Idatha yokuba isithando sokufudumala se-induction kufuneka silawule kwi-forging

1. Injongo yobushushu bokuqala bokubumba i-induction yokufudumeza i-furnace yokufudumeza i-blank kukunyusa ubushushu be-formed blank, ukwenzela ukuba i-carbon kunye ne-nitrogen compounds ye-V, i-Nb kunye ne-Ti inokunyibilika ngokuthe ngcembe kwi-austenite, kunye nenkulu enkulu. ubungakanani bekhabhoni enyibilikisiweyo ene-microalloyed kunye ne-nitrogen compounds Imvula ngexesha lenkqubo yokupholisa inokuphucula amandla kunye nobunzima bentsimbi; kwelinye icala, njengoko iqondo lokushisa lisanda, iinkozo ze-austenite zikhula, isakhiwo siyancipha, kwaye ubunzima buyancipha.

2. Injongo yobushushu bokugqibela bokubumba ukufudumeza indawo engenanto kwisithando sokufudumala se-induction kukulawula ngokufanelekileyo ubushushu obuphantsi bokugqibela bokubumba, obunokunyusa iqondo lokuqhekeka kwengqolowa, ukwandisa inani lemida yengqolowa, ukuvelisa ngokufanelekileyo imvula eyenziwe yi-deformation-induced precipitation. kwaye usasaze amaqhekeza, kwaye ngexesha elifanayo, amandla okuqhuba i-recrystallization encinci. , ukucocwa okuziinkozo, kukulungele ukuphucula ukuqina.

3. Isixa se-deformation kunye nesantya sokuguqulwa kwe-blank eshushu ngokufudumeza isithando somlilo se-induction iphinda ibe yinto yokuqhekeka kweenkozo ze-austenite ze-blank, kunye ne-recrystallization ye-austenite coarse grains ibe yi-fine grains. Isakhiwo sokuguqulwa kwesigaba esihle se-ferrite sisasazwa ngokulinganayo kwisakhiwo, esinenzuzo ekuphuculeni ukuqina kwentsimbi.

4. Isantya sokupholisa emva kokupholisa kwe-blank blank kwi-induction yokufudumala isithando somlilo sinempembelelo enkulu ekusebenzeni kwe-forging, eyona nto ibalulekileyo ekuqinisekiseni ubume be-metallographic kunye neempawu zomatshini zokubumba. Ekubeni ukuguqulwa kwesigaba ngexesha lenkqubo yokupholisa kunzima, ukupholisa kwendalo akukwazi ukulawula ngokufanelekileyo ukungacimi kunye nokufudumala. Umgangatho wentsimbi kufuneka unikezwe isixhobo sokupholisa esingachaphazeli ixesha. Enyanisweni, ukulawulwa kokupholisa kwi-800 ° C ~ 500 ° C kunempembelelo kumandla kunye nokuqina kwentsimbi, kwaye ukupholisa ngaphandle kolu luhlu akubalulekanga. Ulawulo olululo lomlinganiselo wokupholisa luchaphazela ngokuthe ngqo ulwakhiwo lwe-metallographic kunye neempawu zoomatshini bokubumba, ngoko ke kufuneka kusekelwe kwiintsimbi ezahlukeneyo ezingacinywanga kunye nezobushushu ukuze kufumaneke iqondo lokupholisa elilawulwa yi-post-forging elifanelekileyo ngokusebenzisa imifuniselo.

Okwangoku, idatha ekufuneka ilawulwe ekubunjweni kwesithando sokufudumala se-induction ixhalabile ngakumbi kwaye ixabiswa ngamashishini. Kuphela ngokunikela ingqalelo ngokwenene kubushushu bokufudumala kweziko lokufudumeza lokungenisa i-induction enokuqinisekiswa ukubunjwa okuqhelekileyo, ukusebenza kakuhle kokuveliswa kwemveliso kunokuphuculwa, kwaye iindleko zemveliso zinokuncitshiswa.
