Hlau ntshiab?
Cov hlau ntshiab yog qhov tseem ceeb hlau nrog cov impurities tsawg, feem ntau carbon, phosphorus, thiab leej faj. Thaum nws yog theoretically nyuaj kom ua tiav 1 0 0% ntshiab cov txheej txheem tau qhib cov hlau ua kom zoo nkauj nrog cov qib huv huv. Muaj cov hlau ntshiab, feem ntau hu ua ib hom hlau, feem ntau muaj hlau nyob rau hauv ntau yam ntawm 99.95%, nrog cov pa roj carbon (500% thiab cov nyiaj tsawg.
Kev nthuav dav ntshiab hlau
Ua kom sov cov hlau ntshiab, tseem muaj cov hlau ntshiab lossis hlau ua kom huv, yog tsim los ntawm kev ua kom zoo dua uas tshem tawm cov hlau lossis hlau ore. Cov txheej txheem no tuaj yeem koom nrog melting cov hlau hauv lub cub tawg thiab siv ntau hom kev sib cais los cais cov khoom sib cais thiab lwm yam tsis xav tau. Cov hlau tshwm sim muaj cov pa roj carbon ntau thiab txo qib phosphorus, leej faj, thiab lwm yam impurities, ua rau nws xav tau kev ua haujlwm siab thiab tawv.
Kev sib xyaw ntawm cov cua sov cov hlau
Qhov muaj pes tsawg leeg ntawm cov hluav taws ntshiab ntshiab tuaj yeem sib txawv me ntsis nyob ntawm cov txheej txheem ua kom zoo dua thiab cov khoom siv raw. Txawm li cas los xij, nws feem ntau muaj:
Hlau (FE): 99.90% {2}}. 95%
Cov pa roj carbon (c): tsawg dua 0. 002%
Lwm cov ntsiab lus: Tsawg tus nqi ntawm silicon (si), manganese (mn), phosphorus (p), leej faj (thiab lwm yam kab kawm.
Electromagnetic ntshiab hlau hlau
Electromagnetic ntshiab cov hlau ntshiab, ntawm qhov tod tes, yog hom tshwj xeeb tsim rau cov ntawv thov cov khoom siv sib nqus zoo. Nws feem ntau yog siv nyob rau hauv cov khoom siv hluav taws xob, xws li transformer cores, solenoids, thiab sib nqus. Electromagnetic ntshiab xim hlau yog cov cim los ntawm nws cov hlau nplaum qis, ua kom zoo tagnrho rau kev hloov hluav taws xob muaj txiaj ntsig zoo hauv kev sib nqus.
Kev sib xyaw ntawm electromagnetic ntshiab hlau hlau
Electromagnetic dawb huv Hlau yog tsim nrog txoj hlua nruj tswj tau nws cov tshuaj lom neeg ua kom ua tau zoo rau nws cov kev ua haujlwm sib nqus. Nws feem ntau muaj:
Hlau (FE): tshaj 99.8%
Cov pa roj carbon (c): tsawg dua 0. 002%
Silicon (si): mus txog 0. 01%
Manganese (MN): Mus txog 0. 20%
Phosphorus (p) thiab Sulphur (s): tsawg dua 0. 004% txhua
Aluminium (Al): Ntxiv rau hauv cov nyiaj me me (txog {0. 05%}.
Qhov sib txawv tseem ceeb ntawm cov cua ntshiab hlau thiab electromagnetic ntshiab hlau
1. Muaj pes tsawg leeg
Qhov sib txawv tshaj plaws ntawm cov cua ntshiab hlau thiab electromagnetic ntshiab hlau ua lus nyob hauv lawv cov tshuaj lom neeg muaj pes tsawg leeg. Thaum ob hom hlau muaj cov ntsiab lus muaj roj carbon ntau, hluav taws xob ntshiab tau tswj hwm nyob rau theem ntawm cov neeg tsis huv, thiab cov pa roj carbon ntau, kom ntseeg tau tias qhov kev ua tau zoo. Tsis tas li ntawd, electromagetic ntshiab cov hlau feem ntau muaj cov ntsiab lus alloy, xws li txhuas, kom txhim kho nws cov khoom sib nqus.
2. Cov Txheej Txheem Ntau Lawm
Cov txheej txheem ntau lawm rau ua kom cov hlau ntshiab huv thiab hluav taws xob hluav taws xob ntshiab kuj sib txawv. Kev nthuav dav cov hlau ntshiab feem ntau yog tsim los ntawm cov txheej txheem ua kom zoo nkauj los ntawm cov hlau ua kom zoo nkauj lossis hluav taws xob ua kom zoo nkauj, kom ua tiav qhov kev xav tau huv thiab muaj pes tsawg leeg.
3. Kev thov
Kev ua kom sov huv huv cov hlau muaj txiaj ntsig rau nws txoj kev ua siab loj thiab tawv, ua kom cov tshuab ua kom muaj zog thiab cov khoom siv hluav taws xob, thiab cov khoom siv. In contrast, Electromagnetic Pure Iron is primarily used in applications that demand superior magnetic properties, such as electrical transformers, electric motors, and magnetic sensors.
Hauv cov ntsiab lus, cua ntshiab cov hlau thiab electromicetic ntshiab cov hlau yog ob qho tib si zoo nkauj ntawm cov hlau nrog cov khoom sib txawv thiab cov khoom. Ua kom sov cov hlau yog tus cwj pwm los ntawm nws cov siab siab thiab tawv, thaum hluav taws xob ua kom zoo rau cov khoom lag luam zoo tshaj plaws. Nkag siab cov kev sib txawv no yog qhov tseem ceeb rau cov tuam ntxhab thiab cov neeg yuav khoom nrhiav cov hom ntshiab feem ntau rau lawv cov ntawv thov tshwj xeeb. Raws li cov khoom siv ntshiab hlau tsim, nws yog qhov tseem ceeb kom sib txuas lus rau koj cov neeg siv khoom txawv kom lawv tau txiav txim siab txiav txim siab rau lawv cov kev xav tau.
