I-VAD Furnace Refractory

I-VAD sisishunqulelo se-vacuum arc degassing, indlela ye-VAD iphuhliswe yinkampani ye-Finkl kunye nenkampani ye-Mohr, ngoko ikwabizwa ngokuba yi-Finkl-Mohr indlela okanye indlela ye-Finkl-VAD. Isithando somlilo se-VAD sisetyenziselwa ikakhulu ukucubungula i-carbon steel, insimbi yensimbi, intsimbi yokuthwala, insimbi ephezulu ye-ductility kunye nokunye.

Izixhobo zokucoca i-VAD ikakhulu zenziwe nge-ladle yensimbi, inkqubo yokufunxa, izixhobo zokufudumeza ze-arc zombane kunye nezixhobo zokongeza i-ferroalloy.

Iimpawu zendlela ye-VAD

1. Isiphumo esihle sokutshisa ngexesha lokufudumala, kuba ukufudumala kwe-arc yombane kwenziwa kwimeko ye-vacuum.
2. Iyakwazi ukulungelelanisa ngokuchanekileyo iqondo lobushushu lokuphosa ulwelo lwentsimbi, i-ladle yensimbi yangaphakathi inokuvuselela ngokwaneleyo ubushushu, ukuhla kobushushu kuzinzile ngexesha lokuphosa.
3. Ulwelo lwensimbi lunokushukunyiswa ngokupheleleyo ngexesha lokusulungekiswa, ukubunjwa kolwelo lwentsimbi kuzinzile.
4. Isixa esikhulu se-alloy sinokudibaniswa kulwelo lwentsimbi, uluhlu lweentlobo zokunyibilikisa lubanzi.
5. Ii-agent ze-slagging kunye nezinye izinto ze-slagging zingongezwa kwi-desulfurization, i-decarburization. Ukuba umpu weoksijini uxhotyiswe kwindawo yokuvala ivacuum, indlela yokufunxa ioksijini yokuphelisa i-carburization ingasetyenziselwa ukunyibilikisa intsimbi ye-ultra low carbon stainless.

Umsebenzi we-VAD furnace steel ladle ulingana ne-arc yombane yokunyibilikisa isithando somlilo. Isithando somlilo se-VAD sisebenza kwimeko yokucoca, i-ladle yensimbi esebenzayo itsala ulwelo lwentsimbi kunye ne-slag etyhidiweyo ukubola kweekhemikhali kunye nokuhlamba ngoomatshini, okwangoku, i-arc yombane ye-thermal radiation yomelele, ubushushu buphezulu, indawo eshushu iya kuba nomonakalo omkhulu. Ukongeza kwi-ejenti ye-slagging, i-slag corrosion inzima, ngakumbi indawo yomgca we-slag kunye nenxalenye ephezulu, isantya sokubola sikhawuleza ngakumbi.

Ukukhethwa kwezixhobo ze-VAD zokugqoka i-ladle ye-refractory kufuneka zamkele iintlobo ezahlukeneyo zezitena eziphikisayo ngokwemeko yobugcisa bokwenene, ngoko ke ubomi benkonzo bude kwaye ukusetyenziswa kwezinto eziphikisayo kuyancipha.

Izinto ezichasayo ezisetyenziswe kwindlela ye-VAD ikakhulu zibandakanya: izitena ze-magnesia chrome, izitena ze-carbon magnesia, izitena ze-dolomite kunye nokunye.

Umbane osebenzayo wamkela izitena ze-chrome ezidityanisiweyo ngokuthe ngqo, izitena ze-magnesite ze-chrome ezibotshiweyo kunye nezitena ze-chromite eziphindwe kabini, izitena zekhabhoni yemagneti, izitena ze-alumina ezitshisiweyo okanye ezingatshiswanga kunye nezitena ze-dolomite ezinobushushu obuphantsi, njl njl. izitena ze-fireclay kunye nezitena ezikhaphukhaphu eziphezulu ze-alumina.

Kwezinye iziko le-VAD, i-ladle ephantsi yokusebenza i-lining ihlala ithatha izitena ze-zircon kunye ne-zircon refractory ramming mixes. Ngezantsi inxalenye yomgca we-slag ifakwe ngezitena eziphezulu ze-alumina. Inxalenye yomgca we-slag yakhiwe ngezitena ezidibeneyo ze-chrome ze-magnesia. Ngaphezulu komgca we-slag kwindawo eshushu yakhiwe ngezitena zekhabhoni ze-magnesia ezidityaniswe ngokuthe ngqo, ngelixa inxalenye eseleyo isitena esisetyenzwe ngezitena zekhromite ezidityaniswe ngokuthe ngqo.

I-VAD ladles slag line part iphinda ithathe izitena ezidityanisiweyo ze-chrome ze-magnesia kunye nezitena ezidityanisiweyo ze-chrome. I-Ladle phantsi yokusebenza kwe-ladle ifakwe ngezitena ze-zircon. Iplagi enombhobho iphezulu i-alumina mullite esekwe, kwaye ezinye iindawo zonke zakhiwe ngezitena eziphezulu ze-alumina ezingatshiswanga.
