Dab tsi yog qhov txawv ntawm Cov Khaub Ncaws Rolled Phaj Thiab Kub Rolled Phaj

Qhov sib txawv tseem ceeb ntawm cov ntawv txias-dov thiab kub-kuav los tiag yog raws li hauv qab no:
1. Cov xim sib txawv
Ob hom dov phaj yog txawv. Cov ntawv txias dov yog nyiaj, thaum cov phaj kub dov muaj xim ntau dua, qee qhov xim av.
2. Kev xav txawv ntawm tes
Cov ntawv txias dov muaj qhov muag muag thiab du, nrog cov npoo zoo nkauj thiab cov fab. Txawm li cas los xij, cov phaj kub-dov zoo nkaus li ntxhib rau qhov kov, thiab cov npoo thiab cov ces kaum tsis tau kho zoo heev.
3. Cov yam ntxwv sib txawv
Cov ntawv txias dov muaj lub zog siab thiab hardness, thiab cov txheej txheem tsim khoom yog qhov nyuaj, ua rau muaj tus nqi siab. Kub dov daim hlau muaj qis hardness, zoo ductility, yooj yim dua los tsim, thiab kuj pheej yig.
Kev soj ntsuam ntawm qhov zoo thiab qhov tsis zoo ntawm cov ntawv txias-dov thiab kub-kuav los tiag
Qhov tsis zoo ntawm cov ntawv kub dov yog tias qee cov sulfides, oxides, silicates, thiab lwm yam hauv cov hlau tom qab kub kub dov yuav raug nyem thiab thinned, ua rau tsis muaj fusion thiab delamination. Qhov teeb meem no yuav txo tau lub zog tensile ntawm cov hlau thiab tej zaum kuj yuav ua rau interlayer tawg thaum lub vuam taw tes shrinks. Qhov xwm txheej no ntau dua qhov kev siv zog los ntawm steel loads.
Qhov kom zoo dua ntawm cov ntawv kub dov yog tias lawv tau txais kev kub siab kub dov, uas tuaj yeem hloov kho cov qauv sab hauv ntawm cov hlau thiab ua rau cov nplej loj ntawm cov hlau zoo dua. Thiab nws tseem tuaj yeem hloov qhov tsis txaus ntawm cov qauv steel, ua rau lawv ruaj khov thiab compact. Zoo dua ductility thiab muaj zog load-bearing muaj peev xwm. Ntxiv mus, qee cov qauv uas twb muaj lawm, cov kab nrib pleb, thiab npuas hauv cov hlau tuaj yeem raug tshem tawm tag nrho los ntawm dov.
Qhov tsis zoo ntawm daim ntawv txias dov yog qhov tsis zoo elasticity, qhov nruab nrab ductility, thiab yooj yim torsion thaum raug khoov quab yuam. Nws yog qhov nyuaj los hloov nws cov duab. Thiab nws lub peev xwm thauj khoom kuj tseem me me. Kev siv kuj muaj kev txwv.
Qhov zoo ntawm cov ntawv txias dov yog kev ua haujlwm yooj yim, kev ua haujlwm yooj yim, thiab muaj peev xwm tsim tau hauv ntau. Nws yuav tsis ua rau cov txheej txheem tiv thaiv sab nraud ntawm cov hlau thiab tuaj yeem tsim ntau hom ntawm cov khoom tiav uas haum rau qhov sib txawv siv ib puag ncig. Nws cov ntsiab lus tawm los kuj tuaj yeem raug tsa, uas tuaj yeem hloov pauv nws cov yam ntxwv.
