Can a rotating inclined tube high-temperature furnace be used for multiple temperature zones?

The rotating inclined tube high-temperature furnace can be designed with multiple temperature zones, and the design of multiple temperature zones is one of its important technical characteristics, which can meet the temperature gradient requirements of complex processes. The following is a detailed introduction to the multi zone rotating inclined tube high-temperature furnace:

1. Principles and advantages of multi temperature zone design
Principle: Multi temperature zone design divides the furnace body into multiple independent temperature zones along the axial direction (such as feeding zone, sintering zone, cooling zone), each equipped with independent heating elements and temperature control systems, to achieve gradient temperature distribution. For example, a 1200 ℃ multi temperature zone experimental vacuum tilted rotary sintering tube furnace can be set with a gradient temperature of 300 ℃ -1200 ℃.
Advantage:
Temperature gradient control: to meet the heat treatment requirements of materials at different stages, such as obtaining suitable sintering conditions for powder particles under different temperature conditions in metal powder sintering.
Process flexibility: Different temperatures can be set at different locations based on material characteristics to achieve more complex structural transformations.
Improve production efficiency: shorten processing time and accelerate heat treatment process.
Energy efficient utilization: Avoid energy waste caused by overall overheating.

2. Application case of multi zone rotating inclined tube high-temperature furnace
Sintering of lithium battery materials: Enterprises use NCM811 positive electrode materials for sintering of lithium batteries, with multi temperature zone temperature control (preheating zone 600 ℃, sintering zone 1150 ℃, cooling zone 300 ℃) combined with argon gas protection to improve material crystallinity and cycle life.
Preparation of Graphene/Copper Composite Materials: A research team from a certain university used a multi temperature zone rotating tilted tube furnace under an argon atmosphere at 1200 ℃ to uniformly disperse graphene in a copper matrix through tilted rotation, thus preparing high thermal conductivity composite materials.
Special ceramic production: By customizing multiple temperature zones and tilting rotation functions, ceramic products with special microstructures and excellent properties are produced.

3. Technical characteristics of multi zone rotating inclined tube high-temperature furnace
Tilt angle adjustment: The furnace tube can be tilted from 0 ° to 45 ° by an electric or manual device, which facilitates the uniform movement of materials under gravity and avoids local accumulation.
Controllable rotation speed: The rotation speed is adjustable from 0.1-10rpm, allowing the material to fully flip inside the furnace, ensuring uniform heating and atmosphere contact.
High temperature control accuracy: The temperature control accuracy in each temperature zone is ± 1 ℃, and the temperature uniformity is ± 5 ℃ (at 1200 ℃). It supports custom multi-stage heating programs.
Wide compatibility of atmosphere: The vacuum degree can reach 10 ⁻ Pa, and the atmosphere flow control range is 0-500sccm, which can achieve various environmental switches such as vacuum, inert atmosphere, and reducing atmosphere.
