Can experimental rotary tube furnace be used for sintering experiments?

The experimental rotary tube furnace can be used for sintering experiments and has significant advantages and wide applications in sintering experiments.

1. The core requirements of sintering experiments and the adaptability of rotary tube furnaces
Temperature uniformity
The sintering experiment requires the material to be uniformly heated at high temperatures to avoid local overheating or underheating. The experimental rotary tube furnace rotates the furnace tube 360 ° to continuously roll the material during the heating process, effectively eliminating temperature gradients. For example, when sintering alumina ceramics at 1600 ℃, rotation can control the temperature difference inside the furnace within ± 5 ℃, significantly improving the density of the finished product (>98%).
atmosphere control
The sintering process often needs to be carried out in a specific atmosphere (such as inert, reducing, or oxidizing atmosphere). The rotary tube furnace is equipped with a sealing system that can introduce gases such as nitrogen, argon, and hydrogen to meet the requirements of different sintering processes. For example, in the sintering of lithium iron phosphate materials, introducing nitrogen gas can prevent oxidation and ensure the consistency of the material’s electrochemical performance.

2. The specific application of rotary tube furnace in sintering experiments
Inorganic compound sintering
The rotary tube furnace is designed specifically for sintering inorganic compounds, and through dynamic heating, the material is uniformly heated to achieve good consistency. For example, in the sintering of positive electrode materials for lithium batteries (such as LiCoO ₂), rotation can promote uniform distribution of lithium elements and improve material capacity retention (from 85% to 92%).
Powder material sintering
Powder materials are prone to uneven sintering due to differences in bulk density. The rotary tube furnace rotates to fully mix the powder, shorten the sintering time, and reduce energy consumption. For example, in ceramic powder sintering, rotation can shorten sintering time by 30% and reduce energy consumption by 20%.
Sintering of ternary materials
In the sintering of ternary materials such as NCM for lithium batteries, the rotary tube furnace can significantly improve material performance by optimizing temperature curves and atmosphere control. For example, through 30 program programming functions, the heating, constant temperature, and cooling processes can be precisely controlled, resulting in uniform grain size of the material and a 15% increase in cycle life.

3. The technical advantages of rotary tube furnace support sintering experiments
Efficient and energy-saving
Adopting high-quality ceramic fiber insulation furnace and high-quality heating elements, the heating efficiency is high and the insulation performance is strong. Some models are equipped with air cooling systems to further improve thermal efficiency, reduce surface temperature, and make the temperature field more balanced.
intelligent control
Equipped with an automated control system, it can accurately control key parameters such as temperature, atmosphere, heating rate, and insulation time. For example, through the PID intelligent controller, 50 heating and insulation curves can be set to meet different sintering process requirements.
Safe and reliable
The control panel has protection functions such as overheating, overpressure, overcurrent, disconnection, and power-off, ensuring the safety and reliability of the experimental process. In addition, the leakage protection switch and durable materials (such as cold-rolled steel plate double-layer structure shell) further enhance the safety of the equipment.

4. Practical application case of rotary tube furnace in sintering experiment
Sintering of lithium iron phosphate material
The experimental lithium iron phosphate rotary furnace significantly improves the electrochemical performance of materials through uniform heating and efficient reaction environment. For example, after optimizing the design and operating parameters of the rotary kiln, the capacity retention rate of lithium iron phosphate material can be increased from 85% to 92%.
Ceramic material sintering
In the sintering of alumina ceramics, the rotary tube furnace refines grain size and enhances material strength through dynamic heating and atmosphere control. For example, under rotational conditions, the grain size can be refined from 50 μ m to 20 μ m, and the tensile strength can be increased by 15%.
powder metallurgy sintering
In metal powder sintering, the rotary tube furnace rotates to ensure sufficient contact between powder particles and increase sintering density. For example, in iron-based powder metallurgy, rotation can increase the sintering density to 7.2g/cm ³ and hardness by 20%.
