Ntau hom caij nplooj ntoos hlav steel hlau muaj ntau txoj hauv kev, tab sis lawv txhua tus qhia txog cov yam ntxwv ntawm kev xav tau qee lub zog, siab tawv, thiab kev ua haujlwm zoo coiling.
Kev tsim cov txheej txheem rau ntau lub caij nplooj ntoos hlav steel hlau yog raws li hauv qab no:
(Steel) Hlau pas nrig - Kev kho deg - Hlau kos duab (Cov qauv no tuaj yeem siv rau lub txaj steel hlau)
Lead-quenched caij nplooj ntoos hlav steel hlau: Lead da dej quenching yog ua los ntawm cov hlau rods ntawm qhov yuav tsum tau loj los yog nruab nrab txias- kos specifications, ua raws li los ntawm kev kho deg thiab hlau kos duab.
Galvanized caij nplooj ntoos hlav steel hlau: Kub-dip galvanizing lossis electroplating feem ntau yog ua tiav ntawm cov khoom tiav. Qee qhov kuj yog tsim los ntawm pickling thiab kub -dip galvanizing hlau rods ua raws li cov duab txias rau qhov loj me.
Roj-quenched caij nplooj ntoos hlav steel hlau: Carbon steel los yog hlau alloy yuav siv tau raws li xav tau. Tom qab kev kho deg thiab kos duab txias rau qhov loj tiav, quenching thiab tempering yog ua. Cov txheej txheem no feem ntau yog siv rau lub tsheb ncua kev kawm ntawv thiab lub valve springs, tab sis nws kuj siv tau rau cov springs zoo tib yam.
