High Carbon Ferrosilicon

Metallurgical manufacturers muab ferrosilicon, siab carbon ferrosilicon, silicon -calcium alloy, ferromanganese thiab lwm yam ferroalloy khoom ntawm tus nqi zoo, thiab muaj peev xwm muab ntau yam particle loj xws li ntuj blocks, txheem blocks, granules, hmoov, thiab lwm yam raws li cov neeg muas zaub.

High -carbon ferrosilicon yog ferrosilicon nrog cov ntsiab lus carbon loj.

High-carbon ferrosilicon yog ferrosilicon nrog cov ntsiab lus carbon loj, thiab siab -carbon ferrosilicon feem ntau yog siv rau hauv steelmaking furnaces. Piv txwv li, raws li hom tshiab ntawm cov muaj zog sib xyaw deoxidizer, nws kuj tuaj yeem siv rau cov hlau dav dav, hlau alloy thiab tshwj xeeb steel tempering. Tsis tas li ntawd, raws li tus neeg saib xyuas cua sov, nws tuaj yeem hloov cov khoom siv hluav taws xob ib txwm muaj nrog tus nqi siab dua uas yuav tsum tau ua hauv converter thiab qhib hearth steelmaking. High -carbon ferrosilicon yog ib qho kev siv ntau deoxidizer nrog cov txiaj ntsig hauv qab no: tsis muaj hydrogen qhov chaw tsim tawm thaum lub sij hawm deoxidation txheej txheem, ua kom muaj kev nyab xeeb thiab kev ntseeg tau; carbon thiab silicon yog cov ntsiab lus tseem ceeb uas txiav txim siab txog kev ua haujlwm ntawm cov hlau, thiab siab -carbon ferrosilicon tsis tuaj yeem cuam tshuam nrog oxygen hauv cov hlau molten. Rau cov nyhuv deoxidation, cov pa roj carbon monoxide thiab silicon uas tsis tau oxidized kuj tuaj yeem yaj hauv cov hlau molten kom nce silicon thiab carbon, thiab ua tiav cov nyhuv tua ob tug noog nrog ib lub pob zeb. Txhawm rau kom tau txais cov hlau uas tsim nyog cov tshuaj muaj pes tsawg leeg thiab ua kom cov hlau zoo, deoxidation yuav tsum tau ua hauv steelmaking. Cov tshuaj affinity ntawm silicon thiab oxygen yog loj heev, yog li ferrosilicon yog ib tug muaj zog deoxidizer nyob rau hauv steelmaking rau nag lossis daus thiab diffusion deoxidation. Ntxiv qee qhov nyiaj ntawm silicon rau hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm hlau.

1. Ua ntej-Kev Paub Tes Ua Haujlwm

Thaum lub sij hawm ib qho kev pab txhawb nqa nrog ib tug loj ductile hlau foundry, peb ntsib ib qho teeb meem tshwm sim. Tus neeg siv tau tsom mus rau ib txhij nce silicon cov ntsiab lus thiab ntxiv ib qho kev tswj hwm ntawm cov pa roj carbon monoxide rau lawv cov hlau molten, tab sis siv cais ntxiv ntawm cov ntshiab silicon thiab graphite ua rau kev ua haujlwm tsis zoo. Nws ua rau lub sij hawm sib cais ntev dua, cov pa roj carbon tsis zoo, thiab qhov kub poob, thaum kawg cuam tshuam rau kev tsim khoom thiab batch uniformity.

Yuav kom daws tau qhov no, peb tau npaj ib qho kev daws teeb meem uas siv pebHigh Carbon Ferrosilicon (HC FeSi). Peb tau ua hauj lwm nrog lawv cov metallurgists los xam cov qib meej (piv txwv li, Si: 65-72%, C: 8-13%) uas yuav xa ob lub ntsiab lus hauv ib qho, optimized ntxiv. Peb mam li siv a"Ib -Step Alloying" raws tu qauvntawm lawv lub qhov cub hluav taws xob, kho lub sijhawm thiab txoj kev sib ntxiv kom txo qis oxidation thiab ua kom muaj txiaj ntsig zoo.

Qhov tshwm sim yog ib15% txo lub sij hawm alloying ib lub tshav kubthiab cov pa roj carbon ntau ruaj khov thiab silicon rov qab, nrog kev hloov pauv txo mus rau ± 0.15%. Qhov no txhais uachemistry ua kom pom tseeb dua, txhim kho kev siv lub tshuab hluav taws xob, thiab txo nqi tag nrho cov alloyingrau lub foundry.

Lub ntsiab lus tseem ceeb ntawm txoj kev no yog:Hauv kev ua haujlwm metallurgical, kev ua tau zoo tsis yog hais txog kev ceev xwb - nws yog hais txog kev txo cov txheej txheem sib txawv.HC FeSi tsis yog ib qho ntawm ob lub ntsiab lus xwb; nws yog ib qho cuab yeej rausimplifying complex txheej txheem thiab txhim khu kev tswj, qhov twg ncaj qha tsav tus nqi -kev ua tau zoo thiab cov khoom zoo.

2. Cov ntsiab lus thiab Scenario Elaboration

Thaum pib qhov kev sim siab, peb pom tias tsuas yog hloov mus rau HC FeSi tsis tau txais txiaj ntsig tag nrho. Cov kev xyaum uas twb muaj lawm ntawm kev ntxiv cov alloys lig nyob rau hauv kais, thaum lub slag twb tsim, coj mus rau siab dua - tshaj - xav tias silicon poob los ntawm oxidation. Cov pa roj carbon rov qab tau zoo, tab sis cov txiaj ntsig ntawm silicon yog qhov zoo tshaj plaws.

Qhov kev sib tw uas tsis tau npaj tseg no ua rau muaj kev ua haujlwm tseem ceeb:Qhov kev ua tau zoo tshaj ntawm cov khoom sib xyaw zoo li HC FeSi tau qhib tag nrho tsuas yog thaum ua ke nrog cov txheej txheem ua kom zoo paub- yuav ua li cas.Peb yuav tsum saib tshaj qhov khoom nws tus kheej. Peb qhia rau tus neeg siv los hloov kho lawv qhov kev coj ua ntxiv, qhia txog HC FeSiua ntej nyob rau hauv lub kais dej nyob rau hauv ib tug tiv thaiv txheej ntawm molten hlaukom txo slag tiv tauj. Qhov kev hloov kho yooj yim no, raws li peb cov kev paub dhau los, tau txhawb nqa lawv cov txiaj ntsig ntawm silicon tag nrho los ntawm 8%. Nws qhia peb tias peb lub luag haujlwm yog muabkev daws teeb meem, tsis yog alloys xwb, thiab tus nqi tseeb yog los ntawm kev sib koom txheej txheem kev txawj ntse.

3. Cov neeg siv khoom tiag tiag Case Reference

Ib qho piv txwv tseem ceeb yog peb lub sijhawm ntev - koom tes nrogPrecision Castings Inc. (ib lub npe rau tus neeg siv khoom tiag), tus kws tshaj lij hauv cov khoom hnyav -section ductile hlau Cheebtsam. Lawv tau tawm tsam nrog"chunky graphite" tsim nyob rau hauv lub hauv paus ntawm lawv tuab castings, ib tug defect uas hnyav heev compromised mechanical zog. Txawm hais tias muaj ntau yam tseem ceeb tau koom nrog, lawv cov kev tshawb fawb metallurgical tau qhia tiastsis sib haum thiab tsis txaus cov pa roj carbon saturation thaum lub sij hawm lig kev kho mobyog ib tug tseem ceeb pab. Lawv txoj kev siv yav dhau los ntawm kev siv ferroalloys thiab recarburizers cais ua qhov tseeb, lig -theem micro- kho qhov nyuaj thiab tsis ntseeg siab.

Peb qhov kev daws teeb meem sib koom ua ke tsom rau kev tswj cov txheej txheem:

Khoom siv:Muab cov qib tshwj xeeb ntawm High Carbon Ferrosilicon nrog nruj tswj qhov loj me (10-30mm) kom nrawm, kwv yees kev sib cais.

Txheej txheem Innovation:Siv HC FeSi li a"trimming agent" nyob rau hauv lub ladle tom qab thawj inoculation. Qhov no tau tso cai rau lawv cov neeg ua haujlwm ua kom zoo, sib xyaw ua ke rau ob qho kawg silicon thiab carbon qib nrog ib qho, nrawm ntxiv, ua kom pom kev pom zoo ua ntej casting.

Cov ntaub ntawv txhawb nqa:Muab cov kab kos tawm raws li lawv qhov tshwj xeeb steel kub thiab ladle geometry.

Qhov tshwm sim yog a30% txo qhov tshwm sim ntawm chunky graphite defectsthiab ib qho kev txhim kho nyob rau hauv uniformity ntawm tensile lub zog nyob rau hauv tuab thiab nyias seem ntawm lawv castings. Qhov no tau txhim kho kev ntseeg siab ntawm lawv cov khoom muaj txiaj ntsig zoo, txo cov nqi seem thiab rov ua haujlwm dua, thiab ua kom peb txoj haujlwm ua lawv tus khub zoo rau kev ua haujlwm zoo.
