Sliding Tube Furnace

The Sliding Tube Furnace, an innovative device tailored for high-temperature heat treatment and rapid cooling, stands out with its unique features. It boasts a high-purity alumina polycrystalline fiber furnace chamber, domestically produced high-quality resistance wire (with an option for Swedish Kanthal A1 imported resistance wire), and a maximum temperature of 1200°C. This furnace supports low vacuum, positive pressure, and inert atmospheres (N₂, CO₂, Ar), making it a versatile solution for various industries and research experiments.

This furnace model adopts a double-layer shell structure and a 30-segment programmable intelligent control system, combined with phase-shift triggering and thyristor control, achieving temperature control accuracy of ±1°C, uniform temperature distribution, fast heating/cooling rates, and energy efficiency. Suitable for laboratory research and small-scale production in universities, research institutes, and industrial enterprises, particularly for high-temperature atmosphere sintering, atmosphere reduction, chemical vapour deposition (CVD), and vacuum annealing processes.

CVSIC Sliding Tube Furnace Application

The Sliding Tube Furnace is widely used in the following industries and processes:

• Lithium-ion battery materials: sintering and rapid cooling of cathode and anode materials.
• Ceramic industry: sintering and heat treatment of special ceramics and functional ceramics.
• Research and laboratories: heat treatment experiments on new materials (such as nanomaterials and composite materials) in universities and research institutions.
• Atmosphere reduction: reduction of metal oxides and chemical reaction experiments.
• Brazing and CVD: high-precision brazing and chemical vapour deposition (CVD) processes.
• Vacuum annealing: Annealing treatment of metal and alloy materials.

This furnace type provides an ideal solution for customers requiring rapid cooling, precise atmosphere control, and high-efficiency thermal processing, particularly suitable for laboratory research and small-scale production.

CVSIC Sliding Tube Furnace Advantages

The Sliding Tube Furnace, featuring advanced technology and user-centric design, offers the following core advantages:

• Rapid cooling: Sliding furnace tube design facilitates rapid cooling of samples, enhancing experimental efficiency.
• Precise Temperature Control: 30-segment programmable PID control combined with phase-shift triggering and thyristor control, achieving temperature accuracy of ±1°C and uniform temperature distribution.
• High-Durability Furnace Chamber: Alumina polycrystalline fibre furnace chamber with low thermal conductivity, high-temperature resistance, and corrosion resistance, ensuring long-term stability.
• Flexible Atmosphere Control: Supports low vacuum, positive pressure (≤0.02 MPa), and inert atmospheres (N₂, CO₂, Ar), with gas flow ≤200 SCCM, protecting the furnace tube.
• Safety Protection: Equipped with over-temperature, leakage protection, and pressure monitoring. Automatically vents when pressure exceeds 0.02 MPa to prevent furnace tube rupture or flange failure.
• Energy-saving design: A double-layer shell structure with low surface temperature and rapid heating and cooling functionality reduces energy consumption.
• High-quality heating elements: Domestic high-quality resistance wire (optional Swedish Kanthal A1 imported resistance wire), ensuring uniform heating and extended lifespan.
• Standard accessories: These include tube plugs, thermocouples, furnace tubes, vacuum pumps, vacuum flanges, and vacuum pressure gauges, simplifying operational procedures.
