Qhov sib txawv ntawm cov hlau kub dov thiab cov hlau txias dov

Kev txhais ntawm cov hlau kub dov

Cov hlau kub dov dav tsawg dua lossis sib npaug rau 600 hli, tuab ntawm 0.35-200 hli hlau phaj thiab tuab ntawm 1.2-25 hli hlau strip.

 

Kev Taw Qhia Txog Kev Lag Luam Kub Rolled Strip thiab Kev Txhim Kho

 

Cov hlau kub dov yog ib qho ntawm cov khoom tseem ceeb ntawm cov hlau, siv dav hauv kev lag luam, kev ua liaj ua teb, kev thauj mus los thiab kev tsim kho, thiab tib lub sijhawm zoo li cov hlau txias dov,cov yeeb nkab vuam, cov hlau txias thiab lwm yam khoom siv raw rau kev tsim nws cov zis hauv Tuam Tshoj cov zis txhua xyoo ntawm cov hlau hauv tag nrho cov nyiaj ntawm ib feem loj dua ntawm lub luag haujlwm tseem ceeb hauv kev tsim cov hlau dov.

Nyob rau hauv cov teb chaws uas muaj kev lag luam loj hlob,phaj kub dovthiab cov hlau strip suav txog li 80% ntawm tag nrho cov zis ntawm cov hlau phaj thiab cov hlau strip, suav txog ntau dua 50% ntawm tag nrho cov hlau tsim tawm, thiab hauv kev sib tw ua lag luam thoob ntiaj teb hauv txoj haujlwm ua tus thawj coj.

Nyob rau hauv Suav teb, cov khoom siv hlau kub-kuav los ntawm cov hlau feem ntau, qhov txwv qis dua ntawm 1.8 hli tuab, tab sis qhov tseeb, muaj ob peb lub tuam txhab tsim cov hlau kub-kuav los ntawm cov hlau uas muaj qhov tuab tsawg dua 2.0 hli, txawm tias yog cov hlau nqaim, qhov tuab ntawm cov khoom feem ntau ntau dua 2.5 hli.

Yog li ntawd, ib feem loj ntawm kev cia siab tias cov neeg siv khoom siv cov ntawv ci uas tuab tsawg dua 2 hli yuav tsum siv cov ntawv ci txias.

 

Txias Rolled Sawb

Cov hlau uas dov txias: cov hlau uas kub dua qhov dov deformation hu ua dov txias, feem ntau yog hais txog cov hlau uas tsis tau cua sov thiab dov ncaj qha rau ntawm chav tsev kub. Cov kab txaij txias yuav kub rau qhov kov, tab sis nws tseem hu ua txias dov.

Kev tsim cov hlau dov txias tuaj yeem muab ntau qhov kev ua tau zoo thiab kev ua tau zoo ntawm cov hlau phaj thiab cov hlau strip, nws qhov tseem ceeb tshaj plaws yog qhov kub ua haujlwm qis, piv rau kev tsim cov hlau dov kub, nws muaj cov txiaj ntsig zoo li nram no:

(1) Cov khoom siv dov txias yog qhov tseeb hauv qhov loj me thiab sib xws hauv qhov tuab, thiab qhov sib txawv ntawm cov tuab ntawm cov kab feem ntau tsis pub ntau tshaj 0.01-0.03 hli lossis tsawg dua, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev ua siab raug.

(2) Cov kab nyias nyias uas tsis tuaj yeem tsim los ntawm kev dov kub tuaj yeem tau txais (qhov nyias tshaj plaws tuaj yeem txog li 0.001 hli lossis tsawg dua).

(3) Qhov zoo ntawm cov khoom dov txias yog qhov zoo dua, tsis muaj cov kab txaij kub feem ntau tshwm sim pitting, nias rau hauv cov hlau oxide thiab lwm yam tsis zoo, thiab tuaj yeem tsim raws li tus neeg siv xav tau ntawm qhov sib txawv ntawm qhov roughness ntawm cov kab txaij (qhov chaw ci lossis qhov chaw pitted, thiab lwm yam), txhawm rau pab txhawb kev ua cov txheej txheem tom ntej.

(4) Cov hlau nplaum txias muaj cov khoom siv kho tshuab zoo heev thiab cov txheej txheem ua haujlwm (xws li lub zog siab dua, qhov txwv qis dua, kev ua tau zoo kos duab tob, thiab lwm yam).

(5) Kev dov ceev ceev thiab kev dov tas mus li tuaj yeem ua tiav, nrog rau kev tsim khoom siab.

Kev faib tawm ntawm cov hlau nplaum txias

Cov hlau nplaum txias tau muab faib ua ob hom: dub thiab kaj.

(1)dub annealed strip: txias dov strip ncaj qha rhuab mus rau qhov kub annealing, qhov xim ntawm qhov chaw vim yog qhov kub siab raug rau huab cua dub. Cov khoom siv lub cev ua mos, feem ntau siv rau cov hlau strip thiab tom qab ntawd txuas ntxiv siab, stamping, deformation ntawm qhov ua tiav tob dua.

(2) ci ntsa iab annealed strip: thiab dub annealed qhov sib txawv loj tshaj plaws yog tias qhov cua sov tsis sib cuag nrog huab cua, nrog nitrogen thiab lwm yam roj inert tau tiv thaiv, qhov xim nto kom tswj thiab txias dov strip, ntxiv rau qhov dub annealed siv kuj siv rau qhov chaw ntawm qhov chaw ntawm nickel plating thiab lwm yam kev kho mob nto, zoo nkauj thiab dav.

Qhov sib txawv ntawm cov hlau ci ntsa iab thiab cov hlau dub uas ploj mus: cov khoom siv kho tshuab yuav luag zoo ib yam, cov hlau ci ntsa iab yog nyob rau hauv cov hlau dub uas ploj mus raws li ntau dua ib kauj ruam ntawm kev kho kom zoo nkauj.

Kev Siv: cov hlau dub fading feem ntau yog ua rau cov khoom kawg ua ntej zoo los ua qee qhov kev kho kom zoo nkauj, cov hlau ci ntsa iab tuaj yeem raug ntaus ncaj qha rau hauv cov khoom kawg.
