate in environments up to 1700°C for extended periods, ensuring continuous heating.

Temperature Control: Equipped with a high-precision intelligent temperature control system, this system utilizes an advanced PID control algorithm and a sensitive temperature sensor to achieve a temperature control accuracy of ±1°C. During the sintering process, the effects of temperature fluctuations on material properties are effectively avoided. For example, when sintering high-temperature ceramics, precise temperature control ensures optimal density and mechanical properties. The system also supports multi-stage programmable temperature control, with up to 30 programmable ramp-up, hold-down, and ramp-down steps, meeting the complex sintering requirements of diverse materials.

Excellent Temperature Uniformity: A scientifically designed furnace structure and heating element layout ensure uniform temperature distribution within the furnace. Multi-sided heating, such as four or five-sided heating, combined with a thermal cycle within the furnace, maintains temperature uniformity within the furnace to within ±5°C. This is crucial for ensuring consistent sintering quality across batches of samples. For example, in the production of electronic ceramic components, a uniform temperature field ensures highly consistent performance parameters across each component.

Energy-Efficient: The double-layer furnace shell design, combined with high-quality insulation materials, significantly reduces heat loss. The inner shell is constructed of high-temperature-resistant material, while the outer shell is constructed of highly insulating material. An air barrier is formed between the two layers, minimizing heat conduction. The furnace chamber utilizes a high-density ceramic fiber material as insulation. This material has low thermal conductivity and excellent insulation properties, effectively preventing heat from escaping. Compared to traditional muffle furnaces, it achieves over 40% higher energy efficiency, significantly reducing operating costs.

II. Structural Design

Double-layer furnace shell: The furnace shell features a double-layer design. The outer layer is constructed of high-quality cold-rolled steel plate, pickled and phosphated, and then sprayed with high-temperature plastic. This aesthetically pleasing material offers excellent corrosion resistance and mechanical strength. The inner shell is constructed of high-temperature-resistant stainless steel, capable of withstanding long-term baking at 1700°C without deformation. A forced air cooling system is installed between the two layers of the furnace shell. A fan draws cool air into the interlayer, rapidly dissipating heat from the shell surface and keeping the outer shell temperature below 60°C, preventing burns to operators and minimizing the impact on the laboratory environment.

Furnace Design: The furnace chamber is constructed of vacuum-formed, high-purity alumina fiber material, which is characterized by high-temperature resistance, light weight, and low heat storage. The shape and size of the furnace chamber can be customized to accommodate sintering samples of varying sizes. The smooth interior prevents sample adhesion and facilitates cleaning. Furthermore, the furnace chamber offers excellent thermal shock resistance, withstanding rapid temperature increases and decreases without cracking, extending the furnace's service life.

Furnace Door Design: The side-opening door allows for flexible and convenient opening and closing. A high-temperature-resistant silicone seal is used between the door and the furnace body, ensuring a tight seal and minimizing heat leakage. Select models feature an observation window made of high-temperature-resistant quartz glass, allowing operators to observe the sintering progress of samples in real time without opening the door, thus avoiding temperature fluctuations caused by frequent door openings. Furthermore, the furnace door features a safety interlock that automatically shuts off the heating power supply when the door is opened, ensuring operator safety.

III. Intelligent Control System

User Interface: Equipped with a large, intuitive color touchscreen, the user interface allows easy operation, including temperature setting, program editing, and parameter query. The touchscreen also displays real-time information such as furnace temperature, heating power, and operating time, allowing operators to monitor the equipment's operating status.

Program Control: Supports custom editing of multiple sintering programs. Operators can set different heating rates, holding temperatures, and holding times based on the material's sintering process requirements. The equipment automatically runs according to pre-set programs, eliminating the need for manual intervention, improving efficiency and reducing human error. Programs can be saved and recalled, facilitating repeated production or experimentation with the same process.

Data Logging and Communication: The equipment's built-in data storage module automatically records temperature data and equipment operating status during the sintering process for up to several months. This data can be exported via USB, facilitating data analysis and process optimization. The equipment also features an RS485 communication interface, allowing connection to a computer or laboratory management system for remote monitoring and control, facilitating centralized management of multiple units.

IV. Safety Assurance

Multiple Protection Mechanisms: The equipment is equipped with multiple safety features, including over-temperature protection, burnout protection, overcurrent protection, and leakage protection. When the furnace temperature exceeds the set upper limit, the over-temperature protection device immediately shuts off the heating power and sounds an audible and visual alarm. If a thermocouple fails, the burnout protection function activates promptly to prevent the equipment from losing control. Overcurrent and leakage protection ensure electrical safety, preventing accidents caused by circuit failures.

Emergency Stop Button: The equipment's control panel features an emergency stop button. In an emergency, pressing this button immediately halts all operations and shuts off the heating power, ensuring the safety of both personnel and equipment.

Grounding Protection: The equipment utilizes reliable grounding protection, connecting the metal casing to the earth to prevent electric shock to the operator due to leakage.

V. Application Areas
