Hauv kev tsim khoom ntawmqib siab - thiab cov hlau tshwj xeeb, zoo lihluav taws xob hlau (silicon steel), hlau huv rau kev siv tsheb, thiab qee yam stainless hlau, lub xub ntiag ntawm txhuas (Al) thiab titanium (Ti) hauv ferrosilicon yog suav tias yog qhov tsis zoo. Ntawm no yog yuav ua li cas covTsawg Al thiab Ti cov ntsiab lusnyob rau hauv hwm Lavxias teb sab ferrosilicon muab cov txiaj ntsig tseem ceeb:
1. Txhim kho steel huv huv thiab muaj tsawg dua
Kev puas tsuaj Oxide tsim:Txhuas thiab titanium yog cov deoxidizers muaj zog (txawm tias muaj zog dua silicon). Thaum qhia los ntawm ferrosilicon, lawv tuaj yeem tsim nyuaj, nyuajAlumina (Al₂O₃)thiabtitanium oxide / nitride (TiO₂, TiN)inclusions nyob rau hauv lub molten steel.
Teeb meem tshwm sim:Cov inclusions no yog abrasive, tuaj yeem txhaws submerged nkag nozzles hauv cov casters tas li, thiab, qhov tseem ceeb tshaj plaws, ua qhov tsis xws luag hauv cov khoom kawg. Lawv txo ductility, qaug zog, thiab nto zoo.
Cov txiaj ntsig ntawm Cov Ntsiab Lus Tsawg:Siv tsawg-aluminium ferrosilicon txo qhov tsim ntawm cov exogenous inclusions, ua rauhuv hlaunrog zoo internal kev ncaj ncees thiab nto tiav.
2. Txhim kho cov khoom sib nqus hauv hluav taws xob hlau
Nov yog daim ntawv thov tseem ceeb tshaj plaws thiab tshwj xeeb.
Hluav taws xob hlau(siv nyob rau hauv transformer cores thiab hluav taws xob motors) yuav tsum tau tsawg heevcore poobthiab siabSib nqus permeability. Txhua yam uas tsis yog- sib nqus los yog nyuaj, tshwj xeeb tshaj yogalumina, cuam tshuam loj heev ntawm cov qauv sib nqus, ua rau lub zog poob (hysteresis poob) raws li cov hlau nplaum sib hloov.
Cov txiaj ntsig ntawm Cov Ntsiab Lus Tsawg:Ferrosilicon nrog<0.01% Alfeem ntau teev rau daim ntawv thov no. Nws siv tiv thaiv cov khoom siv txhuas uas yuav rhuav tshem cov khoom sib nqus, tso cai rau cov hlau kom ua tiav nws cov qauv tsim. Russia tau keeb kwm yog tus xa khoom tseem ceeb rau lub niche no, siab - tus nqi lag luam.
3. Tswj Microalloying rau cov khoom tshwj xeeb
Hauv ntau cov hlau siab heev, titanium yog txhob txwm ntxiv rau qhov tseeb, feeb tus nqi (raws li cais microalloy) los ua TiN los yog TiC precipitates uas pin lis ciam teb thiab txhim kho lub zog.
Teeb meem nrog Uncontrolled Ti:Yog hais tias titanium nkag mus rau hauv lub yaj unpredictably ntawm ferrosilicon, nws disrupts no meej chemistry tswj. Nws tuaj yeem ua rau tsim cov ntxhib, tsis xav tau Ti- nplua nuj suav nrog lossis cuam tshuam rau cov txiaj ntsig ntawm lwm cov khoom siv microalloying xws li niobium (Nb).
Cov txiaj ntsig ntawm Cov Ntsiab Lus Tsawg:Tsawg-titanium ferrosilicon ua kom ntseeg tau tias tus tsim steel muajua tiav kev tswj hwm cov ntsiab lus Ti kawg, tso cai rau kev tsim metallurgical meej.
4. Castability zoo dua thiab txheej txheem ruaj khov
Alumina inclusions tuaj yeem tsim nyob rau hauv cov ntaub ntawv refractory thiab txhaws qhov nqaim nozzles ntawm lub tshuab nruam nruam, ua rau muaj kev cuam tshuam rau kev ua haujlwm, txo qhov nrawm nrawm, thiab tawm los poob.
Cov txiaj ntsig ntawm Cov Ntsiab Lus Tsawg:Los ntawm minimizing aluminium input, qhov kev pheej hmoo ntawmclogging (alumina buildup)raug txo kom tsawg. Qhov no ua kom cov txheej txheem ua kom zoo dua qub, ruaj khov dua nrog kev cuam tshuam tsawg dua, uas yog qhov tseem ceeb rau kev tsim khoom thiab zoo ib yam nyob rau hauv kev ua haujlwm ntev casting.
5. Predictable thiab ua tau zoo ib yam
High-purity, qis- impurity ferrosilicon ua raws li ib tugtxhim khu kev qha thiab kwv yees tus neeg sawv cev alloying. Lub steelmaker tuaj yeem xam qhov tseeb silicon ntxiv yam tsis muaj kev txhawj xeeb txog cov kev mob tshwm sim ntawm cov khoom tsis xav tau. Qhov kev sib xws no yog qhov tseem ceeb tshaj plaws rau kev tsim cov hlau kom nruj, thoob ntiaj teb kev lees paub tshwj xeeb (xws li ASTM, EN).
Summary for Commercial Pitch:
"Rau cov neeg tsim khoom ntawm cov khoom siv hluav taws xob, qib siab hauv tsheb, thiab lwm yam siab -kev ua tau zoo alloys, peb cov Lavxias teb sab ferrosilicon nrog lav tsis tshua muaj aluminium thiab titanium cov ntsiab lus tsis yog cov khoom siv raw xwb - nws yog cov cuab yeej muaj kev ruaj ntseg zoo. Nws ua kom cov hlau huv huv, tiv thaiv cov khoom sib nqus tseem ceeb, txhim kho castability, thiab xa cov khoom sib xws. yields, tsawg dua tsis xws luag, thiab superior kawg - khoom ua tau zoo rau koj cov neeg muas zaub."
Qhov kev coj dawb huv no yog qhov laj thawj tseem ceeb vim li cas qee cov qib Lavxias teb sab ferrosilicon hais kom tus nqi thiab tau nrhiav tom qab rau kev thov cov ntawv thov steel.
