Ib txwm75 ferrosilicon hlauFeem ntau muaj 1% -2% txhuas, thaum peb cov khoom tswj cov ntsiab lus txhuas rau plaub theem: 0.3%, 0.5%, 0.8%, thiab 1.0%.

Vim li cas thiaj nqis peev nyiaj rau kev txo qis aluminium? Vim tias aluminium ntawv alumina suav nrog hauv cov hlau. Cov kev suav nrog no nyuaj thiab nkig, ua rau peb qhov teeb meem:

Stamping tawg:Qhov no yog qhov kev txhawj xeeb loj tshaj plaws rau cov neeg siv khoom ua automotive steel ntawv.

Txo qaug zog lub neej:Qhov no yog ib qho kev txhawj xeeb loj rau cov neeg muas zaub ua lub caij nplooj ntoos hlav steel thiab bearing steel.

Nruam casting nozzle blockage:Alumina tuaj yeem ua raws li phab ntsa sab hauv ntawm lub nozzle thaum lub sij hawm casting, ua rau muaj kev cuam tshuam kev cuam tshuam.

Yog li ntawd, yog tias koj tab tom tsim cov qib steel uas yuav tsum tau muaj siab purity (automotive steel ntawv, hluav taws xob steel, caij nplooj ntoos hlav steel, bearing steel), koj yuav tsum tau siv.qis aluminium ferrosilicon.

Peb faib cov qis al ferrosilicon rau plaub qib raws li cov ntsiab lus ntawm txhuas. Koj tuaj yeem pom cov kev cai txhuas rau koj qib steel kom phim:

Al 0.3:Cov ntsiab lus txhuas tsawg dua lossis sib npaug li 0.3%. Qhov no yog qib siab tshaj plaws, tshwj xeeb tshaj yog rau cov hlau hluav taws xob (silicon steel) thiab automotive IF steel. Hom hlau no tsis tshua muaj siab rau cov ntsiab lus txhuas; ntau tshaj 0.01% tuaj yeem ua rau nws siv tsis tau.

Al 0.5:Cov ntsiab lus txhuas tsawg dua lossis sib npaug li 0.5%. Cov qib no feem ntau yog siv los ntawm cov neeg siv khoom ua automotive DP steel, TRIP steel, thiab pipeline steel.

Al 0.8:Cov ntsiab lus txhuas tsawg dua lossis sib npaug li 0.8%. Qib no yog txaus rau cov neeg muas zaub ua lub caij nplooj ntoos hlav steel, bearing steel, thiab pwm steel.

Al 1.0:Cov ntsiab lus txhuas tsawg dua lossis sib npaug li 1.0%. Qib no yog siv los ntawm cov neeg siv khoom ua cov hlau zoo tib yam thiab cov hlau tsis tshua muaj hlau; nws yog huv dua li qub ferrosilicon thiab tsis kim heev.

FeSi75 Tsawg Al Khoom nta

1. Tsis muaj kev tawg thaum lub sij hawm stamping

Ib tus neeg siv khoom uas tsim cov ntawv hlau automotive tau ntsib ntau zaus thaum lub sij hawm stamping siv cov ferrosilicon zoo tib yam (Al 1.5%). Tom qab peb tau hais kom hloov mus rau Al 0.5%, qhov seem seem poob los ntawm 30%. Cov neeg siv khoom tom qab xa tag nrho lawv cov xaj rau peb.

2. Kev txuag hluav taws xob

Ib tus neeg siv khoom tsim hluav taws xob transformer cores muaj qhov xav tau siab heev rau cov khoom sib nqus ntawm silicon steel. Qhov me me ntawm txhuas nyob rau hauv zoo tib yam fesi alloy cov ntaub ntawv alumina inclusions ntawm grain ciam teb, ua rau hlau poob (nkim hluav taws xob). Hloov mus rau Al 0.3 txo cov hlau poob los ntawm 15%, txhim kho lub zog ntawm kev ntsuas hluav taws xob.

3. Nruam Casting

Clogged nozzles nyob rau hauv nruam casting yog ib qho mob taub hau rau ntau steel mills. Tus neeg ua txhaum yog alumina. Siv qis al fesi tuaj yeem txuas lub neej nozzle los ntawm 30% -50%, txo tus naj npawb ntawm cov nozzle hloov thiab tso cai rau ntau cov cua sov ntawm cov hlau kom raug cam.

4. Cov khoom ruaj khov

Ordinary ferrosilicon, vim nws cov txheej txheem smelting crude, nthuav tawm qhov hloov pauv loj hauv cov ntsiab lus txhuas ntawm cov khoom siv. Peb cov khoom siv hluav taws xob qis qis muaj cov ntsiab lus txhuas hloov pauv hauv ± 0.05% hauv txhua pawg, yog li koj tsis tas yuav hloov cov mis txhua hnub.

FAQ

Q: Tus nqi sib txawv ntawm Al 0.3, 0.5, 0.8, thiab 1.0 yog dab tsi?

A: Qhov qis dua cov ntsiab lus ntawm aluminium, ntau dua cov nqi tsim khoom thiab nws kim dua. Al 0.3 tseem kim dua Al 1.0. Yog li ntawd, ua ntej yuav, thov ua tib zoo xav txog: dab tsi txhuas cov ntsiab lus koj xav tau rau koj qib steel? Tsis txhob nkim nyiaj.

Q: Koj puas tuaj yeem tswj hwm Al 0.3 cov ntsiab lus hauv qab 0.3%? Kuv txhawj xeeb tias qhov batch no yuav yog 0.25% thiab tom ntej no 0.35%.

A: Yog. Peb kuaj txhua pawg nrog lub spectrometer ua ntej xa zaub mov kom ntseeg tau tias cov ntsiab lus txhuas nyob hauv qhov koj xav tau, nrog kev hloov pauv hauv ± 0.05%. Daim ntawv tshaj tawm kev xeem muaj nrog rau kev xa khoom. Cov neeg siv khoom tsim tsheb thiab hluav taws xob hlau muaj qhov xav tau siab tshaj plaws rau kev ruaj ntseg batch, thiab peb tau ua haujlwm ntau yam tsis muaj teeb meem.

Q: Kuv puas tuaj yeem yuav Al 0.2?

A: Customization yog ua tau, tab sis tus nqi yuav siab dua, thiab lub sij hawm xa tuaj yuav ntev dua. Cov neeg siv khoom feem ntau pom Al 0.3 txaus. Yog tias koj cov hlau muaj cov kev cai tshwj xeeb rau cov ntsiab lus txhuas (xws li siab -kawg hluav taws xob hlau), peb tuaj yeem ua ib pawg tshwj xeeb.
