3. Zinthu zakuthupi ndi zofunikira zaukadaulo pazofalitsa zapagulu ndi zothandizira

Kapangidwe ka silicon ya metallurgical makamaka amagwiritsa ntchito quartz monga chopangira chachikulu, chophatikizidwa ndi-malasha otsika, makala, kapena mafuta amoto polipiritsa mung'anjo, ndi matabwa omwe amagwiritsidwa ntchito ngati zida zothandizira. Kulipiritsa zinthu zoyengedwa bwino m'ng'anjo ndi njira yofunika kwambiri yowonetsetsa kuti ng'anjo ikugwira ntchito bwino, kuwongolera zinthu zabwino, komanso kuchepetsa ndalama zopangira. Mogwirizana ndi mfundo za kulipiritsa zinthu zoyengedwa, zofunikira zaukadaulo pazida zazikuluzikulu ndi izi:

3.1 Quartz

Zofunikira za kaphatikizidwe ka quartz zikuwonetsedwa mu Gulu 1.

Table 1-1 Chemical zikuchokeraquartz

SiO₂	Fe₂O₃	Al₂O₃	CaO	LOI (Loss on Ignition)	H₂O	UD
99.5%	0.04%	0.15%	0.05%	0.21	1%	0.05

Kukula kwa quartz ndi 20 ~ 120 mm.

Ngati mu quartz muli dothi musanayambe kugwedeza, iyenera kutsukidwa ndi madzi kuti nthaka ndi zomangira zina zisalowe mu ng'anjo ndikuipitsa mankhwala. Kuonjezera apo, katundu wa quartz ayenera kukhala ndi kukhazikika kwamphamvu kwa kutentha ndi chiwerengero cha antiknock ndi chachikulu kuposa 80%, kuonetsetsa kuti mphamvu yotentha itatha kudyetsedwa mu ng'anjo.

3.3 Electrode

Pantchitoyi, maelekitirodi a 33 MVA silicon metal electric arc ng'anjo amasankhidwa ngati ma elekitirodi a φ1272 mm, okhala ndi malire ovomerezeka a electrode m'mimba mwake a 1320 mm osungidwa. Zofunikira zaukadaulo zama electrode zikuwonetsedwa patebulo ili pansipa:

Kukaniza	Kulimba kwamakokedwe	Kuphulika mphamvu	Phulusa	Kuchuluka kwa voliyumu
＜25μΩ/m	＞2.5Mpa	＞5Mpa	＜1.5%	1.56-1.61g/cm3

3.4 Oxygen ndi mpweya woponderezedwa

Oxygen imagwiritsidwa ntchito makamaka pakuyenga zitsulo zamadzimadzi. Chiyero ndi choposa 92% ndipo kupanikizika ndi 0.6Mpa.

Mpweya woponderezedwa umagwiritsidwa ntchito poyeretsa osonkhanitsa fumbi, kuyeretsa malo opangira ng'anjo, kuyeretsa ladle ya silicon, kuwongolera pneumatic, etc., pamphamvu ya 0,6 MPa.

3.5 Magwero a magetsi

Magetsi osungunulira magetsi a ng'anjo yomira pansi pamadzi: 30/35/66/110 kV

Mphamvu yamagetsi: 11/10kV
pafupipafupi: 50Hz
Magetsi otsika AC400/230V

Zida zosungunulira

Chiyambi cha ndondomeko yotuluka

Kukonzekera Zopangira Zopangira

Msonkhanowu uli ndi dongosolo lathunthu lolipiritsa ndi kugawa zinthu. Kuwunika, kuphwanya, kuchapa, ndi zida zina zopangira zida zimakonzedwa molingana ndi momwe zida zikubwera.

Zopangira zonse zoyenerera zimanyamulidwa ndi galimoto kapena sitima kupita kumalo osungirako zinthu. Akamaliza kukonza, amatumizidwa kumalo opangira ma batching ndi makina onyamula, zotengera malamba, kapena zonyamula katundu. Pa batching station, zopangira zoyenerera zimayesedwa ndikusakanikirana molingana ndi magawo omwe atchulidwa pogwiritsa ntchito makina owerengera. Zosakanizazo zimaperekedwa ku ng'anjo yamagetsi kuti zisungunuke.

Zida zophatikizika zimadutsa mu bin, ng'anjo-chotengera chapamwamba lamba, galimoto yogawa mozungulira, ndi nkhokwe yosungira, ndiyeno zimalowetsedwa mung'anjo yamagetsi kudzera pa mapaipi ochazira kuti asungunuke ndi kuchepetsa. Chitoliro chothandizira chowonjezera kunja kwa ng'anjocho chimaperekedwa kuti chisamalidwe cholemetsa chamanja pansi pazikhalidwe zapadera zogwirira ntchito.

The osakaniza mlandu amakumana mosalekeza electrothermal kuchepetsa mkati ng'anjo. Silicon yosungunuka imapangidwa mosalekeza ndikuunjikana pansi pa ng'anjo. Ntchito zopopera silicon zimachitika pafupipafupi. Pogogoda, bowo la mpopi limatsegulidwa pogwiritsa ntchito kuwotcha-kupyolera mu makina, kulola silicon yosungunuka kulowa mu ladle ya silicon yoyikidwa pa galimoto ya ladle. Silicon wosungunuka mu ladle akafika pamlingo wina, amabayidwa mpweya kuti ayese silicon.

Kuyenga kumachitika pouzira mpweya-wowonjezera mpweya mu ladle kuti muchepetse aluminium ndi calcium. Pambuyo poyenga, silicon yosungunuka imatengedwera kumalo oponyera, kumene imatsanuliridwa mu nkhungu za ingot ndi crane yapamwamba kapena makina opendekera. Ma silicon metal ingot molds amayikidwa pa ngolo zosunthika, zomwe zimathandiza-kuponyera ma point osasunthika.

Pambuyo poziziritsa ndi kugwetsa, silizoni ya mafakitale imasamutsidwa kupita ku-zomaliza zopangira zinthu kuti ziphwanye, kulongedza, kuyesa, ndi kusanthula labotale. Miyendo ya silicon yomwe imagwiritsidwa ntchito poponya imatsukidwa, kukonzedwa, ndikuwotcha pambuyo pothira, kuwakonzekeretsa kuti agwire ntchito yotsatira.

Ng'anjo yozimitsidwa-gasi imayeretsedwa ndi dry baghouse dedusting system. Fumbi losonkhanitsidwa limachulukitsidwa, limapakidwa, ndikusungidwa, ndipo litha kugulitsidwa kwa opanga ngati zida zopangira zomangira, zida zomangira, zoumba, ndi mafakitale ena.

06/

Kuchuluka kwa fumbi mu gasi woyeretsedwa ndi wocheperapo kapena wofanana ndi 10 mg/Nm³, pokwaniritsa malamulo amderali komanso miyezo yotulutsa mpweya woipa wa mumlengalenga.
