Izinto ezingu-9 ze-cr2mo zensimbi evamile ye-Cr2 ebandayo isembonini esetshenziswa kakhulu ekwenzeni amakhaza agoqwe nge-roller ye-cold die kanye ne-punch njll kodwa abaningi bathi abazi mayelana nendlela yokwelapha ukushisa engu-9 cr2mo, ngakho-ke lapha ikakhulukazi. ukukhuluma mayelana ne-9 cr2mo indlela yokwelapha ukushisa, ngethemba ukuthi izoba yi-spheroidizing annealing: 1 790 ~ 810 ukufudumeza, isothermal, 650 ~ 670, 500 kusuka ekupholiseni komoya; 2 ukucisha: izinga lokushisa lokushisa =880~900, ukupholisa okucisha: ngokusho kwezinhlobonhlobo ezahlukene kanye nezidingo ezahlukene, i-cooling medium efana ne-water PAG quenching fluid oil ingasetshenziswa.
Qaphela: Ama-forgings ayinsimbi ejwayelekile ye-Cr2.
3 Izinga lokushisa lephuzu elibalulekile (inani elilinganiselwe):Ac1 =740 C Ar1 =700 C Accm :850 C 4 Izicaciso ezijwayelekile zokuthambisa ngokucindezelwa okubandayo kungenalutho820 10) C 3 ~4h, ngesilinganiso sokupholisa esingu-.15 C/h, isithando somlilo siphola kancane sibe ku-650 C, 5 okucindezelwe okubandayo kungenalutho ukusuka kuhhavini ukupholisa kuya ekucacisweni kokuthambisa okuphothiwe820 10) C 3 ~4h, (720 10) C 6 ~8h, bese kuthi isithando somlilo siphole kancane sibe ngu-600 C,Ukucaciswa kokujwayelekile: izinga lokushisa elijwayelekile 900 ~920 C, ubulukhuni 302-388HBW 7 Iqoqo le-isothermal spheroidizing0 Annealing ~79 810 C 2 ~3h, ukupholisa isithando somlilo, 7O0-720 C 3 ~4h, ubulukhuni 217HBW, I-Pearlitic tissue grade 2-5,Isicaciso sokucisha kanye nokushisa okungu-8 kwe-mesh carbide grade 2 1. Ukushisa okucisha 830-850 C, ukuqina 62-65 HRC, tempering lokushisa 130-150 C, ubulukhuni 62-65 HRC 2. Ukushisa kokucisha 840-860 C, ubulukhuni 61-63 HRC, tempering lokushisa 150-170 C, ubulukhuni 60-62HRC.
