Cov Ntsiab Lus Ferrosilicon Hmoov & Hlau Steelmaking Adjectation Cov ntsiab lus

Ferrosilicon hmoovyog ib qho kev tsis tseem ceeb ntxiv hauv cov steelmaking niaj hnub, ua haujlwm ua deoxidization, aloying tus neeg sawv cev, thiab inoculant. Nws loj (ntsuas hauv mesh) hais txog nws cov tshuaj tiv thaiv efficienty, melting ceev, thiab siv cov txheej txheem steelmaking. Ntawm cov ntau cov lus qhia tshwj xeeb, 40-300 mesh yog qhov ntau tshaj plaws ntau yam nyob hauv kev lag luam steel. Txawm li cas los xij, ntau tus neeg yuav khoom tsis sib phim nrog cov txheej txheem steelmaking, ua rau cov teeb meem steelmakaking, ua tsis tiav cov ntsiab lus nplooj, ntau dua cov khib nyiab.

Mesh Qhov loj me yog qhov taw qhia tseem ceeb ntawm ferrosilicon alloy hmoov loj, sawv cev rau cov qhib ib sab square. Qhov siab dua ntawm Mesh tus naj npawb, qhov me me, thiab hloov pauv. Rau 40-300 mesh fesi hmoov, txhua yam specification muaj cov khoom siv lub cev tshwj xeeb thiab thov kos npe. MissSelecting lub mesh qhov loj tuaj yeem cuam tshuam ncaj qha rau kev ua haujlwm loj me thiab cov khoom lag luam zoo.

1. Cov ntsiab lus tseem ceeb (40-300 mesh) thiab lawv cov yam ntxwv

Hauv qab no yog cov ncauj lus kom ntxaws tawg ntawm ib hom 40-300 mesh loj loj xws li, thiab cov yam ntxwv tseem ceeb, uas yog cov txheej txheem steelmaking:

2. Yuav ua li cas thiaj li pov thawj Mesh qhov tseeb authenticity?

Txhawm rau kom tsis txhob yuav cov khoom tsis zoo Mesh, koj tuaj yeem siv cov hauv qab no kom paub tseeb:

- Txheem Sib Tham Kev Xeem:Siv tus qauv uas muaj ntawv pov thawj los ntawm sab cib kuaj. Rau 120-mesh hmoov, tus nqi dhau los ntawm 120-mesh sieve yuav tsum muaj ntau dua los yog sib npaug rau 95%.

- laser loj acalyzer:Rau kev txiav txim siab ntau, thov kom muaj Laser loj kuaj pom ntawm tus xa khoom kom yog paub tseeb tias qhov kev faib tawm loj.

- yooj yim pom kev tshuaj ntsuam:40-60 mesh hmoov muaj pom tseeb grandularity; 250-300 Mesh hmoov zoo thiab du, nrog tsis muaj qhov pom tseeb thaum rub cov ntiv tes.

Tus yuam sij rau tus nqi -}}} Siv tau ua zoo FESI hmoov zoo rau cov txheej txheem steelmaking thiab cov khoom lag luam ". Cov txheej txheem sib txawv sib txawv (converter, hluav taws xob rauv taws) thiab cov hlau ua kom huv (pleev xim hlau, siab} qhov xav tau rau ferrosilicon hmoov mesh loj. Qhov muag tsis pom kev ua kom zoo lossis tus nqi qis yuav ua rau kev ua haujlwm pov tseg lossis kev pheej hmoo zoo.

1. Kev yoog tau mus rau cov qauv steelmaking

Qhov ntim ntawm cov ntais hlau steel, smelting kub, thiab ntxiv txoj kev ncaj qha txiav txim siab rau kev pom zoo mesh loj:

 Converter steelmaking (100-300t cov khoom siv loj):

Cov yam ntxwv: siab smelting kub (1600-1700 degree), loj molten steel ntim, batch ntxiv ntawm deoxidizers.

Zoo Mesh Qhov loj me: 40-60 mesh.
Vim li cas: coarse hais muaj tsawg ya poob (tsawg dua los yog sib npaug nrog 5%), thiab tuaj yeem ua kom tiav nrog Molten Steel thaum lub sijhawm smelting ntev. Siv cov hmoov zoo (piv txwv li, 200 mesh) yuav ua rau 15-20% poob, nce nqi.

 Hluav taws xob Rauv Stat Mivassmaking (10-50t Nruab Nrab Hluav Taws Xob Cov Hluav Taws Xob):

Cov yam ntxwv: Ua kom ntsuas qhov kub thiab txias kev tswj hwm, kev xav tau rau lub sijhawm deagidation sai.
Zoo Mesh Qhov loj me: 80-120 mesh.

Vim li cas: palanced melting ceev thiab ya poob (tsawg dua los yog sib npaug ntawm 8%), haum rau ntau qhov ntxiv thaum smelting los xyuas kom ntseeg tau tias muaj kev ruaj khov khov kho deoxidation ruaj khov.

 Tshob Refining (LF / VD / Vd Refining):

Cov yam ntxwv: Post {- smelting refinement, kev tswj hwm ntawm Alloy muaj pes tsawg leeg, qis} kev ua haujlwm kub (1500-1550 degree).
Zoo Mesh Qhov loj me: 150-200 mesh.
Vim li cas: Cov khoom zoo melt sai sai, tuaj yeem hnov ​​mob siab sai, thiab yooj yim} kub kho cov ntsiab lus ntawm silicon cov ntsiab lus.

2. Admination rau cov qauv hlau uas yuav tsum tau

Cov qhab nia sib txawv steel muaj cov ntsiab lus hnyav rau cov ntsiab lus silicon thiab kev tswj hwm tsis sib haum, xaiv mesh loj:

 Carbon Steel (piv txwv li, Q235, S235JR):

Yuav tsum muaj: Qhov yooj yim shazidation, tus nqi qis.
Zoo Mesh Qhov loj me: 40-80 mesh.
Vim li cas: coarse ntxib hmoov sib ntsib cov deagidation yooj yim xav tau, thiab tus nqi yog 10-15% qis dua cov hmoov zoo.

 Alloy Hlau (piv txwv li, 40CR, 20mnsi):

Yuav tsum muaj: meej alloying, ruaj khov silicon cov ntsiab lus (0.5-1.2%).
Zoo Mesh Qhov loj me: 80-120 mesh.
Vim li cas: Uniform particle qhov loj me ua tiav cov khoom nqus silicon (ntau dua los yog sib npaug rau 90%), zam kev sib sau ua ke.

 High - Cov Ntawv Purity Steel (piv txwv li, Cov Ntawv Automotive Automotive Hlau, Cov Kabmob Hlau):

Xav tau: Dazidation sib sib zog, qis impurities (p tsawg dua lossis sib npaug rau 0.02%, s tsawg dua lossis sib npaug rau 0.01%).
Zoo Mesh Qhov loj me: 200-300 mesh.
Vim li cas: Ultra - Cov hmoov tshwj xeeb muaj qhov loj ntawm thaj chaw thaj loj, thiab tuaj yeem tshem tawm cov oxygen thiab impurities. Nws feem ntau yog siv nrog txhuas deoxidizer rau Composite Dazidation.

3. Kev yoog tau ntxiv txoj kev

Txoj kev ferrosilicon hmoov ntxiv rau Molten hlau kuj cuam tshuam rau Mesh Qhov Loj Xaiv:

{{0- PUB NEEG (Conveyor Siv tawv):Haum rau 40-120 mesh hmoov; Coarse hais tsis yooj yim los thaiv cov feeder.

- kev txhaj tshuaj txhaj (cov cab kuj siv roj tshuab):Haum rau 150-300 mesh hmoov; Cov nplais zoo tuaj yeem yog cov neeg coob heev hauv Molten steel nrog cov cab kuj roj.

{{0-} tus phau ntawv ntxiv (me me rauv):Haum rau 80-120 mesh hmoov; yooj yim khiav lag luam thiab tswj tus nqi.

Ntawm qhov tseeb ntawm kev sib txuam ntawm Mesh cov txheej txheem, cov lus qhia steel, cov lus qhia hauv qab no tuaj yeem pab koj txuas ntxiv cov nqi thiab zam kev txaus ntshai:

1. Zam kev tshaj tawm -}} specification: tsis txhob ua kom zoo tsis tsim nyog

Tus finer lub mesh loj, cov nqi ntau lawm. Piv txwv li, 300-mesh hmoov yog 25-30% kim dua 60-mesh hmoov. Yog tias cov hlau siv roj carbon hlau yog smelted nyob rau hauv ib lub hloov pauv, siv 60-mesh hmoov tuaj yeem ua kom tau raws li qhov yuav tsum tau ua, thiab tsis tas yuav xaiv 200-ntxaij hmoov.

2. Paub meej tias kev faib tawm loj, tsis yog Mesh tooj

Tib tus naj npawb Mesh yuav muaj qhov sib txawv loj. Yuav tsum muaj cov neeg xa khoom los muab cov kev faib khoom loj me me (piv txwv li D10, D50, D90 qhov tseem ceeb). Rau 120-mesh hmoov, txoj kev zoo tshaj plaws D50 (Median loj) yog 150-180 μm, ua kom muaj kev sib txawv.

Kev yuav khoom hmoov ferrosilicon tsis yog "ib - loj {{1 {2- txhua qhov" txheej txheem. Cov tub ntxhais yog kom phim rau 40- 300 mesh} 300 mesh} 300 screatification nrog cov qauv statmaking, qib steel, thiab ntxiv txoj kev. Los ntawm kev xaiv mesh loj, koj tsis tuaj yeem tsuas yog deoxidation thiab kev sib txuam tab sis kuj txo cov nqi them tsis tseem ceeb los ntawm kev tshwj xeeb lossis poob poob.

Peb lub tuam txhab tshwj xeeb hauv kev muab 40-300 mesh ferrosilicon hmoov (72-Qib, 75-qib) Nrog ISO 9001 ntawv pov thawj.
