Nakong ea 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 mosebetsing oohle, ka nako e telele, mokhoa oa ho boloka matla a ho phekola mocheso oa forging e bile bothata bo boima.

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 process.According ea setso austenitic khopolo-taba, ho forging lokela ho ba le nako e telele insulation tshebetso ya ho futhumatsa, e le ho tlatsa nucleation le kgolo ya dikokwana-hloko tsa austenisoal le ho hōla ha lijo-thollo tsa austenisoal. ea austenitic.Thekhenoloji 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 hlokehang ke homogenization ea sebopeho sa austenitic, eseng feela ho ka boloka 20% -30% ea matla, ho fokotsa ts'ebetso ea tlhahiso ea 302%, ho fokotsa ts'ebetso ea 30% le ho fokotsa ts'ebetso ea tlhahiso ea 302%. 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. 100mm, ho futhumatsa sebōping sa moea, mocheso oa holim'a metsi le mokokotlo o batla o fihlile ka nako e le 'ngoe, kahoo nako ea eona ea junifomo e ka hlokomolohuoa, ha e bapisoa le mokhoa oa setso oa tlhahiso (r = aD) o nang le mocheso o moholo oa ho futhumatsa, o ka fokotsoa ka hoo e ka bang 20% ​​-25% ho tima nako ea ho futhumatsa.

Tlhahlobo ea theory 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 tšepe, ts'ebeliso ea ts'ebetso ea "zero insulation" e ka netefatsa thepa ea mochini ea litlhoko; "zero insulation" ho futhumatsa ho feta mocheso oa setso o ka boloka nako ea ho futhumatsa e ka bang 50%, chelete eohle ea ho boloka matla ea 10% -15%, e ntlafatsa katleho ea 20% -30%, ka nako e ts'oanang "zero insulation" mokhoa oa ho tima o thusa ho hloekisa lijo-thollo, ho ntlafatsa matla.
