Zomangira Zitsulo Zosapanga dzimbiri: Makalasi Amphamvu ndi Zizindikiro
Zomangira zitsulo zosapanga dzimbiri ndizofunikira kwambiri pakuwonetsetsa kukhazikika komanso chitetezo chazinthu zamafakitale osiyanasiyana. Magiredi awo amphamvu ndi zolembera zimapereka chidziwitso chofunikira pakusankha zigawo zolondola za ntchito zinazake. Tiyeni tifufuze tanthauzo la mawuwa ndi zitsanzo zothandiza.
♦ Maphunziro Amphamvu
A2 - Chitsulo chosapanga dzimbiri cha Austenitic (304/304L)
Zomangira zolembedwa kuti "A2" zimatanthawuza chitsulo chosapanga dzimbiri cha austenitic, chomwe chimakhala giredi 304 kapena 304L, chomwe sichikhala ndi maginito ndipo chimapereka kukana kwa dzimbiri koyenera kugwiritsidwa ntchito wamba. Mwachitsanzo, chizindikiro cha "A2-70" chimasonyeza chomangira chopangidwa kuchokera kuzinthu izi chomwe chili ndi mphamvu zocheperapo pafupifupi 700 MPa. Nambala "70" imatanthawuza makamaka gulu lazinthu zamakina, kutanthauza kuti chomangira ichi chingathe kupirira zosachepera 700 MPa za kupsinjika kwamphamvu musanalephere.
Pantchito yomanga panja, ma bawuti a A2-70 atha kugwiritsidwa ntchito kutchingira zitsulo zachitsulo chifukwa amateteza ku dzimbiri kokwanira kwinaku akukhalabe ndi mphamvu zokwanira zamapangidwe.
A4 - Chitsulo chosapanga dzimbiri cha Austenitic (316/316L)
Matchulidwe a "A4" amalozera ku zitsulo zosapanga dzimbiri za austenitic zamtundu wapamwamba kwambiri monga 316 kapena 316L, zomwe zimadziwika kuti zimalimbana kwambiri ndi dzimbiri, makamaka m'malo am'madzi kapena am'madzi. Chizindikiro cha "A4-80" chimayimira chomangira chokhala ndi mphamvu yocheperako ya 800 MPa, kuwonetsa kuti idapangidwa kuti ikhale yamphamvu kwambiri pomwe mphamvu zonse ndi kukana dzimbiri ndizofunikira.
Akatswiri apanyanja atha kusankha zomangira za A4-80 zomangira boti chifukwa zomangira izi sizimangolimbana ndi dzimbiri lamadzi amchere komanso zimapatsa mphamvu zofunikira kuti zitsimikizire kuti zikuyenda bwino m'malo ovuta kwambiri apanyanja.
♦ Zizindikiro ndi Kuzindikiritsa
Miyezo ya ISO
Pansi pamiyezo ya International Organisation for Standardization (ISO), zolembera zomangira zimaphatikizanso zambiri zamtundu wazinthu ndi makina. Monga tawonera m'zitsanzo zathu, "A2-70" ndi "A4-80" zimapereka zidziwitso zomveka bwino za zinthu ndi mphamvu zake zogwirira ntchito.
Miyezo ya DIN
Mu dongosolo la Deutsches Institut für Normung (DIN), manambala osiyanasiyana amatha kuwonetsa makalasi azinthu ndi katundu. Ndikofunikira kutchula zikalata zoyenera kuti mutanthauzire molondola.
Zizindikiro Zowonjezera
Kupatula magiredi amphamvu, zomangira zimatha kukhala ndi zizindikiritso zina monga ma code opanga, manambala otenthetsera, kapena zizindikiro zowunikira monga CE, zosonyeza kutsata malamulo a European Union.
Kusankha chomangira chitsulo chosapanga dzimbiri choyenera kumaphatikizapo kumvetsetsa kalasi yazinthu komanso gulu lazinthu zamakina zomwe zikuwonetsedwa ndi zolembera. Poganizira zinthu monga kuwonetseredwa kwa chilengedwe ndi mphamvu zofunikira, munthu akhoza kusankha zomangira zomwe zimapangitsa kudalirika ndi moyo wautali wa msonkhano uliwonse.
Zikomo powerenga, ngati mukufuna kuwona zambiri zomwe timapereka mutha kutsatira maulalo pansipa!
