Ukuqonda unyango lobushushu lwe-ductile kunye nokuthandabuza amandla kunye nobunzima bemifanekiso ayisiyophupha!

Kwintsimi yokuphosa, intsimbi ye-ductile iye yaba sisixhobo esiguquguqukayo kwizicelo zemizi-mveliso ngenxa yesakhiwo sayo esikhethekileyo. Kunye nonyango lobushushu, njengenyathelo eliphambili ekutyhilekeni kwendlela yokusebenza, kubaluleke kakhulu.

Ke, njani, indlela yokufezekisa ukuhambelana kwamandla, ukuqina, kunye nokunxiba ukunyangwa ngolawulo lwenkqubo? Namhlanje, siya kudibanisa izicelo ezisebenzayo zokushwankathela iinkqubo eziphambili kunye neendawo zokusebenza zonyango lwe-ductile.

Ukudibana kweqondo lokushiyela eliphantsi kufuna ukufudumeza ubushushu ukuya kwi-720-70-760 ℃, ukuyipholisa kwiziko ukuya kwi-500 ℃, emva koko umoya ukuphoxekile kwiziko. Umsebenzi ophambili wale nkqubo kukukhuthaza ukubola kwe-extuctoid carbides, ngaloo ndlela ukufumana isinyithi sentsimbi ye-ferric.

Ngenxa yokusekwa kwe-ferrite matrix, ubunzima bezinto ezibonakalayo zinokuphuculwa kakhulu. Le nkqubo ilungele ngokukhethekileyo kwiimeko apho umxube we-Ferrite, i-Pearlite, iCearlite, kwaye igrafu inyanzelekile ukuba yenzeke kwimithombo yeekheyisi ngenxa yokuqulunqwa kweekhemikhali ngenxa yokuqulunqwa kwemichiza, izinga lokupholisa, kunye nezinye izinto. Ukudibana kweqondo lobushushu eliphantsi Ukuziqhelanisa kunokuphucula ngokufanelekileyo ubunzima belo.

I-02 ye-graftication ye-graftication yobushushu

I-Interrafiting Generation I-Interaction Real kuqala ifuna ukufudumeza ukuphoswa kwe-880-930 ℃, kwaye ke kuyitshintshele kwi-750-760 ℃ kwaye ishiye iziko lokupholisa umoya.

Eyona njongo iphambili yale nkqubo kukuphelisa isakhiwo esimhlophe sokuphosa, ngokufudumeza ngokupheleleyo kwaye sibambe amaqondo obushushu aphezulu, sibongoza isamente kwisakhiwo esimhlophe sokuphosa. Emva kwegrafitic ephezulu yokunyanga impanya, ubulukhuni bokuphosa ukhula, kunye neprimpoty kunye nobunzima kunye nokukhula kwepristrance. Kwangelo xesha, kulula ukusikwa nokuzisika okulandelayo kwaye kulungele izixhobo zentsimbi zentsimbi ezifuna ukuphucula ukusebenza okanye ukuphucula iplastiki kunye nobunzima.

Ukomelela kunye nomlawuli obanzi wokuSebenza

I-02 engaphelelanga i-austerite eqhelekileyo

Iqondo lobushushu lokufudumeza ngenxa yokuziqhelanisa ne-aussistitions eqhelekileyo ilawulwa nge-820-860- Xa ifudumele kolu luhlu lobushushu, ezinye zendlela yematrix iguqula ukuba i-austedite, kwaye emva kokupholisa, isakhiwo esine-Pearlite kunye nenani elincinci lezinto ezenziweyo.

Lo mbutho unokukhulisa izicambuso ezinemilinganiselo elungileyo ebanzi, amandla okulinganisa kunye nobunzima, kwaye ulungele izinto ezakhiweyo ezineemfuno eziphezulu zomsebenzi ophezulu.

Yenza izinto zentsebenzo eziphakamileyo 'ze-hardcore'

I-01 yokucingela kunye nokunyanga umlinganiso (ukucima + ubushushu obuphezulu)

Iiparamitha zenkqubo zokucingela nokunyanga umlinganiso zishushu ngamaqondo obushushu angama-840-880 ℃, ukucima ioyile okanye amanzi okupholisa amaqondo aphezulu, kunye nokucinywa. Ngale nkqubo, isakhiwo seMatrix siguqulwa saba yi-martical evuthayo ngelixa ugcina i-morphology ye-phrite.

Isakhiwo esivuthayo martenate sinepropathi ebanzi yendlela entle, enomdlalo olungileyo phakathi kwamandla kunye nobunzima. Ke ngoko, unyango lokuhamba kunye nokunyanga

I-ShokMathermal ye-Shuench

Inkqubo yenkqubo ye-isothermal ye-isothermal iyakukhumbula ukuya kwi-840-880 ℃, ilandelwe kukuhlambela kwibhafu yetyuwa nge-250-350 ℃. Le nkqubo inokufezekisa i-microstlstal yePropathi yeNtloko zeMilingane yeNgcebiso kwiNgqongolo, idla ngokuba yindibaniselwano ye-Bianete, i-Austedite ye-Ainetedite, kunye negrafu ye-sphere.

I-Isothermal yokungena inokuliphucula kakhulu amandla, ukuqina, nokunxiba ukunganyangeki kwezokulahlekisa, ngakumbi ifanelekile iinxalenye ezineemfuno eziphezulu zokungakhathali kunye nokunxiba njengamakhonkco.

Ukuphuculwa kweNtsebenzo yeNdawo

I-01 indawo yokucima

Ukuhamba rhoqo, ukubuyela rhoqo, idangatye kunye nezinye iindlela zinokusetyenziselwa ukucinywa komhlaba. Ezi ndlela zokwenza izinto ezihamba phambili zenza ubunzima obukhulu uMartierication Martier kumphezulu wokuphoswa kukufudumeza ekuhlaleni kwaye ukhule ngokukhawuleza, ngelixa i-core igcina ubume bayo.

Ukucingela umhlaba kunokuphucula ngokufanelekileyo ubulukhuni, ukunxiba, kunye nokungakhathali kokuphoxeka, kwaye kufanelekile kumacandelo oxinzelelo lwasekhaya olunje ngeejenali ze-cranselift kunye ne-gearties ye-cranks. Ngolwaphulo-mthetho lwasekhaya, ubomi benkonzo bunokwandiswa.

I-02 ethambileyo

Unyango oluthambileyo lwenkqubo yinkqubo yokwenza umaleko odityanisiweyo kumphezulu wenkcaso nge-nitrogen ye-nitrogen carbon cobon.

Le nkqubo inokuphucula kakhulu ubunzima kunye nokunganyangeki komgangatho wokuphosa, kwaye iphucule kakhulu ukunciphisa ukunganyangeki ngaphandle kokunciphisa ubunzima bomhlaba. Ilungele indawo yentsimbi enentsimbi enemilinganiselo yokusebenza ephezulu yomphezulu, njengamalungu omatshini ekufuneka anyamezele ixesha elide.

Amanqaku aphambili omsebenzi wobushushu

I-1. Ukunqongophala kobushushu betyala

Iqondo lokushisa lokuthintela iziko ngokubanzi alidluli kwi-350 ℃. Ukuphoswa ngamandla obukhulu kunye nolwakhiwo oluntsonkothileyo, ubushushu obungena kwiziko kufuneka lube sezantsi (njengezantsi kwe-200 ℃) ukuthintela ukuqhekeka koxinzelelo lweqondo lobushushu olubangelwa lumehluko wobushushu obugqithisileyo. 2. Ukukhetha inqanaba lokufudumeza

Ixabiso lokufudumeza kufuneka lihlengahlengiswe ngokobungakanani kunye nobunzima bokuphosa, ihlala ilawulwa nge-30-120 ℃ / h. Kwiindawo ezinkulu okanye ezintsokothileyo, ireyithi yokufudumeza (njenge-30-50 ℃ / h) kufuneka isetyenziselwe ukuqinisekisa ukufudumeza kunye nokunciphisa umngcipheko wokuphoswa kwengqondo. I-3. Ukumiselwa kwexesha lokufakwa

Ixesha lokufakelwa limiseko ikakhulu ngokusekwe kububutyebi be-Wall, ngokubanzi ukubalwa kwe-1m Ride wonke i-25mm yodonga yonke i-25mm, ukuqinisekisa ukuba ulwakhiwo lweMatrix lunokuguqula ngokupheleleyo ngexesha lokufudumeza kwaye lufezekise isiphumo sonyango lobushushu.

Ukusuka "ekuthambeni" kokungqubana "kokubhomboloza" kokucingela, ukusuka ngokuqinileyo koqiniso kulungelelwaniso, inkqubo nganye kufuneka yenzelwe ngokusekelwe ekuqulunqweni kwempahla, indawo kunye neemeko zenkonzo. Kucetyiswa ukuba uvimba weenkcukacha "weNkqubo yokuSebenza" kunye nokuSebenza ngokuSebenza ngokuSebenzayo ngohlalutyo lwe-itaitrographic (enjengokuvavanywa kwe-Peinlite), i-injini ye-Gensli / etyhidiweyo "ukuphucula ukhuphiswano lwemveliso.
