GNEE Hluav Taws Xob Hlau

Manufacturing txheej txheem ntawm hluav taws xob steel
Cov txheej txheem refining, melting thiab dov ntawm cov hlau yog zoo ib yam li cov carbon hlau. Txawm li cas los xij, kev tswj xyuas kom zoo dua yog xav tau ntawm txhua theem ntawm kev tsim khoom. Lub sij hawm hluav taws xob yog hais txog kev siv cov hlau, tsis yog txoj kev siv hauv melting nws. Qee cov nroj tsuag siv hluav taws xob rauv kom yaj cov hlau no, thiab cov txheej txheem tsim khoom niaj hnub xws li nruam nruam thiab argon oxygen decarburization (AOD) pab kom zoo ib yam.
Hluav taws xob hlaucov phaj yog dov rau hauv tuab gauge coils ntawm qhov kub thiab txias. Tom qab ntawd cov coils yog pickled kom tshem tawm nplai. Cov khoom yog txias dov nyob rau hauv cov roj rau zaum kawg specifications thiab annealed.Grain-oriented hluav taws xob steelyog txias txo thiab ua tiav ntau yam txheej txheem ua haujlwm uas tseem ceeb rau kev txhim kho nws txoj kev nyiam cov nplej.

Kev sib xyaw ntawm cov hlau hluav taws xob
Flat dov hluav taws xob steel yog tsim los ua kom tau raws li kev sib nqus kev ua tau zoo dua li cov tshuaj lom neeg tshwj xeeb. Magnetism yog qhov tseem ceeb tshaj plaws thiab nyob ntawm kev ua thiab tshuaj muaj pes tsawg leeg. Txawm li cas los xij, txhawm rau txhawm rau qhia cov hom ntawm cov ntaub ntawv tseem ceeb thiab qhia txog seb lawv feem ntau yog cais raws li lawv cov muaj pes tsawg leeg, cov tshuaj tshuaj ntsuam xyuas ntawm qee cov ntaub ntawv no tau teev tseg.
Silicon yog lub ntsiab alloying hauv hluav taws xob hlau. Nws yog ntxiv vim nws ua rau kom lub ntim resistivity ntawm cov hlau, yog li txo cov eddy tam sim no tivthaiv ntawm core poob. Silicon yog qhov ua tau zoo hauv qhov no ntau dua li lwm cov khoom uas tuaj yeem yooj yim ntxiv. Silicon muaj qhov txiaj ntsig ntxiv ntawm kev txhim kho cov tub ntxhais poob rau qee qhov los ntawm kev txo qis cov khoom lag luam hauv cov hluav taws xob uas tsis yog taw qhia vim nws cuam tshuam rau cov qauv ntawm cov hlau. Tsis tas li ntawd, ib theem ntawm silicon yuav tsum tau khaws cia kom tsis txhob muaj kev hloov pauv theem, yog li pab cov txheej txheem siv lead ua nyob rau hauv grain-oriented hluav taws xob hlau.
Nyob ntawm seb hom khoom, lwm yam tseem ceeb alloying ntsiab ntxiv rau hluav taws xob hlau yog txhuas thiab manganese. Txhua qhov no feem ntau yog ntxiv rau cov nyiaj tsawg dua 1.0%, feem ntau ntawm 0.1% thiab 0.5%. Cov ntsiab lus no tau ntxiv feem ntau rau lawv cov teebmeem metallurgical es tsis yog rau ib qho kev cuam tshuam lub cev xws li ntim resistivity. Lawv kuj muaj txiaj ntsig zoo ntawm cov qauv nplej ntawm cov hlau, yog li pab txo qis hysteresis tivthaiv ntawm cov tub ntxhais poob.
Lwm cov ntsiab lus muaj nyob rau hauv hluav taws xob hlau, tab sis tseem ceeb impurities thiab tsuas yog nyob rau hauv seem seem. Carbon yog ib yam khoom uas nws cov ntsiab lus sib txawv ntawm tus nqi tam sim no nyob rau hauv lub yaj mus rau tus nqi tam sim no nyob rau hauv cov khoom kawg. Kev kho cua sov tshwj xeeb yog nqa tawm thaum lub sij hawm dov zeb ua kom txo tau cov pa roj carbon ntsiab lus ntawm cov khoom ua tiav rau cov nqi qis heev. Qhov kev tshem tawm carbon no tshwm sim thaum cov neeg siv khoom annealing ntawm cov qib semi-machined.
Nyob rau hauv cov ntaub ntawv ntawmgrain-oriented hluav taws xob steel, impurities xws li sulfur thiab nitrogen yog thawj zaug yuav tsum tau los pab tsim qhov kawg siv lead ua orientation, tab sis cov ntsiab lus tom qab raug tshem tawm thaum lub sij hawm kawg anneal. Vim tias qhov sib nqus zoo ntawm cov hlau hluav taws xob yog kev ua haujlwm ntawm kev tshuaj ntsuam xyuas thiab kev ua cov zeb, tej zaum yuav muaj qee qhov sib tshooj hauv cov qib, raws li qhia hauv Table 2. Txawm li cas los xij, cov tub ntxhais poob feem ntau sib txawv nrog cov ntsiab lus ntawm silicon, thiab cov silicon nce qib tseem ceeb poob tab sis tau txais txiaj ntsig. nyob rau hauv ib tug txo nyob rau hauv siab induced permeability.
