Lub hauv paus rau phau ntawv
Hauv kev tsim tawm steel, tswj kev impurities thiab txhim kho tag nrho cov khoom zoo ntawm cov hlau yog qhov tseem ceeb rau kev ua tiav siab- Cov ntaub ntawv ua tau zoo. Ib alloy uas ua si lub luag haujlwm tseem ceeb hauv cov txheej txheem noFerro Silicon Barium (Fesiba)Cov. Raws li lub zog muaj zog thiab inoculant, fesiba pab Refine Stainless Micrustrusions, txo cov kev suav, thiab txhim kho cov khoom ntiag tug. Cov lus qhia no piav qhia txog kev siv FESIBA txhawm rau txhim kho cov hlau zoo thiab huv.

1. Nkag siab lub luag haujlwm ntawm Fesiba hauv Steelmaking
Fesiba yog feem ntau tsim ntawm:
Silicon (si): Tubtxib Tes Haujlwm ua tus deoxidizer.
Barium (ba): Txawj ua cov deoxidation thiab hloov kho cov duab uas suav nrog.
Cov hauj lwm tseem ceeb:
Tshem tawm cov pa los ntawm kev tsim cov khoom siv oxides ruaj khov
Hloov pauv tsis - nws yog xim hlau suav, ua rau lawv tsis muaj kev phom sij
Tiv thaiv reoxidation ntawm molten hlau
Txhim Kho Cov Hlau Huv Huv thiab De Tiav
2. Xaiv cov qib ntawm Fesiba
Fesiba alloys tuaj nyob rau hauv ntau yam muaj pes tsawg xyoo. Cov kev qhia tshwj xeeb muaj xws li:
Cov ntsiab lus ntawm SII: 60–75%
Ba Cov Ntsiab Lus: 10–25%
Cov ntsiab lus: Tsawg dua los yog sib npaug rau 2%
C, P, S: Tswj hwm ntawm theem qis
Tus ntsis: Rau siab - Cov ntsiab lus tsis huv,}}}}}}} aluminium cov ntsiab lus kom ua tiav cov txiaj ntsig deoxidation thiab suav nrog kev hloov dua tshiab.
3. Ntxiv fesiba ntawm lub sijhawm yog nyob rau hauv tus txheej txheem
Kom ua hauj lwm zoo tshaj plaws:
Ntxiv Fesiba thaum lub sijhawm pw ua haujlwm theem, tom qab thawj deoxidizers zoo li txhuas lossis silicon manganese
Ua kom tau tiag tiagKev sib xyaw sib xyawHauv Molten Steel
Tswj xyuas kom zooQhov kub thiab qhov kub thiab tswjTxhawm rau tso cai rau tag nrho cov tshuaj tiv thaiv
4. Txiav txim siab qhov kev pom zoo ntxiv
Cov neeg raug ntxiv:
0.2% rau 0.5%los ntawm qhov hnyav ntawm molten hlau, nyob ntawm qib hlau thiab xav tau huv huv
Dhau kev ceeb toom: Kev ntxiv ntau dhau yuav ua rau kev ua txhaum cai lossis ua npuas ncauj tsis zoo; Nco ntsoov ua raws cov lus pom zoo metallgical lossis sab laj nrog koj cov khoom xa khoom.
5. Saib xyuas cov teebmeem ntawm cov tawv hlau
Siv FESIBA raug rau:
Qis dua tag nrho cov pa oxygen
Tsev ntxhua khaub ncaws steel thaj chaw
Tsawg dua thiab rounder inclusions, txhim kho ductility thiab tawv nruj
Zoo dua Weldability thiab Formability
Nce cov txiaj ntsig thiab txo qhov tsis xws luag
6. Saib xyuas thiab kho raws li cov txiaj ntsig
Tsis tu ncua kuaj hlauXam cov ntsiab lus, Cov Khoom Siv Neeg Kho Tshuab, thiabNto Zoo
Kho Fesibamuaj pes tsawglossisntxiv rau taw tesRaws li cov lus taw qhia los ntawm lab thiab cov ntaub ntawv ntau lawm
Tag
Fesiba yog cov tswv yim zoo li ntawd, thaum siv tau zoo, ua rau muaj kev txhim kho kom zoopurity, kev nyiam huv, thiab cov khoom siv mechaniesntawm hlau. Los xaiv cov qib zoo, ua kom tau cov txiaj ntsig ntxiv, thiab cov txiaj ntsig kev ua tau zoo, Steelmakers tuaj yeem ua tiav cov khoom lag luam ntau dua thiab cov hlau zoo dua.
