Kunyunguduka kweZhenAn's ferro vanadium

Ferrovanadium smelting method electrosilicothermal process, flake vanadium pentoxide ine 75% ferrosilicon uye shoma shoma yearuminiyamu sezvinoderedza, mualkaline arc furnace, kuburikidza nekuderedza nekunatsa matanho maviri kugadzira zvigadzirwa zvinokwanisa. Munguva yekuderedza nguva, iyo yose inoderedza mumiriri wevira uye flake vanadium pentoxide accounting ye60 ~ 70% yehuwandu hwese inotakurwa muchoto chemagetsi, uye kuderedzwa kwesilicon kupisa kunoitwa pasi pepamusoro calcium oxide slag. Kana iyo V2O5 mu slag isingasviki 0.35%, iyo slag (inonzi lean slag, inogona kuraswa kana kushandiswa sezvivakwa zvekuvaka) inoburitswa uye inotamirwa kunguva yekunatsa. Panguva ino, flake vanadium pentahydrate uye lime inowedzerwa kuti ibvise yakawandisa silicon nealuminium mumvura yealloy, uye iron alloy inogona kuburitswa kunze kana iyo alloy kuumbwa kunosangana nezvinodiwa. Iyo slag yakabudiswa munguva yekupedzisira yekunatswa inonzi hupfumi slag (ine 8 ~ 12% V2O5), iyo inodzoserwa kushandiswa apo choto chinotevera chinotanga kudya. Alloy liquid inowanzokandwa mucylindrical ingot, mushure mekutonhodza, kubvisa, kupwanya uye kuchenesa slag kwapera. Iyi nzira inowanzo shandiswa pakunyungudutsa iron vanadium ine 40 ~ 60% vanadium. Iyo yekudzoreredza mwero wevanadium inogona kusvika 98%. Simbi yekunyungudutsa vanadium inoshandisa 1600 kW • h yemagetsi patani.

Aluminium inoshandiswa seyekudzikisa mumiririri mune thermite process, iyo inonyungudutswa nenzira yepasi yekupisa muchoto chubhu yakamisikidzwa nealkaline choto. Kutanga chikamu chidiki chechaji yakasanganiswa mu reactor, ndiko kuti, mutsara wekudzima. Kusara kwemhosva kuchawedzerwa zvishoma nezvishoma mushure mokunge maitiro atanga. Inowanzoshandiswa pakunyungudutsa simbi yakakwirira (ine 60 ~ 80% vanadium), uye chiyero chekudzorera chinoderera zvishoma pane che electrosilicon thermal method, inenge 90 ~ 95%.
