Vim yog qhov brittleness loj ntawm lub casting nws tus kheej, thiab qhov cuam tshuam ntawm cov txheej txheem casting thiab kev kho cua sov, muaj ntau qhov tsis zoo hauv cov khoom tiav. Hauv kev siv ua haujlwm, cov khau khiav ntub dej casting feem ntau tawg. Txij li thaum lub log qhia yog ib qho qauv tseem ceeb ntawm kev casting, thaum cov kab nrib pleb tshwm sim Los yog qhov tshwm sim tawg yuav tsum tau muab pov tseg tag nrho. Tsis tas li ntawd, lub log qhia casting yuav tsum tau nqis peev rau hauv pwm, cov khoom siv kho cua sov, thiab cov zoo li, thiab tus nqi tsim khoom siab.
Cov khau khiav hauv av uas tau ua tiav hauv qab no suav nrog cov khau khiav peb-hniav, lub phaj npog kawg, lub phaj nkhaus sab laug, tav pem hauv ntej, tav nraub qaum, phaj ntsug nruab nrab, phaj nkhaus sab xis, thiab phaj nkhaus sab laug thiab phaj nkhaus sab xis yog welded raws li. Ntawm sab laug thiab sab xis ntawm sab saud ntawm cov khau khiav peb-hniav, cov phaj npog kawg yog welded rau ob sab nraud ntawm cov khau khiav peb-hniav, cov phaj nkhaus sab laug thiab sab xis, thiab phaj ntsug nruab nrab yog welded rau nruab nrab sab saud ntawm cov khau khiav peb-hniav. Cov tav txhawb pem hauv ntej thiab cov tav txhawb nram qab yog welded ntawm ob sab thiab cov khau khiav peb-hniav. Cov tav txhawb pem hauv ntej thiab nraub qaum ntawm ob sab raug kaw rau ntawm cov qhov chaw sab hauv ntawm cov phaj nkhaus sab laug thiab sab xis. Lub phaj nkhaus sab xis thiab phaj ntsug nruab nrab yog downward.
Lub khau khiav peb-hniav tuaj yeem raug quenched thiab tempered kom txhim kho nws lub zog thiab toughness, thiab nws tsis yooj yim rau khoov thiab tawg. Lub phaj sab laug-khoov thiab lub phaj sab xis-khoov yog tau los ntawm kev khoov thiab machining ntawm cov phaj siab-muaj zog, nrog lub zog siab, kev ua haujlwm vuam zoo, thiab thaj chaw sib cuag loj nrog hauv av. , Ua kom cov khau khiav ntub dej lo rau hauv av thiab txhim kho lub peev xwm hla ntawm lub bulldozer; lub phaj ntsug nruab nrab yog lub phaj siab-muaj zog nrog lub zog siab, kev ua haujlwm vuam zoo, kev tiv thaiv hnav, thiab txhim kho lub zog tag nrho ntawm cov khau khiav ntub dej. Lub phaj ntsug nruab nrab siab dua li lub phaj nkhaus sab laug thiab lub phaj nkhaus sab xis, thiab qhov siab dua tuaj yeem ua rau muaj peev xwm tuav ntawm cov khau khiav ntub dej hauv av thiab txhim kho lub peev xwm hla ntawm lub bulldozer.
