Kev lag luam metallurgical tau mob siab rau kev tsim cov khoom siv, cov qauv hlau, ntawm ib hom yog hluav taws xob hlau. Nws yog feem ntau siv hauv kev tsim hluav taws xob thiab hluav taws xob cov qauv thiab qhov chaw.
hluav taws xob hlau
Hluav taws xob cov hlau yog cov khoom siv uas sib txawv yog tsim los rau cov kev xav tau ntawm kev lag luam hluav taws xob thiab hluav taws xob. Cov khoom zoo li cov hlau no ua kom cov haujlwm du thiab txhim kho lub neej ntawm cov khoom siv los ntawm nws.
silicon hlau
Hom hlau no yog cov khoom siv hlau nplaum tseem ceeb rau kev siv loj. Hauv cov hlau, silicon muaj nyob hauv ntau qhov sib txawv. Nyob ntawm tus nqi ntawm cov khoom sib nqus xav tau. Ua tsaug rau cov silicone, qhov kev tiv thaiv ntawm cov hlau nce, lub zog quab yuam txo qis thiab hysteresis poob kuj tseem txo qis.
Yog tias silicon muaj 5 feem pua lossis ntau dua, cov khoom siv kho tshuab deteriorate heev: brittleness thiab hnyav nce. Cov hlau ntawd tsis pub stamping.
hlau ntshiab
Cov hlau ntshiab yog suav tias yog cov hlau uas muaj cov ntsiab lus carbon sib npaug los yog tsawg dua 0.02 feem pua. Nws technically belongs rau hluav taws xob hlau, thiab yog ib yam khoom hu ua magnetically muaj zog. Nuclei, electromagnets, ncej pieces thiab roj teeb daim hlau yog tsim los ntawm nws.
Technically, cov hlau ntshiab yog suav tias yog cov pa roj carbon tsawg, nrog cov ntsiab lus carbon txog li 0.05 feem pua. Yog hais tias nws muaj lwm yam impurities tshaj li tsawg kawg. Cov hlau no tau txais los ntawm cov zaub mov ntshiab. Cov khoom sib nqus nyob ntawm seb muaj pes tsawg tus impurities nws muaj.
Hom steel Ntau lawm tshuab cuam tshuam rau cov khoom kawg. Raws li qhov no, hluav taws xob hlau yog: Txias dov nrog cov ntsiab lus silicon ntawm 3.3 feem pua, uas tau muab faib ua isotropic thiab anisotropic. Kub dov - isotropic, silicon cov ntsiab lus yog 4.5 feem pua.
Silicon cuam tshuam li cas cov khoom sib nqus ntawm cov hlau?
Nyob rau hauv lub xeev cov khoom, silicon dissolves nyob rau hauv hlau ntawm kub txog li 800C. Lub solubility yog 15 feem pua hauv qhov xwm txheej no. Cov alloys uas muaj txog li 2.5 feem pua silicon muaj thaj tsam uas nthuav dav nrog cov ntsiab lus carbon ntxiv.
Ntawm lawv yog qib 1212 thiab 2011 ntawm hluav taws xob hlau, thiab lwm yam. Silicon yog tib lub ntsiab lus uas ua rau kom cov hlau nplaum permeability ntawm hlau thiab nws cov hluav taws xob tsis kam. Qhov no kuj tseem yuav txo qis kev yaum, uas txhais tau tias txo qis los ntawm kev thim rov qab magnetization. Hlau casting tshuab yog tsim los tsim cov impurities tsawg dua nrog cov nyiaj txaus ntawm silicon hauv cov khoom kawg.
Daim ntawv thov steel phaj Kev lag luam tsim cov phaj uas ncav cuag qhov dav ntawm {{0}} hli, qhov ntev ntawm 720-2000 hli thiab thickness ntawm 0,1 mus rau 1.0 hli.
Tsis tas li ntawd, nws tsim cov kab nqaim {{0}}, 15-1,0 mm tuab. Cov khoom ntawm cov ntawv hlau ua rau nws zoo tagnrho rau kev siv hauv kev lag luam hluav taws xob. Cov no yog lub siab, sib nqus loops, chokes, rotors thiab stators rau dynamos, relays, hluav taws xob motors, stabilizers, tam sim no transformers thiab ntau ntxiv. Feem ntau, textured steel yog siv vim nws cov khoom sib nqus tseem ceeb dua.
Kev Siv Hluav Taws Xob Hlau
Kev lag luam tsim cov nplooj ntawv uas ncav cuag qhov dav ntawm {{0}} hli, qhov ntev ntawm 720-2000 hli thiab tuab ntawm 0,1 txog 1,0 hli. Ntxiv mus, nqaim bands 0, 15 - 1,0 mm tuab yog tsim.
Cov khoom ntawm cov ntawv hlau ua rau nws haum rau siv hauv electronics. Nrog nws, cores, sib nqus circuits, shocks, rotors thiab stators yog tsim rau dynamos, relays, hluav taws xob motors, stabilizers, tam sim no transformers thiab ntau ntxiv.
magnetic tub ntxhais
Ib hom khoom siv yog lub phaj lossis daim kab xev, uas yog, lub tshuab hloov pauv yog tsim los ntawm ib tus neeg cov khoom. Lawv hu ua shields thiab rods, raws li cov duab ntawm daim hlau uas cov hlau nplaum cores mounted.
Cov yam ntxwv uas qhia txog hom khaub thuas dov grain oriented anisotropic hlau yog siv nyob rau hauv hluav taws xob steel daim kab xev sib nqus circuits. Txiav magnetic cores yog tsim los ua kom winding zoo dua.
hluav taws xob steel tub ntxhais
Cov ntawv hlau thib ob yog siv los tsim cov stator thiab rotor cores uas muab cov tshuab hluav taws xob uas ua haujlwm nrog cov hloov pauv tam sim no. Hluav taws xob steel tub ntxhais yog siv nyob rau hauv lub hwj chim transformers. Rau nws cov khoom siv, xws li cov hlau tsis muaj hlau yog siv, uas muaj cov khoom ruaj khov.
Hlau yog txawv nyob rau hauv cov nqe lus ntawm nws cov tshuaj muaj pes tsawg leeg. Tab sis nws cov khoom sib nqus tom qab tua hluav taws, uas yog nqa tawm ntawm qhov kub ntawm 950C thiab tsis muaj oxygen, thiab tom qab txias ntawm qhov kub ntawm 600C rau 10 teev yuav tsum tsis txhob tsawg tshaj li cov qauv tsim.
