Raws li lub tshuab nqus tsev refining khoom siv dav siv hauv high-end steel manufacturing, nws muaj qhov zoo heev degassing thiab deoxidizing teebmeem. Nws ua tiav kev tshem tawm cov hydrogen thiab nitrogen los ntawm cov hlau los ntawm kev tsim kom muaj qhov chaw nqus tsev, uas txo cov roj teeb meem hauv cov hlau tiav, uas yog qhov tseem ceeb rau kev txhim kho lub toughness thiab ductility ntawm cov hlau. Cov txheej txheem no tsis tsuas yog txhim kho qhov zoo ntawm cov hlau, tab sis kuj tseem txuas ntxiv nws lub neej kev pab cuam, uas yog qhov tseem ceeb tshwj xeeb hauv kev tsim cov khoom tshwj xeeb steel uas xav tau huab purity thiab kev ua haujlwm siab.

VD rauv ua tau zoo txo ​​cov hydrogen thiab nitrogen cov ntsiab lus ntawm cov hlau, tshem tawm cov pa oxygen ntawm cov hlau los ntawm cov pa roj carbon thiab oxygen, thiab desulfurizes cov hlau los ntawm tag nrho cov tshuaj tiv thaiv ntawm alkaline sab saum toj slag nrog cov hlau molten, ntxiv rau homogenizing muaj pes tsawg leeg thiab kub. Nrog nws cov kev ua tau zoo heev hauv degassing, deoxygenation, desulfurization, muaj pes tsawg leeg thiab kub homogenization, VD rauv tau dhau los ua cov cuab yeej siv thev naus laus zis tseem ceeb hauv kev lag luam steel niaj hnub los txhim kho cov khoom zoo, txhim kho cov txheej txheem ntau lawm, thiab ua tau raws li qhov xav tau ntawm high-end. khoom lag luam.
