An annealing bar that sags or warps under heat ruins the batch it carries. Graphite annealing bars support loads through annealing and heat-treat cycles. This article covers four checks that keep an annealing bar flat and long-lived.
Jiecheng Graphite (since 2003) machines annealing bars to spec, and confirms flatness in writing.
Four checks on flatness and life
Flatness supports the load evenly. Thickness carries the load without sagging. Grade sets temperature and creep resistance. And inspection confirms the bar before it reaches the furnace.
· Flatness — even load support
· Thickness — sized to the load
· Grade — rated for temperature and creep
· Inspection — per-batch proof
Where annealing bars are used
Annealing bars support loads through annealing, brazing and heat-treat cycles. Confirm the load, temperature and size before ordering.
· Annealing and heat-treat bars
· Brazing and furnace carriers
· Hot-zone support bars
What to specify before you buy
Send the bar size, load and temperature. Jiecheng Graphite machines annealing bars in its 3,000 m² Dalang plant and ships worldwide.
Check | What to confirm | Why it matters |
Flatness | Value | Controls support |
Thickness | Load size | Stops sag |
Grade | Temp + creep | Sets life |
Report | Dimensions | Proves bar |
Buying checklist
1. Send size, load and temperature
2. Specify flatness on the load face
3. Confirm grade and thickness
4. Agree inspection per batch
5. Freeze the bar spec
FAQ
Why does my bar sag?
Thickness or load too high; confirm both.
What grade resists creep?
A creep-resistant grade rated for the temperature.
How flat should it be?
Flat enough for even support; confirm the value.
Confirming bar performance
An annealing bar must carry its load without sagging. Confirm the bar size, load and temperature, and ask for flatness in writing. Jiecheng Graphite holds the flatness and thickness you specify and documents them, so the bar supports the batch evenly.
· Confirm size, load and temperature
· Set flatness on the load face
· Document thickness per batch
An annealing bar stays true when flatness, thickness, grade and inspection are confirmed. Jiecheng Graphite has made annealing bars since 2003 and keeps the spec on file.
