Ikhabhoni eFixed ePhezulu kunye noBumdaka obuphantsi obunobungozi
Isiqulatho sekhabhoni esisigxina Inkulu okanye ilingana nama-98.5% (ukuya kuthi ga kwi-99.5% kumabanga eprimiyamu); umxholo opheleleyo wokungcola okuyingozi (S Ngaphantsi okanye ilingana ne-0.15%, i-Fe₂O₃ Ngaphantsi okanye ilingana ne-0.8%, i-SiO₂ Ngaphantsi okanye ilingana ne-1.0%) ilawulwa ngokungqongqo, igwema imiphumo emibi kwintsebenzo ephezulu{5}}yobushushu obuphezulu bezitena zekhabhoni (umzekelo, i-spalling point okanye i-spalling point).
UHlelo lweSize seNqanaba eLunyusiweyo
Ubungakanani bemilinganiselo yamasuntswana enokwenziwa ngokwezifiso (umzekelo, 0-1mm, 1-3mm, 3-5mm) ukutshatisa izitena ezahlukeneyo ze-magnesium carbon; Ukusabalalisa ubungakanani besuntswana elimxinwa liqinisekisa ukuxubana okufanayo kunye nomgubo we-magnesia, ukuphucula ukuhambelana komzimba wezitena.
Okugqwesileyo okuPhezulu- kozinzo lobushushu
Ugcina ingqibelelo yesakhiwo kwi-1600-1800℃(ubushushu obuqhelekileyo bokusebenza kwezitena zekhabhoni ye-magnesium); i-coefficient yokwandisa i-thermal ephantsi (Ngaphantsi okanye ilingana ne-5.0 × 10⁻⁶/ degree) inciphisa umonakalo woxinzelelo lwe-thermal ngexesha lokufudumeza ngokukhawuleza / ukupholisa imijikelezo.
Ukumanzisa okuhle kunye nezibophelelo
Unyango lomphezulu (ukhetho) luphucula ukuhambelana ne-phenolic resin okanye i-pitch binders, ukukhuthaza ukudibanisa kwe-interfacial phakathi kwegraphite kunye ne-magnesia, kunye nokuphucula amandla omatshini onke wezitena (amandla e-flexural Omkhulu okanye alingana ne-15MPa emva kokudubula).
4. Iimeko zeSicelo eziPhambili
Steelmaking Converter Linings
Isetyenziswe ekuveliseni izitena zekhabhoni ye-magnesium kwi-converter linings (ingakumbi iindawo zomgca we-slag), isebenzise ukuxhathisa kwayo okuphezulu kwe-corrosion ukumelana nokukhukuliseka kwintsimbi etyhidiweyo kunye ne-slag.
ILadle kunye neTundish Linings
Ifakwe kwizitena zekhabhoni ye-magnesium kwi-ladle sidewalls, i-bottom, kunye ne-tundish linings ephezulu, ephucula ukuxhathisa ukothuka kwe-thermal kunye nentsimbi etyhidiweyo.
Izixhobo zoMbane zeArc (EAF).
Isebenza njengemathiriyeli ekrwada yezitena zekhabhoni yemagnesium kuphahla lwe-EAF nakwiindonga ezisecaleni, ukuziqhelanisa - nokusingqongileyo kobushushu (1600-1750 degree) kunye nokunciphisa ukugcinwa rhoqo.
{0}IziXhobo zeMetallurgy ezingezizo
Isetyenziswa kwizitena zekhabhoni yemagnesium kwizitena zokunyibilikisa (umzekelo, ikopolo, ukunyibilika kwenikeli), ukuxhathisa ukubola{2}}kubushushu obuphezulu betyuwa ezinyibilikisiweyo kunye neeoksidi zesinyithi.
