FerrosiliconSiv rau kev siv cov ntaub ntawv vuam feem ntau yog tsim ntawm silicon thiab hlau, thiab tej zaum yuav muaj ib qho me me ntawm cov neeg tsiv hauv nkoj loj xws li carbon, mangelese, phosphorus, thiab leej faj. Hom kev kawm qib ferrosilicon xws liferrosilicon 75(Silicon cov ntsiab lus yog kwv yees li 72% {1}}%) thiabferrosilicon 72(Silicon cov ntsiab lus yog kwv yees li 72%) tuaj yeem siv rau cov ntaub ntawv vuam. Silicon yog nws cov khoom tseem ceeb thiab ua lub luag haujlwm tseem ceeb hauv kev siv vuam. Txawv silicon cov ntsiab lus yuav cuam tshuam cov kev ua tau zoo ntawm vuam cov ntaub ntawv. Feem ntau, ferrosilicon nrog cov ntsiab lus silicon uas haum rau qhov uas tau xaiv raws li kev xav tau vuam.
Qhov loj me: thaum siv los ua cov khoom siv vuam, ferrosilicon feem ntau ua tiav rau ntau qhov sib txawv.Hmoov ferrosiliconQhov ntau thiab tsawg feem ntau muaj 40 mesh, 60 mesh, 80 mesh, 100 mesh thiab lwm yam tshwj xeeb. Ferrosilicon ntawm ntau qhov ntau thiab tsawg yog tsim nyog rau cov txheej txheem vuam sib txawv thiab cov ntaub ntawv vuam. Piv txwv li, finer ferrosilicon yog ntau dua rau kev sib cais ua ke hauv cov khoom siv vuam.
Lub luag haujlwm hauv Vuam
Deoxidizer:
Thaum lub sij hawm vuam, qhov kub kub yuav ua rau weld hlau los nkag rau hauv cov pa tawm hauv huab cua, ua rau oxides hauv weld thiab txo qhov zoo ntawm Weld. Cov silicon hauv ferrosilicon muaj kev sib txawv nrog cov pa oxygen thiab muaj peev xwm ua ke nrog cov pa oxygen, yog li tshem tawm oxygen los ntawm weld, ua si adeoxidizingLub luag haujlwm, txhim kho cov khoom siv huv thiab cov khoom siv ntawm Weld hlau, thiab txo cov khoom siv vuam tsis xws li pores thiab slag suav.
Cov nyhuv alhoying:
Silicon yog ib qho tseem ceebsib ntxaws alloyCov. Ntxiv rau nws rau lub weld hlau tuaj yeem ua ib txoj haujlwm sib dhos thiab hloov cov qauv thiab cov khoom ntawm Weld hlau. Tus nqi uas tsim nyog ntawm silicon tuaj yeem txhim kho lub zog, hardness thiab tawv ntawm weld hlau, thiab txhim kho cov kab mob weld, thiab corrosion tsis kam ntawm Weld. Piv txwv li, hauv cov vuam ntawm qee cov txiaj ntsig highoy ntawm ferrosilicon pab kom phim cov khoom ntawm Weld hlau nrog cov khoom siv Weld.
Arc stabilization nyhib:
Ntxiv cov ferrosilicon kom muaj cov ntaub ntawv vuam xws li vuam pas nrig lossis vuam hlau kuj tseem tuaj yeem ua lub luag haujlwm ua lub luag haujlwm hauv kev ruaj khov ntawm arc. Ferrosilicon tuaj yeem txhim kho kev ruaj ntseg ntawm lub vuam arc, ua kom cov vuam muag, thiab txhim kho kev sib tw ntawm kev ua haujlwm vuam thiab kev ruaj ntseg ntawm vuam zoo.
Ntau Yam Khoom
Vuam qws:
Nws yog ib hom ntaub ntawv thov ntawm Ferrosilicon hauv cov khoom siv. Ntxiv tus nqi tsim nyog ntawm ferrosilicon mus rau txheej ntawm cov pas nrig vuam, thiab yog tsim nyog rau vuam ntawm ntau cov roj carbon steels, cov hlau loj thiab lwm yam ntaub ntawv.
Vuam hlau:
Seb nws yog cov khoom siv vuam lossis flux-cored vuam hlau, ferrosilicon tuaj yeem raug ntxiv los kho nws cov kev ua tau zoo. Ntxiv cov Ferrosilicon rau cov khoom siv vuam vuam tuaj yeem hloov cov khoom sib txuas ncaj qha rau hauv Weld; Ferrosilicon nyob rau hauv flux-cored vuam hlau yog puv hauv lub vuam hlau ua ke nrog lwm cov khoom siv sib tw thaum lub sijhawm sib tw ua ke thiab cov khoom sib txawv.
Submerged arc vuam flux:
Nyob rau hauv cov txheej txheem ntawm submerged arc vuam, flux siv ua ke nrog hlau vuam. Ferrosilicon yuav siv tau ua ib qho ntawm flux, cuam tshuam nrog cov ntsiab lus hauv vuam hlau kom ua ke rau vuam hlau kom haum thiab siv lub vuam vuam loj.
