Ferro silicon calcium lub luag hauj lwm hauv ntsuab steelmaking? 

Koj hnov ​​ntau txog cov hlau ntsuab hnub no, thiab tom qab ntawd ib tus neeg cuam tshuam rau hauv ferro silicon calcium raws li cov mos txwv khawv koob. Nws tsis yooj yim li ntawd. Zaj dab neeg tiag tiag tsis yog hais txog ib qho ntxiv txuag lub ntiaj teb; Nws yog hais txog yuav ua li cas qhov tshwj xeeb workhorse alloy haum rau hauv qhov tsis sib haum xeeb, cov tswv yim sib tsoo ntawm kev ua hlau nrog tsawg zog thiab pov tseg. Kuv tau pom nws siv ci ntsa iab, thiab kuv tau pom nws pov tseg vim tib neeg tsis nkag siab qhov nuance. Nws yog deoxidizer thiab desulfurizer, paub tseeb, tab sis nws cov ntawv pov thawj ntsuab los ntawm cov saw hlau uas nws ua rau hauv lub ladle.

Tshaj li qhov yooj yim deoxidation: Qhov Kev Ua Tau Zoo Tshaj

Txhua tus paub tias calcium silicon yog lub zog deoxidizer. Tab sis lub kaum sab xis ntsuab pib nrog dab tsi tshwm sim tom qab cov pa oxygen ploj mus. Los ntawm kev tsim cov ntsiab lus qis-melting-calcium aluminosilicates, nws hloov cov kev suav nrog, ua rau lawv globular thiab yooj yim rau ntab tawm. Qhov no yog qhov tseem ceeb. Cov hlau huv huv txhais tau tias tsawg dua rov ua dua, tsawg dua qhov tsis lees paub, thiab cov khoom lag luam xav tau ntau dua los ntawm tshav kub mus rau cua sov. Qhov kev kwv yees tau txo qis qhov xav tau rau kev ua haujlwm ntau dhau lossis kho ntxiv tom qab hauv kab, uas yog lub zog txuag hluav taws xob ncaj qha. Nws tsis yog glamorous, tab sis qhov kev ntseeg siab no yog lub hauv paus ntawm kev ua tau zoo, tsis tshua muaj nqi.

Kuv nco qab ib lub zeb nruab nrab uas tau tawm tsam nrog cov nozzle clogging thaum nruam nruam. Lawv tau siv cov qauv kev coj ua, tab sis lub sijhawm poob qis tau tua lawv cov txiaj ntsig thiab lub zog ntsuas ib tuj. Lawv hloov mus rau qhov sib xws, nplua-grained ferro silicon calcium los ntawm tus neeg muag khoom uas nkag siab txog qhov loj me me rau kev tawg sai-Kuv tab tom xav txog qhov kev ntseeg tau zoo li Sab hauv Mongolia Xinxin Silicon Kev Lag Luam Co., Ltd, uas muaj cov kab ua haujlwm rau qhov no. Cov xwm txheej clogging poob ntau dua 70%. Qhov ntawd yog tsawg zog siv rau kev rov ua cua sov, tsawg dua, thiab ua haujlwm zoo dua. Cov txiaj ntsig ntsuab yog ib qho byproduct ntawm kev daws qhov mob taub hau ntau lawm.

Qhov tseem ceeb yog kev sib koom ua ke. Cov calcium txhawb kev tsim cov kua sib xyaw ua ke ntawm kev kho cua sov, uas yog qhov zoo tshaj rau kev tshem tawm ntau dua li cov khoom siv. Qhov kev ua tau zoo no txhais tau ncaj qha mus rau hauv lub sijhawm tsawg thiab roj siv rau ntawm argon nplawm rau kev tshem tawm. Thaum koj txiav stirring lub sij hawm, koj txiav lub zog noj thiab kub poob. Nws yog cov kev nce qib ntxiv thoob plaws cov txheej txheem uas ntxiv rau qhov txo qis ib puag ncig ib puag ncig.

Cov teeb meem Sulfur thiab txheej txheem Shortcuts

Desulfurization yog lwm qhov mob tseem ceeb. High sulfur txhais tau tias tsis zoo ductility thiab weldability. Ib txwm sib sib zog nqus desulfurization tuaj yeem ua tau ntev, lub zog-intensive txheej txheem nyob rau hauv lub qhov cub cub. Ntawm no yog qhov twg calcium silicon qhia nws lub ntsej muag. Cov calcium muaj kev sib raug zoo rau cov leej faj, tsim cov khoom CaS uas nkag mus rau hauv cov slag los yog hloov pauv kev suav nrog.

Peb tau sim ua ib qhov project xyoo dhau los los saib seb peb puas tuaj yeem txo cov txiv qaub noj thiab lub sijhawm kho mob los ntawm leaning ntau hnyav rau ntawm ib qho tshwj xeeb formulated ferro silicon calcium nrog ntau dua calcium yield. Lub tswv yim yog kom tau cov sulfur sai dua, ua kom lub voj voog ntawm lub cub tawg. Nws ua haujlwm, tab sis tsuas yog nce mus txog qhov taw tes. Peb tau kawm txog txoj kev nyuaj uas yog tias lub hauv paus ntawm slag thiab qhov kub thiab txias tsis zoo sib xws, koj yuav xaus nrog cov teeb meem ntawm cov khoom siv refractory los ntawm cov tshuaj tiv thaiv exothermic heev. Ntsuab shortcut yuav luag raug nqi peb lub ladle hauv ob sab phlu. Nws tau qhia kuv tias cov alloys no yog cov cuab yeej, tsis yog ib qho kev daws teeb meem; lawv yuav tsum tau muab tso rau hauv tag nrho cov slag engineering xyaum.

Qhov no yog qhov uas muaj tus neeg muag khoom nrog cov khoom siv cuab yeej cuab tam tseem ceeb. Tsis yog tsuas yog muag koj xwb silicon calcium; nws yog hais txog kev nkag siab koj cov txheej txheem. Ib lub tuam txhab nrog cov cuab yeej ntsuas ua tiav, zoo li ib qho tau hais hauv Xinxin Silicon's profile, tuaj yeem txheeb xyuas qhov txiaj ntsig tiag tiag thiab tus cwj pwm ntawm lawv cov khoom hauv koj qib steel tshwj xeeb. Cov ntaub ntawv ntawd tiv thaiv cov nqi kim, lub zog-nkim missteps.

Enabling Thin Slab Casting thiab Lightweighting

Qhov no yog qhov tsis tshua pom tseeb tab sis tseem ceeb sib txuas. Ntsuab hlau tsis yog hais txog lub zeb; nws yog hais txog cov khoom kawg ntawm lub neej voj voog. Advanced high-strength steels (AHSS) rau automotive lightweighting yuav tsum tau tshwj xeeb huv huv thiab meej sulfide zoo tswj. Kev hloov kho nruj me ntsis nrog ferro silicon calcium feem ntau yog cov kauj ruam tsis sib tham kom ua tiav qhov no.

Rau nyias slab casting, uas yog inherently ntau zog-npaum li ib txwm txoj kev, cov hlau yuav tsum ntws zoo kawg nkaus. Txhua qhov seem alumina pawg lossis cov sib txuas ntse yuav ua rau tawg. Kev siv cov tshuaj calcium uas zoo ib yam, feem ntau ntawm kev txhaj tshuaj cored hlau ferro silicon calcium, yog dab tsi ua rau cov txheej txheem txaus ntshai no ruaj khov thiab siv tau. Kuv tau pom ib txoj kab uas tsim dual-theem steel rau nws pib thav ntawv qhov twg hloov mus rau ib qho kev txhim khu kev qha alloy qhov ncaj qha cuam tshuam nrog kev txo qis hauv kev cuam tshuam txog cov khoom seem. Qhov ntawd yog qhov yeej loj heev rau kev tawm los thiab kev ruaj khov.

Qhov txuas tsis ncaj ncees tab sis muaj zog: tsis muaj kev tswj hwm kev tswj hwm los ntawm cov hlau zoo li no, koj tsis tuaj yeem ntseeg siab tsim cov hlau siab tshaj plaws uas ua kom sib zog, siv roj ntau dua. Cov txiaj ntsig ntsuab yog downstream tab sis tiag tiag.

Cov Pitfalls thiab Misconceptions

Qhov yuam kev loj tshaj yog kho nws zoo li cov khoom muag. Tsis yog tag nrho ferro silicon calcium yog tsim sib npaug. Cov ntsiab lus calcium, qhov loj me, qhov sib npaug ntawm silicon thiab calcium - tag nrho cov no qhia nws cov txiaj ntsig thiab kev coj cwj pwm. Cov khoom pheej yig, tsis sib xws tuaj yeem ua rau muaj kev sib ntxiv, uas ua rau cov khoom siv khib nyiab, nce nqi, thiab tuaj yeem rov tsim teeb meem xws li reoxidation yog tias cov tshuaj tiv thaiv hnyav dhau.

Lwm qhov yuam kev yog lub sijhawm. Ntxiv nws ntxov dhau, ua ntej deoxidation zoo nrog txhuas, tsis muaj dab tsi. Calcium yuav tsuas boil. Ntxiv nws lig dhau lawm, thaum qhov kub thiab txias tau poob, ua rau tsis zoo dissolution thiab hloov pauv tsis sib xws. Koj yuav tsum tau ntaus lub qhov rais hauv txoj kev kho mob, uas yog los ntawm kev paub thiab cov ntaub ntawv zoo los ntawm koj tus kws kho mob alloy.

Kuj tseem muaj cov lus dab neeg hais txog kev daws txhua yam hauv ib qho. Ib txhia xav tias a composite deoxidizer muaj calcium silicon yuav daws tau txhua yam. Qee lub sij hawm nws ua rau cov qib txheem. Tab sis rau cov ntawv thov tseem ceeb, koj feem ntau xav tau qhov tseeb ntawm kev kho ib leeg. Qhov sib txawv ntawm cored hlau, uas Xinxin Silicon thiab lwm tus sau raws li cov khoom lag luam, tso cai rau qhov kev txiav txim siab no, txhaj tus nqi raws li qhov nws xav tau hauv lub ladle.

Saib tom ntej: Kev sib koom ua ke thiab Traceability

Lub neej yav tom ntej ntawm ntsuab steelmaking yog hais txog cov ntaub ntawv kev koom ua ke. Nws tsis txaus tsuas yog muab pov tseg rau hauv ib qho alloy. Cov kauj ruam tom ntej yog txuas cov batch tshwj xeeb ntawm ferro silicon calcium- nws cov tshuaj thiab granulometric tsom xam - mus rau qhov kawg suav nrog scan ntawm cov hlau slab. Qhov no traceability tso cai rau kev nplua-tuning, txo qhov nruab nrab cov nyiaj ntxiv thaum lav cov txiaj ntsig, txo cov khoom siv raw thiab cov txheej txheem sib txawv.

Cov neeg muag khoom yuav tsum tau koom nrog hauv qhov no. Ib tus neeg tsim khoom nrog kev tswj hwm zoo thiab kev ruaj ntseg zoo, raws li tau sau tseg hauv qee lub tuam txhab profile, yog qhov chaw rau qhov no. Lawv tuaj yeem muab cov ntaub ntawv pov thawj, cov tswv yim zoo ib yam uas cov txheej txheem txheej txheem ua haujlwm cia siab rau. Thaum koj cov ntaub ntawv raw tuaj yeem kwv yees tau, tag nrho koj cov txheej txheem ua haujlwm tau zoo dua thiab tsis siv nyiaj tsawg.

Yog li, ferro silicon calcium lub luag haujlwm? Nws yog ib tug enabler. Nws yog qhov txhim khu kev qha, ua haujlwm nyuaj ntxiv uas, thaum nkag siab thiab siv tau raug, ua rau ntau lub tswv yim ntsuab steelmaking - siab dua yield, tsawg zog-intensive theem nrab metallurgy, thiab zus tau tej cov high lightweight steels - xyaum ua tiav nyob rau hauv lub khw hauv pem teb. Nws tsis yog lub ntsiab lus-tshaj tawm, tab sis nyob rau hauv txoj cai tes, nws yog indispensable.
