Zifukwa ndi Mayankho a Kusintha kwa Zida Zapamwamba Zozimitsa Mafupipafupi
Zifukwa ndi Mayankho a Kusintha kwa Zochita Zazikulu Zozimitsa Zambiri
Pali zida zambiri zozimitsa. Zida zozimitsa pafupipafupi komanso zapakatikati ndi chisankho chabwino cha zida. Pansi pa njira yoyenera yozimitsira, zinthu ndi zofunikira za workpiece zingayambitse mapindikidwe. Pochiza kutentha, zinthu zambiri sizimayendetsedwa bwino, ndipo workpiece idzawonongeka.
Imawongolera momwe mungathetsere kuwonongeka kwa workpiece:
Zakuthupi ndi mawonekedwe a workpiece yozimitsidwa ayenera kudziwa bwino, ndipo njira yochizira kutentha imatha kuwonetsa annealing ndiyeno kuzimitsa kwanthawi yayitali.
Kutentha kozimitsa sikuyenera kukhala kokwera kwambiri. Njira yotenthetsera iyenera kukhala yolondola komanso yoyenera. Chithandizo cha kutentha chisanadze chikhoza kuchepetsa kuthekera kwa deformation. Zida zotenthetsera kwambiri ndizofunika kwambiri pa liwiro la workpiece ndi kufanana kwa kutentha. Pa nthawi yomweyo, nthawi yozizira madzi quenching sayenera yaitali, ndi ndende ya quenching madzi ayenera kulamulidwa. Pomaliza, kuzimitsa ndi kutentha kungayambitse kusintha kwa workpiece, choncho ndi bwino kuonetsetsa kuti chithandizo chimodzi ndi choyenera.
