Equipped with a high-definition touch control panel, the parameter settings are intuitive and convenient, supporting data recording, USB/Wi Fi export, facilitating process traceability and optimization, effectively improving process repeatability, avoiding the increase in product defect rate caused by manual operation errors, especially suitable for new material production and scientific research experiments that require high process accuracy. Some models also support remote monitoring function, which can achieve real-time viewing of device operating status and parameter adjustment, further improving operational convenience.

c. Continuous rotating operation, dual improvement of production efficiency and uniformity
Compared with traditional intermittent tube furnaces, the intelligent temperature controlled continuous rotary tube furnace adopts a working mode of "continuous feeding and continuous discharging". The furnace tube is driven by a motor and reducer system to achieve 360 ° low-speed rotation (adjustable speed from 0-10rpm), allowing the material to continuously roll and scatter inside the tube, avoiding problems such as accumulation, agglomeration, local overheating, or uneven heating. This dynamic heating method allows each material to uniformly contact the temperature field, with a higher heating area than traditional tube furnaces. The temperature difference is controlled within ± 5 ℃, greatly improving product consistency and qualification rate. The equipment can operate continuously for 24 hours without the need for repeated heating, cooling, loading, and unloading, greatly shortening the production cycle and increasing unit time output. It is particularly suitable for large-scale and large-scale powder and granular material heat treatment, while reducing manual operation costs and improving production stability.

d. Multiple protections, combining durability and safety
The intelligent temperature control continuous rotary tube furnace focuses on durability and safety in its structural design. The furnace body adopts a double-layer furnace shell and fan cooling design, with a low shell temperature to avoid operator burns; The rotating sealing part adopts a wear-resistant and high-temperature resistant sealing structure, which ensures stable operation, low failure rate, and extends the service life of the equipment. In terms of safety protection, it is equipped with multiple functions such as over temperature alarm, break protection, leakage protection, atmosphere interlock protection, emergency stop protection, etc., which can monitor the equipment operation status in real time. Once an abnormality occurs, it will immediately stop the machine and give an alarm, effectively avoiding production safety risks and ensuring workshop production safety. At the same time, the device supports electric adjustment of tilt angle (0 ° -30 °), which can optimize the material flow path and adapt to the processing needs of materials with different particle sizes.
