Kub dov thiab txias dov yog ob txheej txheem tseem ceeb hauv kev ua hlau. Lawv siv qhov sib txawv ntawm qhov kub thiab txias thaum lub sijhawm tsim khoom, uas ua rau muaj qhov sib txawv ntawm lub cev thiab cov tsos ntawm cov khoom kawg. Cov hauv qab no yog cov ncauj lus kom ntxaws txog ob txheej txheem no thiab lawv qhov sib txawv.
Ua ntej, cov txheej txheem kub dov yog nqa tawm ntawm qhov kub thiab txias. Lub steel billet yog rhuab saum lub recrystallization kub txog li 1100 degrees Celsius, thiab ces compressed ntau zaus los ntawm ib tug dov zeb. Vim qhov zoo plasticity thiab ductility ntawm cov hlau ntawm qhov kub thiab txias, kub dov tuaj yeem hloov pauv cov duab thiab qhov loj ntawm cov hlau, thiab muaj kev ua haujlwm ntau dua. Kub dov hlau feem ntau muaj qhov ntxhib saum npoo thiab qhov loj me me, tab sis vim muaj cov txheej txheem recrystallization, nws cov qauv hauv cov nplej yog qhov zoo thiab nws cov khoom siv kho mob kuj zoo ib yam.
Cov txheej txheem txias dov yog nqa tawm ntawm chav tsev kub. Cov hlau kub dov yog pickled kom tshem tawm oxide nplai, thiab tom qab ntawd compressed ntau zaus ntawm chav tsev kub siv lub tshuab txias txias. Cov txheej txheem txias dov tuaj yeem txhim kho qhov du du thiab qhov tseeb ntawm cov hlau, thiab ua kom nws muaj zog dua thiab tawv. Cold rolled steel feem ntau muaj ib tug du nto, me me me me tolerances, thiab zoo heev mechanical zog, tab sis vim ua hauj lwm hardening, nws plasticity thiab toughness yuav raug txo.
Hauv kev siv cov tswv yim, kub-kuav los tiag thiab txias-kuav los tiag steel muaj lawv tus kheej zoo thiab qhov tsis zoo, thiab kev xaiv cov txheej txheem tsim nyog nyob ntawm cov kev xav tau tshwj xeeb. Kub dov hlau yog dav siv nyob rau hauv cov teb xws li lub tsev tsim, mechanical manufacturing, thiab shipbuilding vim nws tsis tshua muaj nqi thiab zoo processability. Cold rolled steel, vim nws qhov zoo tshaj plaws saum npoo zoo thiab lub zog siab, feem ntau yog siv rau hauv kev tsim cov khoom siv high-precision, automotive panels, thiab cov khoom siv hauv tsev.
Qhov sib txawv ntawm kub-kuav los tiag thiab txias-kuav los tiag steel tuaj yeem sau los ntawm cov hauv qab no:
- Cov txheej txheem ntau lawm: Kub dov yog nqa tawm ntawm qhov kub thiab txias, thiab txias dov yog nqa tawm ntawm chav tsev kub.
- Qhov zoo ntawm qhov chaw: Qhov saum npoo ntawm cov hlau kub dov yog ntxhib, thaum lub ntsej muag txias-dov hlau yog du.
- Dimensional raug: Kub dov hlau muaj qhov loj dua qhov ntev, thaum txias dov hlau muaj qhov me me rau qhov ntev.
- Mechanical zog: Kub dov steel muaj zoo plasticity thiab toughness, thaum txias-dov hlau muaj zog dua thiab hardness.
- Daim ntawv thov thaj chaw: Kub dov hlau yog siv rau hauv kev tsim kho thiab kev tsim kho tshuab, thaum txias-dov hlau yog siv rau hauv high-precision thiab high-lub zog yuav tsum tau.
Los ntawm kev txheeb xyuas saum toj no, peb tuaj yeem nkag siab meej txog qhov sib txawv thiab qhov zoo ntawm cov hlau kub-kuav los tiag thiab txias-dov. Thaum xaiv cov hlau, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov hlau tsim nyog raws li cov kev thov tshwj xeeb thiab cov txheej txheem cov yam ntxwv, txhawm rau ua tiav cov txiaj ntsig zoo tshaj plaws.
