Taw qhia
Silicon steel, ib qho tseem ceeb ntawm cov khoom siv hlau nplaum, tau tsim nws tus kheej ua tus neeg tseem ceeb hauv kev siv niaj hnub no. Raws li kev ua haujlwm me me hauv cov relays thiab mem tes transformers mus rau loj-scale siv nyob rau hauv generators, motors, thiab transformers, silicon steel tseem loj hlob nyob rau hauv qhov tseem ceeb. Nws txoj kev saws me nyuam tau raug tsav los ntawm kev xav tau kev siv hluav taws xob ntau dua thiab cov khoom siv me me uas muaj zog.
Silicon Steel: Ib Txoj Kev Taug Kev Evolutionary
Thawj cov khoom sib nqus mos, hlau, tuaj nrog nws cov khoom tsis huv. Txawm li cas los xij, raws li kev tshawb pom ntawm silicon ntxiv, muaj kev txhim kho hauv kev tiv thaiv, txo qis hysteresis poob, nce permeability, thiab ze-tag nrho tshem tawm ntawm kev laus. Niaj hnub no, peb pom ntau yam ntawm kev taw qhia silicon steel feem ntau nyob rau hauv lub hwj chim thiab faib transformers. Tab sis qhov ntawd tsis ua rau cov hlau tsis-oriented silicon tsis tseem ceeb. Non-oriented silicon steel pom nws qhov kev siv dav hauv qhov chaw uas tsis muaj nqi, cov khoom poob qis yog qhov tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv cov khoom sib hloov.
Cov khoom tseem ceeb ntawm Silicon Steels
1. Kev tiv thaiv
Nyob rau hauv kev sib piv rau hlau, silicon steel qhia tau hais tias ib tug tseem ceeb nce nyob rau hauv resistivity. Qhov kev nce no txo cov tub ntxhais poob los ntawm kev txo cov eddy tam sim no tivthaiv, yog li txhim kho lub zog efficiency.
2. Saturation Induction
Cov qib uas silicon hlau tuaj yeem sib nqus tau, lossis nws cov saturation induction, yog lwm yam khoom tseem ceeb. Qhov siab dua cov ntsiab lus ntawm silicon, qhov qis dua qhov saturation induction. Nws yog ib qho kev ntsuas ntsuas ntawm kev tswj kom muaj kev tiv thaiv siab thiab ua kom muaj kev txaus txaus saturation induction.
3. Magneto-crystalline Anisotropy thiab Magnetostriction
Cov khoom no cuam tshuam li cas cov khoom coj tus cwj pwm nyob rau hauv kev cuam tshuam ntawm magnetic teb thiab mechanical stress, ntsig txog. Thaum nce cov ntsiab lus silicon txo qis magnetostriction, kev ua haujlwm yuav nyuaj dua.
4. Curie Kub
Curie kub, uas yog siab heev rau hlau, yuav txo tau los ntawm alloying ntsiab. Txawm li cas los xij, qhov txo qis tsis cuam tshuam rau cov neeg siv silicon steel.
