Kev kho cua sov ib txwm siv rau tuag-casting pwm muaj quenching thiab tempering, ua raws li cov txheej txheem kho deg. Vim tias muaj ntau yam khoom siv tuaj yeem siv rau kev tuag- casting pwm, tib cov txheej txheem kho thiab txheej txheem tuaj yeem tsim cov txiaj ntsig sib txawv ntawm cov khoom sib txawv. Schoff tau npaj cov txheej txheem ua ntej ua ntej ua ntej uas hais txog ob qho tib si pwm substrate thiab cov txheej txheem kho saum npoo. Ua raws li cov txheej txheem ib txwm muaj, cov cuab yeej no tsim cov txheej txheem tsim nyog rau cov khoom pwm sib txawv, yog li txhim kho pwm kev ua tau zoo thiab txuas ntxiv lub neej pwm. Lwm cov kev taw qhia rau kev txhim kho kev kho cua sov thev naus laus zis yog los ua ke cov txheej txheem kev kho cua sov ib txwm siv nrog cov txheej txheem kho saum npoo av kom txuas ntxiv kev pab cuam lub neej ntawm tuag-casting pwm. Piv txwv li, kev sib xyaw carbonitriding, tshuaj kho cua sov txoj kev, nrog cov pa quenching thiab tempering txheej txheem kom ua tiav NQN (carbonitriding-quenching-carbonitriding composite ntxiv dag zog rau) tsis tsuas yog ua rau saum npoo hardness, tab sis kuj ua rau cov txheej txheem hardened zoo, optimizes hardness gradients thiab tempering stability. Qhov no tso cai rau tuag-casting pwm kom ua tiav cov haujlwm tseem ceeb thaum txhim kho qhov zoo thiab kev ua haujlwm tag nrho.
Tuag- casting pwm yog ib pawg loj ntawm pwm. Nrog rau txoj kev loj hlob sai ntawm kuv lub teb chaws kev lag luam tsheb thiab maus taus, tuag- kev lag luam casting tau nkag mus rau lub sijhawm tshiab ntawm kev txhim kho, ib txhij muab cov kev xav tau siab dua ntawm cov khoom siv kho tshuab dav dav thiab lub neej ntawm kev tuag- casting pwm. Luo Baihui, Tus Tuav Ntaub Ntawv -General ntawm International Pwm Association, ntseeg... Kom ua tau raws li qhov xav tau ntawm kev ua tau zoo dua qub, kev cia siab rau cov khoom pwm tshiab tsuas yog tsis txaus. Ntau yam kev siv thev naus laus zis yuav tsum tau siv rau kev kho deg tuag- casting pwm kom ua tiav qhov yuav tsum tau ua haujlwm siab, siab precision, thiab lub neej ua haujlwm ntev. Ntawm ntau yam pwm, tuag- casting pwm ua haujlwm raws li qhov xav tau tshaj plaws. Kev kub siab casting suav nrog sau cov pwm kab noj hniav nrog cov hlau molten nyob rau hauv kev kub siab thiab kev kub ceev los tsim cov pwm zoo. Thaum lub sijhawm ua haujlwm, cov pwm rov qab los rau hauv kev sib cuag nrog cov hlau incandescent, yog li yuav tsum tau ua haujlwm siab rau thermal qaug zog, thermal conductivity, hnav tsis kam, corrosion kuj, cuam tshuam toughness, liab hardness, thiab zoo demolding zog. Yog li ntawd, cov txheej txheem kho saum npoo rau tuag-casting pwm muaj qhov xav tau siab.
