2. Application Background
A lithium battery material sintering pusher kiln typically consists of a fully sealed furnace body, transition chamber, piping, hydraulic system, feeding control, temperature control and heating systems, and is used for the mass production of LFP, NCA and graphite anode materials.
In continuous sintering, the kiln has many temperature zones and long running hours. Heating power control directly affects temperature profile stability, sintering consistency and line continuity. The heating system therefore needs properly sized single-phase or three-phase SCR power controllers for each zone and load circuit.
3. Requirements & Technical Challenges
For this application, the heating and power control system had to address the following points:
- Multi-zone sectional control: Pusher kilns contain multiple heating zones that require independent power regulation and temperature control.
- Continuous production stability: Sintering cycles are long, so the power controllers must withstand long-term continuous operation.
- Mixed single-phase and three-phase loads: Different heating circuits coexist on site, requiring APR3 three-phase and ST200 single-phase units to work together.
- Stable temperature profile: The sintering process imposes strict ramp, soak and cooling requirements; the controllers must deliver smooth, reliable output.
- Site integration: The controllers must coordinate with feeding, temperature control, heating and automation systems.
4. KULUN Solution
Kulun Electric configured APR3 three-phase SCR power controllers (100–350 A) and ST200 single-phase SCR power controllers (75–150 A) for the pusher kilns, matched to the three-phase and single-phase electric heating circuits on site.
The solution works with the kiln feeding, temperature control and heating systems to deliver stable multi-zone power regulation, providing a reliable heating control foundation for continuous sintering of cathode and anode materials.
Key Features of the Solution
- Combined single/three-phase fit. APR3 serves three-phase heating circuits and ST200 serves single-phase circuits, adapting to different kiln zones and load configurations.
- Wide current coverage. APR3 covers 100–350 A and ST200 covers 75–150 A, allowing flexible selection by heating circuit capacity.
- Smooth, controllable output. Heating power is regulated by the temperature control system setpoint, reducing temperature fluctuation and improving process stability.
- Built for continuous production. Designed for long-cycle lithium material sintering, meeting continuous kiln operation and multi-zone control requirements.
- Easy system integration. Works with temperature controllers, PLC, feeding control and heating systems for automated kiln temperature control.
- Industrial reliability. Meets continuous operation, cooling, electrical protection and anti-interference requirements of lithium material production sites.

9. FAQ
Can APR3 and ST200 be used in lithium battery material sintering pusher kilns?
Yes. The APR3 three-phase SCR power controller suits three-phase heating circuits and the ST200 single-phase unit suits single-phase circuits; both are used for multi-zone heating control in sintering pusher kilns.
Why does a pusher kiln need SCR power controllers?
A pusher kiln must control heating power per zone according to the process profile. SCR power controllers regulate output from the temperature control signal, helping keep sintering temperatures stable.
How to select between APR3 100–350 A and ST200 75–150 A?
Selection is generally based on load phases, rated current, heating power, number of zones and control mode. Use the APR3 series for three-phase circuits and the ST200 series for single-phase circuits.
What parameters are needed to specify controllers for lithium material sintering?
Typically input voltage, load power, load type, single or three phase, number of zones, current rating, control signal, cooling method, installation space and site environment.
Can Kulun configure heating control solutions for lithium material sintering lines?
Yes. Kulun Electric can configure APR3, ST200 and other SCR power controller solutions according to the zone count, load capacity, control mode and installation conditions of pusher kilns, roller kilns and heat treatment furnaces.
