Ndi chiyaniferrochrome?
Ferrochrome (FeCr) ndi aloyi wa chromium ndi chitsulo chokhala ndi chromium pakati pa 50% ndi 70%.Pa 80% ya ferrochrome yapadziko lonse lapansi imagwiritsidwa ntchito popanga chitsulo chosapanga dzimbiri.Malinga ndi zomwe zili ndi kaboni, zitha kugawidwa kukhala: Hndi carbon ferrochrome/HCFeCr(C:4% -8%),Mpweya wa carbon ferro chrome/MCFeCr(C:1% -4%),
Low carbon ferrochrome/LCFeCr(C:0.25% -0.5%),Micro carbon ferrochrome/MCFeCr:(C:0.03-0.15%).
Kodi ubwino wa ferrochrome ndi chiyani?
1. Chomera cha chromeali ndi mwayi wowonjezera kukana kwachitsulo kwa okosijeni popanga zitsulo.
Mu ndondomeko steelmaking mu ferrochrome akhoza mogwira kuonjezera makutidwe ndi okosijeni kukana zitsulo, ndi chromium chinthu mu ferrochrome angathe kuteteza chitsulo, kuti makutidwe ndi okosijeni mlingo wake m'mbuyo kuonjezera kukana makutidwe ndi okosijeni wa zitsulo, ali ndi mwayi kuwongolera utumiki. moyo wachitsulo;
2,Kuwonjezera gawo la ferrochrome muchitsulo chosungunuka kuli ndi mwayi wowongolera bwino kukana kwa dzimbiri kwachitsulo.
Popanga zitsulo, kuwonjezera kuchuluka kwa ferrochrome molingana ndi zomwe zili muzitsulo zosungunula zimatha kusintha kukana kwa dzimbiri.Chromium element mu ferrochrome imatha kumangirizidwa bwino pamwamba pazitsulo kuti ikhale yosanjikiza, motero kukhala ndi mwayi wokana dzimbiri.
3. Ferrochrome ili ndi ubwino wowongolera bwino kuuma ndi kuvala kukana kwachitsulo
Tsopano ndondomeko kupanga steelmaking ambiri anaika ferrochrome, chifukwa chachikulu ndi chifukwa ferrochrome akhoza bwino kusintha kuuma ndi kuvala kukana zitsulo, chromium chinthu mu ferrochrome n'zosavuta kuphatikiza ndi mpweya, kotero izo mogwira patsogolo luso la okosijeni zitsulo. kukana, kuwonjezera, ferrochrome akhoza kuyeretsa zitsulo zosafunika kusintha kuuma kwa chitsulo.
Kugwiritsa ntchito ferrochrome
① Chimagwiritsidwa ntchito popanga chitsulo chosapanga dzimbiri, Chitsulo chosapanga dzimbiri chimadalira chromium pamawonekedwe ake komanso kukana dzimbiri.
②Monga chowonjezera chachikulu cha aloyi pakupanga zitsulo
③Monga chowonjezera chofunikira pakusungunuka kwachitsulo chochepa cha carbon
