Product Introduction

The furnace uses a polycrystalline mullite fiber furnace lining, which has low thermal conductivity, high strength, and excellent heat preservation and energy-saving effects. The furnace roof is a reinforced composite structure, ensuring it will not collapse even after long-term use. This series of box furnaces is a specialized piece of equipment developed for laboratories in universities and research institutes, as well as industrial and mining enterprises, for the sintering, melting, and analysis of metals, non-metals, and other compound materials.

- RT-1850℃

- Capacity 1~1000L

- Heating elements: HRE iron-chromium-aluminum resistance wire, U-shaped silicon carbide rod, U-shaped silicon molybdenum rod, etc.

- Top-opening and side-opening doors can be customized to keep the operator away from the heat source

- Intelligent 50-segment programmable automatic control

- Over-temperature alarm function

- Double-layer air-cooling structure; cooling fans ensure the outer shell temperature remains below 60℃

Application

Box furnaces is also known as muffle furnaces or box-type resistance furnaces are common high-temperature heating equipment used in laboratories and industries. They feature precise temperature control, good heat preservation, and ease of operation. They are widely used in laboratories of universities and research institutes, as well as in industrial and mining enterprises, for sintering, melting, and analytical testing of sample products. Main application areas include:

- Sintering and melting of oxide ceramics and glass materials

- Heat treatment of metals and alloys

- Synthesis of functional materials: such as high-temperature solid-state reactions of ferrites, piezoelectric ceramics, phosphors, and catalysts

- Analytical testing: ablation, thermal decomposition, oxidation, phase transformation, thermodynamic and kinetic experiments, etc.
