Raws li kev lag luam kev lag luam hauv kev siv tshuab hnyav, ib qho dawb forging tsim siv hydraulic presses nrog lub peev xwm forging ntau tshaj 1000 tons tuaj yeem raug xa mus rau qhov loj forging. Raws li lub peev xwm forging ntawm hydraulic presses dawb forging, qhov no kwv yees sib haum rau ncej forgings hnyav tshaj 5 tons thiab disc forgings hnyav tshaj 2 tons.
Cov yam ntxwv tseem ceeb thiab tseem ceeb ntawm cov forgings loj yog lawv qhov loj me thiab hnyav hnyav. Piv txwv li, qhov loj ntawm 600MW chav turbine generator rotor forging yog φ1280mm × 16310mm, hnyav 111.5 tons. Qhov loj ntawm 2200-2400MW chav turbine generator rotor forging yog φ1808mm × 16880mm, hnyav 247 tons.
Vim lawv qhov loj thiab qhov hnyav, cov forgings loj yuav tsum ncaj qha forged los ntawm cov hlau loj loj. Nws paub zoo tias cov hlau loj loj feem ntau muaj teeb meem loj xws li kev sib cais, porosity, shrinkage, non-metallic inclusions, thiab ntau hom kev tsis sib xws. Lawv kuj zoo li muaj cov ntsiab lus roj ntau dua, thiab cov teeb meem no nyuaj rau tshem tawm thaum cov txheej txheem forging tom ntej. Raws li qhov tshwm sim, cov tshuaj lom neeg muaj pes tsawg leeg tseem ceeb tsis sib xws, muaj kev sib txawv ntawm cov qauv tsis xws luag, thiab qib siab ntawm cov pa phem feem ntau tshwm sim hauv cov forgings loj. Qhov no ua rau cov txheej txheem kev kho cua sov kom loj forgings complex, siv sij hawm, thiab kim. Yog li ntawd, ua tib zoo saib xyuas yuav tsum tau them thaum lub sij hawm kho cua sov.
Tsis tas li ntawd, vim lawv qhov loj me thiab qhov hnyav, cov forgings loj muaj peev xwm ua kom muaj cua sov ntau dua, uas ua rau nws tsis tuaj yeem ua tiav cov cua sov thiab cua txias thaum lub sij hawm kho cua sov. Yog li ntawd, rau cov forgings loj uas xav tau kev hloov pauv tseem ceeb hauv cov qauv sab hauv los ntawm tempering lossis quenching kom tau raws li qhov kev ua tau zoo thiab cov kev xav tau zoo, cov khoom siv ruaj khov supercooled austenite thiab siab hardenability steels yuav tsum tau siv. Piv txwv xws li Ni-Cr-Mo, Ni-Mo-V, thiab Ni-Cr-Mo-V series steels. Txawm li cas los xij, cov hlau uas muaj kev ruaj ntseg siab ntawm supercooled austenite yog qhov ua rau cov khoom qub txeeg qub teg, uas ua rau cov ntxhib thiab tsis sib xws hauv cov hlau alloy forgings. Txhawm rau daws qhov teeb meem no, kev kho cua sov tshwj xeeb thiab nyuaj feem ntau yuav tsum tau ua.
