A pusher furnace plate that cracks mid-run stops the whole line and destroys the parts on it. Graphite plates take heavy loads and thermal shock in pusher furnaces. This article covers five specs that cut cracking and keep the line moving.
Jiecheng Graphite (since 2003) machines pusher furnace plates to spec, and confirms grade in writing.
Five specs that cut cracking
Grade must resist thermal shock. Thickness carries the load without stress points. Edges must be dressed to stop stress cracking. The plate must sit flat to avoid point loads. And inspection confirms the plate before it runs.
· Grade — thermal shock resistance
· Thickness — sized to the load
· Edge condition — dressed to stop cracks
· Flatness — even load, no point loads
· Inspection — per-batch proof
Where pusher furnace plates are used
Pusher furnace plates carry loads through sintering and heat-treatment in a continuous line. Confirm the load, temperature and shock conditions before ordering.
· Pusher furnace sintering plates
· Continuous heat-treat carriers
· High-shock furnace trays
· Load-bearing hot-zone plates
What to specify before you buy
Send the plate size, load, temperature and shock conditions. Jiecheng Graphite machines these plates in its 3,000 m² plant and ships worldwide.
Spec | What to confirm | Why it matters |
Grade | Shock rating | Sets crack risk |
Thickness | Load size | Carries load |
Edge | Dressed | Stops cracks |
Flatness | Value | Stops point load |
Report | Dimensions | Proves plate |
Buying checklist
1. Send size, load and temperature
2. Confirm grade for thermal shock
3. Specify dressed edges and flatness
4. Agree inspection per batch
5. Freeze the plate spec
FAQ
Why does my plate crack?
Thermal shock or a raw edge; confirm grade and edge condition.
What grade resists shock best?
A shock-resistant grade rated for the cycle; confirm the value.
How do I avoid point loads?
Keep the plate flat and the load evenly spread.
Cutting cracks in service
Cracking is caught in the grade and the edge, not after the failure. Confirm the shock conditions, the grade and dressed edges before ordering. Jiecheng Graphite documents grade and edge condition on every pusher plate, so the line keeps moving without surprise failures.
· Confirm shock conditions and grade
· Check dressed edges
· Document edge condition per batch
Cracking is preventable with the right grade, thickness, edges and flatness. Jiecheng Graphite has made pusher furnace plates since 2003 and keeps the spec on file.
