Cold drawn steel yog dab tsi?

Cold drawn steel yog cov hlau uas ncab ntawm chav tsev kub nrog lub zog tensile siab tshaj qhov taw tes lub zog ntawm cov hlau qub, thiab tau ncab los tsim cov yas deformation txhawm rau txhawm rau ua kom lub zog taw tes ntawm cov hlau thiab txuag hlau.

1. High precision: Cov txheej txheem tsim khoom siab tshaj plaws ntawm cov khaub thuas rub cov hlau tuaj yeem ua kom muaj qhov ntev thiab qhov zoo, ua rau nws tsim nyog rau kev siv hauv ntau yam kev ua haujlwm, xws li tsheb, aerospace, kev kho mob, hluav taws xob, thiab lwm yam.
2. Zoo plasticity: Cold drawn steel muaj siab plasticity thiab ductility, thiab tuaj yeem ua tau yooj yim rau hauv qhov chaw ntawm ntau yam duab.
3. Corrosion kuj: Cold drawn steel txais kev ua haujlwm txias hauv cov txheej txheem tsim khoom, thiab tau txais kev siab dua thiab kev kho cua sov, uas ua rau nws muaj kev tiv thaiv corrosion siab.
4. Cov khoom siv kho tshuab zoo heev: Cov txheej txheem txias rub tawm steel ua rau nws muaj kev sib koom ua ke ntau dua, ua rau nws zoo heev hauv lub zog thiab toughness.
5. Kev tswj kom raug ntawm cov khoom muaj pes tsawg leeg: Cov txheej txheem txias rub tawm steel tuaj yeem tswj cov khoom muaj pes tsawg leeg, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov haujlwm sib txawv.
6. Kev txuag nqi: Cov nqi tsim khoom ntawm cov hlau txias txias yog qhov tsawg, uas tuaj yeem ua tiav cov txiaj ntsig zoo dua thiab cov txiaj ntsig hauv kev tsim khoom.

Thawj kauj ruam: taub hau kom yooj yim kos duab.
Qhov thib ob theem: annealing.
Qhov thib peb kauj ruam: tua blasting kom tshem tawm cov nplai oxide thiab xeb.
Kauj ruam plaub: phosphating.
Kauj ruam tsib: kos duab. Muaj ntau cov ntaub ntawv uas tsis tuaj yeem kos ib zaug, yog li yuav tsum muaj ntau yam annealing.
Cov kauj ruam kawg yog ncaj nraim thiab xa khoom xa tuaj.
