Uhlalutyo lonyango lobushushu kunye nesisombululo se-ductile

Ukongeza kwi-act yentsimbi yentsimbi yokubola i-iron ye-carbonition kwigrafu ye-flocceles, enye kukutshintsha intsebenzo yentsimbi, enye kukuphelisa uxinzelelo lokuphosa. Kufanelekile ukuba uqaphele ukuba unyango lobushushu lokuphosa alunakutshintsha ubume be-prographicite yohlobo olokuqala kunye nokusasazwa kwengubo, oko kukuthi, ubungakanani besixhobo, isabelo asiyi kutshintsha.
I-1. I-Dactile ye-Iron
Kwinkqubo yokuphosa, isantya esipholileyo se-iron yentsimbi yahlukile kumphezulu, senza uxinzelelo lwangaphakathi lokuphosa. Ukuba ayipheli, iyakwenza iinxalenye ezinobungozi okanye iqhume kwinkqubo yokusika kunye nokusetyenziswa. Ukukhupha uxinzelelo, ukwaluphala kunye nokwaluphala kwendalo kuhlala kusetyenziswa. Fudumeza ukuphosa malunga ne-500 ~ 560 isigameko sexesha elithile, emva koko ususe ukuphosa kunye nezomlilo kubanda. Olu gadalala luphawu lokwaluphala. Ukuguga kwendalo kukugcina intsimbi ngaphandle kweenyanga ezi-6 ~ 18 ukukhulula uxinzelelo ngokwemvelo, kodwa kungasetyenziswanga ngenxa yexesha elide kunye nokusebenza kakuhle.
2. Ukuphucula intsebenzo iyonke yenxalenye yentsimbi yentsimbi ngeenjongo zonyango lobushushu
Ukwenzela ukuphucula ukusebenza kwentsimbi iyonke, idla ngokuphelisa umlomo omhlophe kukuthi, ukuphucula ubunzima bentsimbi, phucula amandla entsimbi, phucula amandla entsimbi yentsimbi, ukunqunyulwa, njl njl.
(1). Phucula amandla entsimbi ye-ductile ngokuvuma kakuhle
Injongo ye-gucile intsimbi kukuguqula izicubu ze-matrix kwi-pearlite ye-pearlite entle. Inkqubo yeyokuhlambela i-ductile inyibiliki ye-ructile ye-ferrite kunye nePearlite kwiqondo lokushisa eliyi-850-9-900, i-fearrite yantlandlolo iguqulwa yaba yi-austedite, kwaye igrafu ye-ferite ichithwe kwi-austedite. Emva kokufakelwa, i-austedite yomoya epholileyo iguqulwa yaba yinyama entle, anda amandla okuphosa.
(2). Ukuphucula ubunzima bentsimbi ye-ductile
Kwinkqubo yokuphosa, i-iron ye-mpuby eqhelekileyo imbi ngakumbi, kwaye ikwanoxinzelelo lwangaphakathi. Intsimbi yentsimbi inzima ukufumana umzimba ococekileyo yentsimbi okanye i-peartetic matrix. Ukwenzela ukuphucula ixesha okanye ubunzima besinyithi, intsimbi yentsimbi ihlala iphinde yafunyanwa nge-900-550 isidanga kunye nexesha elaneleyo lokuthambisa iqondo lokushisa eliphezulu, kwaye emva koko isithando somlilo sipholile. Kule nkqubo, i-carburite kwi-matrix ibongoza igrafu, kwaye igrafu ivela kwi-austedite. Le ngxaki iqokelela igrafu yentsusa ye-SPRIX, kwaye iMatrix iguqulwe ngokupheleleyo ibe yi-FRRT.
Ukuba izicubu ezihlangeneyo zenziwe (i-Ferrite + i-Matrix) i-Matrix kunye ne-Spherical igrafu, ukuze ziphucule ubunzima, kufuneka siyenze i-odolo ye-carbrite kwi-pearlite kwaye iguqule i-ferrite kunye ne-phrite. Ngesi sizathu, intsimbi yentsimbi iphinde yaphinda yafunyanwa kubushushu beqondopocipiction lama-700-760 isidanga kunye nezixhobo zipholile kwaye zipholile.
(3). I-isothermal ukucima unyango lwe-ductile
INJONGO YOKUGQIBELA YOKUGQIBELA I-STARMCHING YOKUGQIBELA I-SURCCIle yentsimbi kukuguqula izicubu ze-matrix iphoswe kwizicubu eziphantsi zentsimbi, umda onamandla wempembelelo ye-AK 32J. Inkqubo yonyango yile: Fumana i-iron yamandla amakhulu.
Unyango olungentla lwentsimbi lubonisa ukuba unyango lobushushu lwe-iron yentsimbi inokutshintsha kuphela umbutho we-matrix, hayi ubume begrafiki
