Umphumela Wokushisa Kwe-Annealing Ku-Chilled Low Chromium Molybdenum Ductile Iron Roll

Ethintwe inqubo yokusakaza, iroli yensimbi epholile ye-chromium molybdenum ductile ine-cassion enkulu yokuphonsa esimweni se-cast, ngakho-ke ukwelashwa kokunciphiswa kwengcindezi kuyadingeka. Ukuzijwayeza kukhombisile ukuthi ukukhululeka kokuncishiswa kokungezwa kokushisa akuthinti kuphela izinga lokususa ukukhululeka kwengcindezi, kepha futhi kuthinta ukwakheka nokusebenza kweroli.

Usebenzisa isithando somlilo samandla wamandla ukuzwa insimbi encibilikisiwe, inqubo ethululela phansi, ubukhulu bendawo yokusebenza esebenza ngama-288mm, futhi ukwakheka kukhonjiswa kuThebula 1. Sebenzisa i-lathe ukusika u-20mm ubukhulu nobubanzi obungu-40mm (ubukhulu be-radial ) indandatho kusuka kungqimba olubandisiwe olubandisiwe. Iringi yasikwa yaba amasampula amaningana, akhonjiswa ngeminwe kwashiswa ukushisa ngamazinga okushisa ahlukene, kwase kubhekwa isakhiwo sobulukhuni nobulukhuni.

 Umdwebo 1 ukhombisa ukwakheka kwe-metallographic engaphandle kweringi enqunyiwe (eduze kohlobo olubandayo) nangaphakathi kwendandatho esikiwe (eduze komongo weroli). Umdwebo 1a no-Figure 1b bakhombisa ukuthi isakhiwo salo msongo yi-pearlite, i-ledeburite ne-carbide. Inani lama-carbides angaphandle kwendandatho e-tangent lingaphezulu, futhi inani le-pearlite lincane, futhi inani le-carbides ngaphakathi kwendandatho e-tangent lincane, futhi inani le-pearlite lingaphezulu. . Ukuhlolwa kukhombisa ukuthi noma ngabe ukushisa kokuncishiswa kufinyelela kuma-600 ° C futhi isikhathi sokubamba kungamahora ama-4, ukwakheka komqulu akukabi noshintsho olusobala, njengoba kukhonjisiwe ku-Figure 1c naku-Figure 1d.

(c) Uhlangothi olungaphandle ngemuva kokuphathwa kokushisa okungu-600 ℃ × 4h (d) Uhlangothi olungaphakathi ngemuva kokwelapha okungu-600 ℃ × 4h

Umdwebo 1 Isakhiwo seRoll metallographic

Umdwebo 2 ukhombisa ubulukhuni ezindaweni ezahlukahlukene zendandatho enqunyiwe yesendlalelo sokusebenza ku-as-cast state nangemva kokwelashwa okuhlukile kokushisa. Lesi sibalo sikhombisa ukuthi ubulukhuni bomqulu buyehla kancane kancane busuka ngaphandle buye ngaphakathi kwendandatho yokusika. Ngemuva kokwelashwa kokushisa, ubulukhuni bomqulu buyancipha, futhi ukwehla kobulukhuni kuyanda ngokwanda kwezinga lokushisa lokwelashwa kokushisa. Lapho ukushisa kokwelashwa kokushisa kufinyelela ku-600 ° C, ubulukhuni buyancipha kakhulu. Ngokuya ngezidingo zamakhasimende ngobulukhuni bamaroli, sikhetha ukushisa okunezelayo okungu-400 ℃ ekukhiqizeni.

Ingxoxo

Ukwehliswa kobunzima be-roll ngemuva kokwelashwa kokushisa kubangelwa izinto ezintathu. Okunye ukuthi isakhiwo se-metallographic siyashintsha ngesikhathi sokwelapha ukushisa, njengokuwohloka kwama-carbides. Ngokuya nge-Figure 1, noma ngabe izinga lokushisa lokushisa lifinyelela ku-600 ° C, isakhiwo salo roll asinalo ushintsho olukhulu. Lo mphumela uhambisana nomdwebo wesigaba se-ferroalloy [1]. Kungabonakala ukuthi ukwehla kobunzima be-roll akubangelwa izinguquko esakhiweni se-metallographic. Okwesibili ukuthi izakhi zokuxuba zisakazeka ngendlela efanayo futhi nezinga lokuphakanyiswa kwehle kakhulu ngesikhathi senqubo yokwelashwa kokushisa, okungukuthi, okubangelwa izinguquko ku-microstructure. Ukuze kutholakale umphumela walesi sici, ukuhlolwa kukalwe ubukhulu be-carbide ne-pearlite ngemuva kwezindlela ezehlukene zokwelashwa (bheka Umfanekiso 3). Imiphumela yokukala ikhombisa ukuthi ubukhulu be-pearlite nama-carbide bancishiswa baba ngamazinga ahlukahlukene ngemuva kokwelashwa kokushisa. Le nto kumele iholele ekwehliseni ubulukhuni be-macroscopic roll. Okwesithathu ukwehliswa kobunzima be-macroscopic roll ngokukhululeka kwengcindezi yokusakaza.

Isiphetho

Ngemuva kokuthi iroli yensimbi ye-chromium molybdenum ductile efriziwe epholile ifakiwe futhi ukushiswa kuphathwa ngaphansi kuka-600 ° C, isakhiwo se-metallographic asishintshi kakhulu, kepha ubulukhuni be-macroscopic buyancipha. Lapho ithempelesha yokwelashwa kokushisa ingaphansi kuka-450 ° C, ubunzima obubambisanayo buyancipha kancane, futhi lapho izinga lokushisa lokwelashwa kokushisa liphakeme kuno-600 ° C, ubulukhuni buyancipha ngaphezulu. Isizathu sokwehla kobulukhuni be-macroscopic ukwehla kobunzima obuncane kanye nokuqedwa kwengcindezi yokusakaza.
