Kusenokuba yimfuneko kumacandelo angenamngxunya angenamthungo anobunzima bodonga ngaphezulu kwe-10 mm, okanye xa iT/D ingaphezulu kwe-0,1, ukusebenzisa ukupholisa okukhawulezileyo emva kokwenza i-austenitizing ukufezekisa ubume obucetyiweyo, okanye ukucinywa kolwelo kunye nokufudumeza ukufikelela komatshini ochaziweyo. iipropati.
Kumacandelo angenamgongxo anobunzima bodonga obudlula i-10 mm, okanye xa i-T/D ingaphezulu kwe-0.1, ukupholisa okukhawulezileyo emva kokwenziwa kwe-austenitization kunokufuneka ukuphumeza isakhiwo esinqwenelekayo, okanye ukucinywa kolwelo kunye nokufudumeza ukufikelela kwiipropati ezichaziweyo zoomatshini.
Ukubunjwa kwemichiza ye-BS EN 10210
Iintsimbi ze-non-alloy - Ukubunjwa kweekhemikhali
Fine Grain Steels - Ukubunjwa kwemichiza
Xa kumiselwa i-CEV le fomyula ilandelayo iya kusetyenziswa:
CEV=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15
Ukutenxa ekuBumbeni kweMichiza
IiPropati zoomatshini ze-BS EN 10210
Ukuthomalalisa uxinzelelo kuxinzelelo olungaphezulu kwama-580 °C okanye ngaphezulu kweyure enye kunokukhokelela ekuwohlokeni kweempawu zoomatshini.
Iintsimbi ze-non-alloy - iiPropati zoomatshini
Fine Grain Steels - Mechanical Properties
Iimvavanyo zempembelelo
Uvavanyo lwempembelelo alufunwa xa ubukhulu obuchaziweyo < yi-6 mm.
Iisampulu ezikumgangatho oqhelekileyo we-V ngokwe-EN 10045-1 ziya kusetyenziswa.
Ukuba ubukhulu bemveliso yegama abunelanga ukulungiselela imizekelo esemgangathweni, iimvavanyo ziya kuqhutywa kusetyenziswa imizekelo enobubanzi obungaphantsi kwe-10 mm, kodwa ingabi ngaphantsi kwe-5 mm.
Ukuweldability
Iintsimbi kwi-BS EN 10210 ziyakwazi ukuwelda.
I-EN 1011-1 kunye ne-EN 1011-2 ichaza iimfuno ngokubanzi kwiimveliso ezidityanisiweyo.
Ukuqhekeka okubandayo kwindawo ye-weld ngowona mngcipheko uphambili njengoko ubukhulu bemveliso, inqanaba lamandla, kunye nokunyuka kwe-CEV.
Ukunyamezelwa kweDimensional
Ukunyamezelana kwiMilo, ukuTwa kunye noMisa
Ukunyamezela Ubude
Umthungo Ubude be-SAW Weld
Ukunyamezelana kubude bomthungo we-weld wangaphakathi nangaphandle we-arc entywiliselwe amacandelo aholoholo.
| Ukutyeba, T | Ubude be-weld bead, mm |
| ≤14,2 | 3.5 |
| >14,2 | 4.8 |
Umgangatho we-BS EN 10210 ugubungela zombini icandelo elingenamthungo kunye ne-welded eshushu eligqityiweyo.Iinkqubo ze-welding eziphambili zi-resistance welding (ERW) kunye ne-arc welding ephantsi kwamanzi (SAW).I-welds kwimibhobho yensimbi ye-ERW ayibonakali kakhulu, ngelixa ii-welds ze-SAW zihlala zirhabaxa kwaye zibonakala ngakumbi ngenxa ye-SAW.
Imbonakalo yoMphezulu
Umphezulu uya kuba nesiphelo esigudileyo esihambelana nendlela yokuvelisa esetyenzisiweyo;
Ukuba ubukhulu bungaphakathi kokunyamezela, ama-bumps, grooves, okanye i-grooves e-shallow longitudinal ephuma kwinkqubo yokuvelisa ivumelekile.
Iigalvanized
Iimveliso kwi-BS EN 10210 zilungele unyango lwediphu eshushu.
I-EN ISO 1461 kufuneka isetyenziswe ukucacisa iimfuno zokugquma.
Iingubo ze-Zinc zisetyenziselwa ukucwiliswa kwisisombululo esityhidiweyo esiqulethe ubuncinane i-98% ye-zinc content.
Ukulungiswa kweziphene zoMphezulu
Iziphene zobuso zingasuswa ngokusila ngumvelisi, ngaphandle kokuba ubungqingqwa obulungisiweyo abukho ngaphantsi kobuncinci obuvumelekileyo.
Ukuba yenziwe yinkqubo ye-welding, ukulungiswa kwee-welds akuvumelekanga ngaphandle kwe-arc welding ephantsi kwamanzi.
Umbhobho wentsimbi ongeyo-alloyi unokulungiswa ngokuwelda umzimba wombhobho.Umbhobho wentsimbi yealloyi awunakulungiswa ngokuwelda umzimba.
I-BS EN 10210 Ukumakisha
Imixholo yokumakishwa kombhobho wentsimbi kufuneka iqulathe:
ligama lentsimbi, umz. EN 10210-S275JOH.
ligama okanye uphawu lokuthengisa lomenzi.
ikhowudi yokuzazisa, umz. inombolo ye-odolo.
I-TS EN 10210 iityhubhu zensimbi zinokumakishwa ngeendlela ezahlukeneyo zokuqinisekisa ukuchongwa ngokulula kunye nokulandeleka, nokuba kupeyinti, isitampu, iileyibhile ezincamathelayo, okanye iilebhile ezongezelelweyo, ezinokusetyenziswa ngokwahlukeneyo okanye ngokudibeneyo.
Usetyenziso
