Silicon Kwa Kuponya Kwachitsulo

Kuponyera zitsulo ndi njira yakale yomwe yakhala yofunika kwambiri pa chitukuko cha anthu kwa zaka zambiri. Kuchokera pakupanga ziboliboli zovuta kwambiri mpaka kupanga magawo ovuta a mafakitale, kupanga zitsulo kumagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana.Silikoni, chinthu chomwe nthawi zambiri chimagwirizanitsidwa ndi zipangizo zamakono, ndi chimodzi mwa zinthu zothandiza kwambiri kwa anthu. Nthawi zambiri amagwiritsidwa ntchito kupanga aluminiyamu-zitsulo za siliconndiferrosilicon(chitsulo-silicon) aloyi, imakhalanso ndi mphamvu yaikulu pazitsulo zoponyera zitsulo. China, Russia, Norway, ndi Brazil ndi omwe amapanga mchere wambiri wa silicon. M'nkhaniyi, tiwona momwe silicon imagwiritsidwira ntchito popanga zitsulo, kufufuza zomwe zili, ntchito zake, ndi njira zomwe zimakulitsira kuponyera.

Kumvetsetsa Silicon mu Metal Casting

Silicon ndi chinthu chosunthika chomwe chimagwiritsidwa ntchito kwambiri popanga zitsulo chifukwa cha mawonekedwe ake apadera. Ikaphatikizidwa ndi zitsulo monga aluminiyamu, mkuwa, ndi chitsulo, silikoni imawonjezera mphamvu, kuuma, ndi kukana dzimbiri kwa aloyiyo. Makina opangidwa bwinowa amapangitsa ma alloys a silicon kukhala ofunika kwambiri m'mafakitale omwe kulimba ndi magwiridwe antchito ndikofunikira.

Chifukwa chiyani Silicon Ndi Yoyenera Kuponyera Zitsulo

High Melting Point: Silicon ili ndi malo osungunuka kwambiri, omwe amachititsa kuti ikhale yoyenera kugwiritsira ntchito kutentha kwakukulu monga kuponya zitsulo.
Kukula Kwamafuta Otsika: Silicon ili ndi malo otsika owonjezera kutentha, omwe amathandiza kuchepetsa chiopsezo cha kutentha kwa kutentha panthawi yoponya.
Madzi abwino: Silicon imapangitsa kuti chitsulo chosungunula chisasunthike, ndikupangitsa kuti chiziyenda mosavuta mu nkhungu ndi mapanga ovuta.
Mphamvu zowonjezera: Silicon imawonjezera mphamvu ndi kuuma kwazitsulo zazitsulo, zomwe zimawapangitsa kukhala abwino kwa mapulogalamu omwe amafunikira makina apamwamba kwambiri.

Kugwiritsa ntchito Silicon mu Metal Casting

1. Kuponya kwa Aluminium: Silikoni imagwiritsidwa ntchito kwambiri popanga aluminiyamu kuti apititse patsogolo makina a alloy. Ma aluminiyamu-silicon aloyi ndi opepuka ndipo ali ndi kukana kwa dzimbiri, kuwapangitsa kukhala abwino kwazamlengalenga ndi ntchito zamagalimoto.

2. Kuponya Chitsulo: Mu chitsulo choponyedwa, silicon imawonjezedwa ku chitsulo cha imvi kuti ipititse patsogolo mapangidwe a ma graphite flakes, omwe amachititsa kuti zinthuzo zikhale zosavuta komanso zowonongeka. Silicon imathandizanso kukana kuvala kwa ferroalloys.

3. Cast Steel: Silikoni amagwiritsidwa ntchito muzitsulo zotayidwa kuti asungunuke chitsulo chosungunuka ndikuwongolera madzi ake. Silicon imathandizanso kuwongolera kukula kwa chitsulo, zomwe zimapangitsa kuti zitsulo zikhale zolimba komanso zosinthika.

Udindo wa Silicon Pakukulitsa Njira Yoyimba

Kupititsa patsogolo fluidity: Silicon imapangitsa kuti chitsulo chosungunula chisasunthike, kuti chizitha kudzaza mosavuta mapanga ovuta. Katunduyu ndi wofunikira kuti mukwaniritse zojambula zovuta komanso zatsatanetsatane.

Kuchepetsa Shrinkage: Kuwonjezera silicon kuzitsulo zazitsulo kumathandizira kuchepetsa kuwonongeka kwa shrinkage mu castings, kuonetsetsa kulondola kwazithunzi ndi kuchepetsa kufunika kwa makina owonjezera.

Kuwonjezera Machinability: Machinability n'zosavuta pokonza. Katunduyu ndiwothandiza makamaka pamapulogalamu omwe amafunikira makina opangira ma post-casting.

Mavuto ndi Kuganizira

Ngakhale silicon imapereka zabwino zambiri pakuponya zitsulo, palinso zovuta zina zomwe muyenera kuziganizira:

1. Brittleness: Kuchuluka kwa silicon kungayambitse kuwonongeka kwa alloy, zomwe zingasokoneze makina ake. Kapangidwe koyenera ka aloyi ndi kuwongolera zinthu za silicon ndizofunikira kuti tipewe vutoli.

2. Porosity: Ngati sichiyendetsedwa bwino, silicon ikhoza kuonjezera chiopsezo cha porosity mu castings. Makina osamala komanso njira zowongolera bwino ziyenera kuchitidwa kuti muchepetse porosity.

3. Mtengo: Silicon ndi chinthu chokwera mtengo chomwe chimakhudza mtengo wonse wopangira ma alloys okhala ndi silicon. Kusanthula kwamtengo wapatali ndikofunikira kuti mudziwe kuthekera kogwiritsa ntchito silicon mu pulogalamu inayake yoponya.
