Uphuhliso lwenkqubo yokunyanga ubushushu kwibakala eliphezulu lentsimbi yentsimbi 23MnNiMoCr54
Unyango lobushushuimisela umgangatho kunye nokusebenza kwentsimbi ejikelezayo yekhonkco yekhonkco, ngoko ke inkqubo efanelekileyo kunye neyonyango yokushisa ukushisa yindlela efanelekileyo yokuqinisekisa ukuzinza okulungileyo kwentsimbi ye-high-grade chain.
Inkqubo yokunyanga ukushisa kwe-23MnNiMoCr54 yentsimbi yentsimbi ephezulu
Indlela yokufudumala ephakathi kwe-frequency induction ineempawu zesantya sokufudumeza ngokukhawuleza kunye ne-oxidation encinci, engahambelani kuphela nemveliso eluhlaza yangoku, kodwa ifikelela kwizalathisi ezithile zamandla ekhonkco yentsimbi ejikelezayo kunye nokuqina.Inkqubo ethile yokwamkela unyango lobushushu obuphakathi ngamaza aphakathi kukwamkela i-medium frequency induction eqhubekayo eziko lezixhobo zokufudumeza zamandla aphezulu kuqala, ukuqonda ulwahlulo lwentsimbi engqukuva yokucinywa kwekhonkco kunye nobushushu.Ukucima kunye neqondo lokushisa ngaphambi kokuba ikhonkco lifakwe emlilweni lilawulwa ngokungqongqo ngumlinganiselo wobushushu be-infrared.Ngokusebenzisa uvavanyo ekusebenzeni, kufunyenwe ukuba indawo yokupholisa yokucima kunye nokufudumeza ngamanzi, Ubushushu bamanzi bulawulwa ngaphantsi kwe-30 ℃.Amandla okucima ukufudumeza kufuneka alawulwe phakathi kwe-25-35kw, isantya sekhonkco kufuneka silawulwe kwi-8-9hz kwaye iqondo lokushisa kufuneka lilawulwe phakathi kwe-930 ℃ -960 ℃, ukwenzela ukuba ukuqina kobulukhuni kunye nekhonkco kunokwanelisa iimfuno ezithile zomgangatho. .Amandla okufudumeza inkqubo yobushushu ilawulwa 10-20kw kwaye ubushushu ilawulwa 500 ℃-550 ℃.Isantya setsheyini sigcinwa phakathi kwe-15 kunye ne-16Hz.
(1) Kwinqanaba lokuqala lokwenzaikhonkco yentsimbi ejikelezayo, indlela yokunyanga ubushushu sisithando somlilo esikhazimlayo, njengesithando somlilo esijikelezayo.I-oven convection isetyenziselwa ukuthambisa.Le ndlela idinga ixesha elide lokufudumeza kunye nokusebenza okuphantsi, ezinye zazo ezifuna ikhonkco elide lokutsala.Kuyo yonke inkqubo zokufudumeza ityathanga, ngenxa iqondo eliphezulu oxidation umphezulu, kunzima ukufumana iinkozo entle kakhulu austenite, nto leyo ekugqibeleni ekhokelela kumgangatho jikelele wekhonkco ikhonkco intsimbi engqukuva eveliswe ngelo xesha.Ngophuhliso oluqhubekayo lwetekhnoloji yonyango lobushushu, indlela yokufudumeza yokwenziwa kwamaxesha aphakathi ephuhliswe kwinqanaba lamva isetyenziswa kakhulu, kwaye umgangatho wonyango wobushushu wekhonkco lentsimbi engqukuva uphuculwe kakhulu.
(2) Itekhnoloji yokuthambisa ikhonkco, ukusetyenziswa kokuqala kobushushu obufanayo, obukhoyo.uphuhliso oluzinzileyo lubushushu obuphakathi obahlukeneyo obahlukeneyo kunye nobushushu obufanayo kunye nokwahluka kobushushu bobushushu.Into ebizwa ngokuba yi-uniform heat tempering kukuqwalasela ukuba ubulukhuni becandelo ngalinye lekhonkco lekhonkco lifanayo emva kokufudumala, kodwa ikhonkco lekhonkco lenziwa ngokudibanisa.Ukuba ubushushu bobushushu buphantsi kakhulu, ijoyinti yokuwelda kulula ukuphuka, kwaye ubulukhuni bekhonkco lekhonkco buphezulu, ukukhuhlana phakathi komphandle wengalo ethe tye kunye nokutshintsha okuphakathi komhambisi kwakhona kulula kakhulu ukuvelisa iintanda.Ukuba ubushushu bobushushu buphantsi, ukuqina kwekhonkco kungancitshiswa.Ubushushu obahlukeneyo bobushushu buthatha ukufudumeza kwe-induction, okulungele ngakumbi iimeko zokufudumeza kwekhonkco, oko kukuthi, umphezulu wegxalaba lekhonkco linobulukhuni obuphezulu kunye nokumelana nokunxiba, kwaye ingalo ethe tye inobulukhuni obuphantsi kunye nokuqina okuhle.Le ndlela yonyango lokushisa inokuphucula kakhulu umgangatho wekhonkco.
