Tso lus
Hluav taws xob hlau yog cov khoom siv ferromagnetic ua los ntawm cov hlau uas muaj qhov sib txawv ntawm silicon (Si) uas muaj li ntawm 1% txog 6.5%. Txoj kev loj hlob ntawm cov hluav taws xob steels tau coj los ntawm cov khoom siv hluav taws xob uas xav tau cov hlau uas tuaj yeem txo cov cua sov dissipation, qhov teeb meem uas ua rau lub zog txuag. Hlau tau pom tias yog qhov kev xaiv zoo tshaj plaws hauv kev lag luam tab sis nws cov impurities tsis zoo. Nws tau pom tias qhov sib ntxiv ntawm silicon nce kev tiv thaiv, txhim kho permeability, thiab txo qis hysteresis poob. Feem ntau cov khoom siv hluav taws xob muaj nyob rau hauv cov khoom siv hluav taws xob muaj txog 3.25% Si vim tias cov ntsiab lus silicon ntau dua yuav ua rau cov khoom tshwm sim dhau los ua rau txias dov. Hluav taws xob cov hlau nrog 6.5% Si muaj qhov zoo tshaj plaws sib nqus thiab cov khoom siv hluav taws xob, tab sis cov txheej txheem thermomechanical ntxiv yuav tsum tau txhawm rau txhawm rau kov yeej nws cov brittleness thiab txwv ductility.
Cov khoom siv hluav taws xob hlau
Qhov sib ntxiv ntawm silicon nyob rau hauv hlau zoo heev txhim kho lub cev lub zog ntawm hluav taws xob steels. Cov khoom siv hluav taws xob muaj cov khoom tsim nyog hauv qab no los txhawb kev tsim, faib thiab siv hluav taws xob:
High permeability - muaj peev xwm txhawb nqa magnetic teb
Tsawg magnetostriction - tsis tshua muaj siab xav nthuav lossis cog lus hauv cov teb sib nqus
High hluav taws xob resistivity - txo cov tub ntxhais poob los ntawm kev txo cov eddy tam sim no tivthaiv
Txo hysteresis poob - qis hysteresis poob txhais tau hais tias tsawg dua lub zog nyob rau hauv daim ntawv ntawm tshav kub los ntawm alternating magnetising quab yuam
Hom hluav taws xob hlau
Non-oriented tag nrho cov txheej txheem hluav taws xob hlau
Non-oriented, tag nrho cov txheej txheem hluav taws xob steel muaj qhov sib txawv ntawm silicon qib uas nyob ntawm 0.5% mus rau 3.25% Si. Nws muaj cov khoom sib nqus sib nqus hauv txhua qhov kev qhia. Hom hluav taws xob hlau no tsis xav tau cov txheej txheem recrystallisation los tsim nws cov khoom. Cov qib qis silicon alloy muab zoo dua sib nqus permeability thiab thermal conductivity. Rau cov qib siab alloy, kev ua tau zoo dua yuav tsum nyob rau hauv siab zaus, nrog kev poob qis heev. Hom no zoo heev rau cov hlau nplaum hauv cov motors, transformers, thiab hluav taws xob hauv tsev. Hom kev ua tiav no muab qhov nyuaj hauv kev xuas nrig ntaus vim ua tiav cov txheej txheem annealing. Organic coatings yog ntxiv los txhim kho lubrication hauv cov txheej txheem xuas nrig ntaus.
Non-oriented semi-processed hluav taws xob hlau
Non-oriented semi-processed hluav taws xob steels feem ntau tsis yog-silicon alloyed steel thiab yog annealed ntawm qis kub tom qab qhov kawg txias dov. Tus neeg siv kawg, txawm li cas los xij, yuav tsum tau muab qhov kawg kev ntxhov siab-relief anneal raws li daim ntawv thov steel. Lub punchability ntawm no hluav taws xob steel hom yog zoo dua li cov uas tsis yog-oriented ua tiav hom, yog li cov organic coatings tsis tas yuav tsum tau. Cov qhab-nees uas tsis yog-txhim kho ib nrab yog cov khoom tseem ceeb zoo rau cov rotors me me, stators, thiab me me fais fab transformers.
Grain-oriented hluav taws xob steel
Grain-oriented hluav taws xob steels yog tsim los ntawm hlau nrog 3% Si cov ntsiab lus nrog cov nplej taw qhia kom xa cov permeability siab thiab tsis muaj zog poob. Grain-oriented qib muaj zog crystallographic zog. Hom no dhau los ua cov txheej txheem recrystallisation uas ua rau muaj kev txhim kho cov qauv nplej uas nthuav tawm cov khoom sib nqus zoo dua hauv cov kev taw qhia dov ntawm daim ntawv. Grain-oriented steels feem ntau yog siv rau kev siv tsis-rotating, xws li transformers.
