Ukucishwa kwensimbi ukushisa insimbi kwizinga lokushisa elibucayi ac3a (i-sub-eutectic steel) noma i-ac1 (ngaphezulu-lensimbi) ngaphezulu kwezinga lokushisa, bamba yonke isikhathi, bese kuthi ngokushesha Kunamazinga okupholisa abucayi amanani apholile wokupholisa okusheshayo kuma-MS aphansi (noma ama-MS eduze kwenqubo yokwelashwa yokushisa ye-Martensite A (noma Baini). Imvamisa futhi i-Aluminium Alloys, ama-alloys ethuni, ama-alloys we-titanium, ingilazi evuthayo nezinye izinto zokwakha isixazululo esiqinile inqubo yokwelashwa esiqinile ebizwa ngokuthi ukujula ".
Inhloso yokucima:
(1) Thuthukisa izakhiwo zemishini zensimbi zibe yizinto ezibonakalayo noma izingxenye.
(2) Thuthukisa izakhiwo ezibonakalayo noma izakhiwo zamakhemikhali zensimbi ethile ekhethekile
Ukuqeda Izindlela: Kakhulu ukujuluka okufuywe okukodwa, umlilo owuketshezi onamanzi aphindwe kabili, ukujuluka okuhlangene, okususiwe okususiwe, ukujuluka kwasendaweni nokunye.
Ukufutheka kuyinsimbi ecinyiwe kuzinto ezibonakalayo noma ingxenye eshiswe emazingeni okushisa athile, ngemuva kokubamba isikhathi esithile, kupholile ngendlela ethile yenqubo yokushisa, ukufudumala kuwukusebenza ngokushesha okukhulu ngemuva kokushiswa kokushisa yenqubo yokugcina, futhi ngenxa yalokho inqubo ehlanganyelwe yokuqeda nokugunda ibizwa ngokuthi ukwelashwa kokugcina.
Indima yokuguga yile:
.
(2) Susa izingcindezi zangaphakathi ukuze kuthuthukiswe ukusebenza kokwenza umsebenzi wokusebenza futhi uzinze i-geometry yendawo yokusebenza.
(3) Lungisa izakhiwo zemishini zensimbi ukuze uhlangabezane nezidingo zokusebenzisa.
Izidingo Zokulangazelela: Ukusetshenziswa okuhlukile kwe-workpiepe kufanele kufuzeke emazingeni okushisa ahlukene ukuze ahlangabezane nezidingo ezisetshenziswayo. . ngcono. (2) Intwasahlobo ngo-350 ~ 500 ℃ ngaphansi kokushisa okushisa okuphakathi, kungathola ukuqina okuphezulu kanye nobunzima obudingekayo. .
Ukuguqula uhlobo lokwelashwa kokushisa ukuthuthukisa ubulukhuni bensimbi, izingxenye zensimbi zifudunyezwa ekushiseni kwe-AC3 ngenhla 30 ~ 50 ℃, ngemuva kokubamba isikhathi ngaphandle komoya. Isici esiyinhloko ukuthi izinga lokupholisa lishesha ukwedlula ukubuya futhi liphansi kunokuqedwa okusheshayo, okujwayelekile kungaba nokupholisa okusheshayo ekuhlaziseni okusanhlamvu kwensimbi, okuphelele kungathola amandla amancane, futhi kungathuthukisa kakhulu i-capriciouscess encane (inani le-AKV ), yehlisa ukuthambekela kokuqhekeka kwengxenye, elinye ipuleti lensimbi elishisayo elishisayo, lokhu kukhokhiswa kwensimbi ephansi kanye nokukhokhiswa okwejwayelekile, imishini ephelele Izakhiwo zezinto ezibonakalayo zingadlalwa ukuze zithuthukise, kepha futhi zithuthukisa ukusebenza kokusika.
Ukuncishiswa yinsimbi kufudunyezwa kancane kancane kumazinga okushisa athile, kugcinwe isikhathi esanele isikhathi, bese kuthi ngenani elifanelekile lendawo ebandayo yenqubo yokushisa ukushisa kwensimbi. Ukuvuselela ukwelashwa okushisa kuhlukaniswe ku-Anveang anvealing, anveling anvealing and dessete inveling and tures expression. Izakhiwo zemishini zezinto zokwenziwa ezingezwe zisetshenziswe tensaile test to Kinze, nazo zingatholwa ukuhlolwa kanzima. Izinto eziningi zensimbi zihlinzekwa ngesimo esiphindisiwe sokushisa, ukuhlolwa kwensimbi yensimbi kungasetshenziswa ubuqili be-Locken Hardeness, ukuhlolwa kwe-HRB, ngamapuleti ensimbi omncane, imichilo yensimbi emincane, ungasebenzisa umhloli we-hardness wensimbi , Izinto zokwakha HRT HARDNESS.
Inhloso yokucimanisa nokukhulisa: 1 ukuthuthukisa izimpahla ukuze uqede okuqinile ekukhupheleni, ekwenzeni, ukuqubuka kanye nokuxineka okubangelwa izinhlobonhlobo zenhlangano, kanye nokuxineka okuseleyo, ukuvimbela ukonakala kwe-workpie, ukuqhekeka. 2 ukuthambisa umsebenzi wokwenza umsebenzi ukuze wenze ukusika. 3 Ukuze ucwenge okusanhlamvu, ukuthuthukisa inhlangano ukuze kuthuthukiswe izakhiwo zemishini zomsebenzi. 4 Okwelashwa kokugcina kokushisa (ukujuluka, ukufutheka) ukwenza umsebenzi omuhle wezindinganiso zenhlangano.
Izinqubo ezisetshenziswayo ezisetshenziswayo zisetshenziswa:
(1) ukunxusa ngokuphelele. Isetshenziselwa ukucwilisa i-carbon yensimbi ephakathi nendawo ngokuphonsa, okusole kanye nokufudumala ngemuva kokuvela kwezindawo ezingezinhle zemishini yezicubu ezibucayi ezibucayi.
(2) ukuvezwa kwe-spheroidal. Isetshenziselwa ukunciphisa ubulukhuni obuphezulu bensimbi yensimbi nokuthela ngensimbi ngemuva kokuphendula.
(3) anveling anveling. Isetshenziselwa iJiangdu i-nickel ethile, i-chromium yokuqukethwe ye-angle yensimbi yensimbi ebungu bulukhuni obuphezulu bensimbi.
(4) Ukuphindaphindeka kabusha kwenziwa kabusha. Kusetshenziselwa i-trolley metal wire, ishidi kumdwebo obandayo, inqubo ebandayo ebandayo ye-harmoning phenomenon (lukhuni luyanda, ipulasitiki iyancipha)
(5) ukuvezwa kwe-graphitization. Kusetshenziselwe ukwenza i-Iron ye-Caspot equkethe inani elikhulu lomzimba olithwelwe emzimbeni wensimbi e-mallgeble ap ngensimbi enhle.
(6) Ukuphikisana nokuvezwa. Kusetshenziselwe ukwenza ukwakheka kwamakhemikhali kwe-alloy castings umfaniswano, ukuthuthukisa ukusebenza kwawo.
(7) Ukusiza Ukuzilibazisa. Isetshenziselwe ukuqeda ingcindezi yangaphakathi yokukhokhiswa kwensimbi kanye nama-weldention.
