Ukadaulo wa makina opangira zitsulo zamtengo wapatali ndi njira yotenthetsera ndi kusungunula zinthu zamtengo wapatali monga golide, siliva, platinamu, palladium, ndi zina zotero, kukhala madzi kenako nkuzitsanulira mu nkhungu kapena mitundu ina kuti apange zinthu zosiyanasiyana. Ukadaulo uwu umagwiritsidwa ntchito kwambiri popanga zodzikongoletsera, kupanga ndalama, ntchito za mano ndi kupanga mafakitale.
Pali mitundu yosiyanasiyana ya makina oponyera omwe angagwiritsidwe ntchito pa ntchitoyi. Omwe amagwiritsidwa ntchito kwambiri ndi awa:
1. Makina Oponyera a Centrifugal: Makinawa amagwiritsa ntchito mphamvu ya centrifugal kuti apangitse chitsulo chosungunukacho kukhala mawonekedwe omwe akufuna mwa kuchizunguliza mofulumira kwambiri pamene akuchitsanulira mu chikombole.
2. Makina oponyera mpweya m'chidebe: Makina awa amachotsa mpweya mu chidebecho asanadzaze ndi chitsulo chosungunuka pansi pa mphamvu ya vacuum kuti atsimikizire kuti chimatha bwino popanda thovu la mpweya kapena zinyalala.
3. Ma Induction Melting Furnaces: Ma induction awa amagwiritsa ntchito electromagnetic induction kuti atenthe ndikusungunula zitsulo zomwe zili mkati mwa crucible zisanatsanuliridwe mu nkhungu kapena mawonekedwe ena.
4. Makina Opangira Utsi wa Arc Furnace (EAF): Mtundu uwu wa makina umagwiritsa ntchito arc yamagetsi pakati pa ma electrode awiri omwe amapanga kutentha kwakukulu komwe kumasungunula zinthu zopangira monga zitsulo zotsalira kapena ma alloy mwachangu mokwanira kuti apange mphamvu zambiri popanda kugwiritsa ntchito mphamvu zambiri poyerekeza ndi zina monga uvuni woyendetsedwa ndi gasi.
Ponseponse, ukadaulo wa makina opangira zitsulo zamtengo wapatali umagwira ntchito yofunika kwambiri popanga zodzikongoletsera zapamwamba komanso kuchepetsa zinyalala ndikuwonjezera magwiridwe antchito. Zimafunikira akatswiri aluso omwe amamvetsetsa momwe makinawa amagwirira ntchito limodzi ndi njira zotetezera zomwe zimafunikira kuti azigwiritse ntchito bwino kuti apewe ngozi zomwe zingachitike panthawi yogwira ntchito yokhudza malo otentha komwe kuli zoopsa zamoto ngati njira zodzitetezera sizitengedwa mozama.
