Kodi kugwiritsa ntchito chowonjezera cha carbon coke cha petroleum chopangidwa ndi graphitized chapamwamba kwambiri kungabweretse phindu lotani pazachuma kumakampani?

Kugwiritsa ntchito ma graphitized petroleum coke recarburizers apamwamba kwambiri kungabweretsere mabizinesi phindu lalikulu pazachuma m'mbali zosiyanasiyana, kuphatikizapo kuchepetsa ndalama zopangira, kukonza bwino zinthu, kukonza bwino ntchito yopanga, komanso kuwonjezera phindu loteteza chilengedwe. Kusanthula kwapadera kuli motere:

I. Kuchepetsa Ndalama Zopangira ndi Kukonza Kugwiritsa Ntchito Zinthu

Kuchepetsa Kugwiritsa Ntchito Chitsulo cha Nkhumba: Ma recarburizer a petroleum coke apamwamba kwambiri, omwe amadziwika ndi kuchuluka kwa kaboni kokhazikika (nthawi zambiri ≥98%) komanso kusakhala ndi zinyalala zochepa, amatha kusintha bwino gwero la kaboni mu chitsulo cha nkhumba. Malinga ndi deta yamakampani, kugwiritsa ntchito recarburizer iyi kungachepetse kugwiritsa ntchito chitsulo cha nkhumba ndi 20%-40%, ndikuchepetsa mtengo pa tani imodzi ya ma castings ndi pafupifupi 300-500 yuan. Mwachitsanzo, kampani yopanga zitsulo inapulumutsa ndalama zopitilira yuan miliyoni imodzi pachaka zogulira chitsulo cha nkhumba mwa kukonza chiŵerengero cha recarburizer.

Kukulitsa Chiŵerengero cha Kuyamwa: Chithandizo cha graphitization chimalola maatomu a kaboni kupanga kapangidwe kokonzedwa bwino, ndikuwonjezera kuchuluka kwa kuyamwa kuchokera pa 60% ya recarburizer wamba kufika pa 90%-95%. Izi zikutanthauza kuti recarburizer yochepa imafunika kuti tikwaniritse kuchuluka kwa kaboni komwe kukufunika, zomwe zimachepetsanso ndalama zomwe zimagwiritsidwa ntchito. Mwachitsanzo, popanga zitsulo za arc furnace, kuwonjezera 0.1%-0.3% ya recarburizer ya graphitized kungathe kusintha kuchuluka kwa kaboni mu chitsulo chosungunuka pomwe kumachepetsa nthawi yosungunulira ndi mphindi 15-20 ndikuchepetsa kugwiritsa ntchito mphamvu.

II. Kukweza Ubwino wa Zogulitsa ndi Kukweza Mpikisano wa Msika

Kupititsa patsogolo Kugwira Ntchito kwa Kuponya: Ma graphite microcrystals omwe ali mu graphitized petroleum coke recarburizers apamwamba kwambiri amatha kugwira ntchito ngati ma crystallization nuclei, zomwe zimapangitsa kukula kwa graphite flakes mu chitsulo choponyedwa. Mu chitsulo choponyedwa cha imvi, izi zitha kuwonjezera mphamvu yogwira ndi 15%-25%; mu ductile iron, zimatha kuwonjezera ma nodularity ndi 10%-20%. Mwachitsanzo, atasintha kugwiritsa ntchito recarburizer iyi, wopanga ma cylinder blocks a injini yamagalimoto adachepetsa kuchuluka kwa zolakwika zomwe zimaponyedwa kuchokera pa 15% mpaka 3%, zomwe zidapangitsa kuti phindu la zinthu liwonjezeke kwambiri.

Kukwaniritsa Zofunikira Zapamwamba: Makhalidwe a sulfure yotsika (≤0.05%) ndi nayitrogeni yotsika (≤400ppm) zimapangitsa kuti ma graphitized petroleum coke recarburizers akhale zida zofunika popanga ma castings apamwamba a magalimoto, zida zamagetsi zam'mphepo, ndi zinthu zina zofunika kwambiri. Kugwiritsa ntchito recarburizer iyi kungalepheretse zolakwika monga ming'alu ndi ma porosity omwe amayamba chifukwa cha sulfure ndi nayitrogeni, zomwe zimapangitsa kuti phindu la zinthu likhale lokwera.

III. Kukonza Bwino Ntchito Yopanga ndi Kuchepetsa Nthawi Yopanga

Kuwonjezeka kwa Liwiro la Kusungunula: Pakupanga zitsulo, ma graphitized petroleum coke recarburizers apamwamba amatha kusungunuka mwachangu ndikugawidwa mofanana, zomwe zimachepetsa nthawi yosungunula. Mwachitsanzo, mphero yachitsulo yafupikitsa kayendedwe kake ka kusungunula ng'anjo yamagetsi ndi 15%-20% mutagwiritsa ntchito recarburizer iyi, zomwe zawonjezera kutulutsa kwachitsulo pachaka ndi matani opitilira 10,000.

Kukhazikitsa Njira Zopangira: Kuyera kwambiri komanso kusakhala ndi zinyalala zambiri kwa recarburizer kumalepheretsa kusungunuka ndi kuwonongeka pa kutentha kwambiri, zomwe zimachepetsa kusinthasintha kwa kupanga. Mwachitsanzo, pakupangidwa kosalekeza, kugwiritsa ntchito recarburizer iyi kumatha kusunga mpweya wokhazikika mu chitsulo chosungunuka, kupewa mavuto a kupangidwa chifukwa cha kusinthasintha kwa mpweya.

IV. Kupititsa patsogolo Ubwino Woteteza Chilengedwe ndi Kukwaniritsa Zofunikira pa Chitukuko Chokhazikika

Kuchepetsa Utsi Woipa: Makhalidwe otsika a sulfure ndi nayitrogeni wa graphitized petroleum coke recarburizers amachepetsa kwambiri kutulutsa kwa sulfur dioxide ndi nitrogen oxides panthawi yoyaka. Mwachitsanzo, atagwiritsa ntchito recarburizer iyi, fakitale yopanga maziko inachepetsa ndalama zake zochotsera sulfure ndi 40% ndikuchepetsa kutulutsa kwa sulfur dioxide pachaka ndi matani ambiri.

Kulimbikitsa Kubwezeretsanso Zinthu: Pakupanga ma graphitized petroleum coke recarburizers, kutentha kwa zinyalala kumatha kubwezedwa kuti kupange magetsi, zomwe zimapulumutsa 300 kWh yamagetsi pa tani imodzi ya chinthu. Kuphatikiza apo, mpweya wammbuyo ukhoza kuperekedwa ku mafakitale ena (monga mafakitale a ceramic) ngati mafuta, zomwe zimapangitsa kuti zinthu zigwiritsidwe ntchito bwino. Mwachitsanzo, kudzera mu chitsanzo chozungulira cha zachuma, malo osungira zachilengedwe adachepetsa mpweya wa carbon ndi matani 1.2 pa tani imodzi ya recarburizer yopangidwa.
