Kutha kudzaza kwachitsulo chosungunuka, chomwe chimadziwikanso kuti fluidity, ndichofunikira kwambiri pakuponya. Zimatanthawuza kuthekera kwachitsulo chosungunula kudzaza nkhungu kwathunthu isanayambe kulimba. Kumvetsetsa ndi kukhathamiritsa malowa ndikofunikira kuti mupange zojambula zapamwamba zokhala ndi ma geometries owoneka bwino komanso zolakwika zochepa.
Lingaliro Loyamba la Kutha Kudzaza
Kutha kwa chitsulo chosungunuka kumatsimikizira momwe chitsulo chimalowera ndikudzaza tsatanetsatane wa nkhungu. Zimakhudzidwa ndi zinthu zingapo kuphatikizapo chitsulo, kutentha, ndi mapangidwe a nkhungu. Kutha kudzaza bwino kumatsimikizira kuti kuponya komaliza kulibe zolakwika monga misruns, kutsekeka kozizira, ndi magawo osakwanira. Katunduyu ndi wofunikira kwambiri popanga ma castings okhala ndi mipanda yopyapyala ndi zigawo zokhala ndi ma geometries ovuta.
Zinthu Zomwe Zimalimbikitsa Kutha Kudzaza
1.Metal Composition: Kapangidwe ka chitsulo chosungunula kamakhala ndi gawo lalikulu pakutulutsa kwake. Zitsulo zokhala ndi malo otsika osungunuka nthawi zambiri zimakhala ndi madzi abwinoko.
2.Kutentha: Kutentha kwachitsulo chosungunula kumagwirizana mwachindunji ndi madzi ake. Kutentha kwambiri kumachepetsa kukhuthala kwachitsulo, kumapangitsa kuti chitsulocho chizitha kulowa mu nkhungu. Komabe, kutentha kwambiri kungayambitse kuwonjezereka kwa okosijeni ndi kuyamwa kwa gasi, zomwe zingayambitse zolakwika pakuponya.
3.Mapangidwe a Mold: Mapangidwe ndi zinthu za nkhungu zimakhudza kwambiri luso lodzaza. Nkhungu yokhala ndi malo osalala komanso njira zolowera zolowera zimathandizira kuyenda bwino.
4.Kuthira Mtengo: Mlingo umene zitsulo zosungunuka zimatsanuliridwa mu nkhungu zimakhudza mphamvu yake yodzaza patsekeke. Kuthira kolamuliridwa komanso kosasinthasintha kumatsimikizira kuti chitsulocho chimakhalabe ndi kutentha kwake ndi maonekedwe ake, kuteteza kulimba msanga.
5.Zowonjezera: Zowonjezera zina zitha kuyambitsidwa kuti zithandizire kusungunuka kwachitsulo chosungunuka. Mwachitsanzo, silicon nthawi zambiri imawonjezeredwa kuzitsulo za aluminiyamu kuti ziwongolere madzimadzi, kuwapangitsa kukhala oyenera kuyika zovuta.
Njira Zopititsa patsogolo Luso Lodzaza
1.Optimal Alloy Selection: Kusankha ma aloyi okhala ndi zinthu zabwino zamadzimadzi ndi gawo loyamba pakukulitsa luso lodzaza. Mwachitsanzo, ma aluminiyamu-silicon alloys amakondedwa chifukwa chamadzimadzi ake apamwamba komanso osavuta kuponyera.
2.Kuwongolera Kutentha: Kusunga kutentha kwabwino kwachitsulo chosungunula panthawi yonseyi ndikofunika kwambiri. Kutenthetsa nkhungu ndikuwongolera kutentha kothira kumatha kupititsa patsogolo madzi. Kugwiritsa ntchito njira zowunikira kutentha kumathandiza kupeza zotsatira zofananira.
3.Kupititsa patsogolo Mold Design: Kupanga zisankho zokhala ndi malo osalala, mpweya wokwanira, ndi njira zoyendetsera bwino zomwe zimathandizira kuti zitsulo ziziyenda bwino.
4.Kugwiritsa Ntchito Inoculants ndi Fluxes: Kuonjezera ma inoculants kungathe kuyeretsa zitsulo zachitsulo, ndikuwongolera madzi ake. Fluxes itha kugwiritsidwanso ntchito kuchotsa zonyansa ndikuchepetsa kugwedezeka kwapamtunda, kukulitsa mawonekedwe otaya achitsulo chosungunuka.
5.Degassing: Kuchotsa mpweya wosungunuka muzitsulo zosungunuka kumatha kulepheretsa mapangidwe a thovu ndi voids, kupititsa patsogolo luso lodzaza.
6.Njira Zothirira Zoyendetsedwa: Kugwiritsa ntchito makina otsatsira okha kumapangitsa kuti chitsulo chosungunula chikhale chokhazikika komanso chowongolera mu nkhungu. Izi zimachepetsa mwayi wa chipwirikiti ndi kuzimitsa kuzizira, zomwe zimapangitsa kuti pakhale kudzaza bwino.
