Taw qhia ntawm Steel Rolling

 

Rolling yog hlau yas ua tshuab, ntawm no peb tsuas tham txog steel phaj dov. Hlau phaj dov yog txheej txheem uas nws lub hom phiaj yog txhawm rau txhawm rau txhawm rau tsim cov phaj hlau. Ob qhov kev faib tawm yog kub dov thiab txias dov. Qhov sib txawv tseem ceeb yog hauv qab no.

Classification: Kub Rolled Thiab Cold Rolled

 

 

Kub Rolled

Kub dov yog ib txoj hauv kev ua ntawm qhov kub ntawm recrystallization ntau dua li cov hlau phaj. Rolling steel phaj rau qhov xav tau loj. Cov hlau phaj uas tsim los ntawm cov txheej txheem ntau lawm no feem ntau yog cov qauv hlau los yog cov khoom siv hlau welded.

Pros

 

1

Qhov loj tshaj feature ntawm kub dov yog tias nws tuaj yeem dov nrog tsawg zog ntawm qhov kub thiab txias.

2

Kub dov tuaj yeem ua rau cov qauv siv lead ua ruaj khov thiab txhim kho lub toughness ntawm steel phaj.

3

Qhov ntsuas kub feem ntau yog 900-1200 degree thiab yuav tsis ua rau kev ua haujlwm hnyav.

Cons

 

1

Kub dov siv ib qho nqi ntawm cov nqi thiab lub zog.

2

Nyob rau hauv qhov kub thiab txias ib puag ncig, cov hlau phaj yog ib qho yooj yim los ua ke nrog cov pa oxygen hauv huab cua los tsim cov oxide zaj duab xis.

3

Vim yog thermal expansion thiab txias contraction, steel phaj tej zaum yuav muaj qhov txawv tsis zoo tom qab txias, uas cuam tshuam rau qhov tseeb ntawm cov phaj steel.

Txias Rolled

Txias dov yog txheej txheem dov ntawm cov hlau phaj ntawm chav tsev kub. Qhov zoo ntawm qhov chaw, qhov tsos thiab qhov tseeb ntawm qhov txias-kuav los tiag steel phaj yog superior rau cov kub-dov phaj.

 

Pros

 

1

Fast forming ceev thiab siab tso zis ntawm steel phaj.

2

Qhov saum npoo ntawm qhov txias-dov steel phaj yog du thiab ci.

3

Qhov txias-dov steel phaj muaj qhov tseeb qhov tseeb.

Cons

 

1

Qhov txias-dov steel phaj muaj siab hardness thiab tsis zoo formability.

2

Ua hauj lwm hardening yuav tshwm sim nyob rau hauv txias dov, thiab kev kho cua sov xws li annealing kuj yuav tsum tau.
