1. Large diameter design: improving processing capacity and material adaptability
High efficiency in batch processing
A large pipe diameter (such as a diameter of 180mm or more) allows for the simultaneous placement of multiple samples or large materials, which can greatly increase the processing capacity of a single experiment or production. For example, in scenarios such as crystal growth and ceramic sintering, multiple samples can be processed simultaneously to shorten the overall cycle.

Compatible with complex shaped samples
The large diameter design can accommodate irregularly shaped or elongated materials (such as metal rods, ceramic tubes, etc.), avoiding experimental deviations caused by size limitations and meeting diverse material processing needs.

2. Rotation function: achieve uniform heating and efficient reaction
Greatly improved temperature uniformity
The rotating mechanism causes the material to roll 360 degrees inside the furnace, avoiding local overheating or underheating. For example, during the sintering process of powder materials, rotation can ensure that the powder particles are uniformly heated, improving the density and consistency of the sintered products.

Promote sufficient gas material contact
The rotation accelerates the gas flow inside the furnace, making the protective atmosphere (such as inert gas) or reaction gas more evenly wrap around the surface of the material. This is important in processes such as semiconductor material coating and metal reduction reactions, which can greatly improve reaction efficiency.

Simulate dynamic working conditions
The rotation function can simulate the dynamic conditions in actual production (such as material conveying, stirring, etc.), providing experimental basis for studying the performance changes of materials in dynamic environments, and making the results more closely related to practical applications.

3. High temperature capability: meets extreme process requirements
Scope of ultra-high temperature treatment
Some models can operate stably in high temperature environments ranging from 1200 ℃ to 1700 ℃, meeting the sintering, melting, or heat treatment requirements of high melting point materials such as special ceramics, high-temperature alloys, and semiconductor materials. For example, in the aerospace industry, the melting of high-temperature alloys relies on such equipment.

Rapid heating and precise temperature control
By using good heating elements (such as silicon molybdenum rods) and intelligent temperature control systems, the set temperature can be reached in a short period of time, and the temperature fluctuation can be maintained within ± 5 ℃. This high-precision temperature control capability ensures the repeatability of experimental conditions and improves product quality stability.

4. Atmosphere control: expanding application boundaries
Multi atmosphere environment support
Through the gas control system, inert gases (such as argon and nitrogen), oxidizing gases (such as oxygen), or reducing gases (such as hydrogen) can be introduced to meet the stringent requirements of different materials for the atmosphere. For example, in metal heat treatment, an inert atmosphere can prevent oxidation; In the chemical vapor deposition (CVD) process, a specific gas environment can promote thin film growth.

Adaptation to high vacuum environment
Some models support high vacuum environments (such as 10 ⁻ ³ Pa), effectively avoiding sample oxidation or contamination. This is important for the processing of materials with high purity requirements such as semiconductor materials and metal powders, which can greatly improve product performance.

5. Structural and operational advantages: enhancing practicality and safety
Intelligent operation simplifies the process
Equipped with PLC control and touch screen operation interface, supporting multi-stage program programming (such as 30 stage temperature rise and fall programs), achieving automated control. Users can preset experimental parameters, and the equipment automatically completes processes such as heating, insulation, and cooling, reducing the need for manual intervention.

Multiple security protection mechanisms
Equipped with safety devices such as over temperature alarm, overload protection, disconnection protection, gas leakage detection, etc., to ensure that the power or gas supply is automatically cut off when the equipment is abnormal, ensuring the safety of operators and equipment.
