Kub-dov hlau thiab txias-dov hlau yog cov khoom siv hlau, thiab muaj qhov sib txawv ntawm lawv cov txheej txheem tsim khoom thiab cov yam ntxwv ua haujlwm. Cov hauv qab no yuav qhia kom meej tias vim li cas cov hlau kub-kuav los tiag thiab txias-kuav los tiag steel yuav tsum tau qhov txawv, thiab piav qhia qhov txawv ntawm lawv.

1. Cov txheej txheem ntau lawm: Kub-kuav los tiag steel yog tsim los ntawm cua sov lub billet mus rau ib tug high-kub lub xeev thiab ces dov nws tsis tu ncua. Cov txheej txheem no hloov cov duab thiab qhov loj ntawm cov hlau thiab txo cov kev ntxhov siab sab hauv. Nyob rau hauv sib piv, txias-dov hlau yog tsim los ntawm dov kub-dov hlau nyob rau hauv chav tsev kub, deforming nws los ntawm lub siab yam tsis tau hloov nws kub. Kev tsim cov txheej txheem ntawm cov hlau txias txias yuav tsum muaj cov txheej txheem ntau dua thiab cov khoom siv, yog li tus nqi kuj tseem siab.

2. Cov qauv tsim thiab kev ua haujlwm:
Vim muaj cov txheej txheem ntau lawm, kuj tseem muaj qhov sib txawv ntawm cov qauv tsim thiab cov khoom ntawm cov hlau kub-kuav los tiag thiab txias-dov hlau. Cov nplej ntawm kub-kuav los tiag steel yog loj dua thiab loosely teem. Nws muaj siab plasticity thiab toughness thiab haum rau lub sijhawm uas yuav tsum tau muaj zog dua thiab hnav tsis kam. Cov nplej ntawm cov khaub thuas-kuav los tiag steel yog finer thiab ntau nyob ze, nrog ntau zog thiab hardness, thiab yog haum rau daim ntaub ntawv uas yuav tsum tau ntau dua precision thiab nto smoothness.

3. Nto zoo:
Kub-dov hlau yog nquag oxide nplai thiab xeb thaum lub sijhawm tsim khoom, yog li nws qhov zoo ntawm qhov chaw tsis zoo. Txij li thaum txias-dov hlau yog tsim nyob rau hauv chav tsev kub, nws muaj peev xwm zam lub tiam ntawm oxide nplai thiab xeb thiab muaj zoo nto zoo. Qhov no ua rau txias-kuav los tiag steel dav siv nyob rau hauv kev lag luam uas yuav tsum tau zoo heev nto zoo, xws li tsheb tsim thiab khoom siv hauv tsev.

4. Daim ntawv thov teb:
Vim qhov sib txawv ntawm cov khoom thiab qhov zoo ntawm qhov kub-kuav los tiag steel thiab txias-kuav los tiag steel, lawv muaj lawv qhov zoo hauv ntau daim ntawv thov. Kub-kuav los tiag steel feem ntau yog siv nyob rau hauv lub tsev, pipelines, loj machinery manufacturing, thiab lwm yam teb. Nws lub siab plasticity thiab toughness tuaj yeem ua tau raws li qhov xav tau ntawm cov kev ntxhov siab ib puag ncig. Cold-rolled steel yog dav siv hauv kev tsim tsheb, khoom siv hluav taws xob, khoom siv hauv tsev, aerospace, thiab lwm yam. Nws lub zog siab thiab qhov zoo ntawm qhov chaw tuaj yeem ua tau raws li kev ua tiav thiab cov khoom lag luam xav tau.

Saum toj no:
Muaj qhov sib txawv ntawm cov hlau kub-kuav los tiag thiab txias-kuav los tiag steel hauv cov txheej txheem tsim khoom, kev tsim qauv, kev ua haujlwm zoo, thiab daim ntawv thov. Kub-kuav los tiag steel muaj ntau dua plasticity thiab toughness thiab yog haum rau cov xwm txheej uas yuav tsum tau muaj zog dua thiab hnav tsis kam; thaum txias-dov hlau muaj zog dua thiab hardness thiab yog haum rau cov xwm txheej uas yuav tsum tau ntau dua precision thiab nto smoothness. Kev nkag siab txog lawv qhov sib txawv yuav pab kom raug xaiv thiab siv ob yam khoom no kom tau raws li qhov xav tau ntawm ntau qhov chaw.
