Kub Rolling yog dab tsi?

Kub dov yog txheej txheem hlau siv los tsim thiab deform hlau ntawm qhov kub thiab txias. Nws yog ib qho ntawm cov txheej txheem siv hlau ntau tshaj plaws thiab dav siv los ua cov khoom siv hlau ntau yam nrog cov duab sib txawv thiab qhov ntev. Nyob rau hauv kub dov, cov hlau yog dhau los ntawm ib tug series ntawm rollers thaum nws yog rhuab mus rau ib tug high kub, feem ntau saum nws recrystallization kub. Cov hlau tseem ceeb uas raug kub dov muaj xws li steel, aluminium, thiab lwm yam alloys.

Cov txheej txheem kub dov muaj cov kauj ruam hauv qab no:

1. Cua sov: Cov hlau yog rhuab nyob rau hauv lub cub tawg mus rau qhov kub siab tshaj nws recrystallization kub. Qhov kub no txawv nyob ntawm seb hom hlau thiab nws cov alloying ntsiab. Cov cua sov yog qhov tseem ceeb los ua kom cov hlau ua kom zoo dua qub thiab txo nws lub zog, ua rau nws yooj yim dua thaum dov.

2. Rolling: Cov hlau rhuab yog ces dhau los ntawm ib tug series ntawm rollers nyob rau hauv ib tug dov zeb. Lub tshuab dov tuaj yeem muaj ob peb yob txheej txheej ib ntus, txhua tus ua haujlwm tshwj xeeb hauv cov txheej txheem deformation. Cov chais yaig siv lub zog ntawm cov hlau, ua rau nws deform thiab hloov nws cov duab thaum nws hla lub zeb.

3. Txo cov tuab: Raws li cov hlau hla dhau ntawm cov chais, nws dhau los ntawm cov yas deformation, ua rau txo qis hauv thickness thiab nce qhov ntev thiab dav. Lub degree ntawm thickness txo yog nyob ntawm qhov pib thickness ntawm cov hlau thiab qhov xav tau zaum kawg thickness.

4. Shaping: Cov rollers nyob rau hauv lub dov zeb tuaj yeem muaj ntau yam profiles kom ua tiav cov duab tshwj xeeb hauv cov khoom kawg. Cov hlau tuaj yeem dov rau hauvnplooj ntawv, strips,daim hlau, tuav, thiab lwm yam qauv duab.

5. Kev ua kom txias thiab ua haujlwm ntxiv: Tom qab kub dov, cov hlau feem ntau yog txias rau hauv kev tswj kom ruaj khov nws cov microstructure. Raws li qhov kawg ntawm cov khoom yuav tsum tau ua, cov txheej txheem ua haujlwm ntxiv xws li txiav, khoov, thiab kho qhov chaw yuav raug ua.

Kub dov yog siv dav hauv kev tsim khoom ntawm ntau yam khoom siv hlau, nrog rau cov ntawv hlau, cov nplooj ntawv, tuav, ntsia hlau, thiab cov khoom seem. Nws muaj ntau yam zoo, xws li kev txhim kho cov khoom siv, zoo dua qhov tiav, thiab cov nqi ntau lawm sai dua piv rau lwm cov txheej txheem hlau xws li txias dov. Txawm li cas los xij, nws yuav tsum muaj lub zog loj thiab muaj kev txwv hauv kev tsim cov duab nyuaj nrog kev ua siab ntev, uas yog qhov zoo dua los ntawm lwm txoj kev tsim xws li forging lossis casting.
