Msoko wolunjika chitsulo billet kuboola kutentha kumasiyanasiyana malinga ndi zopangira zachilendo zachilendo. Chitoliro chokulirapo chamafuta koma makamaka mu 1200 ℃, pomwe zinthu za kaboni ndi zinthu zina zowonjezera kutentha zimatsika pang'ono.

Chinsinsi chachiwiri ndikuyesa kuchepetsa kuchuluka kwa ntchito yotenthetsera. Makamaka mu chigongono chowotcha, chitoliro chachitsulo chowongoka cha 16Mn chosiya zinthu zomwe zimayembekezeka kukhala ndi moyo ndikukanda chitoliro chapamwamba, kuchonderera mwamphamvu kwambiri. Mu 16Mn mowongoka msoko zitsulo kupanga chitoliro, popeza ndondomeko yoyamba ndi yotentha, kotero kutentha ntchito ndi kusamvana mankhwala khalidwe ndondomeko yofunika kwambiri.

Kutentha ndi ng'anjo, malinga ndi zotsatira zawo, ndi reheating ng'anjo lagawidwa mitundu iwiri; woyamba ntchito billet mkangano kuchokera firiji kutentha processing; yotsirizira ntchito ndondomeko mu akusoweka reheated kuti chofunika processing kutentha. Kutentha kudzakhala kolakwika kunja kwa chubu pamwamba pa chubu kumatha kuwonetsa ming'alu, makwinya ndi ululu wa migraine ndi zina zotayirira. Ng'anjo Pali njira zambiri, koma ntchito yoyamba ndi ng'anjo ya mphete. Ng'anjo iyi ili ndi choyatsira cha annular, imatha kusintha pang'onopang'ono mayendedwe a m'mimba mwake mopanda kanthu pansi pa katundu kuchokera pakhomo, kutembenuka kungagwiritsidwe ntchito potulukira kutentha ndi kutentha kwamtundu wa chitofu. Opaleshoni imeneyi ndi kiyi akusowekapo ndi usavutike mtima uniformly kutentha oyenera processing. Chifukwa zimakhudza kwambiri khalidwe la perforation, ndiye, pamene kutentha kwa ndondomeko kuboola ndi chikhalidwe chofunika zimakhudza khalidwe, nthawi zambiri kutentha billet kuboola ntchito ndi kusokoneza.
