# 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.
