Definisyon pwodwi

Annealed pure iron plates represent the pinnacle of soft magnetic materials, manufactured through precisely controlled thermal processing (>99.8% Fe) to achieve exceptional electromagnetic properties unattainable with standard cold-rolled variants. Unlike conventional cold-rolled sheets that retain work-hardened dislocation structures, annealing at 780℃±20℃under inert atmosphere triggers complete recrystallization-transforming strained grains into uniform 15-25μm microstructures equiaxed . pwosesis sa a elimine ensiste rezidyèl pandan y ap diminye coercivity a mwens pase oswa egal a 80 A/m ak ogmante pèmeyabilite a 5, 000 - 10, {{15} Pèt, dansite segondè flux, ak estabilite dimansyon anba jaden dinamik dinamik.

Remak: Custom rkwir sik (subcritical/rkristalizasyon) ki disponib pou balanse duktilite vs . pèfòmans mayetik .

Avantaj nan rkwir: Ki jan pwosesis tèmik transfòme pèfòmans

1. Recristalizasyon-kondwi amelyorasyon pwopriyete

Pandan rkwir, fè frèt-woule pi fè sibi twa chanjman faz kritik:

- Recovery (300-450 degre): rerimanite debwatman diminye rezidyèl ensiste pa 85% san yo pa chanje mòfoloji grenn .

- Recristalizasyon (550-720 degre): souch-gratis grenn nikleyè, ranplase estrikti defòme ak restore duktilite (elongasyon sote soti nan<10% to >40%).

- Grain Growth (>750 degre): kontwole coarsening optimize domèn mobilite miray, abati pèt isterez pa jiska 30% konpare ak materyèl unannealed .

2. atmosfè-kontwole decarburizasyon

Pwopriyetè nou kontinyèl rkwir anplwaye N₂-H₂ melanj (Dew Point: -45 degre) reyalize:

- rediksyon kabòn: kontni final C mwens pase oswa egal a 0 . 005%, elimine risk aje mayetik.

- Prevansyon Sifas Oksid: Oksijèn Presyon Pasyèl Kenbe anba a 10⁻²⁵ ATM, konsève sifas klere san yo pa marinated .

3. Teksti optimize

Pousantaj refwadisman pòs-anneal (15-30 degre /s) Ankouraje GOSS ({110}<001>) ak tèkstur kib, amelyore pèmeyabilite ansanm oryantasyon espesifik .

Poukisa enjenyè presize rkwir sou frèt-woule fè pi

1. Enhanced Formability: Annealed plates achieve r-values >1 . 8, pèmèt kofre gwo twou san fon-trase ak rapò rediksyon 30% san yo pa cracking kwen.

2. Pèfòmans ki estab: Decarburizasyon<0.005% C prevents magnetic aging-guaranteeing μ stability within ±3% over 10+ years.

3. Bri/Vibration Rediksyon: Estrikti grenn inifòm Koupe Magnetostriction-induit Humming nan transformateur pa 12db (a) .

4. konpatibilite soude: ekivalans kabòn ki ba (CE<0.12) permits TIG welding without HAZ embrittlement-critical for sealed shielding enclosures.

FAQs

K: Ki jan rkwir afekte rezistans korozyon?

A: Pandan ke rkwir retire rezidyèl ensiste ki akselere korozyon, fè pi toujou mande pou penti pwoteksyon (Electroless Ni, Zn-Ni) pou anviwònman imid . nou ofri pre-plake opsyon ak adezyon-pwomosyon fini ma .}

K: Èske mwen ka reyalize tou de gwo fòs ak ba -coercivity?

A: Wi-po-woule tanpèt (3-5% rediksyon post-annealing) ogmante fòs sede a 280MPA pandan w ap kenbe HC mwens pase oswa egal a 95 A/M . Ideyal pou vibre armatures .

K: Ki metòd koupe yo rekòmande?

A: waterjet (abrazif-gratis) oswa lazè fib (1-2kW N₂-Assist) anpeche kwen redi . blanch mekanik mande pou poli mouri ak mwens pase oswa egal a clearance 3μm .
