Zisanu ndi chimodzi castings zilema wamba 'zimayambitsa ndi kupewa njira, osati kusonkhanitsa adzakhala chitayiko chanu! (Gawo 2)
Tipitiliza kukudziwitsani za mitundu itatu ina ya kuponya zolakwika ndi njira zothetsera.
4 Mng'alu (wotentha, mng'alu wozizira)
1) Mawonekedwe: Maonekedwe a mng'alu ndi wokhotakhota wowongoka kapena wosakhazikika, pamwamba pa mng'alu wotentha amakhala ndi oxidized mdima wandiweyani kapena wakuda komanso wopanda zitsulo zonyezimira, kung'ambika kozizira kumakhala koyera komanso kowala zitsulo. Ming'alu yakunja ya kuponya imatha kuwoneka mwachindunji koma ming'alu yamkati iyenera kugwiritsa ntchito njira zina. Ming'alu nthawi zambiri kugwirizana ndi zilema monga porosity ndi slag, zinachitika poponya mkati ngodya, mphambano makulidwe gawo, kuthira riser ogwirizana ndi kuponya chigawo otentha.
2) Zomwe Zimayambitsa: Kuponyedwa kwachitsulo kumapangitsa kuti pakhale zolakwika, chifukwa nkhungu yachitsulo yokhayokha silololedwa, kuziziritsa mofulumira kumabweretsa kupsinjika kwakukulu pakuponyedwa. Kutsegula koyambirira kwambiri kapena mochedwa kwambiri, kutsanulira ngodya kumakhala kochepa kwambiri kapena kwakukulu kwambiri, wosanjikiza wa penti ndi woonda kwambiri ect zonse zingayambitse kusweka. Mng'alu wa nkhungu wokha ukhoza kuyambitsa ming'alu.
3) Momwe mungapewere:
Ine kulabadira luso structural kotero kuponyera khoma makulidwe m'malo osiyana akhoza kusintha uniformly pogwiritsa ntchito oyenera kuzungulira kukula.
I Kusintha makulidwe a zokutira kuti zida zonse zoponyera zifike pakufunika kuziziritsa momwe mungathere kuti mupewe kupsinjika kwambiri pakuponya.
Ine Kulamulira zitsulo nkhungu kutentha, kusintha nkhungu angatenge ndi yake pachimake akulimbana, kuchotsa castings ozizira pang`onopang`ono.
5 Cold shut (kuphatikiza koyipa)
1) Mawonekedwe: Kutsekeka kozizira ndi msoko kapena ming'alu ya pamwamba yokhala ndi mbali zozungulira, idasiyanitsidwa ndi okusayidi ndi kuphatikiza kosakwanira, zotsekera zozizira kwambiri zomwe zidakhala "zochepa" . Zotsekera zozizira nthawi zambiri zimawonekera pakhoma lakumtunda kwa zoponya, zopyapyala zopingasa kapena zoyima, kulumikizana kwa makoma okhuthala ndi opyapyala, kapena pamapanelo owonda.
2) Zifukwa:
Ine Utsi kamangidwe ka zitsulo nkhungu si wololera
I Kutentha kwa ntchito ndikotsika kwambiri.
I Kupaka utoto wabwino ndi woyipa (wopangidwa ndi anthu kapena zida).
I Malo othamanga omwe adapangidwa sioyenera.
Ine Kuthira liwiro kumachedwa kwambiri ndi zina zotero.
3) Momwe mungapewere
I Mapangidwe olondola a othamanga ndi makina otulutsa mpweya.
I Large-dera la woonda khoma castings, zokutira sayenera woonda kwambiri ndi zoyenera thickening zokutira kuti akamaumba mosavuta.
I Kuti moyenerera kuonjezera nkhungu ntchito kutentha.
Ndikugwiritsa ntchito njira yothira motsata.
I Kugwiritsa ntchito makina kugwedera zitsulo kuponyera kutsanulira.
6 Bluster (dzenje la mchenga)
1) Zowoneka: Mabowo okhazikika amakhala pamalo oponyera kapena mkati, amafanana ndi mchenga, wowoneka pamwamba pomwe mutha kutulutsa njere zamchenga. Mabowo angapo amchenga amakhalapo nthawi imodzi ndipo pamwamba pake ndi mawonekedwe a peel lalanje.
2) Zifukwa:
I Mchenga pachimake pamwamba kugwa mchenga anali wokutidwa zitsulo ndi kuponya pamwamba kupanga dzenje.
Mphamvu ya pamwamba ya mchenga si yabwino, yopsereza kapena yosachiritsika.
Ine Kukula kwa mchenga pachimake ndi kunja nkhungu sizikufanana, pamene nkhungu clamping wosweka mchenga pachimake.
I Mould yoviikidwa m'madzi amchenga a graphite.
I Sands kuchokera ku sand core friction mu ladle& runner akugwera m'bowo ndi zitsulo zamadzimadzi.
3) Momwe mungapewere:
Ine Kupanga mchenga pachimake mosamalitsa malinga ndi ndondomeko ndi fufuzani khalidwe.
I Kuti ndifanane pakati pa mchenga ndi kukula kwa nkhungu yakunja.
I Kuyeretsa madzi a graphite munthawi yake.
Ine Kupewa ladle ndi mchenga pachimake mikangano.
I Kutsuka mchenga mu nkhungu poika phata la mchenga.
