Izixhobo zokucima izixhobo, kutheni izixhobo kufuneka zicinyiwe?
Izixhobo zokucima izixhobo, kutheni izixhobo kufuneka zicinyiwe?
1. Ukucima izixhobo Kukuphucula kakhulu ukuqina, ubulukhuni, ukunxiba ukumelana, ukhathala amandla kunye nobulukhuni bentsimbi, ukuze kuhlangatyezwane neemfuno zokusetyenziswa ezahlukeneyo zamalungu oomatshini nezixhobo.
2. Ukucinywa kwesinyithi kukufudumeza isinyithi kubushushu obungaphezulu kobushushu obubalulekileyo be-Ac3 (i-hypoeutectoid iron) okanye i-Ac1 (intsimbi ye-hypereutectoid), yibambe kangangexesha elithile ukuyenza iphelele okanye ngokungagungqiyo, kwaye emva koko ibe kwinqanaba inkulu kunezinga elibalulekileyo lokupholisa Iqondo lokupholisa likhawuleze lipholile liye ezantsi kweNks (okanye isothermal kufutshane Nks) yenkqubo yonyango lobushushu yenguqulelo yemartensite (okanye bainite). Ngokwesiqhelo, unyango lwesisombululo sealuminium ingxubevange, ingxubevange yobhedu, titanium ingxubevange, iglasi enomsindo kunye nezinye izinto okanye inkqubo yokunyanga ubushushu ngenkqubo yokupholisa ngokukhawuleza ibizwa ngokuba kukucima.
3. Kukho izinto zoomatshini kwivili esisangqa enokuthi iqhubeke ngokugcina umnatha kwaye ihambise intshukumo namandla. Ukusetyenziswa kwezixhobo kuthumelo kwabonakala kwakusasa kakhulu. Ekupheleni kwenkulungwane ye-19, umgaqo wendlela yokusika izixhobo kunye nezixhobo ezikhethekileyo zomatshini kunye nezixhobo ezisebenzise lo mgaqo ukusika izixhobo zavela ngokulandelelana. Nophuhliso lwemveliso, ukuguda kokusebenza kwegiya kuye kwaqwalaselwa.
