Phekolo ea mocheso ea ho forging, ka lebaka la matla a maholo a sebōpi se futhumatsang le nako e telele ea ho kenya letsoho, tšebeliso ea matla e kholo haholo ts'ebetsong eohle, ka nako e telele, mokhoa oa ho boloka matla a ho phekola mocheso oa ho forging o bile teng. bothata bo boima.

Seo ho thoeng ke "zero insulation" quenching, ke ho supa ho forging futhumatsang, bokaholimo ba eona le mantlha ho fihla quenching futhumatsang mocheso, ha ho insulation, hang-hang quenching tsidifatso tshebetso.Ho ea ka khopolo ea setso austenitic, forging lokela ho ba le nako e telele. nako ea ho kenya letsoho ts'ebetsong ea ho futhumatsa, e le ho phethela nucleation le kholo ea lithollo tsa austenitic, ho qhibiliha ha cementite e setseng le homogenization ea austenitic.Theknoloji ea hona joale ea ho tima le ho futhumatsa ea forgings e hlahisoa tlas'a tataiso ea khopolo ena.Ha e bapisoa le ts'ebetso ea hona joale ea ho tima, "ho boloka mocheso oa zero" ho tima ho boloka nako ea ho boloka mocheso o hlokoang ke homogenization ea sebopeho sa austenitic, eseng feela ho ka boloka 20% -30% ea matla, ho ntlafatsa katleho ea tlhahiso ea 20% -30%, empa hape ho ka fokotsa kapa ho felisa mefokolo ea oxidation, decarbonization, deformation joalo-joalo, e leng se loketseng ho ntlafatsa boleng ba sehlahisoa.

Ha tšepe ea carbon le tšepe e tlaase ea alloy e futhumetse ho Ac1 kapa Ac2, mokhoa oa homogenization oa austenite le ho qhibiliha ha carbides ka pearlite li potlakile. Thermal insulation, ke hore, ho fihlela zero thermal insulation quenching.Ka mohlala, ha bophara kapa botenya ba 45 tšepe workpiece e seng ho feta 100mm, ho futhumatsa ka sebōpi sa moea, mocheso oa holim'a metsi le mokokotlo o batla o fihlile ho ka nako e ts'oanang, kahoo nako ea eona ea junifomo e ka hlokomolohuoa, ha e bapisoa le mokhoa oa setso oa tlhahiso (r = aD) o nang le coefficient e kholo ea ho futhumatsa, e ka fokotsoa ka hoo e ka bang 20% ​​-25% ea ho tima nako ea ho futhumatsa.

Tlhahlobo ea maikutlo le liphetho tsa liteko li bonts'a hore hoa khoneha ho amohela "zero insulation" ho tima le ho futhumatsa mocheso o tloaelehileng oa tšepe ea sebopeho. Haholo-holo, 45, 45 mn2 carbon structural steel kapa single element alloy structural steel, tšebeliso ea "zero insulation" ts'ebetso e ka netefatsa thepa ea mochini ea litlhoko; 45, 35CrMo, GCrl5 le lisebelisoa tse ling tsa tšepe tsa sebopeho, tšebeliso ea "zero insulation" ho futhumatsa ho feta mocheso oa setso o ka boloka nako ea ho futhumatsa ea hoo e ka bang 50%, chelete eohle ea ho boloka matla a 10% - 15%, ho ntlafatsa katleho ea 20% -30%, ka nako e ts'oanang "zero insulation" ts'ebetso ea ho tima e thusa ho hloekisa lijo-thollo, ho ntlafatsa matla.
