Kodi ntchito ya petroleum coke yokhala ndi graphitized ndi yotani m'mafakitale osungunula monga silicon ndi silicon carbide?

Udindo wa Graphitized Petroleum Coke mu Mafakitale Osungunula a Industrial Silicon ndi Silicon Carbide

I. Udindo mu Industrial Silicon Smelting

1. Ntchito Yothandizira Kuchepetsa Pakati
Coke ya petroleum yokhala ndi grafiti ndi imodzi mwa zinthu zazikulu zochepetsera mpweya m'mafakitale opanga silikoni. Kuchuluka kwa mpweya m'mafakitale (90%-97%) komanso phulusa lochepa zimapangitsa kuti ikhale chinthu chofunikira kwambiri popanga mpweya wofunikira pakuchitapo kanthu. Pakusungunula ng'anjo yamagetsi, coke ya petroleum imathandiza kusintha silica (SiO₂) kukhala silikoni yamakampani kudzera mukuchitapo kanthu kochepetsa kutentha kwa thupi. Kuphatikiza apo, kuyendetsa kwake kwamagetsi kumathandiza kuwongolera kukana kwa mphamvu ya ng'anjo, kuwongolera kuya kwa kuyika kwa ma electrode ndikukonza bwino ntchito ya ng'anjo yamagetsi.

2. Kukonza Bwino Ntchito Yogulira Ng'anjo

• Kusintha kwa Kukana: Kuyenda kwa magetsi kwa petroleum coke kumakhudza kukana kwa mphamvu ya ng'anjo. Mwa kusintha mlingo wake ndi kukula kwa tinthu, mphamvu ya kutentha ya ng'anjo yamagetsi imatha kukonzedwa bwino, zomwe zimachepetsa kugwiritsa ntchito mphamvu.
• Kukonza Kuthira Madzi: Coke ya petroleum yoyera imakonda kupangika pa kutentha kwambiri, zomwe zimapangitsa kuti thunthu lipangike pamwamba pa ng'anjo. Pofuna kuchepetsa izi, matabwa kapena utuchi zimasakanizidwa kuti ziwonjezere kukana kwapadera, kupititsa patsogolo kulowetsedwa kwa madzi mu ng'anjo, komanso kukhazikika kwa magwiridwe antchito.
• Kuonjezera Ntchito Zamankhwala: Petroleum coke ili ndi mphamvu zochepetsera thupi zochepa ndipo nthawi zambiri imagwiritsidwa ntchito limodzi ndi makala a silicon otsika phulusa kapena makala kuti zitsimikizire kuti zinthu zikuyenda bwino.

3. Kulinganiza Pakati pa Ubwino ndi Mtengo

• Kupanga Silikoni Yapamwamba: Kuchuluka kochepa kwa phulusa mu petroleum coke kumapangitsa kuti ikhale yoyenera kupanga silikoni yamafakitale yoyera kwambiri. Komabe, sulfure, vanadium, nickel, ndi zonyansa zina ziyenera kulamulidwa, makamaka popanga organosilicon, komwe kuchuluka kwa petroleum coke kumakhala kochepa kuti tipewe poizoni wa catalyst.
• Ubwino Wachuma: Poyerekeza ndi makala, petroleum coke imapezeka kwambiri, mtengo wake ndi wokhazikika, ndipo sichikhudzidwa kwambiri ndi mfundo zachilengedwe, zomwe zimapangitsa kuti ikhale chinthu chochepetsera kwambiri popanga zinthu zambiri.

II. Udindo mu Silicon Carbide Smelting

1. Kupereka Magwero a Kaboni
Kupanga kwa silicon carbide (SiC) kumafuna gwero la kaboni loyera kwambiri. Pambuyo pa calcination, graphitized petroleum coke imawonetsa kuchepa kwa volatility ndi graphitization yowonjezera, zomwe zimapangitsa kuti carbon source ikhale yokhazikika yomwe imalimbikitsa solid-phase reaction pakati pa silicon ndi kaboni kuti ipange silicon carbide yoyera kwambiri.

2. Kugwiritsa Ntchito Zinthu Zosakhazikika
Coke ya petroleum ingagwiritsidwe ntchito mwachindunji popanga zinthu zopopera za silicon carbide (monga mawilo opukutira, sandpaper). Kuuma kwake kwakukulu komanso kukana kukalamba kumapangitsa kuti ikhale chinthu chofunikira kwambiri popanga zitsulo, kupukuta ceramic, ndi zina.

3. Kukonza Njira

• Chithandizo cha Calcination: Kuchepetsa mafuta osaphika a coke pa 1300°C kumachepetsa kuchuluka kwa haidrojeni ndikuwonjezera graphitization, kukonza mphamvu zamagetsi ndi kukana kutentha kwa zinthu za silicon carbide.
• Kuwongolera Kukula kwa Tinthu: Kusintha kukula kwa tinthu ta petroleum coke kumathandizira kuti njira yopangira silicon carbide ikhale yolimba, zomwe zimapangitsa kuti zinthu zikhale zofanana.

III. Udindo Wonse ndi Kufunika kwa Makampani

1. Kugwira Ntchito Mwanzeru Posungunula
Kukhazikika kwa magetsi ndi kukhazikika kwa mankhwala a petroleum coke yojambulidwa kumachepetsa kugwiritsa ntchito mphamvu mu uvuni zamagetsi, kufupikitsa kayendedwe ka kusungunula, ndikuwonjezera magwiridwe antchito. Mwachitsanzo, popanga silicon yamafakitale, kusakaniza bwino kwa petroleum coke kumatha kuchepetsa kugwiritsa ntchito mphamvu ndi 5%-10%.

2. Chitsimikizo cha Ubwino
Kulamulira kuchuluka kwa sulfure, phulusa, ndi kuipitsidwa mu petroleum coke kumachepetsa zinthu zomwe sizili zachitsulo zomwe zimapezeka mu silicon yamafakitale ndipo kumawonjezera kuyera kwa silicon carbide, zomwe zimakwaniritsa zofunikira za opanga apamwamba (monga semiconductor-grade silicon carbide).

3. Kupititsa patsogolo Kukweza Mafakitale
Pamene makampani opanga zitsulo akupita patsogolo kupita ku ntchito zazikulu komanso zanzeru, kuyera kwakukulu kwa petroleum coke yokhala ndi graphitized komanso crystallinity kumathandizira kupanga ma electrode pastes apamwamba komanso ma carbon electrodes akuluakulu, zomwe zimapangitsa kuti ukadaulo ukhale wokwera kwambiri m'gawo lonselo.
