What processes can be used for a rotating inclined tube high-temperature furnace?

The rotating inclined tube high-temperature furnace, with its unique dynamic heating and atmosphere control technology, can complete high-precision processes such as powder metallurgy sintering, ceramic densification, catalyst activation, nano material synthesis, and new energy material processing, as follows:

1. Powder metallurgy and metal material technology
Sintering of refractory metal powder
High temperature sintering of refractory metal powders such as tungsten and molybdenum under vacuum or inert atmosphere (such as argon). The rotating tilt design ensures uniform heating of the powder, avoiding oxidation, while eliminating capillary forces between particles through dynamic rolling, preventing agglomeration, and improving material density.
Hot pressing sintering of metal based composite materials
By tilting and rotating, uniform mixing and densification of Al SiC and other metal based composite powders can be achieved. For example, in the preparation of titanium alloy composite materials, dynamic heating can promote interfacial bonding and improve material mechanical properties.
High temperature alloy sintering
Sintering high-temperature alloy powders such as nickel based and cobalt based at 1400 ℃. The tilted rotation mode improves the densification efficiency of materials and eliminates the common “onion ring” layered defects in traditional equipment.

2. Ceramic and glass material technology
Densification and sintering of ceramic powder
Control the grain growth of ceramic powders such as alumina and zirconia. Multi zone temperature control technology can achieve gradient heating (such as preheating at 600 ℃, sintering at 1200 ℃, and cooling at 800 ℃), optimizing material density and mechanical strength.
Annealing of glass products
Eliminate internal stress in glass products, improve transparency and stability. The inclined design facilitates continuous annealing of glass tubes or glass fibers, avoiding cracking.
Ceramic glaze treatment
Optimize the surface properties of ceramic products, such as glossiness and hardness, through dynamic heating.

3. Catalysis and Nanomaterial Technology
High temperature sintering of catalyst support
Control the porosity and specific surface area of catalyst carriers such as honeycomb ceramics. For example, in the preparation of platinum/alumina catalysts, the rotating tilt design can promote the uniform distribution of active components and improve catalytic efficiency.
Agglomeration control of nano powder sintering
Under the condition of dynamic rotation, the adhesion of zinc oxide, titanium dioxide and other nano powder particles can be avoided. By adjusting the rotation speed (such as 5-12rpm) and tilt angle (such as 15-30 degrees), uniform dispersion of nanoparticles can be achieved.
Nanomaterial synthesis
By precisely controlling temperature, atmosphere, and sintering time, nano ceramics and nano metals with specific morphology, size, and properties can be prepared. For example, when synthesizing graphene in a rotary tilt furnace, the number of layers and defect density can be controlled.

4. New energy material technology
Sintering of lithium-ion battery materials
Sintering ternary materials, lithium iron phosphate and other positive electrode materials under multi temperature control and inert atmosphere. For example, using a gradient temperature control of 600 ℃ in the preheating zone, 1150 ℃ in the sintering zone, and 300 ℃ in the cooling zone, combined with argon protection, can improve the crystallinity and cycle life of the material.
Reduction sintering of hydrogen fuel cell catalyst
Preparation of highly active Pt/C catalyst in a hydrogen atmosphere. The rotating tilt design promotes sufficient contact between hydrogen and catalyst precursor, improving reduction efficiency.
Solid state battery electrolyte sintering
Sintering sulfide or oxide solid electrolytes at high temperatures. Dynamic heating can eliminate grain boundary stress and improve ion conductivity.

5. Electronic and Semiconductor Materials Technology
Semiconductor wafer annealing
Eliminate wafer defects and improve material purity in a vacuum or inert atmosphere. For example, in silicon wafer annealing, uniform heating is achieved through tilted rotation design to avoid warping caused by thermal stress.
Sintering of Silicon Carbide (SiC) Coating
Optimize coating structure to enhance device performance. Dynamic heating can promote the interface bonding between the coating and the substrate, reducing cracks.
Densification and sintering of electronic ceramics
Control the grain growth and density of electronic ceramics such as alumina and zirconia. For example, in the preparation of multilayer ceramic capacitors (MLCC), the rotation tilt design can enhance the interlayer bonding strength.

6. Chemical raw material heat treatment process
Synthesis of Polymer Materials
Realize polymerization and modification of polymer materials in a specific atmosphere. For example, in polyimide synthesis, the reaction rate is controlled by dynamic heating to improve the uniformity of molecular weight distribution.
Chemical raw material reaction
Improve the purity and reactivity of chemical raw materials. For example, in the dehydration reaction of aluminum hydroxide gel, the rotary tilt design can promote the escape of water vapor and avoid caking caused by local overheating.
