Ua ntej tshaj tawm covtooj liabtxheej txheem thiab txheej txheem, cov txheej txheem hlau yog dab tsi?
1. Hlau solidification thiab forming yog customarily hu ua casting.Casting yog txheej txheem uas molten hlau yog poured, txhaj los yog nqus tau rau hauv pwm kab noj hniav, thiab tom qab nws solidifies, ib tug casting nrog ib tug tej yam zoo thiab kev ua tau zoo.
2. Kev tsim cov yas hlau yog ib txoj hauv kev uas siv cov yas deformation muaj peev xwm ntawm cov ntaub ntawv hlau los tsim cov yas deformation ntawm cov ntaub ntawv hlau nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam kom tau txais qhov chaw lossis qhov khoob nrog qee yam zoo li, qhov loj thiab cov khoom siv kho tshuab.Nws cov txheej txheem feem ntau tuaj yeem muab faib ua dawb forging, tuag forging, ntawv hlau stamping, extrusion, nias, thiab lwm yam.Qhov zoo ntawm forging yog feem ntau ntsuas los ntawm plasticity thiab deformation kuj ntawm cov hlau.Yog hais tias lub plasticity siab thiab deformation kuj zoo, lub forgeability yog zoo;txwv tsis pub, lub forgeability yog pluag.
3. Hlau vuam txheej txheem.Vuam yog ib txoj kev tsim uas cov ntaub ntawv hlau ua tiav atomic bonding los ntawm cua sov los yog nias los yog ob qho tib si, nrog los yog tsis muaj cov ntaub ntawv muab tub lim.Cov kev faib tawm ib txwm yog fusion vuam, siab vuam, thiab brazing.
Dab tsi yog cov txheej txheem kev tsim cov pas nrig tooj liab?Muaj ntau ntau txoj kev ua tooj liab, suav nrog extrusion, dov, nruam casting, ncab, thiab lwm yam.
Txoj kev ua tus pas nrig tooj liab?Muaj peb hom tooj liab qws txheej txheem, raws li hauv qab no
1. Nias-(rolling)-stretching-(annealing)-cov khoom tiav.
2. Nruam casting (sab sauv, kab rov tav lossis log hom, crawler hom, dipping)-(rolling)-stretching-(annealing)-cov khoom tiav
3. Nruam extrusion-stretching-(annealing)-cov khoom tiav-ua tiav.
