1. What is a high-temperature continuous rotating tube furnace? Inert gas protected powder calcination furnace
The high-temperature continuous rotating tube furnace is an intelligent heat treatment equipment that integrates high-temperature heating, furnace tube rotation, continuous feeding, and atmosphere protection. The equipment furnace tube can rotate continuously at a constant speed, and with adjustable tilt angle, it can achieve automatic rolling, continuous feeding, and continuous discharging of powder materials; Simultaneously introducing inert gases such as nitrogen and argon to create a sealed oxygen free environment inside the furnace tube, effectively preventing problems such as oxidation, agglomeration, discoloration, and component deterioration of the powder during high-temperature calcination. It is a specialized equipment for powder calcination at a professional level.

2. Core advantages of equipment
a. Continuous production significantly improves efficiency
Different from traditional intermittent tube furnaces, this equipment can achieve continuous and uninterrupted feeding and discharging without the need for frequent manual start stop loading. It is suitable for large-scale powder production, greatly saving labor time and improving overall production capacity.
b. Rotating heating of furnace tubes ensures more uniform heating of materials
The furnace tube rotates at a constant speed and is equipped with a built-in lifting structure. The powder material is constantly stirred and mixed, avoiding common problems such as local high temperature, uneven heating, and sintering agglomeration. The consistency of the entire batch of material calcination is high, and the quality of the finished product is more stable.
c. Inert gas protection throughout the process to prevent high-temperature oxidation
It can be connected to inert gases such as nitrogen and argon, supports micro positive pressure atmosphere and vacuum pre pumping configuration, isolates air and water vapor, and meets the requirements of calcination, sintering, and reduction processes for easily oxidizable, volatile, and high-purity powders.
d. Wide high-temperature range, suitable for multiple types of materials
The device has a wide temperature range coverage and can achieve high temperatures of 1200 ℃, 1400 ℃, and 1600 ℃. It is equipped with high durability heating elements such as silicon carbon rods and silicon molybdenum rods, with fast heating speed and stable temperature field. It is suitable for processing various inorganic powders, battery materials, ceramic powders, and catalyst raw materials.
e. Intelligent program temperature control, process can be stored
Equipped with a high-precision PID intelligent temperature control system, it supports multi-stage temperature rise and fall program settings, can store multiple sets of production process curves, can be called with one click, and does not require repeated parameter debugging, making it easy for beginners to operate.
f. Complete energy-saving, environmental protection, safety and protection measures
Using high-quality high-purity alumina fiber ceramic insulation material, with good insulation effect, low surface temperature rise, and significant energy savings; Equipped with multiple safety features such as over temperature alarm, power-off protection, atmosphere leakage protection, and power-off when opening the door, it ensures safe and reliable long-term continuous operation.
