Ziziphi iimfuno ezikhethekileyo zokuqiniswa kwe-induction for steel?
Kukho ngokubanzi ezi mfuno zilandelayo zentsimbi ukunyanzeliswa.
(1) Umxholo wekhabhoni wensimbi unqunywe yimeko yokusebenza yamacandelo, anokuthi asuse kwi-0.15% ukuya kwi-1.2%. Le yeyona mfuno isisiseko kwaye iimfuno zenkqubo zinokufezekiswa ngokufudumeza kwe-induction.
(2) Intsimbi kufuneka ibe nokuthambekela ukuba iinkozo austenite akukho lula ukukhula. Ngokuqhelekileyo, ixesha lokufudumala kwe-induction lifutshane, kwaye iinkozo akulula ukukhula, kodwa ubushushu bokufudumala buphezulu.
(3) Intsimbi kufuneka ibe nesakhiwo esilungileyo kunye nesifanayo sokuqala kangangoko kunokwenzeka. Intsimbi inokufumana i-grains ye-austenite efanelekileyo kunye nobushushu obuphezulu obuvumelekileyo bokufudumala xa ukufudumala, okubaluleke ngakumbi xa ukufudumala kwe-induction, kuba ukufudumala kwe-induction kunzima kakhulu ukulawula ukucaciswa kweqondo lokushisa ngokuchanekileyo kunokufudumala kwesithando somlilo, kwaye ukushisa okufudumele kuphezulu. phezulu.
(4) Kwi-induction jikelele yokuqina kwentsimbi, kungcono ukulawula ubungakanani beenkozo kwibanga lesi-5 ukuya kwe-8.
(5) Umxholo okhethiweyo wekhabhoni. Kwezinye iindawo ezibalulekileyo ezifana ne-crankshafts, i-camshafts, njl., Xa ukhetha amabakala ensimbi, iimfuno ezongezelelweyo zomxholo wekhabhoni okhethiweyo zihlala zibekwe phambili. I-Steel 0.42% ~ 0.50%) iyancipha ukuya kwi-0.05% yoluhlu (olufana ne-0.42% ~ 0.47%), enokunciphisa impembelelo yeenguqu kwi-carbon content kwi-cracks okanye utshintsho kwi-hardened layer deep.
- Iimfuno ezinzulu zomaleko we-decarburization yentsimbi ebandayo. Xa intsimbi ebandayo isetyenziselwa ukuqina kwe-induction, kukho iimfuneko zobunzulu boluhlu olupheleleyo lwe-decarburization phezu komhlaba. Ngokubanzi, ubunzulu bubonke bomaleko we-decarburization kwicala ngalinye bungaphantsi kwe-1% yedayamitha yebha okanye ubukhulu bepleyiti yentsimbi. Ubunzima be-carbon-depleted layer emva kokucima buphantsi kakhulu, ngoko ke intsimbi epholileyo ebandayo kufuneka ikhutshwe kwi-carbon-depleted layer ngaphambi kokuvavanya ukuqina kokucima.
