Cov ntaub ntawv hlau uas feem ntau siv rau hauv cov khoom siv kho vajtse uas peb feem ntau siv suav nrog cov hlau tsis xeb, tooj liab, txhuas, zinc alloy, magnesium alloy, hlau, hlau, thiab lwm yam.
Raws li cov txheej txheem ua ntau yam, cov khoom siv kho vajtse feem ntau muab faib ua cov txheej txheem txias thiab cov txheej txheem kub, thiab ntau hom kev tsim hlau kuj txawv. Cov ntaub ntawv ua txias xws li cov hlau ntawv feem ntau yog tsim los ntawm kev tuag txias stamping, khoov, kos duab tob thiab lwm yam txheej txheem. Cov khoom ua haujlwm kub, xws li cov khoom casting, feem ntau yog ua los ntawm kev yaj cov khoom siv kho vajtse raw rau hauv kua thiab casting nrog pwm.
Feem ntau ntseeg tias txhua yam hlau uas muaj tuab sib npaug hu ua hlau. Cov hlau uas siv ntau suav nrog hlau tsis xeb, hlau galvanized, hlau tinplate, tooj liab, txhuas, hlau, thiab lwm yam.
❶ lub hauv paus ntsiab lus ntawm cov khoom tuab sib xws
Cov hlau ntawv yog cov khoom siv uas muaj cov tuab sib xws, uas yuav tsum tau them sai sai rau hauv kev tsim qauv, tshwj xeeb tshaj yog qhov twg muaj ntau qhov khoov, nws yooj yim ua rau tsis sib xws.
❷ lub hauv paus ntsiab lus ntawm kev yooj yim flattening
Cov khoom siv hlau yog ua los ntawm cov ntawv. Ua ntej ua tiav, cov khoom siv raw yog tiaj tus. Yog li ntawd, thaum tsim cov khoom siv hlau, txhua qhov khoov thiab cov dav hlau inclined yuav tsum muaj peev xwm nthuav tawm ntawm tib lub dav hlau yam tsis muaj kev cuam tshuam. Piv txwv li, kev tsim cov khoom siv hlau uas pom hauv Daim Duab 1-1 tsis tsim nyog vim tias lawv cuam tshuam nrog ib leeg tom qab nthuav tawm.
❸ lub hauv paus ntsiab lus ntawm kev xaiv cov tuab ntawm cov hlau ntawv kom raug
Qhov tuab ntawm cov hlau ntawv sib txawv ntawm 0.03 txog 4.00 hli, tab sis qhov tuab dua, qhov nyuaj dua rau kev ua tiav, qhov xav tau cov khoom siv ua tiav ntau dua, thiab qhov tsis xws luag nce ntxiv. Qhov tuab yuav tsum xaiv raws li qhov ua haujlwm tiag tiag ntawm cov khoom. Ntawm lub hauv paus ntawm kev ua tau raws li lub zog thiab kev ua haujlwm, qhov nyias dua qhov zoo dua. Rau feem ntau cov khoom, qhov tuab ntawm cov hlau ntawv yuav tsum tswj hwm qis dua 1.00 hli.
❹ ua raws li lub hauv paus ntsiab lus ntawm kev siv tshuab ua tiav
Cov khoom siv hlau yuav tsum ua raws li cov txheej txheem ua khoom thiab yooj yim rau kev tsim khoom. Cov khoom uas tsis ua raws li cov txheej txheem ua khoom yuav tsis tuaj yeem tsim tau, uas yog, kev tsim qauv tsis tsim nyog.
