Chitsulo, kuphatikizapo zida zachitsulo, zimayesedwa kuti zikhale zabwino m'njira zosiyanasiyana, kuphatikizapo kuyesa kwamphamvu, kuyesa kutopa, kupindika / kupindika komanso kuyesa kukana kwa dzimbiri.Zida ndi zinthu zokhudzana nazo zitha kupangidwa ndikupangidwa munthawi yeniyeni kuti muzitha kuyang'anira momwe zinthu zimagwirira ntchito, zomwe zingapewe kubweza chifukwa chaubwino komanso kuwononga zida.
Pali mitundu ingapo yodziwika bwino yachitsulo.
Chitsulo cha Carbon
Chitsulo cha kaboni, chomwe chimadziwikanso kuti chitsulo cha kaboni, ndi aloyi yachitsulo-carbon yomwe imakhala ndi mpweya (wc) wosakwana 2%.Kuphatikiza pa kaboni, chitsulo cha kaboni nthawi zambiri chimakhala ndi silicon, manganese, sulfure ndi phosphorous pang'ono.
Mpweya zitsulo akhoza kugawidwa m'magulu atatu: mpweya structural chitsulo, mpweya chida zitsulo ndi ufulu-kudula structural zitsulo.Mpweya structural zitsulo angathenso kugawidwa mu mitundu iwiri ya zitsulo structural zomangamanga ndi makina kumanga.
Malinga ndi okhutira mpweya akhoza kugawidwa mu otsika mpweya zitsulo (WC ≤ 0,25%), mpweya zitsulo (WC 0,25% ~ 0,6%) ndi mkulu mpweya zitsulo (WC> 0,6%).Malinga ndi phosphorous, okhutira sulfure akhoza kugawidwa mu wamba mpweya zitsulo (wokhala phosphorous, sulfure apamwamba), apamwamba mpweya zitsulo (muli phosphorous, sulfure m'munsi) ndi zapamwamba zitsulo (munali phosphorous, sulfure m'munsi).
Kukwera kwa mpweya wa carbon mu zitsulo zonse za carbon, kumapangitsanso kuuma ndi mphamvu, koma pulasitiki imachepetsedwa.
Zitsulo za carbon structural
Chitsulo chamtunduwu makamaka kuti chiwonetsetse kuti makinawo ali ndi makina, kotero kuti kalasi yake ikuwonetseratu makina ake, ndi nambala za Q +, pamene "Q" pamtundu wa "Qu" wa chiyambi cha Hanyu Pinyin, chiwerengerocho chimasonyeza mtengo wamtengo wapatali, mwachitsanzo, Q275 idati zokolola za 275MPa.Ngati kalasiyo yalembedwa ndi zilembo A, B, C, D, zikutanthawuza kuti khalidwe la kalasi yachitsulo ndi losiyana, lomwe lili ndi kuchuluka kwa S, P pofuna kuchepetsa kuchuluka kwa zitsulo kuti zitheke.Ngati chilembo "F" chalembedwa kuseri kwa kalasi, ndi chitsulo chowira, cholembedwa "b" chachitsulo chokhazikika, chosalembedwa "F" kapena "b" pazitsulo zokhala pansi.Mwachitsanzo, Q235-AF imatanthawuza A-grade zitsulo zowiritsa zokhala ndi zokolola za 235 MPa, ndipo Q235-c imatanthauza c-grade quiescent zitsulo ndi mfundo zokolola za 235 MPa.
Zitsulo zopangidwa ndi kaboni nthawi zambiri zimagwiritsidwa ntchito popanda kutentha komanso momwe zimaperekedwa mwachindunji.Nthawi zambiri zitsulo za Q195, Q215 ndi Q235 zimakhala ndi kagawo kakang'ono kakang'ono ka carbon, katundu wabwino wowotcherera, pulasitiki wabwino ndi kulimba, zimakhala ndi mphamvu zina, ndipo nthawi zambiri zimakulungidwa m'mbale zopyapyala, mipiringidzo, mapaipi achitsulo, ndi zina zotero, zomwe zimagwiritsidwa ntchito mu milatho, nyumba ndi zomangira zina ndi kupanga rivets wamba, zomangira, mtedza ndi mbali zina.Zitsulo za Q255 ndi Q275 zimakhala ndi gawo lokwera pang'ono la kaboni, mphamvu yayikulu, pulasitiki yabwinoko komanso kulimba, imatha kuwotcherera, ndipo nthawi zambiri imakulungidwa. monga ndodo zolumikizira, magiya, zolumikizira ndi mapini.
