Black annealed mosamalitsa kulankhula osati annealing wamba, koma ndondomeko ndi annealing pafupifupi.Chitoliro chakuda chachitsulokhungu ndi black oxide!

Annealing: annealing zitsulo aloyi ndi kutenthedwa ndi kutentha koyenera ndi kusunga nthawi, ndiyeno pang'onopang'ono kuzirala kutentha ndondomeko.Annealed zitsulo ndi bungwe hypoeutectoid ferrite pepala pearlite;Eutectoid chitsulo kapena eutectoid chitsulo ndi granular ngale.Mwachidule, bungwe la annealing lili pafupi ndi bungwe logwirizana.

Cholinga cha annealing

①kuchepetsa kuuma zitsulo, bwino ductility, kuti atsogolere kudula ndi kuzizira mapindikidwe processing.

②kuyenga tirigu, kuthetsa kuponyera, forging, kuwotcherera zolakwika chifukwa cha bungwe, bungwe ndi zikuchokera homogeneous zitsulo, zitsulo kusintha ntchito kapena wotsatira kutentha mankhwala kukonzekera minofu.

③kuthetsa kupsyinjika kwamkati muzitsulo kuti muteteze deformation ndi kusweka.
