Ferrosiliconlumps ntawm 10-100mm yog qhov feem ntau siv loj hauv steel mills. Fesi alloy ntawm qhov loj me no nkag mus tob rau hauv cov hlau molten thaum poob rau hauv lub ladle, tsis txhob raug daig thiab hlawv los ntawm slag, ua rau muaj kev ua haujlwm siab deoxidation.

Yuav ua li cas ntxiv subdivide 10-100mm lumps?

Granularity ntau yam	Haum rau leej twg	Vim li cas
10-50 hli	Cov me me thiab nruab nrab-size steel ladles (tsawg dua lossis sib npaug li 100 tons), lossis cov ntawv thov xav tau cov lus teb sai	Nruab nrab- cov khoom me me yaj sai sai, ua rau muaj kev sib xyaw ntawm cov hlau molten.
50-100 hli	Cov hlau loj loj (Ntau dua lossis sib npaug li 100 tons), lossis cov ntawv thov nrog cov txheej slag tuab	Cov khoom loj, vim lawv qhov hnyav, tuaj yeem nkag mus rau cov txheej slag tuab thiab tog tob rau hauv cov hlau molten, txo qhov kub hnyiab -tawm.

Rau cov ladles me thiab ua haujlwm sai, siv 10-50mm lumps; Rau cov ladles loj thiab cov txheej slag tuab, siv 50-100mm lumps.

Yuav ua li cas peb thiaj li uniform loj?

Cov ntaub ntawv raw (silica, semi-coke, steel seem) yog smelted nyob rau hauv ib tug hluav taws xob arc rauv kom tau ferrosilicon lumps nrog ib tug silicon ntsiab lus ntawm 72-75%. Tsis zoo li qee cov nroj tsuag me me uas tsuas yog crushed loj ingots thiab sieve lawv, peb cov txheej txheem txheem yog raws li nram no:

Coarse Crushing:Lub puab tsaig crushers tsoo cov ingots loj kom tsawg dua lossis sib npaug li 150mm.

Sib nqus sib cais:Tshem tawm cov khoom siv hlau uas tau muab sib xyaw rau hauv lub sijhawm crushing (txo cov ntsiab lus hlau ntawm cov khoom tiav los ntawm 0.2-0.5%).

Peb-Kev tshuaj ntsuam theem:Sib cais cov ingots rau hauv 50-100mm thiab 10-50mm qhov ntau thiab tsawg siv 50mm thiab 10mm mesh cov ntxaij vab tshaus feem. Cov hmoov me dua 10mm yog rov ua dua thiab rov ua dua.

Kev soj ntsuam zaum kawg:Ib qho piv txwv raug coj los ntawm txhua 200 tons rau ICP-OES tsom xam ntawm Si, Al, Ca, Mn, Cr, P, thiab S. Batch cov ntaub ntawv xeem tau lees paub tias suav nrog cov khoom xa tuaj.

FAQ

Q: Tus nqi sib txawv ntawm 10-50mm thiab 50-100mm yog dab tsi?

A: 50-100mm daim feem ntau yog me ntsis pheej yig dua 10-50mm daim vim lawv hla cov txheej txheem crushing thiab tshuaj ntsuam. Yog tias koj lub ladle loj thiab koj tsis xav tau qhov loj me, kev yuav 50-100mm yog tus nqi ntau dua.

Q: Puas yuav loj ferrosilicon daim muaj hmoov? Kuv txhawj xeeb txog cov hmoov ntau dhau ua rau muaj pa taws thiab pov tseg.

A: Peb cov khoom loj yog tag nrho cov tshuaj ntsuam xyuas, thiab cov hmoov hmoov yog tswj tsis pub dhau 3%. Yog tias koj pom cov hmoov ntau dhau thaum koj tau txais cov khoom, koj tuaj yeem qhia rau peb, thiab peb yuav tshuaj xyuas lawv dua lwm zaus.

Q: Tus nqi sib txawv ntawm Qib A thiab Qib B yog dab tsi?

A: Qib A yog kim dua qib B, nyob ntawm kev ua lag luam. Rau zoo tib yam rebar thiab hlau pas nrig, Qib B yog txaus; rau export steel, alloy steel, los yog steel nrog nruj muaj pes tsawg leeg yuav tsum tau, Qib A yog ntau txhim khu kev qha.

Q: Puas yog qhov luaj li cas ntawm koj 10-100mm daim sib xws ntawm cov khoom siv?

A: Yog, nws yog. Peb sieve txhua batch ntawm cov khoom ua ntej lawv tawm hauv lub Hoobkas los xyuas kom meej tias ntau tshaj 90% ntawm cov khoom nyob rau hauv koj lub cheeb tsam. Yuav tsis muaj ib pawg me me sib xyaw nrog cov loj loj.
