Koj puas paub qhov cuam tshuam ntawm cov khoom siv hluav taws xob ntawm kub dov steel kauj?

Thaum tsim tawmkub dov steel coils, Nws yog ib qho tseem ceeb kom nkag siab txog yam uas cuam tshuam rau nws cov khoom siv kho tshuab.Ib qho tseem ceeb uas tsis tuaj yeem tsis quav ntsej yog cua sov.Cov cua kub thiab txias txias ntawm steel coils ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab tag nrho cov khoom zoo thiab kev ua haujlwm ntawm steel coils.Hauv tsab xov xwm no peb ua tib zoo saib cov txiaj ntsig ntawm cov cua sov ntawm cov khoom siv hluav taws xob ntawm prime tshiab kub dov steel kauj.
Thawj qhov cuam tshuam los ntawm kev siv thermal yog tus nqi hrc steel.Thermal processing feem ntau xav tau lub zog ntxiv thiab cov cuab yeej tshwj xeeb, uas tuaj yeem cuam tshuam tus nqi kawg ntawm cov khoom.Txawm li cas los xij, qhov tseem ceeb ntawm cov kev kho mob no yog tias lawv muab cov khoom kho kom zoo dua qub.Los ntawm kev xa cov hlau coils mus rau cov txheej txheem cua sov thiab cua txias, nws muaj peev xwm hloov nws cov qauv thiab ua kom nws tag nrho lub zog, hardness thiab ductility.
Prime kub dov hlau hauv coils, tshwj xeeb tshaj yog cov uas ua los ntawm Q235B steel, tau txais kev kho cua sov kom zoo kom zoo rau lawv cov khoom siv kho tshuab.Cov txheej txheem kev kho cua sov yuav tsum ua kom sov lub kauj mus rau qhov kub thiab txias (feem ntau saum nws qhov kub ntawm recrystallization) thiab tom qab ntawd sai sai quenching.Qhov txias txias sai no pab ua kom tiav cov qauv zoo hauv cov hlau, uas ua rau kom muaj zog thiab tawv.
Mechanical Properties ntawmprime kub dov steel ntawv nyob rau hauv coils q235bkuj raug cuam tshuam los ntawm qhov txias txias tom qab cov txheej txheem cua sov.Kev ua kom txias qeeb ua rau tsim cov qauv coarse-grained, uas cuam tshuam rau cov neeg kho tshuab lub zog ntawm cov hlau.Ntawm qhov tod tes, kev ua kom txias sai sai pab kho cov qauv nplej thiab txhim kho tag nrho cov khoom siv kho tshuab.

Yuav kom ntseeg tau qhov zoo tshaj plaws, nws yog ib qho tseem ceeb uas yuav tsum tau ua hauj lwm nrog cov neeg muag khoom muaj npe nrov uas ua raws li cov qauv tsim khoom nruj.Los ntawm tau txais cov ntawv kub dov steel hauv coil prime los ntawm cov chaw tsim khoom ntseeg siab, koj tuaj yeem ntseeg siab ntawm qhov sib xws thiab kev ntseeg siab ntawm koj cov khoom siv hlau.Tsis tas li ntawd, cov neeg muag khoom txhim khu kev qha feem ntau tuaj yeem muab cov nqi sib tw rau lawv cov khoom yam tsis muaj kev cuam tshuam rau qhov zoo.
Hauv cov ntsiab lus, cua sov ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov khoom siv hluav taws xob ntawm kub dov steel coils.Los ntawm kev tswj cov cua sov thiab cua txias, lub zog, hardness thiab ductility ntawm cov hlau tuaj yeem ua kom zoo dua.Nws yog ib qho tseem ceeb uas yuav tau xaiv tus neeg muag khoom uas muaj qhov tseem ceeb ntawm qhov zoo thiab qhov sib xws thaum tsim cov kub kub dov steel coils.Los ntawm kev ua qhov no, koj xyuas kom meej tias koj tau txais cov khoom zoo tshaj plaws ntawm tus nqi sib tw tshaj plaws.
