Cov Khoom Txhais

Annealed pure iron plates represent the pinnacle of soft magnetic materials, manufactured through precisely controlled thermal processing (>99.8% FE) kom ua tiav cov khoom siv hluav taws xob tshwj xeeb hauv hluav taws xob hauv hluav taws xob uas tsis tau ua haujlwm nrog cov qauv mob khaub thuas-rolliants. Tsis zoo li cov nplooj ntawv txias-dov uas khaws cov khoom siv tsis sib xws Cov txheej txheem no tshem tawm cov kev ntxhov siab tam sim no thaum txo cov hlaue beels kom tsawg dua los yog sib npaug rau 5, {{14} μh \/ m. Qhov tshwm sim yog ib qho khoom siv uas tsis haum rau cov ntawv thov thov kom muaj qhov tsis txaus ntseeg, thiab qhov seem ruaj khov nyob rau hauv cov sib nqus hlau sib nqus.

Kev Tshaj Tawm Annealing: Yuav Ua Li Cas Thermal Ua Hloov Ua Haujlwm

1. Recrystallization-Tsav Khoom Ua Si

Thaum annealing, txias-dov hlau ntshiab undergoes peb qhov tseem ceeb theem kev hloov pauv:

- Rov qab (300-450 degree): dislocation carrangement txo cov kev ntxhov siab los ntawm 85% yam tsis muaj kev hloov pauv morphologology.

- Recrystallization (550-720 Degree): Lim-Dawb nplej Nucleate Nucleate, hloov deformed qauv thiab rov kho dua lub dov (elongation jumps los ntawm<10% to >40%).

- Grain Growth (>750 Qib): tswj hwm coarsening ua kom zoo Domain Phab Ntsa Mus Khelity, Slashing Hysteres ua los ntawm txog 30% piv rau cov khoom tsis muaj.

2. Cov huab cua-tswj cov decarburized decarburization

Peb cov tswv cuab tam sim no txoj kev ua haujlwm n₂-h₂ sib xyaw ua ke (dew) -45} degree) kom ua tiav:

- Kev txo cov carbon: zaum kawg c cov ntsiab lus tsawg dua lossis sib npaug ntawm 0. 005%, tshem tawm cov kev pheej hmoo laus.

- Cov kev tiv thaiv Oxide Oxide: Cov pa oxygen ib nrab ntawm hauv qab no 10 smath, khaws cia ci ntsa iab yam tsis muaj pickling.

3. Kev ntxhib los mos optimization

Tom qab-annaling txias cov nqi (15-30 degree \/ s) txhawb cov ntawv pom zoo tias cov uas pom pom tseeb ({110}<001>) Thiab cov xim kaum sab hauv, txhim kho kev sib txig sib luag nrog cov kev qhia tshwj xeeb.

Vim li cas cov tshuab tshuab qhia cov annealed dhau txias-rolled hlau ntshiab

1. Enhanced Formability: Annealed plates achieve r-values >1.8, ua kom muaj kev sib sib zog nqus cov ntsiab lus sib sib zog nqus nrog 30% kev sib cais txo uas tsis muaj ntug kev tawg.

2. Cov kev ua tau ruaj khov: Decarburization rau<0.005% C prevents magnetic aging-guaranteeing μ stability within ±3% over 10+ years.

3. Suab \/ Kev co txo qis: Uniform graphet qauv txiav cov hlauetosTosTosTosTostriant-inducing humming hauv transformers los ntawm 12dB (a).

4. VUAM sib xyaw ua ke: Tsawg Carbon sib npaug (CE<0.12) permits TIG welding without HAZ embrittlement-critical for sealed shielding enclosures.

Cov Lus Nug

Q: Annealing cuam tshuam rau corrosion tsis kam?

A: Thaum Annealing tshem tawm cov kev txhawj xeeb uas ceev nrawm, cov hlau ntshiab tseem yuav tsum muaj kev tiv thaiv kev tiv thaiv (hluav taws xob ni, zn-ni) rau cov puag ncig huab cua. Peb muab cov kev xaiv ua ntej nrog cov nplaum-txhawb nqa matte tiav.

Q: Kuv puas tuaj yeem ua tiav ob lub zog siab thiab kev sib tw qis?

A: Yog-daim tawv-dov tempers (3-5% txo cov post-anrealing) nce tawm lub zog rau lub zog rau 280mpa thaum tswj HC tsawg dua los yog sib npaug 95 a \/ m. Qhov zoo tagnrho rau vibrating armatures.

Q: Qhov kev pom zoo txiav txim dab tsi?

A: Waterjet (abrasive-dawb) lossis fiber ntau laser (1-2kw n₂-pab) tiv thaiv kev ua kom tawv. Kev dawb huv daim pam nyias muaj nyias tuag nrog tsawg dua lossis sib npaug ntawm 3μm kev tshem tawm.
