45# ishidi lensimbi eligoqiwe elishisayo

Isistimu yokwelapha ukushisa enconyiwe yensimbi engu-45 ecaciswe kuzinga le-GB/T699-1999 ijwayelekile ku-850°C, icisha ku-840°C, futhi ishisa ku-600°C. Ukusebenza okuzuziwe kungamandla esivuno ≥355MPa
Izinga le-GB/T699-1999 libeka ukuthi amandla aqinile wensimbi engu-45 angu-600MPa, amandla okukhiqiza angu-355MPa, izinga lokwelula liyi-16%, futhi ukuncishiswa kwendawo kungu-40%.
Isicelo
Insimbi engu-45 isetshenziswa kabanzi emishinini, uma ingelashwa ukushisa: HB≤229; ukwelashwa ukushisa: normalizing; amandla omthelela: Aku≥39J; amandla aphezulu, ipulasitiki enhle kanye nokuqina, 45# ipuleti lensimbi ngemva kokucisha ngaphandle kokushisa, ubulukhuni bukhulu kune-HRC55 (Kufika ku-HRC62) ifanelekile. Ngemuva kokwelashwa kokushisa nokushisa, ingafinyelela ku-HRC42-46, engakwazi kuphela ukuqinisekisa izakhiwo zayo ezinhle zemishini, kodwa futhi ithole izidingo zokuqina kwendawo. Isetshenziselwa ukwenza ukulungiswa kwezigaba ezincane ezingakwazi ukumelana nemithwalo emikhulu. Izingxenye zekhwalithi nezingxenye ezinkulu ezijwayelekile ezinokucindezeleka okuncane, kanye nezingxenye eziqinile ezingadingi amandla aphezulu, njengamathiphu, okuthunyelwe komhlahlandlela, izandla zewashi nezinye izingxenye.
