Tsis tshua muaj Aluminium Ferrosilicon Alloy rau huv steel ntau lawm

Tsawg aluminium ferrosilicon yog cov hlau-silicon alloy nrog tswj cov ntsiab lus txhuas, feem ntau muab ntawm cov qib silicon ntawm 72-75% thiab aluminium txwv xws li kwv yees li 0.5% mus rau qis dua, siv los ua deoxidizer thiab silicon hauv cov hlau huv si thiab tshwj xeeb - qib steel ntau lawm.

Dab tsi yog Qhov Tsawg Aluminium Ferrosilicon?

Tsawg aluminium ferrosilicon yog qib tshwj xeeb ferroalloy nyob rau hauv uas txhuas yog txhob txwm txwv kom txo qis piv nrog cov qauv lag luam ferrosilicon. Nyob rau hauv cov pa ntau lawm, txhuas nkag mus rau hauv lub alloy raws li ib tug kab ntawm silica - bearing raw cov ntaub ntawv thiab txo cov neeg ua hauj. Thaum cov qib no tau txais rau cov qauv hlau dav dav, lawv tuaj yeem ua kom tsis muaj kev tswj hwm txhuas rau hauv cov hlau da dej thaum deoxidation.

Los ntawm kev xaiv cov khoom siv raw nrog qis aluminium- bearing minerals thiab siv cov txheej txheem tswj thaum submerged -arc furnace smelting, cov neeg tsim khoom tuaj yeem muab ferrosilicon nrog cov ntsiab lus txhuas txo. Cov khoom khaws cia cov tub ntxhais hlau metallurgical muaj nuj nqi ntawm ferrosilicon- muab silicon rau deoxidation thiab alloying-thaum txo qhov xwm txheej qhia txog txhuas rau hauv cov kua hlau.

Daim ntawv thov nyob rau hauv huv thiab tshwj xeeb steel ntau lawm

Tsawg aluminium ferrosilicon tau teev tseg thaum steel kev huv thiab kev tswj hwm suav nrog ua qhov tseem ceeb tshaj tus nqi txo qis. Cov pawg steel hauv qab no yog cov ntawv thov sawv cev:

Tire Cord thiab Bead Wire Steel

Cov log tsheb thiab cov hlaws hlau yog kos rau cov kab uas hla hauv qab 0.3 hli thiab yuav tsum tau nyiaj ntau lab ntawm kev qaug zog. Ntawm qhov loj me no, txawm tias microscopic inclusions dhau los ua qhov tsis xws luag cuam tshuam rau cov hlau hla -section. Aluminium oxide suav nrog yog qhov teeb meem tshwj xeeb vim tias lawv nyuaj, angular, thiab tsis zoo deformable thaum xaim kos duab. Tsawg aluminium ferrosilicon txo ib qho ntawm kev tswj tsis tau Al₂O₃ tsim.

Caij nplooj ntoos hlav hlau

Automotive ncua kev kawm ntawv thiab valve springs ua haujlwm nyob rau hauv cyclic loading. Internal inclusions ua raws li kev ntxhov siab concentrators uas txo cov qaug zog lub neej. Kev tswj cov khoom siv aluminium los ntawm ferroalloys txhawb kev ua tiav ntawm kev suav nrog cov hom phiaj teev tseg hauv cov qauv caij nplooj ntoos hlav steel.

Bearing Steel

Rolling-cov bearings yuav tsum tau hlau nrog tshwj xeeb microstructural uniformity. Aluminium oxide suav nrog hauv thaj chaw sib cuag ntawm cov khoom dov thiab cov kev sib tw ua kom muaj kev ntxhov siab uas ua rau pitting lossis subsurface qaug zog tawg. Bearing steel cov neeg tsim khoom qhia cov khoom seem qis qis, thiab qis Al FeSi pab ua kom tau raws li qhov yuav tsum tau ua.

Cold Heading thiab Fastener Steel

Fasteners uas ua los ntawm lub taub hau txias yuav tsum deform uniformly yam tsis muaj nto los yog sab hauv tawg. Hard inclusions tsim strain incompatibility thaum tsim. Kev tswj cov khoom siv aluminium pab tswj kev ua tus cwj pwm zoo ib yam hauv cov qib txias.

Customized Chemistry thiab Ntau Lawm Flexibility

Tshaj li kev tswj hwm ntawm txhuas, lwm yam tshuaj tsis tuaj yeem hloov kho hauv ferrosilicon matrix kom ua raws li cov neeg siv khoom tshwj xeeb. Qhov no suav nrog kev tswj cov calcium, titanium, thiab carbon qib uas cov ntsiab lus tau teev tseg hauv daim ntawv cog lus yuav khoom.

Txhua lub phiaj xwm kev tsim khoom yog npaj tawm tsam cov hom phiaj ntawm chemistry. Deviations yog tswj los ntawm cov txheej txheem hloov los yog batch segregation. Cov kev cai chemistry thov raug tshuaj xyuas ua ntej kev lees paub los xyuas kom meej tias qhov kev thov muaj pes tsawg leeg tuaj yeem ua tiav nyob rau hauv ib txwm ferrosilicon smelting xyaum.

Cov ntaub ntawv zoo thiab kev soj ntsuam xyuas

Txhua qhov khoom xa tuaj yog nrog los ntawm Daim Ntawv Pov Thawj Kev Ntsuam Xyuas (COA) sau cov tshuaj muaj pes tsawg leeg ntawm cov khoom xa tuaj. COA yog tsim los ntawm cov qauv coj mus kuaj thaum lub sij hawm tsim khoom thiab kev ntim khoom zaum kawg, sim siv kev lag luam - cov txheej txheem analytical.

Cov ntaub ntawv ntxiv muaj nyob rau thaum thov suav nrog:

• Daim ntawv qhia txog kev faib khoom loj
• Kev txheeb xyuas qhov tseeb ntawm kev ntim khoom
• Thib peb-kev tshuaj ntsuam xyuas ib tog neeg (tso raws li tus neeg thov kev thov)
• Cov ntaub ntawv kev nyab xeeb thiab cov ntaub ntawv tuav

Cov neeg siv khoom xav tau cov kev sim tshwj xeeb lossis kev kuaj xyuas qhov chaw kuaj pom zoo yuav tsum hais cov cai no thaum lub sijhawm nug.

Loj, Ntim, thiab Logistics

Tsawg aluminium ferrosilicon yog nkag rau hauv cov ntaub ntawv sib xws nrog steel zeb khoom tuav tshuab:

• Lump daim ntawv: Standard lumps for manual or mechanical add to ladles and furnaces
• Qhov loj me: Crushed thiab tshuaj ntsuam rau cov kev teev tseg (piv txwv li, 10–50 mm, 10–80 mm) rau automated charging systems
• Ntim: steel drums los yog ib lub hnab ntim khoom loj; customized ntim raws li kev xav tau logistics thiab cov neeg siv khoom nyiam

Qhov loj me me thiab ntim cov lus qhia tshwj xeeb tau lees paub nyob rau theem kev nug kom ntseeg tau tias muaj kev sib raug zoo nrog cov neeg siv khoom them nqi thiab cov chaw cia khoom.
