Graphite rotor kwa kuponyera aluminium

Chiyambi cha Zamalonda:

Mfundo yogwira ntchito ya agraphite rotorndi kuti rotor yozungulira imaswa nayitrogeni (kapena argon) yomwe imawomberedwa mu aluminiyamu kusungunula mumbiri yambiri yomwazika thovu ndikuwabalalitsa muzitsulo zosungunuka. Mivuvu yomwe imasungunuka imatenga haidrojeni kuchokera kusungunuka kutengera mfundo ya kusiyana kwapakati pagasi ndi kutsekemera kwapamtunda, adsorb oxidation slag, ndipo amatuluka pamwamba pomwe ming'oma ikukwera, zomwe zimapangitsa kuti kusungunuka kuyeretsedwe. Chifukwa cha kubalalitsidwa kwabwino kwa thovu, amasakanikirana ndi kusungunuka kozungulira ndikuyandama pang'onopang'ono mu mawonekedwe ozungulira. Amakhala ndi nthawi yayitali yolumikizana ndi kusungunula ndipo sapanga mpweya wowongoka mosalekeza, potero amachotsa haidrojeni yoyipa kuchokera ku aluminiyamu kusungunuka ndikuwongolera kwambiri kuyeretsa.

Makhalidwe a zinthu za graphite rotor:

1. Mphuno yozungulira ya graphite rotor imapangidwa ndi graphite yoyera kwambiri. 2. Pambuyo pa chithandizo chapamwamba, moyo wautumiki umakhala pafupifupi katatu kuposa zinthu wamba, ndipo umagwiritsidwa ntchito kwambiri pamakampani opanga aluminiyamu.

Pankhani ya chuma cha graphite rotor:

Pazinthu zopangira ma aluminiyamu aloyi ndi mafakitale a aluminiyamu, ndikofunikira kuchepetsa mtengo wokonza. Pachifukwa ichi, ma graphite rotor opangidwa ndi kampani yathu amatha kubweretsa zotsatirazi:

1. Chepetsani ndalama zolipirira

2. Chepetsani kugwiritsa ntchito mpweya wa inert

3. Chepetsani zinthu za aluminiyamu mu slag

4. Kuchepetsa ndalama zogwirira ntchito

5. Magwiridwe, nthawi yayitali yosinthira

6. Kupititsa patsogolo kudalirika ndi kuchepetsa ndalama zothandizira.

Kupanga ndi kuyitanitsa ma graphite rotor:

Chifukwa cha kusiyanasiyana kwa ma graphite rotor omwe amagwiritsidwa ntchito pamzere uliwonse wopanga kapena kugubuduza. Choyamba, kasitomala adzapereka zojambula zoyambirira ndi mawonekedwe athunthu ogwiritsira ntchito malo ogwiritsira ntchito malo a graphite rotor. Kenako, kutengera zojambulazo, kuwunika kwaukadaulo kudzachitika kuphatikiza liwiro, momwe kazungulira, ndi malo achibale ndi mulingo wamadzimadzi a aluminiyamu wa graphite rotor, ndipo ndondomeko yoyenera yothana ndi kukokoloka idzaperekedwa.

Mphuno yozungulira ya graphite rotor imapangidwa ndi graphite yoyera kwambiri. Kuphatikiza pa kufunikira komwaza thovu, kapangidwe ka nozzle kamagwiritsanso ntchito mphamvu ya centrifugal yomwe imapangidwa poyambitsa aluminium alloy kusungunula kuti isungunuke mumphuno ndi mpweya wopopera mopingasa, kupanga mpweya / madzi otuluka kuti upopera. , kuonjezera malo okhudzana ndi nthawi yolumikizana pakati pa thovu ndi aluminiyamu alloy madzi, ndikuwongolera kutulutsa mpweya ndi kuyeretsa. Kuthamanga kwa graphite rotor kungasinthidwe mosadukiza kudzera pa liwiro lotembenuza pafupipafupi, mpaka 700? R/mphindi. Mafotokozedwe a rotor ya graphite ndi Φ 70mm ~ 250mm, yokhala ndi zowongolera za Φ 85mm ~ 350mm, rotor yoyera kwambiri ya graphite ili ndi mawonekedwe monga mphamvu yayikulu, kukana kutentha kwambiri, komanso kukana kwa aluminium otaya dzimbiri. Pa kuyeretsedwa ndi degassing ndondomeko, nayitrogeni umayamba kuphimba pamwamba pa zotayidwa aloyi madzi mkati mwa bokosi chitetezo, kusunga poyera mbali ya graphite rotor mu mpweya inert kupewa mkulu-kutentha makutidwe ndi okosijeni wa rotor ndi kuwonjezera utumiki wake. moyo. The impeller mawonekedwe ndi streamlined, amene angathe kuchepetsa kukana pa kasinthasintha, ndi mikangano ndi kukokoloka mphamvu kwaiye pakati pa impeller ndi zitsulo zotayidwa aloyi madzi ndi ochepa. Izi zimabweretsa kuchepa kwa mpweya wopitilira 50%, kufupikitsa nthawi yosungunula, ndikuchepetsa ndalama zopangira.
