1.Kodi Makalasi Otentha Kwambiri Azitsulo Zotentha
Chitsulo ndi aloyi yachitsulo yomwe imakhala ndi mpweya wochepa.Zogulitsa zitsulo zimabwera m'magiredi osiyanasiyana kutengera kuchuluka kwa kaboni zomwe zili.Magulu osiyanasiyana azitsulo amagawidwa malinga ndi zomwe zili mkati mwa carbon.Hot adagulung'undisa zitsulo makalasi amagawidwa m'magulu a carbon awa:
Chitsulo chochepa cha carbon kapena chofatsa chimakhala ndi 0.3% kapena kuchepera kwa carbon ndi voliyumu.
Chitsulo chapakati cha carbon chili ndi 0.3% mpaka 0.6% carbon.
Zitsulo zokhala ndi mpweya wambiri zimakhala ndi carbon yoposa 0.6%.
Zing'onozing'ono zazinthu zina zophatikizira monga chromium, manganese kapena tungsten zimawonjezedwa kuti apange zitsulo zambiri.Mitundu yosiyanasiyana yachitsulo imapereka zinthu zingapo zapadera monga kulimba kwamphamvu, ductility, malleability, durability, ndi matenthedwe ndi magetsi.
2.Kusiyana pakati pa Chitsulo Chotentha Chotentha ndi Cold Rolled Steel
Zinthu zambiri zachitsulo zimapangidwa m'njira ziwiri zazikulu: kugudubuza kotentha kapena kugudubuza kozizira.Hot adagulung'undisa zitsulo ndi mphero ndondomeko imene zitsulo ndi mpukutu mbamuikha pa kutentha kwambiri.Nthawi zambiri, kutentha kwa zitsulo zotentha kumapitirira 1700 ° F.Cold adagulung'undisa zitsulo ndi ndondomeko imene zitsulo mpukutu mbamuikha firiji.
Ndikofunika kuzindikira kuti zitsulo zonse zotentha komanso zitsulo zozizira sizili zitsulo.Ndiwo njira zopangira zinthu zomwe zimagwiritsidwa ntchito pazinthu zosiyanasiyana zachitsulo.
Njira Yachitsulo Yotentha Yotentha
Chitsulo chotentha chimaphatikizapo kupanga ndi kugubuduza zitsulozo kukhala mzere wautali ndikutenthedwa pamwamba pa kutentha kwake koyenera.Silabu yofiira-hot imadyetsedwa kupyolera mumagulu a mphero kuti ipangidwe ndikuyitambasula kukhala yopyapyala.Akamaliza kupanga, chingwe chachitsulocho chimazizidwa ndi madzi ndikuchipanga ngati koyilo.Mitundu yosiyanasiyana yoziziritsa madzi imapanga zinthu zina zazitsulo muzitsulo.
Normalizing otentha adagulung'undisa zitsulo pa firiji amalola kuonjezera mphamvu ndi ductility.
Chitsulo chotentha kwambiri chimagwiritsidwa ntchito pomanga, njanji zanjanji, zitsulo zachitsulo, ndi zina zomwe sizifuna kumaliza kokongola kapena mawonekedwe ake ndi kulolerana.
Njira ya Zitsulo Zozizira
Chitsulo chozizira chimatenthedwa ndikuzizidwa ngati chitsulo chopindika chotentha koma kenako chimakonzedwanso pogwiritsa ntchito annealing kapena kupiringitsa kupsya mtima kuti ukhale wolimba kwambiri komanso kuti ukhale wolimba.Ntchito yowonjezera ndi nthawi yokonza imawonjezera mtengo koma imalola kulolerana kwapafupi ndikupereka njira zambiri zomaliza.Chitsulo ichi chimakhala ndi mapeto osalala ndipo chimagwiritsidwa ntchito pazinthu zomwe zimafuna malo enieni komanso kulolerana kwapakati.
Zomwe zimagwiritsidwa ntchito nthawi zambiri pazitsulo zoziziritsa kuzizira zimaphatikizapo zida zomangira, mipando yachitsulo, zida zapanyumba, zida zamagalimoto ndi ntchito zaukadaulo pomwe kulondola kapena kukongola ndikofunikira.
3.Makalasi Achitsulo Otentha Otentha
Chitsulo chotentha chimapezeka m'makalasi angapo kuti chikwaniritse zomwe mukufuna.American Society for Testing and Materials (ASTM) kapena Society of Automotive Engineers (SAE) imayika miyezo ndi magiredi molingana ndi kapangidwe ka chitsulo chilichonse ndi kuthekera kwake.
Magiredi achitsulo a ASTM amayamba ndi chilembo "A" chomwe chimayimira zitsulo zachitsulo.The SAE grading system (yomwe imadziwikanso kuti American Iron and Steel Institute kapena AISI system) imagwiritsa ntchito nambala ya manambala anayi pogawa.Makalasi achitsulo cha carbon plain mu dongosolo lino amayamba ndi chiwerengero 10, kutsatiridwa ndi mitundu iwiri yosonyeza kuchuluka kwa mpweya.
Zotsatirazi ndizofala zachitsulo chokulungidwa chotentha.Chonde dziwani kuti zinthu zina zimaperekedwa munjira zonse zotentha komanso zozizira.
A36 Chitsulo Choyaka Choyaka
Chitsulo chotentha cha A36 ndi chimodzi mwazitsulo zodziwika bwino zomwe zimapezeka (zimabweranso mumtundu wozizira, womwe ndi wocheperako).Chitsulo chochepa cha carbon ichi chimakhala ndi mpweya wochepera 0.3% polemera, 1.03% manganese, 0.28% silikoni, 0.2% yamkuwa, 0.04% phosphorous, ndi 0.05% sulfure.Ntchito wamba A36 zitsulo mafakitale ntchito monga:
Mafelemu agalimoto
Zida zaulimi
Shelving
Masamba, mikwingwirima, ndi mikwingwirima
Thandizo lachimangidwe
Makalavani
Zopeka zambiri
1018 Hot Rolled Carbon Steel Bar
Pafupi ndi A36, AISI/SAE 1018 ndi imodzi mwasukulu zodziwika bwino zachitsulo.Nthawi zambiri, kalasi iyi imagwiritsidwa ntchito m'malo mwa A36 pamitundu yama bar kapena mizere.Zida zachitsulo za 1018 zimabwera m'mitundu yonse yotentha komanso yozizira, ngakhale kuzizira kozizira kumagwiritsidwa ntchito kwambiri.Mabaibulo onsewa ali ndi mphamvu komanso kuuma bwino kuposa A36 ndipo ndi oyenera kugwira ntchito zozizira, monga kupindika kapena kupindika.1018 ili ndi 0.18% yokha ya carbon ndi 0.6-0.9% ya manganese, yomwe ili yochepa kuposa A36.Mulinso zotsalira za phosphorous ndi sulfure koma zosafunika zochepa kuposa A36.
Zomwe zimagwiritsidwa ntchito pazitsulo za 1018 zikuphatikizapo:
Magiya

Chitsulo chotentha cha ASTM A513
Mafotokozedwe a ASTM A513 ndi machubu otentha a zitsulo za kaboni.Machubu achitsulo otentha amapangidwa podutsa zitsulo zotenthetsera kudzera m'ma roller kuti akwaniritse kukula kwake.Chomalizidwacho chimakhala ndi mawonekedwe owoneka bwino okhala ndi ngodya zotalikirana komanso zomangira zowotcherera kapena zopanda msoko.Chifukwa cha izi, chubu chachitsulo chowotcha chimakhala choyenera kwambiri pazogwiritsa ntchito zomwe sizifuna mawonekedwe enieni kapena kulolerana kolimba.
Hot adagulung'undisa zitsulo chubu ndi yosavuta kudula, kuwotcherera, mawonekedwe, ndi makina.Amagwiritsidwa ntchito m'mafakitale ambiri, kuphatikizapo:
Zokwera injini

Chitsulo chotentha cha ASTM A786
Chitsulo chotentha cha ASTM A786 chimatenthedwa ndi mphamvu yayikulu.Nthawi zambiri amapangidwira mbale zopondera zitsulo pazotsatira zotsatirazi:
Pansi
Msewu
1020/1025 Chitsulo Choyaka Choyaka
Zoyenera pakumanga ndi zomangamanga, chitsulo cha 1020/1025 chimagwiritsidwa ntchito kwambiri pazotsatira izi:
Zida ndi kufa
Zigawo zamakina
Zida zamagalimoto
Zida zamafakitale
Ngati mukuganiza zogula koyilo yoviringidwa yotentha, chinsalu chogudubuza chotentha, chopiringa chozizira, mbale yoziziritsa yozizira, onani zomwe JINDALAI ali nazo kwa inu ndipo lingalirani zofikira gulu lathu kuti mudziwe zambiri.Tidzakupatsani yankho labwino kwambiri la polojekiti yanu.Chonde khalani omasuka kulumikizana nafe.
