High Carbon Ferrochrome Refine Method Kunyungudutsa Pakati-pasi Carbon Ferrochrome

Chrome ore inonatsa yakakwira kabhoni ferrochrome: kana uchinatsa yakakwira kabhoni ferrochrome ine chrome ore, yekunatsa slag ine hombe viscosity uye yakakwirira kunyungudika nzvimbo, uye tembiricha yekunyungudutsa inofanira kunge yakakwira. Naizvozvo, mashandisirwo emagetsi akakwira, hupenyu hwebindu rechoto hupfupi, uye kabhoni yemukati haisi nyore kudzika. Oxygen inovhuvhuta yakakwira kabhoni ferrochrome ine hukuru hukuru, senge kubereka kwakanyanya, mutengo wakaderera, mwero wekupora. Parizvino, iyo yechinyakare kugadzirwa nzira kana electro-silicon kupisa nzira. Electrosilicon kupisa nzira ndeyekugadzira alkaline slag muchoto chemagetsi pasi pemamiriro esilicon musilicon chromium alloy kuderedza chromium uye iron oxides, kuitira kuti ibudise yakaderera kabhoni ferrochrome.

Kufefetedza okisijeni kucheneswa kwe low carbon ferrochrome: Oxygen blowing nzira yekunatsa yakaderera kabhoni ferrochrome uchishandisa midziyo inoshandura, saka inodaidzwa kunzi converter method. Zvinoenderana nenzira dzakasiyana dzekupa mweya weokisijeni, kuvhuvhuta kweokisijeni kunogona kukamurwa kuita marudzi mana ekuvhuvhuta kudivi, kuvhuvhuta kumusoro, kuvhuvhuta kwepasi uye kumusoro nepasi kukapetwa kaviri. Nyika yedu inotora nzira yepamusoro yekuvhuvhuta inoshandura. Oxygen blowing nzira ndeyekufuridza okisijeni yakananga mumvura yakakwira-kabhoni ferrochrome kuti iite decarburised uye kugadzira yakaderera kabhoni ferrochrome. Zvinhu zvikuru muyakakwira kabhoni ferrochrome chromium, iron, silicon uye kabhoni, izvo zvese zvinogona kuve oxidised. Basa guru re oxidation inovhuvhuta yakakwira kabhoni ferrochrome ndeye decarbonise uye kuchengetedza chromium. Kana okisijeni ikafuridzirwa mumvura yakakwira-kabhoni ferrochrome, nekuti zvirimo muchromium nesimbi zvinodarika 90% yehuwandu hwealloy, saka yekutanga oxidation yechromium nesimbi, uyezve, maokisi aya anozobviswa. iyo silicon mune alloy. Nekuda kweiyo oxidation yechromium, iron uye silicon, tembiricha yedziva yakanyungudutswa inowedzera nekukurumidza, uye decarburisation reaction inokura nekukurumidza. Iyo yakakwira tembiricha, iyo inonyanya kufarirwa iyo decarburisation reaction, uye inogona kuvharidzira oxidation reaction yechromium, uye yakadzika kabhoni mualloy inogona kuderedzwa.
