High-cov khoom siv hlau nplaum muaj zog cia siab rau Fe-Co alloys vim tias lawv qhov sib nqus sib nqus flux ceev tshaj 2.3 T- qhov siab tshaj plaws ntawm cov khoom sib nqus mos. Qhov no tso cai rau txo qis dua 15% hauv cov tub ntxhais ntoo khaub lig- ntu ntu rau qhov muab sib nqus flux, ncaj qha ua rau cov khoom siv sib sib zog nqus. Tsis tas li ntawd, lawv qhov kub Curie siab ntawm 950℃kom ntseeg tau tias cov khoom sib nqus nyob twj ywm tsis muaj qhov tsis zoo ntawm qhov kub siab, yog li lav qhov kev ntseeg siab ntawm siab - cov khoom siv fais fab xws li aviation thiab aerospace motors.
Kev tsis sib haum xeeb tseem ceeb: Kev lag luam - tawm ntawm lub zog loj thiab cov khoom siv loj.
Cov kws tsim qauv tsim cov khoom siv siab- kawg- xws li aerospace generators, tsav motors rau lub zog tshiab, thiab siab -precision servo systems- tsis tu ncua ntsib ib qho kev sib tw tseem ceeb: yuav ua li cas thiaj li tsim tau qhov muaj zog tshaj plaws magnetic teb nyob rau hauv nruj qhov chaw thiab qhov hnyav txwv. Conventional silicon steel sheets have a saturation magnetic flux density of approximately 2.0 T, while nickel-iron Permalloy ranges from only 0.8 to 1.6 T. In applications requiring high magnetic flux density, these limitations force an increase in core size and weight, severely restricting improvements in equipment power density.
Fe-Co alloys tau tsim tshwj xeeb los daws qhov kev sib tw no. Ntawm cov hlau-raws li cov khoom sib nqus mos, cobalt yog tib lub ntsiab lus uas, thaum alloyed nrog hlau, ib txhij txhim kho cov khoom sib nqus thiab cov Curie kub. Thaum cov ntsiab lus cobalt nce mus txog 50%, Fe-Co alloys ua tiav qhov siab tshaj plaws saturation sib nqus flux ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom cov khoom siv.
Los ntawm Permendur mus rau Vacoflux 50: Tus Nqi Tsim Nyog ntawm Vanadium
Keeb kwm ntawm Fe-Co alloy txoj kev loj hlob yog qhov tseem ceeb ntawm kev hloov kho thev naus laus zis los daws qhov teeb meem ntawm "kev ua tau zoo sib nqus" thiab "kev ua tau zoo."
Txawm hais tias thaum ntxov 50Co-Fe alloys (Permendur) tau nthuav tawm cov khoom sib nqus zoo heev, lawv raug kev txom nyem los ntawm cov teeb meem engineering tseem ceeb: lawv nyuaj thiab nkig, tsis muaj peev xwm ua haujlwm txias, thiab muaj hluav taws xob tsis tshua muaj hluav taws xob (kwv yees li 7 μΩ·cm), ua rau muaj qhov loj heev -frequency.eddy tam sim no. Xyoo 1932, cov kws tshawb fawb tau tsim "2V-Permendur" los ntawm kev ntxiv txog 2% vanadium rau 50Co-Fe muaj pes tsawg leeg, yog li txhim kho kev ua tau zoo thiab nce hluav taws xob tiv thaiv. Vacoflux 50 sawv cev rau niaj hnub kev lag luam embodiment ntawm no technological trajectory.
Qhov sib ntxiv ntawm vanadium plays peb lub luag haujlwm tseem ceeb:
- Ua ntej, nws inhibits qhov kev loj hlob ntau dhau ntawm lub nkig txiav txim theem (CoFe theem), ua kom cov hlau yuav dov rau hauv nyias strips los yog stamped rau hauv cov duab nyuaj;
- Thib ob, vanadium atoms tsim ib qho kev daws teeb meem hauv matrix, ua kom cov hluav taws xob tawg thiab nce hluav taws xob tiv taus mus txog kwv yees li 40 μΩ·cm- kwv yees li tsib mus rau rau lub sij hawm ntawm CoFe alloys ntshiab - yog li txo qhov siab - zaus eddy tam sim no poob;
- Thib peb, vanadium txhim kho cov hlau ductility, tso cai rau nws los tsim cov ntawv ci li nyias li 0.1 hli lossis tsawg dua.

3. Cov yam ntxwv tseem ceeb
Hlau-cobalt (Fe-Co) alloys ua tau zoo nyob rau hauv siab- cov ntawv siv hluav taws xob ua tsaug rau peb yam tseem ceeb hauv qab no:
High Saturation Sib Nqus Flux Density
Thaum cov hlau thiab cobalt sib xyaw ua ke nyob rau hauv qhov sib piv ntawm 1: 1, cov khoom nthuav tawm Slater siab tshaj plaws -Pauling sib nqus lub sijhawm ntawm cov khoom siv hlau nplaum uas paub zoo, nrog rau qhov sib nqus sib nqus flux ntom ntom txog li 2.35 T. Qhov no sawv cev rau 20% - 30% kev txhim kho dua li cov qauv ntawm cov khoom siv sib nqus {7} lub ntsiab lus ntawm silicon{7}. txo qis thaum kis tib lub sib nqus flux.
Zoo heev sib nqus permeability thiab tsis tshua muaj coercivity
Fe-Co alloys muaj qhov tshwj xeeb zoo sib nqus permeability txawm nyob rau hauv magnetic teb zog mus txog saturation, kom ntseeg tau tias electromagnets thiab hluav taws xob motors khaws superior teb ceev thiab lub zog conversion efficiency nyob rau hauv muaj zog excitation tam sim no.
Kub Curie kub heev
Fe-Co alloys feem ntau muaj Curie kub tshaj 920℃. Lawv tuav cov khoom sib nqus ruaj khov yam tsis muaj kev sib nqus degradation, txawm tias nyob rau hauv qhov siab heev - qhov kub thiab txias ib puag ncig ntsib los ntawm aerospace generators lossis automotive traction motors.
Hom kev lag luam ntawm Vacoflux 50
Ua tsaug rau nws cov khoom sib nqus tshwj xeeb, Vacoflux 50 tau siv dav hauv kev txiav - ntug kev tsim khoom lag luam uas xav tau kev ua haujlwm nruj txog qhov loj, qhov hnyav, thiab cov lus teb zoo:
Aerospace thiab Defense Electromagnetic Systems
Qhov hnyav yog qhov tseem ceeb rau lub dav hlau onboard generators, aviation actuators, thiab UAV motors. Hloov cov pa hluav taws xob cov hlau nrog Vacoflux 50 tuaj yeem txo qhov ntim thiab qhov hnyav ntawm lub cev muaj zog thiab hloov pauv los ntawm 20% mus rau 30% thaum txhim kho kev ntseeg siab thaum lub sijhawm ua haujlwm siab - qhov siab.
Ultra-High-Speed EV/HEV Tsav Tsav
Raws li lub zog tshiab tsheb hloov mus rau ultra- kev kub ceev tshaj 20,000 RPM thiab ntau dua lub zog ceev, Vacoflux 50 feem ntau siv rau stator thiab rotor laminations. Nws ua kom siab dua qhov siab tshaj plaws torque thiab txo qis lub cev muaj zog tag nrho lub hnab ntawv qhov ntev.
Siab -Frequency Precision Solenoid Valves thiab High-Speed Fuel Injectors
Nyob rau hauv diesel siab -siab ntau- kev tsheb ciav hlau thiab kev kho mob roj tswj qhov tseeb, solenoid li qub yuav tsum qhib thiab kaw nyob rau hauv millisecond lossis txawm microsecond timeframes. Kev sib xyaw ua ke ntawm siab saturation magnetic induction thiab qis coercivity nyob rau hauv Vacoflux 50 generates immense instantaneous electromagnetic attraction, drastic txhim kho valve teb speeds.
Siab -Field Electromagnets for Medical and Scientific Research
Vacoflux 50 ua haujlwm raws li tus ncej- cov khoom siv hauv MRI tsom ncej, particle accelerator steering hlau nplaum, thiab siab -cov sensors siab, ua kom muaj zog, zoo ib yam, thiab thaj chaw sib nqus.
Cov ntsiab lus tseem ceeb rau kev yuav khoom thiab siv
Kev kho cua sov yog qhov tseem ceeb rau kev qhib kev ua haujlwm:Cov khoom sib nqus ntawm Vacoflux 50 yog cov rhiab heev rau cov txheej txheem kho cua sov. Kev kho cua sov pom zoo suav nrog tuav cov khoom ntawm 820℃rau 10 teev, tom qab ntawd txias ntawm tus nqi ntawm 100-200 K / h. Kev kho cua sov hauv qhov chaw hydrogen lossis hauv qab lub tshuab nqus tsev yog qhov tseem ceeb kom ua tiav cov khoom sib nqus zoo.
Stress Sensitivity:Vacoflux 50 muaj lub siab magnetostriction coefficient (kwv yees li 60-70 ppm), txhais tau hais tias txhua yam kev ntxhov siab cuam tshuam rau nws cov khoom sib nqus. Ntau dhau clamping quab yuam los yog dabtsi yog khoov kev nyuaj siab ntawm cov tub ntxhais yuav tsum tau zam thaum sib dhos thiab ua haujlwm; txwv tsis pub, magnetic permeability yuav txo, thiab suab nrov yuav nce.
Kev txwv ntau zaus:Vim nws tsis tshua muaj hluav taws xob tiv thaiv, Vacoflux 50 tsuas yog haum rau DC thiab tsawg- cov ntawv thov zaus (feem ntau hauv qab 400 Hz). Kev ua haujlwm hauv nruab nrab- mus rau siab- ntau zaus yuav tsum tau siv cov laminations nyias lossis lwm cov khoom siv.
Daim ntawv muab khoom
Vacoflux 50 feem ntau yog muab los ua cov khoom lag luam thiab kev cai- cov khoom zoo li tus, ua tau raws li cov qauv thoob ntiaj teb xws li IEC 60404-8-6 F11 thiab ASTM A801, nrog rau GB / T 14988 (1J22) tus qauv.
