Ferrosilicon hmoov: kev siv zoo hauv ntau lub teb

Ferrosilicon hmoov, raws li ib tug refined daim ntawv ntawmferrosilicon, leverages nws qhov chaw tshwj xeeb saum npoo thiab muaj zog reactivity kom ua tiav "kev haumxeeb haumxeeb" hauv steelmaking, casting, vuam, thiab tshuaj industries. Nws qhov loj me thiab cov kev cai muaj pes tsawg leeg txiav txim siab ncaj qha rau nws daim ntawv thov cuam tshuam, ua rau nws yog ib qho tseem ceeb uas yuav tsum tau ua kom zoo dua cov khoom siv hauv kev tsim khoom.

FeSi hmoov yog tsim los ntawm FeSi los ntawm kev sib tsoo / atomization:

Cov ntsiab lus tseem ceeb:Cov qib tseem ceebFeSi 75hmoov (Si 72% -80%, Fe 20% -28%),FeSi 70hmoov (Si 68% -75%, Fe 25% -32%), impurities Al Tsawg dua los yog sib npaug rau 1.5%, S Tsawg dua los yog sib npaug rau 0.05%, P Tsawg dua los yog sib npaug rau 0.04%;

Lub cev muaj zog:Melting point 1250-1350 degree, ntom 6.9-7.1g / cm³, qhov loj ntawm 50-400 mesh (suav nrog 300μm-38μm), qhov tshwj xeeb thaj chaw 1-5m² / g, kub reactivity 30%-50% siab dua thaiv;

Core zoo:Uniform dispersion, ceev cov tshuaj tiv thaiv ceev, meej muaj nuj nqi, haum rau refined ntau lawm xav tau kev pab, ua tiav "me me, high efficiency" deoxidation thiab alloying teebmeem;

Daim ntawv thiab ntim:Hmoov (50-400 mesh) (Mesh) thiab atomized hmoov (sphericity Ntau dua lossis sib npaug li 85%) tau ntim rau hauv cov dej noo-cov pov thawj valve hnab (25kg / hnab) lossis ton hnab. Lub tshuab nqus tsev vacuum-pov thawj kev kho mob yog xav tau rau kev thauj mus los thoob ntiaj teb.

Raws li ib tug deoxidizer

FeSi hmoov yog ntxiv rau molten hlau thaum lub sij hawm steelmaking txheej txheem. Vim muaj cov tshuaj lom neeg muaj zog ntawm silicon thiab oxygen, ferro silicon hmoov tuaj yeem hnov ​​​​mob sai sai nrog oxygen hauv cov hlau molten los tsim cov tebchaw xws li silicon dioxide. , yog li zoo txo ​​cov pa oxygen hauv cov hlau molten thiab txhim kho cov hlau zoo. Piv txwv li, thaum tsim cov qib siab - qib hlau alloy, cov nyhuv deoxidation ntawm ferrosilicon hmoov tuaj yeem tiv thaiv qhov tsis xws luag xws li qhov pores thiab looseness hauv cov hlau thiab txhim kho qhov ntom ntawm cov hlau.

Raws li tus neeg sawv cev alloying

Ferrosilicon hmoov yog pub rau hauv cov hlau molten ua ke nrog lwm cov alloys, thiab sib npaug sib npaug los ntawm kev nplawm thiab lwm txoj kev. Cov silicon tau muab tso rau hauv cov hlau, uas tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau. hmoov Ferrosilicon feem ntau yog siv los ua tus neeg sawv cev alloying thaum smelting cov qauv hlau, cov cuab yeej steel, caij nplooj ntoos hlav steel thiab silicon steel rau transformers.

Thaum lub sijhawm ua haujlwm tshwj xeeb, ntxiv ferrosilicon hmoov rau cov hlau molten thiab do tusyees sai. Nws tuaj yeem txhawb nqa nag lossis daus thiab spheroidization ntawm graphite, yog li txhim kho kev ua haujlwm ntawm cam khwb cia hlau. Piv txwv li, hauv kev tsim cov hlau ductile, ferrosilicon hmoov pab cov graphite kom sib npaug ntawm cov cam khwb cia hlau matrix nyob rau hauv cov duab kheej kheej, zoo heev txhim kho cov khoom siv ntawm cov hlau cam khwb cia, zoo heev txhim kho nws lub zog tensile, toughness thiab ductility, uas ua tau raws li cov kev xav tau ntawm kev tsim khoom, tsheb muaj lwm yam kev lag luam hlau.

Muab cov hmoov ferrosilicon nrog rau lwm cov ntaub ntawv raw khoom sib npaug los ua cov txheej txheem thiab siv rau ntawm qhov chaw ntawm lub vuam pas nrig, uas yuav pab txhim kho kev ua haujlwm ntawm vuam pas nrig, ua rau cov txheej txheem vuam ruaj khov thiab qhov vuam zoo dua.

Hauv kev lag luam ntxhia, hauv av lossis atomized ferrosilicon hmoov tuaj yeem siv los ua lub sijhawm ncua los pab txhim kho kev ua haujlwm zoo thiab raug ntawm cov ntxhia ua.

Hauv kev lag luam tshuaj, siab -silicon ferrosilicon hmoov tuaj yeem siv los tsim cov khoom siv silicone thiab lwm yam khoom, muab cov ntaub ntawv tseem ceeb rau kev tsim cov khoom siv tshuaj.
