Uphuhliso lwenkqubo yokunyanga ubushushu kwintsimbi yentsimbi ye-chain ephezulu i-23MnNiMoCr54
Unyango lobushushuImisela umgangatho kunye nokusebenza kwentsimbi yekhonkco elijikelezileyo, ngoko ke inkqubo yokunyanga ubushushu efanelekileyo nesebenzayo yindlela esebenzayo yokuqinisekisa uzinzo oluhle lwentsimbi yekhonkco ekumgangatho ophezulu.
Inkqubo yonyango lobushushu lwentsimbi yentsimbi ye-23MnNiMoCr54 ephezulu
Indlela yokufudumeza ye-medium frequency induction ineempawu zesantya sokufudumeza esikhawulezayo kunye ne-oxidation encinci, engahambelani nje nemveliso eluhlaza yangoku, kodwa ikwafikelela kwii-index ezithile zamandla kunye nokuqina kwetyathanga lentsimbi ejikelezileyo. Inkqubo ethile yokwamkela unyango lobushushu be-medium frequency induction kukusebenzisa i-medium frequency induction continuous furnace yezixhobo zokufudumeza ze-induction ezinamandla aphezulu kuqala, ukuze kufezekiswe ulwahlulo lwe-round steel link quenching kunye ne-tempering chain. Ubushushu bokucima kunye ne-tempering ngaphambi kokuba ityathanga lifakwe emlilweni bulawulwa ngokungqongqo ngokulinganisa ubushushu be-infrared. Ngovavanyo olusebenzayo, kufunyaniswe ukuba i-cooling medium yokucima kunye ne-tempering ngamanzi, Ubushushu bamanzi bulawulwa ngaphantsi kwama-30 ℃. Amandla okufudumeza okucima kufuneka alawulwe phakathi kwama-25-35kw, isantya setyathanga kufuneka silawulwe kwi-8-9hz kwaye ubushushu kufuneka bulawulwe phakathi kwama-930 ℃ -960 ℃, ukuze ubunzima bomaleko oqinileyo kunye netyathanga bukwazi ukuhlangabezana neemfuno ezithile zomgangatho. Amandla okufudumeza enkqubo ye-tempering alawulwa kwi-10-20kw kwaye ubushushu bulawulwa kwi-500 ℃-550 ℃. Isantya setsheyini sigcinwa phakathi kwe-15 kunye ne-16Hz.
(1) Kwinqanaba lokuqala lokwenzauthotho lwekhonkco lwentsimbi olujikelezileyo, indlela yokunyanga ubushushu yi-radiant furnace, efana ne-rotary hearth furnace. I-convection furnace isetyenziselwa ukuthambisa. Le ndlela ifuna ixesha elide lokufudumeza kunye nokusebenza okuphantsi, ezinye zazo zikwafuna i-long traction chain. Kwinkqubo yonke yokufudumeza ye-chain, ngenxa yezinga eliphezulu le-oxidation yomphezulu, kunzima ukufumana iinkozo ze-austenite ezintle kakhulu, ekugqibeleni ezikhokelela kumgangatho jikelele we-round steel link chain eveliswa ngelo xesha. Ngophuhliso oluqhubekayo lwetekhnoloji yokunyanga ubushushu, indlela yokufudumeza ye-intermediate frequency induction ephuhliswe kwinqanaba lokugqibela isetyenziswa kakhulu, kwaye umgangatho wokunyanga ubushushu we-round steel link chain uphuculwe kakhulu.
(2) Itekhnoloji yokulungisa iintambo, ukusetyenziswa kokuqala kobushushu obufanayo, uphuhliso oluzinzileyo ngakumbi kukuthambisa ubushushu obuphakathi kunye nobushushu obufanayo kunye nobushushu obufanayo. Oko kubizwa ngokuba kukuthambisa ubushushu obufanayo kukuqwalasela ukuba ubunzima benxalenye nganye yekhonkco lekhonkco buyafana emva kokuthambisa, kodwa ikhonkco lekhonkco lenziwa ngokuthambisa. Ukuba ubushushu bokulungisa buphantsi kakhulu, ijoyinti yokulungisa iintambo kulula ukuyiqhekeza, kwaye ubunzima bekhonkco lekhonkco buphezulu, ukungqubana phakathi kwengalo ethe tye kunye nokutshintsha okuphakathi kwe-conveyor kulula kakhulu ukuvelisa iintanda. Ukuba ubushushu bokulungisa iintambo buphantsi, ubunzima bekhonkco bunokuncipha. Ukuthambisa ubushushu obuhlukeneyo kusebenzisa ukufudumeza okubangelwa kukufakelwa, okufanelekileyo ngakumbi kwiimeko zokufudumeza zekhonkco, oko kukuthi, umphezulu wegxalaba lekhonkco unobunzima obuphezulu kunye nokumelana nokuguguleka, kwaye ingalo ethe tye inobunzima obuphantsi kunye nokuqina okuhle. Le ndlela yonyango lobushushu inokuphucula kakhulu umgangatho wekhonkco.
