Mai hana dumama wutar VAD

VAD shine taƙaitaccen bayani game da cire gas daga injin, kamfanin Finkl da kamfanin Mohr ne suka haɓaka hanyar VAD tare, don haka ana kiranta hanyar Finkl-Mohr ko hanyar Finkl-VAD. Ana amfani da tanda ta VAD galibi don sarrafa ƙarfe na carbon, ƙarfe na kayan aiki, ƙarfe mai ɗaukar kaya, ƙarfe mai ƙarfi da sauransu.

Kayan aikin tace VAD galibi sun ƙunshi ladle na ƙarfe, tsarin injin tsotsa, kayan dumama wutar lantarki da kayan ƙara ferroalloy.

Halayen hanyar VAD

1. Kyakkyawan tasirin cire gas yayin dumama, saboda dumamar baka ta lantarki ana yin ta ne a yanayin injin.
2. Za a iya daidaita zafin simintin ruwa na ƙarfe daidai, rufin ciki na ladle na ƙarfe zai iya sake farfaɗo da zafi yadda ya kamata, raguwar zafin jiki yana da ƙarfi yayin simintin.
3. Ana iya jujjuya ruwan ƙarfe gaba ɗaya yayin tacewa, abun da ke cikin ruwan ƙarfe yana da ƙarfi.
4. Ana iya ƙara yawan ƙarfe a cikin ruwa na ƙarfe, nau'in narkewar yana da faɗi.
5. Ana iya ƙara sinadaran rage ƙarfin iska da sauran kayan rage ƙarfin iska don rage ƙarfin iska da kuma rage ƙarfin iska. Idan an sanya bindigar iskar oxygen a murfin injin, ana iya amfani da hanyar rage ƙarfin iskar oxygen don rage ƙarfin iskar gas mai ƙarancin iskar gas.

Aikin ladle ɗin ƙarfe na tanda na VAD yayi daidai da tanderun ƙarfe na lantarki. Tanderun VAD yana aiki a yanayin injin, layin aiki na ladle na ƙarfe yana fama da ruwa na ƙarfe da narkakken slag na sinadarai da kuma wanke-wanke na inji, a halin yanzu, hasken wutar lantarki yana da ƙarfi, zafin jiki yana da yawa, yankin zafi zai yi mummunan lalacewa. Tare da ƙarin sinadarin slag, tsatsa ta slag tana da tsanani, musamman yankin layin slag da ɓangaren sama, saurin tsatsa ya fi sauri.

Zaɓar kayan da ke hana ruwa shiga layin VAD ya kamata su yi amfani da nau'ikan tubalan da ke hana ruwa shiga daban-daban bisa ga yanayin aikin, don haka tsawon lokacin sabis ɗin zai daɗe kuma yawan amfani da kayan da ke hana ruwa shiga zai ragu.

Kayayyakin da ke hana ruwa gudu da ake amfani da su a hanyar VAD sun haɗa da: tubalin magnesia chrome, tubalin carbon na magnesia, tubalin dolomite da sauransu.

Layin aiki galibi yana amfani da tubalin chrome na magnesia kai tsaye, tubalin chrome na magnesite da aka sake haɗawa da tubalin chromite na semi rebonded, tubalin carbon na magnesite, tubalin alumina mai ƙarfi ko mara wuta da tubalin dolomite mai ƙarancin zafin jiki, da sauransu. Layin dindindin galibi yana amfani da tubalin chrome na magnesia, tubalin fireclay da tubalin alumina mai sauƙi.

A wasu tanderun VAD, layin aiki na ƙasa na ladle yawanci yana amfani da tubalin zircon da gaurayen ramming na zircon. Sashen layin slag a ƙasan slag an yi shi da tubalin alumina mai tsayi. Sashen layin slag an gina shi ne ta hanyar tubalin magnesia chrome mai ɗaure kai tsaye. Ana gina wurin zafi na sama da tubalin carbon na magnesia mai ɗaure kai tsaye, yayin da sauran ɓangaren tubalin an yi shi ne ta hanyar tubalin magnesite chromite mai ɗaure kai tsaye.

Sashen layin ladles na VAD kuma yana amfani da tubalin magnesia chrome da aka haɗa kai tsaye da tubalin magnesia chrome da aka haɗa. An yi wa layin aiki na ƙasan ladle ɗin layi da tubalin zircon. Filogi mai ramuka yana da tushen alumina mullite mai yawa, sauran sassan kuma duk an gina su ne da tubalin alumina mai ƙarfi mara wuta.
