Product Introduction
The KJ-T1200-S series is a mini tube furnace integrating rotation and tilting functions, specifically designed for the uniform mixing and high-temperature sintering of powders, granules, and small-sized block materials. The equipment uses a quartz tube as the working tube, and the furnace body can tilt 0-45° axially. The sample inside the tube rotates with the furnace tube at a speed of 0-54 rpm, ensuring that the material continuously tumbles and fully contacts the heat field during heating, effectively avoiding common problems in static sintering such as agglomeration, unevenness, or localized overheating.
This series offers various furnace tube diameters (Φ25/30/40/50 mm), customizable heating zone lengths (200/300 mm), a maximum temperature of 1200℃, and a continuous operating temperature ≤1100℃. The furnace chamber is insulated with high-purity alumina ceramic fiber, with a maximum heating rate of 20℃/min and a temperature control accuracy of ±1℃. The heating element is a 0Cr27Al7Mo2 resistance wire, with N-type thermocouple temperature measurement. It comes standard with a flange seal and supports vacuum or protective atmosphere (a vacuum pump or gas mixing system is required as an option). The equipment adopts a split structure for easy placement and maintenance.
Application Areas：
This equipment is particularly suitable for processes requiring uniform powder heating, anti-agglomeration, and controllable atmosphere. Typical applications include:
1. Powder Metallurgy and Metal Powder Processing
Metal Powder Reduction: Reduction sintering of iron powder, copper powder, tungsten powder, etc., under a hydrogen or decomposed ammonia atmosphere.
Alloy Powder Pre-alloying: Rotation to fully mix and simultaneously react different metal powders.
Hard Alloys: Uniform sintering of mixed powders such as tungsten carbide-cobalt.
2. Ceramics and Refractory Materials
Ceramic Powder Calcination: Pre-calcination or solid-state reaction of powders such as alumina, zirconium oxide, silicon nitride, and silicon carbide.
Refractory Raw Material Processing: Uniform heat treatment of granular materials such as magnesia and bauxite.
3. New Energy Materials
Lithium-ion Battery Cathode Materials: Rotational sintering of lithium iron phosphate and ternary material precursors to improve batch consistency.
Anode Materials: Carbon coating or graphitization of graphite and silicon-carbon composites, with rotation to prevent agglomeration.
Solid electrolytes: High-temperature synthesis of powders such as LLZO and LATP.
4. Catalysts and Chemical Engineering
Catalyst preparation: Calcination and activation of supported catalysts (such as molecular sieves and metal oxides), with rotation to ensure uniform distribution of active components.
Inorganic pigments: High-temperature calcination of titanium dioxide, iron oxide red, etc.
5. Minerals and Geology
Mineral phase transition research: Simulating high-temperature geological processes to process mineral powder or small-particle rock samples.
Tailings resource utilization: High-temperature modification of industrial waste (such as fly ash and red mud).
6. Scientific Research and Teaching
Serving as a dynamic high-temperature reaction platform for universities and research institutions to explore new powder materials and optimize sintering processes.
