Qhov sib txawv ntawm txias-dov seamless steel yeeb nkab thiab kub dov seamless steel yeeb nkab Kub-kuav los tiag thiab txias-kuav los tiag steel yog tag nrho cov hlau los yog hlau tsim txheej txheem, lawv muaj kev cuam tshuam zoo rau lub koom haum thiab kev ua tau zoo ntawm cov hlau, steel dov tsuas yog kub dov. yog txoj hauv kev tseem ceeb, thiab txias dov tsuas yog siv rau kev tsim cov hlau me me thiab cov nplooj ntawv.
1. Kub dov qhov zoo: Nws tuaj yeem rhuav tshem cov ingot casting qauv, ua kom zoo dua cov nplej ntawm cov hlau, thiab tshem tawm qhov tsis xws luag ntawm microstructure, kom cov qauv hlau yog ntom thiab cov khoom siv kho kom zoo tuaj.Qhov kev txhim kho no feem ntau yog tshwm sim hauv cov kev taw qhia dov, kom cov hlau tsis yog isotropic lawm;rau ib qho twg, cov npuas, cov kab nrib pleb thiab looseness tsim thaum lub sij hawm pouring kuj yuav welded nyob rau hauv kub thiab siab.
Qhov tsis zoo: 1. Tom qab kub dov, cov khoom tsis yog xim hlau suav nrog (tsuas yog sulfides thiab oxides, thiab silicates) hauv cov hlau yog nias rau hauv cov ntawv nyias thiab cov txheej txheem (sandwich) tshwm sim.Stratification zoo heev degrades cov khoom ntawm cov hlau nyob rau hauv lub thickness kev taw qhia, thiab nws yog tau hais tias interlayer tearing tshwm sim thaum lub weld seam shrinks.Cov kab mob hauv cheeb tsam cuam tshuam los ntawm weld shrinkage feem ntau nce mus txog ob peb zaug ntawm cov kab mob ntawm qhov taw tes tawm, uas yog qhov loj dua li cov kab mob tshwm sim los ntawm kev thauj khoom;2. Kev ntxhov siab uas tshwm sim los ntawm qhov tsis sib xws.Residual stress yog qhov kev ntxhov siab ntawm kev sib npaug ntawm nws tus kheej-theem nyob rau hauv qhov kev txiav txim ntawm tsis muaj kev quab yuam sab nraud.Kub dov hlau ntawm ntau seem muaj xws li residual stress.Qhov loj dua qhov loj ntawm cov hlau dav dav, qhov ntau dua qhov kev ntxhov siab seem.Txawm hais tias qhov seem ntawm kev ntxhov siab yog qhov sib npaug ntawm tus kheej, nws tseem muaj qee qhov cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hlau nyob rau hauv sab nraud rog.Xws li deformation, stability, tiv thaiv qaug zog thiab lwm yam yuav muaj kev cuam tshuam tsis zoo.

Cold Rolling yog hais txog kev ua cov hlau phaj lossis strips rau hauv ntau hom hlau ntawm qhov txias txias los ntawm kev kos duab txias, txias khoov, kos duab txias, thiab lwm yam hauv chav sov.
Qhov zoo: kev sib sau ua haujlwm siab, siab yield, thiab tsis muaj kev puas tsuaj rau cov txheej txheem, tuaj yeem ua rau ntau hom ntawv sib dhos kom tau raws li qhov xav tau ntawm kev siv cov xwm txheej;txias dov tuaj yeem ua rau cov hlau tsim cov yas loj deformation, yog li ua kom cov qoob loo ntawm cov hlau taw tes.
Qhov tsis zoo: 1.Txawm hais tias tsis muaj cov yas kub compression hauv cov txheej txheem tsim, tseem muaj cov kev ntxhov siab nyob hauv seem, uas yuav cuam tshuam rau cov khoom ntawm cov hlau tag nrho thiab hauv zos buckling;2. Cold dov seem steel style feem ntau qhib seem, ua rau seem dawb Tsawg torsional txhav.Nws zoo li twist thaum khoov, khoov thiab torsion buckling yuav tshwm sim thaum compression, thiab torsion kuj tsis zoo.3. Cov phab ntsa tuab ntawm cov hlau uas ua rau txias txias yog qhov me me, thiab nws tsis yog thickened ntawm cov ces kaum uas cov phaj koom, thiab nws tuaj yeem tiv taus hauv cheeb tsam.Lub peev xwm kom concentrate loads tsis muaj zog.

Qhov sib txawv tseem ceeb ntawm kub thiab txias dov yog:
1. Cold-formed steels tso cai rau hauv zos buckling ntawm tus ntoo khaub lig-section kom lub post-buckling bearing muaj peev xwm yuav siv tau tag nrho;kub dov steels tsis tso cai rau lub zos buckling ntawm tus ntoo khaub lig-section.
2. Qhov ua rau muaj kev ntxhov siab nyob hauv cov hlau kub-kuav los tiag thiab txias-kuav los tiag steel yog sib txawv, yog li qhov kev faib tawm ntawm qhov hla ntu kuj txawv heev.Qhov seem kev ntxhov siab faib rau ntawm qhov txias-tsim nyias-phab ntsa seem hlau yog nkhaus, thaum seem kev ntxhov siab faib rau ntawm ntu kub los yog welded seem yog nyias-zaj duab xis.
3. Lub torsional rigidity ntawm kub-dov hlau yog siab dua li ntawm txias-kuav los tiag steel, yog li qhov torsional kev ua tau zoo ntawm cov hlau kub dov yog zoo dua li cov hlau txias-dov.
