Iimathiriyeli ezi-9 ze-cr2mo zentsimbi eqhelekileyo ye-Cr2 ebandayo ikwimizi-mveliso esetyenziselwa ukwenziwa kwezinto ezibandayo eziqengqelekayo kunye ne-roller yokufa ebandayo kunye ne-punch njl. Ukuthetha nge-9 cr2mo yonyango lwendlela yobushushu, ithemba lokuba yi-spheroidizing annealing: 1 790 ~ 810 ukufudumeza, isothermal, 650 ~ I-670, i-500 ukusuka ekupholiseni komoya; ukucima i-2: ubushushu bokufudumala = 880 ~ 900, ukucima ukupholisa: ngokweendlela ezahlukeneyo kunye neemfuno ezahlukeneyo, indawo yokupholisa njengamanzi e-PAG yokucima ioli yolwelo ingasetyenziswa.
Qaphela: I-forgings yintsimbi eqhelekileyo ye-Cr2.

3 Iqondo lobushushu elibalulekileyo (ixabiso eliqikelelweyo):Ac1 =740 C Ar1 =700 C Accm :850 C 4 Iimpawu zokuthambisa eziqhelekileyo zokungacwangciswanga okubandayo820 10) C 3 ~ 4h, kunye nesantya sokupholisa se.15 C / h, kunye neziko liphola ngokucothayo ukuya ku-650 C, i-5 ebandayo ecinezelweyo ingenanto ukusuka kwi-oven yokupholisa ukuya kwi-spindle-spindled softening specifications.820 10) C 3 ~ 4h, (720 10) C 6 ~ 8h, emva koko kunye neziko liphola ngokucothayo ukuya ku-600 C,Inkcazo yokuqhelanisa: ubushushu obuqhelekileyo 900 ~ 920 C, ubulukhuni 302-388HBW 7 Ibhetshi isothermal spheroidizing0aling ~79 810 C 2 ~3h, ukupholisa iziko, 7O0-720 C 3 ~ 4h, ubulukhuni 217HBW, iPearlitic tissue grade 2-5,Inkcazo yokucima kunye nokutshisa i-8 forgings ye-mesh carbide grade 2 1. Ukucima ubushushu 830-850 C, ubunzima 62-65 HRC, ukushisa kwe-130 150 C, ubunzima 62-65 HRC 2. Ukucima ubushushu 840-860 C, ubulukhuni 61-63 HRC, iqondo lokushisa 150-170 C, ubulukhuni 60-62HRC.
