Introduction
The Large Caliber Hydrogen Reduction Furnace is designed for sample preparation of various materials under a clean environment in a reducing atmosphere. The product utilizes a annular distributed heating uniformly positioned outside a high-purity quartz vacuum chamber, ensuring high thermal efficiency, rapid heating, and excellent temperature uniformity. The protective atmosphere circulates evenly inside, with ingress and egress for optimal performance. All sealing components feature high-temperature-resistant sealing rings, and the system employs a water-cooled stainless steel sealing system, ensuring safety and reliability.
The equipment is equipped with a comprehensive touchscreen interface for automated operation and includes alarm functions for over-temperature, disconnection, and low water pressure, enhancing user safety.
Key Features of Hydrogen Reduction Furnace
1.Double-layer insulation structure with air-cooled intermediate layer;
2. High-purity Al2O3 fiber refractory insulation material, maximizing energy savings;
3.High-purity alumina coating on the refractory furnace chamber for extended lifespan;
4.High-purity quartz furnace plug facilitates the establishment of custom temperature gradients within the tube.
5.Comprehensive over-temperature, short-circuit, and rapid cooling water protection measures for worry-free safety!
6.Temperature measurement holes and observation windows are interchangeable (selectable).
