Description :
The Z-LX continuous non-metallic rotary furnace is an industrial dynamic calcination equipment independently developed by Shaanxi Gangzheng Kiln Technology Co., Ltd., specifically designed for heat treatment of high-purity materials.
Its core technology lies in the use of non-metallic inner liners, which can achieve continuous, precise temperature control, and controlled atmosphere production. The following will provide a detailed introduction to the working principle, core technological advantages, main applications, and performance parameters.
1、 Working principle and process
The device adopts a combination of dynamic rotation and spiral propulsion for heat treatment:
- Dynamic operation: The furnace body rotates at a low speed (such as 0.03-0.15 revolutions per minute) and maintains a small tilt angle (about 1 °), allowing the materials inside the furnace to continuously and dynamically move forward.
- Material movement: The furnace tube is equipped with a spiral structure inside. Under the combined action of slow rotation and tilting of the furnace body, the material rolls forward, ensuring that each material can be uniformly heated and in contact with the reaction atmosphere, effectively avoiding the common local overburning or "entrapment" phenomenon in traditional static furnaces.
- Precise temperature control: The equipment adopts a circular external heating method and can be configured with multiple independent heating zones to achieve temperature gradient control in different stages such as preheating, constant temperature, and cooling in complex processes.
2、 Core technological advantages
Compared to traditional rotary furnaces, the core competitiveness of the GZ-LX series is mainly reflected in the following four aspects:
- High purity guarantee: Non metallic inner liner eliminates pollution, which is the biggest highlight of this series. The furnace tube is made of non-metallic materials such as quartz ceramic, high-purity alumina, or silicon carbide/nitride, which fundamentally avoids the pollution of materials caused by metal ion migration. When processing high-end lithium battery materials, the magnetic substance content can be controlled below 0.01ppm, significantly better than metal furnace tubes (0.1ppm).
- High precision control: Intelligent temperature control and atmosphere management achieve precise temperature control of ± 1 ℃ through PLC and PID algorithm. The surface temperature rise of the furnace can be controlled below 50 ℃, ensuring the stability of the process and consistency of the product. The equipment is compatible with various process atmospheres such as nitrogen, argon, hydrogen, and oxygen, and can achieve precise gas concentration control of ± 2% through a mass flow meter (MFC).
- High efficiency and low consumption: Energy saving and cost reduction, excellent performance. Advanced insulation materials such as aluminum silicate fiber modules and double-layer air cooling system are used, effectively reducing heat loss and energy consumption by more than 70% compared to traditional static furnaces. The furnace tube material itself has better thermal conductivity and can increase thermal efficiency by over 30%.
- Stable and durable: The combination structure of labyrinth seal and spring compression seal is used for excellent sealing and corrosion resistance, ensuring extremely low leakage rate during dynamic operation and stable process atmosphere. The non-metallic inner liner has excellent resistance to corrosive media such as hydrofluoric acid and strong alkali, and its service life can usually reach 2-3 times that of metal furnace tubes.
