Qhov zoo thiab qhov tsis zoo ntawm kev kub dov

Ob qho tib si kub dov thiab txias dov yog cov txheej txheem rau kev tsim steel phaj lossis profiles, thiab lawv muaj kev cuam tshuam zoo rau cov qauv thiab cov khoom ntawm cov hlau.

Lub dov ntawm cov hlau yog tsuas yog ua raws li kub dov, thiab txias dov feem ntau tsuas yog siv los tsim cov hlau nrog qhov ntev xws li cov hlau thiab cov ntawv.

Qhov ntsuas kub ntawm qhov kub dov feem ntau yog 800 ~ 900 ℃, thiab tom qab ntawd nws feem ntau txias hauv huab cua, yog li lub xeev kub dov yog sib npaug rau normalizing kev kho mob.

Cov hlau feem ntau yog dov los ntawm txoj kev kub dov.Vim qhov kub thiab txias, cov hlau xa tawm hauv lub xeev kub dov muaj txheej txheej ntawm cov hlau oxide nplai rau ntawm qhov chaw, yog li nws muaj qee qhov kev tiv thaiv corrosion thiab tuaj yeem khaws cia hauv huab cua qhib.

Txawm li cas los xij, txheej txheej ntawm cov hlau oxide no kuj ua rau saum npoo ntawm cov hlau kub-kuav los tiag ntxhib thiab qhov luaj li cas fluctuates zoo heev.Yog li ntawd, cov hlau nrog du nto, qhov loj me thiab cov khoom siv zoo yog yuav tsum tau, thiab cov khoom kub-kuav los yog cov khoom tiav yog siv los ua cov khoom siv rau cov khoom siv txias txias.

qhov zoo:

Txoj kev sib sau ceev ceev, cov zis yog siab, thiab cov txheej txheem tsis raug puas, thiab nws tuaj yeem ua rau ntau yam ntawm cov ntawv hlais kom tau raws li cov kev xav tau ntawm kev siv;txias dov tuaj yeem ua rau cov yas loj deformation ntawm cov hlau, yog li ua kom cov txiaj ntsig ntawm cov hlau.

tsis txaus:

1. Txawm hais tias tsis muaj cov yas kub compression thaum lub sij hawm tsim cov txheej txheem, tseem muaj kev ntxhov siab nyob rau hauv seem, uas yuav inevitably cuam tshuam rau tag nrho thiab hauv zos buckling yam ntxwv ntawm cov hlau;

2. Cov style ntawm txias-kuav los tiag seem steel feem ntau yog ib qho qhib seem, uas ua rau cov dawb torsional nruj ntawm seem qis.Nws yooj yim rau torsion thaum nyob rau hauv khoov, nws yooj yim rau bending-torsional buckling nyob rau hauv compression, thiab tsis zoo torsional kev ua tau zoo;

3. Cov phab ntsa thickness ntawm txias-dov ua hlau yog me me, thiab nws tsis yog thickened ntawm cov ces kaum uas cov hlau txuas nrog, thiab lub peev xwm los tiv thaiv lub zos concentrated loads yog tsis muaj zog.
