Qhov sib txawv ntawm txias-kuav los tiag thiab kub-kuav los tiag carbon steel

Hauv kev lag luam steel, peb feem ntau hnov ​​lub tswv yim ntawm kev kub dov thiab txias dov, yog li lawv yog dab tsi?

Lub dov ntawm cov hlau yog tsuas yog ua raws li kub dov, thiab txias dov yog tsuas yog siv rau kev tsim cov duab me me thiab nplooj ntawv.

 

Cov hauv qab no yog cov khaub thuas dov thiab kub dov ntawm steel:

Hlau: Txoj kab uas hla 5.5-40 mm, coil zoo, tag nrho cov khoom kub dov.Tom qab kos duab txias, nws yog txias kos.

Round steel: Ntxiv rau qhov loj me me ntawm cov khoom siv ci yog feem ntau kub dov, kuj tseem muaj forged (nto forging marks).

Sawb steel: Ob qho tib si kub thiab txias dov, cov khoom siv txias dov feem ntau yog thinner.

Hlau phaj: txias-dov phaj yog feem ntau nyias, xws li automotive phaj;Muaj ntau daim hlau tuab hauv kub dov, nrog cov tuab zoo sib xws rau txias dov, thiab cov tsos yog pom tseeb txawv.

Lub kaum sab xis steel: Tag nrho cov kub dov.

Hlau yeeb nkab: welded kub dov thiab txias kos.

Channel thiab H-shaped steel: kub dov.

Rebar: kub dov khoom.

 

Kub dov thiab txias dov yog cov txheej txheem ntawm steel phaj lossis profile forming, uas muaj kev cuam tshuam zoo rau cov qauv thiab cov khoom ntawm cov hlau.

Cov dov ntawm cov hlau yog tsuas yog ua raws li kub dov, thiab txias dov feem ntau tsuas yog siv rau kev tsim cov hlau precision xws li cov hlau me thiab cov ntawv hlau.

Qhov ntsuas kub ntawm qhov kub dov feem ntau yog 800 ~ 900 ° C, thiab tom qab ntawd nws feem ntau txias hauv huab cua, yog li lub xeev kub dov yog sib npaug rau normalizing kev kho mob.

Feem ntau ntawm cov hlau yog dov los ntawm kub dov.Cov hlau xa tawm hauv lub xeev kub dov, vim qhov kub thiab txias, ua rau txheej txheej ntawm oxide ntawv rau ntawm qhov chaw, yog li nws muaj qee yam corrosion kuj thiab tuaj yeem khaws cia hauv huab cua qhib.

Txawm li cas los xij, txheej txheej ntawm oxide no kuj ua rau saum npoo ntawm kub dov hlau ntxhib, qhov hloov pauv loj yog qhov loj, yog li nws yuav tsum tau du nto, qhov loj me, cov khoom siv zoo ntawm cov hlau, siv cov khoom kub dov semi-tiav lossis tiav. cov khoom ua raw khoom thiab ces txias dov ntau lawm.

 

Qhov zoo:

Lub molding ceev ceev, cov zis yog siab, thiab cov txheej tsis puas, thiab nws tuaj yeem ua rau ntau hom ntawv hla ntu kom tau raws li qhov xav tau ntawm kev siv;Txias dov tuaj yeem tsim cov yas deformation zoo ntawm cov hlau, yog li ua rau cov khoom xa tawm ntawm cov hlau.
