VAD Furnace Refractory

VAD ndiyo chidimbu chevacuum arc degassing, nzira yeVAD inogadziriswa nekambani yeFinkl nekambani yeMohr, saka inonziwo nzira yeFinkl-Mohr kana nzira yeFinkl-VAD. VAD choto chinonyanya kushandiswa kugadzira kabhoni simbi, chishandiso simbi, inotakura simbi, yakakwirira ductility simbi uye zvichingodaro.

VAD yekunatsa michina inonyanya kuumbwa nesimbi ladle, vacuum system, yemagetsi arc yekudziya michina uye ferroalloy inowedzera michina.

VAD nzira maitiro

1. Yakanaka degassing maitiro panguva yekudziya, nekuti magetsi arc kupisa anoitwa pavacuum mamiriro.
2. Inogona kunyatso gadzirisa simbi yekukanda tembiricha, simbi ladle yemukati lining inogona zvakakwana kudzoreredza kupisa, kudonha kwetembiricha kwakagadzikana panguva yekukanda.
3. Simbi yemvura inogona kuzungunuswa zvizere panguva yekunatswa, simbi yemvura yakagadzirwa yakagadzikana.
4. Huru huwandu hwealloy hunogona kuwedzerwa mumvura yesimbi, kunyungudutsa marudzi akasiyana akafara.
5. Slagging agents uye zvimwe slagging zvinhu zvinogona kuwedzerwa kuti desulfurization, decarburization. Kana pfuti yeokisijeni yakashongedzerwa pachivharo chevacuum, vacuum oxygen decarburization nzira inogona kushandiswa kunyungudutsa yakaderera kabhoni simbi isina tsvina.

Basa reVAD furnace steel ladle rakaenzana nemagetsi arc smelting furnace. VAD choto chinoshanda pavacuum mamiriro, simbi ladle inoshanda lining inotambura nesimbi yemvura uye yakanyungudutswa slag kemikari corrosion uye mechanic washing, ukuwo, magetsi arc thermal radiation yakasimba, tembiricha yakakwira, nzvimbo inopisa ichave nekukuvara kwakanyanya. Nekuwedzera kweiyo slagging agent, slag corrosion yakanyanya, kunyanya slag line zone uye chikamu chepamusoro, corrosion rate inotokurumidza.

Kusarudzwa kweVAD ladle lining refractory zvinhu zvinofanirwa kutora akasiyana marudzi ezvidhinha zvekuramba zvinoenderana nemamiriro chaiwo ehunyanzvi, saka hupenyu hwesevhisi hunorebesa uye kushandiswa kwezvinhu zvinoramba kuderedzwa.

Refractory zvinhu zvinoshandiswa muVAD nzira inonyanya kusanganisira: magnesia chrome zvidhinha, magnesia carbon zvidhinha, dolomite zvidhinha uye zvichingodaro.

Kushanda lining kunonyanya kutora yakananga bonded magnesia chrome zvidhinha, rebonded magnesite chrome zvidhinha uye semi rebonded magnesia chromite zvidhinha, magnesite kabhoni zvidhinha, akapiswa kana asina kupiswa arumina zvidhinha uye tembiricha yakagadziriswa zvidhinha zve dolomite, nezvimwewo. fireclay zvidhinha uye lightweight high alumina zvidhinha.

Mune mamwe mavira eVAD, ladle pasi inoshanda lining inowanzo tora zircon zvidhinha uye zircon refractory ramming musanganiswa. Pazasi slag mutsara chikamu chakamisikidzwa nepamusoro alumina zvidhinha. Slag line chikamu chinogadzirwa nechakananga bonded magnesia chrome zvidhinha. Pamusoro peslag line inopisa nzvimbo inovakwa neyakasungwa yakananga magnesia kabhoni zvidhinha, nepo chikamu chese chiri chidhinha chinoshandwa neyakasungwa yakananga magnesite chromite zvidhinha.

VAD ladles slag line chikamu zvakare inotora yakananga bonded magnesia chrome zvidhinha uye yakasanganiswa magnesia chrome zvidhinha. Ladle yepasi inoshanda lining yakashongedzwa ne zircon zvidhinha. Porous plug yakakwira alumina mullite yakavakirwa, uye zvimwe zvikamu zvese zvakavakwa neasina kupiswa yakakwira alumina zvidhinha.
