Selection guides
Roller hearth vs. pusher furnaces: selection for zirconia and LFP
Compare transport, loading and thermal requirements before selecting a furnace.
What determines furnace selection?
ZYGK roller-hearth and ZYTK pusher furnaces use different ways to move a load through the heating zones. Selection begins with the material, its container and the required thermal cycle.
Roller hearth: check the load and container
A roller hearth carries the load on driven rollers. Powders may still need saggers or other supports. Check roller spacing, container geometry, loading weight and the required transport speed together.
Pusher: check the plates and push cycle
A pusher furnace advances loads on supporting plates. Plate dimensions, layout and the pushing cycle affect line capacity. Heating-element and lining selections must match the actual operating temperature.
How to interpret catalog temperatures
The ZYGK catalog lists a maximum temperature of 1350 °C and a working temperature of 1280 °C for the published configurations. These values are not universal ratings for every customized furnace.
What to share for a technical comparison
For zirconia or lithium iron phosphate, provide the temperature curve, atmosphere, batch loading and throughput target. ZKR’s engineering team can then compare suitable transport arrangements and prepare a project-specific proposal.
