Silica Calcium Cored Hlau VS Aluminium Calcium Cored Hlau

 

Kev Sib Tham Zoo Tshaj Plaws: Silica-Calcium vs. Aluminium-Calcium Cored Hlau
Nyob rau hauv lub ntiaj teb no ntawm ob metallurgy, nrhiav kom huv si, muaj zog dua, thiab tus nqi ntau dua - steel zoo yog relentless. Ob tug titans feem ntau sawv ntawm qhov chaw ntawm qhov kev sib ntaus sib tua no:Silica{0}}Calcium (SiCa) Cored HlauthiabAluminium -Calcium (AlCa) Cored Hlau. Ob leeg yog cov muaj zog deoxidizers thiab suav nrog kev hloov pauv, tab sis lawv nyob deb ntawm kev sib hloov.
Xaiv qhov yog tsis yog hais txog chemistry; nws yog hais txog optimizing koj tag nrho cov txheej txheem steelmaking rau kev ua tau zoo thiab profitability. Cia peb rhuav tshem qhov sib txawv tseem ceeb los pab koj txiav txim siab paub.

1. Chemistry & Mechanism of Action

Ntawm lawv cov tub ntxhais, ob lub xov hlau ua haujlwm los ntawm kev txhaj tshuaj reactive rau hauv cov hlau molten da dej ntawm cov hlau sheath. Txawm li cas los xij, lawv cov cwj pwm tshuaj lom neeg thiab cov txiaj ntsig tshwm sim yog qhov sib txawv.
Silica-Calcium (SiCa) Cored Hlau:
Kev sib xyaw:Feem ntau Silicon (Si) thiab Calcium (Ca), nrog rau me me ntawm Hlau.
Mechanism:SiCa ua raws li lub zog deoxidizer, siv cov pa oxygen sai sai hauv cov yaj. Qhov tseem ceeb tshaj, cov calcium uas ruaj khov, siab - melting- cov ntsiab lus sib xyaw nrog sulfur (ua CaS) thiab oxygen (ua CaO-Al₂O₃ lossis zoo sib xws spinels). Qhov no ua rau muaj kev phom sij, qis- melting- cov ntsiab lus suav nrog hauv lub ntiaj teb, tsis muaj teeb meem uas ntab tawm yooj yim.
Cov txiaj ntsig tseem ceeb:​ Nws muab ob qho kev ua haujlwm -deoxidation thiab kev hloov kho- hauv ib pob, ua haujlwm tau zoo.
Aluminium-Calcium (AlCa) Cored Hlau:
Kev sib xyaw:Kev sib xyaw ntawm Aluminium (Al) thiab Calcium (Ca).
Mechanism:Aluminium yog ib qho muaj zog deoxidizer, ntau dua li silicon. Nws scavenges oxygen sai, tsim Al₂O₃. Qhov sib ntxiv ntawm calcium ces hloov cov txhuas oxides rau hauv spherical, tsis yog -deformable inclusions.
Cov txiaj ntsig tseem ceeb:Nws muaj lub zog deoxidation huab cua ua ke nrog kev tswj hwm zoo heev, tshwj xeeb tshaj yog siv tau zoo hauv cov hlau uas txhuas twb tau siv los ua thawj deoxidant.

2. Kev ua tau zoo ntawm Lub Tsev Muag Khoom: Ib Lub Taub Hau - mus rau - Lub taub hau sib piv

Yuav ua tau kim dua vim cov nqi raw khoom ntau dua (Al).

3. Daim Ntawv Thov Scenario: Qhov Chaw Txhua Lub Hlau Ci

Koj qhov kev xaiv yuav tsum tau hais los ntawm cov kev cai tshwj xeeb ntawm koj qib steel thiab txheej txheem.
Xaiv Silica-Calcium (SiCa) Thaum:
Koj xav tau kev desulfurization dav dav.​ Rau kev ua tau zoo - cov yeeb nkab zoo, lub siab lub nkoj steel, thiab lwm yam kev siv tseem ceeb uas yuav tsum tau muaj ultra- qib sulfur tsawg (<0.005%).
Koj tab tom tsim cov khoom nruab nrab- carbon thiab qis- alloy steels.Nws cov chemistry sib npaug ua rau nws zoo tagnrho rau cov qib no yam tsis muaj kev hloov pauv ntau dhau ntawm lawv qhov sib xyaw.
Koj xav txhim kho castability thiab txo cov nozzle clogging.Lub globular inclusions tsim los ntawm SiCa txhawb kom zoo dua ntws los ntawm tundish thiab submerged nkag nozzle (SEN).
Koj tau tsom mus rau tag nrho cov txheej txheem stability thiab tawm los.SiCa muab cov txiaj ntsig kwv yees thiab tau txais txiaj ntsig zoo ntawm kev nqis peev.
Xaiv Aluminium -Calcium (AlCa) Thaum:
Koj cov hlau yog "Al{0}}tua lawm."Yog tias txhuas tau ntxiv los ua tus thawj deoxidizer, AlCa yog tus khub zoo tshaj plaws los tswj cov txiaj ntsig alumina suav nrog.
Koj yuav tsum tau deoxidation siab tshaj plaws.Rau qee yam hluav taws xob steels lossis cov alloys tshwj xeeb uas cov pa oxygen seem yuav tsum raug txo kom tsawg rau xoom.
Koj tab tom cuam tshuam nrog cov teeb meem loj nozzle clogging los ntawm cov tawv alumina deposits.AlCa yog tshwj xeeb tshaj yog zoo ntawm spheroidizing cov tawv ncauj inclusions.

Xaus: Nws tsis yog hais txog qhov twg zoo dua, tab sis qhov zoo rau koj.
