FeSi 72%

72% ferrosilicon hmoovyog qhov tseem ceeb ntawm kev lag luam version ntawm75% ferrosilicon hmoov. Nws cov ntsiab lus silicon yog nyob nruab nrab ntawm 70% thiab 75%, me ntsis qis dua ferrosilicon75, tab sis nws kuj tseem pheej yig dua.

Cov neeg muas zaub 72% fesi feem ntau muaj ib qho kev xav: "Zoo txaus, Kuv tsis xav siv nyiaj ntau dua."

Rau refining zoo tib yam carbon steel (rebar, hlau qws):siv fesi72 rau deoxidation yog zoo txaus thiab pheej yig dua 75%.

Rau kev ua zoo tib yam castings (manhole npog, counterweights):siv fesi 72% raws li ib qho inoculant kuj ua tau thiab pheej yig dua.

Rau lwm cov ntawv thov uas cov ntsiab lus silicon tsis nruj:tsuav yog raws li cov kev cai yooj yim, 72ferrosilicon yog tus nqi tshaj plaws -kev xaiv zoo.

Dab tsi yog qhov txawv ntawm 72 ferrosilicon thiab 75 ferrosilicon?

Silicon cov ntsiab lus sib txawv:75fesi muaj cov ntsiab lus silicon ntau dua lossis sib npaug li 75%, thaum 72fesi yog nyob nruab nrab ntawm 70% thiab 75%. Yog li ntawd, thaum siv 72 ferrosilicon, tus nqi ntxiv yuav tsum tau me ntsis ntxiv kom them rau qhov sib txawv ntawm silicon.

Nqe sib txawv:ferrosilicon72 yog pheej yig dua ferrosilicon75, nyob ntawm kev ua lag luam.

Kev ua tau zoo sib txawv yog tsawg:Rau cov pa roj carbon zoo tib yam thiab cov castings zoo tib yam, tsis muaj qhov sib txawv ntawm 72 thiab 75 ferrosilicon.

Yog li, yuav xaiv li cas? Nws nyob ntawm koj qhov khoom muag:

Rau kev xa tawm steel, hlau alloy, thiab cov khoom siv nrog cov kev cai nruj nruj: siv 75 ferrosilicon rau kev ruaj ntseg.

Rau qhov zoo tib yam rebar, dav castings, thiab tus nqi- cov khoom rhiab heev: siv 72 ferrosilicon rau tus nqi-effectiveness.

Ntau lub sij hawm ntev - cov neeg siv khoom khaws ob qho tib si ntawm tes: 75 ferrosilicon rau cov kev xav tau siab thiab 72 ferrosilicon rau qis dua. Qhov no ua kom ob qho tib si zoo thiab kev tswj xyuas tus nqi.

1. Deoxidation ntawm Plain Carbon Steel (Siv loj tshaj plaws)

Steel mills tsim rebar, hlau pas nrig, lub kaum sab xis steel, thiab channel steel feem ntau yuav 72% ferrosilicon rau deoxidation.

Yuav siv li cas: Ntxiv rau lub ladle thaum tapping, 1.5-3 kg ib tuj hlau.

Vim li cas siv 72% es tsis txhob 75%: Cov pa roj carbon steel tsis tshua muaj cov ntsiab lus ntawm silicon, ua 72% pheej yig dua.

Pom zoo loj: 10-50mm lumps, yooj yim ntxiv, tsis muaj pa luam yeeb.

2. Inoculation ntawm Ordinary Castings (Grey Iron, Ductile Iron)

Foundries ua manhole npog, counterweights, thiab ua liaj ua teb machinery qhov chaw siv 72% ferrosilicon raws li ib tug inoculant.

Yuav siv li cas: Ntxiv nrog rau qhov ntws hauv lub tapping trough los yog yaug mus rau hauv qab ntawm lub ladle.

Vim li cas thiaj siv 72%: Cov castings no tsis muaj qhov yuav tsum tau ua haujlwm siab, 72% txaus, thiab cov nyiaj khaws cia tau txhais ua cov txiaj ntsig.

Pom zoo particle loj: 1-3mm los yog 3-8mm hais, ceev deoxidation.

3. Raw Materials rau Spheroidizing Agent ntau lawm

Qee cov tuam txhab spheroidizing tus neeg sawv cev yuav 72% ferrosilicon, sib tov nrog magnesium thiab tsis tshua muaj ntiaj teb cov ntsiab lus, thiab tom qab ntawd yaj nws mus rau spheroidizing cov neeg ua haujlwm. Hom kev thov no yuav tsum muaj kev ruaj ntseg ntawm cov muaj pes tsawg leeg; cov ntsiab lus silicon tsis tuaj yeem sib txawv heev los ntawm batch mus rau batch. Peb 72% ferrosilicon muaj qhov ruaj khov nyob hauv cov khoom siv, thiab ntau lub sijhawm ntev - cov neeg siv khoom tau siv nws.

4. Lwm Tus Nqis - Daim Ntawv Thov Kev Ntsuas

Piv txwv li, cov xov xwm hnyav hauv kev ua cov ntxhia, vuam flux coatings, thiab exothermic agents . 72% ferrosilicon tuaj yeem siv tau ntev npaum li qhov xav tau ntawm silicon cov ntsiab lus tsis nruj.

Q: Tus nqi sib txawv ntawm 72% thiab 75% ferrosilicon yog dab tsi?

A: 72% pheej yig dua 75% ferrosilicon. Tus nqi pes tsawg nyob ntawm kev ua lag luam, tab sis qhov sib txawv feem ntau yog ob peb puas yuan ib tuj. Cov nyiaj koj txuag los ntawm kev yuav 72% yog koj cov nyiaj tau los.

Q: Kuv tau siv 75% ferrosilicon. Yog tias kuv hloov mus rau 72%, kuv puas yuav tsum tau hloov cov qauv?

A: Koj yuav tsum tau kho nws me ntsis. Vim tias cov ntsiab lus ntawm silicon ntawm 72% yog 3-5% qis dua 75%, tus nqi ntawm ferrosilicon ntxiv yuav tsum tau nce me ntsis. Txhawm rau txiav txim siab npaum li cas, koj tuaj yeem sim me me ua ntej, sim cov ntsiab lus silicon ntawm cov khoom tiav, thiab tom qab ntawd kho nws.

Q: Koj puas tuaj yeem 72% ferrosilicon tuav cov ntsiab lus silicon ruaj khov ntawm 70% thiab 75%? Kuv txhawj xeeb tias cov batch no yuav yog 71% thiab tom ntej no 73%, nrog kev hloov pauv loj hauv kev sib xyaw.

A: Yog. Peb kuaj txhua pawg nrog lub spectrometer ua ntej nws tawm hauv lub Hoobkas kom ntseeg tau tias cov ntsiab lus silicon nyob rau hauv qhov koj xav tau, nrog kev hloov pauv hauv ± 1%. Daim ntawv tshaj tawm kev xeem suav nrog cov khoom, thiab koj tuaj yeem ua qhov kev kuaj xyuas koj tus kheej.
