Dab tsi yog silicon hlau

Silicon steels are ferritic alloys of iron and silicon that have magnetic properties which make them useful in motors and transformers. The silicon additions improve magnetic softness and increase the electrical resistivity. They also have the undesirable effects of decreasing the Curie temperature, reducing the saturation magnetization, and of embrittling the alloy when the silicon additions exceed about 2 wt .% {{{{} Cov nplej zom ua ke los tsim cov nplej zom kom ntau dua li 3} kev cob qhia yog nqa tawm mus kho kom haum rau cov hlau nplaum yooj yim axis.

1. bicicon steels

Drastically zoo instrovatory kev ua tau zoo raws li kev txhim kho tshuab thiab cov khoom sib nqus tau ua tiav los ntawm cov khoom sib xyaw ua ke, yog ib qho uas tsis muaj txiaj ntsig, muaj peev xwm ua tau los ntawm cov roj ntsha li cas, yog ib qho twg los xij, tuaj yeem ua rau muaj cov khoom siv li ntxaij, thiab cov khoom siv tsis tau ua tiav, yog ib qho uas tsis tau ua tiav tus account rau kwv yees li 40% thiab 25%, feem, ntawm lub ntiaj teb kev ua lag luam rau cov ntaub ntawv sib nqus mos (coey, 2009).

2.} hlau-li alloys

Cov hlau-silicon alloys muaj txog li 4% si siv rau cov khoom siv sib nqus thiab cov tshuab hluav taws xob tsawg dua, thiab xa tawm cov kev txiav txim siab me me, thiab xa tawm cov kev txiav txim siab tsawg dua Paramount tseem ceeb .

Raws li kev tshawb fawb thiab kev tsim kho ntau xyoo, qhov zoo ntawm cov khoom lag luam uas muaj zog ntawm cov qib siab thiab ntawm kev sib tw ntawm cov khoom lag luam qis {} <.

3. Phem hluav taws xob-hlau hluavtaws

Cov khoom siv mos nyiam tshaj plaws uas siv hauv cov tshuab hluav taws xob yog silicon-hlau hluav taws xob hlau (saibCov hlau, silicon hlau raws: sib nqus cov khoom) Nyob rau hauv daim ntawv ntawm nyias lamination . Qhov ntxiv ntawm cov pob zeb hluav taws xob nrog cov khoom siv hluav taws xob hauv thaj tsam li 1-3}} 5%, thiab lis-taw-taw Anisotropic cov khoom uas muaj 2 {. 9-3 . 15% SI (+ AL). Silicon qib siab tshaj 3.5% ua rau cov hlau ua kom tawg thiab nyuaj ua haujlwm. Cov hlau ua haujlwm tau muaj qhov qis tshaj plaws poob (saib cov lus 1) thiab tau siv hauv cov tshuab hluav taws xob, cov khoom tsis muaj hluav taws xob yog siv hauv cov lus qhia zoo.

4. beadS: Kev Ntseeg

Cov hlau tsim tsim tshwj xeeb rau cov hluav taws xob tshwj xeeb, sib nqus, thiab cov khoom sib nqus, thiab cov khoom siv lub cev muaj xws li cov tshuab silicon (saibSilicon Steels), cov hlau nplaum sib nqus (saibSib Nqus Hlau) Thiab cov hlau muaj cov coefficients tsawg ntawm thermal expansion (saibSteels: kev nthuav dav tsawg).
