Hot adagulung'undisa koyilondi mbale yachitsulo yopangidwa kuchokera ku slabs yomwe imatenthedwa ndi kukulungidwa ndi mayunitsi ovuta komanso omaliza.Chitsulo chachitsulo chotentha chochokera ku mphero yomaliza chimakhazikika mpaka kutentha kwakhazikitsidwa ndi kutuluka kwa laminar kenako ndikukulungidwa muzitsulo zachitsulo ndi makina opangira.The utakhazikika zitsulo Mzere koyilo kukonzedwa mu mbale zitsulo, koyilo lathyathyathya ndi kotalika odulidwa zitsulo Mzere mankhwala kudzera mizere yomaliza (flattening, kuwongola, kudula mtanda kapena longitudinal kudula, kuyendera, kuyeza, ma CD ndi kulemba, etc.) zosowa za ogwiritsa ntchito.
China ndi dziko lalikulu sewerolo, ogula ndi kutumiza kunja zitsulo otentha adagulung'undisa, ndi linanena bungwe kufika matani 232 miliyoni mu 2015. Kukula kwa chitsulo ndi zitsulo makampani athandiza mogwira mtima patsogolo ndi mofulumira chitukuko cha chuma cha dziko la China, ndi kusintha kwa chuma cha dziko. kutulutsa ndi mtundu wa mbale yotenthetsera yopiringidwanso yakwaniritsa bwino zomwe zikukulirakulira kwa ntchito yomanga ku China, kupanga makina ndi mafakitale ena.
Chitsulo chotentha chokulungidwa mu koyilo nthawi zambiri chimakhala ndi zingwe zachitsulo zokhuthala, zopyapyala zopyapyala komanso mbale zopyapyala zotentha.
Mzere wachitsulo wokhuthala wapakati ndi umodzi mwamitundu yoyimira kwambiri, kupanga kwake kumatenga pafupifupi magawo awiri mwa atatu a zonse zomwe zimatuluka, Shanghai Futures Exchange posachedwa ipezeka mumgwirizano wam'tsogolo wamtsogolo womwe umakhala wa Mzere wachitsulo wokhuthala wapakati.
Mzere wachitsulo wokhuthala ndi wawukulu umatanthawuza Mzere wachitsulo wokhala ndi makulidwe a ≥3 mm ndi zosakwana 20 mm ndi m'lifupi mwake ≥600 mm, wopangidwa mopitilira muyeso wotakata zitsulo zopukutira kapena mphero za ng'anjo kapena zida zina, ndikuperekedwa. mu coils.
Mzere wopyapyala wotentha komanso wotambalala umatanthauza chingwe chachitsulo, chochindikala <3mm ndi m'lifupi mwake ≥600mm, chopangidwa ndi mphero zosalekeza zotakata kapena mphero zogudubuza m'ng'anjo kapena mphero zopyapyala za slab, ndi zina zambiri, ndikuperekedwa muzovala.
Hot adagulung'undisa pepala amatanthauza pepala limodzi lachitsulo ndi makulidwe <3 mm.Hot adagulung'undisa pepala zambiri amapangidwa mosalekeza yotakata Mzere mphero, mosalekeza kuponyera ndi Kugudubuza wa slabs woonda, etc., ndi kuperekedwa mu pepala mawonekedwe.
Mu 2023, zitsulo mbale otentha adagulung'undisa pafupifupi zaka makumi awiri kuyambira mphamvu kupanga kupanga kuchuluka mode, monga chakumapeto kwa 2023, otentha adagulung'undisa zitsulo pepala mu coils kupanga anafika matani 291,255,600, ndi kupanga kukula mlingo wa 11.01%.2023 otentha adagulung'undisa koyilo zitsulo kupanga kuposa rebar (2023 kupanga matani 260 miliyoni), analumphira ku China woyamba zitsulo mitundu.
Pamayendedwe akusintha kwapachaka, m'zaka zisanu zapitazi, kupanga mapepala otentha ndi koyilo kukuwonetsa kuwonjezeka kwa chaka ndi chaka, ndipo kukula kuchokera pa 2.57% mu 2019, kudakwera mpaka 11.01% mu 2023. , chiwongola dzanja chawonjezeka ndi 8.51 peresenti.
Kupanga kwa mwezi ndi mwezi kwa zitsulo zopindika zotentha mu 2023 ndizokwera kwambiri m'mbiri.Chifukwa cha kukula mlingo wa 11.01% mu 2023, kupitirira kwambiri mphamvu kukula mlingo wa 3%, otentha adagulung'undisa koyilo zitsulo mphero magwiritsidwe ntchito mlingo unawonjezeka kufika 84,7%, 6.11 peresenti mfundo kuposa mu 2022. Izi zikusonyeza kuti msika mkulu kupanga mode makamaka chaka chonse.
1.Zomangamanga: Zitsulo zachitsulo zotentha zimagwiritsidwa ntchito ngati zinthu zomangira nyumba, monga zitsulo, aluminiyamu ndi mapepala achitsulo omwe amagwiritsidwa ntchito popanga madenga, makoma ndi pansi.Zidazi nthawi zambiri zimakhala ndi mphamvu zambiri komanso kukana dzimbiri ndipo zimatha kukwaniritsa zosowa za nyumba mumitundu yosiyanasiyana yachilengedwe.
2.Kupanga magalimoto: Magalimoto ndi malo enanso ogwiritsira ntchito ma coils a HRC.Amagwiritsidwa ntchito popanga zinthu monga matupi agalimoto, zitseko, hood, madenga ndi chassis.Makampani opanga magalimoto ali ndi zofunika kwambiri pazida zokhala ndi mphamvu zambiri, zolimba komanso kukana dzimbiri, zonse zomwe ndi mawonekedwe a koyilo yowotcha.
3.Kupanga zida zapanyumba: Zida zambiri zapakhomo, monga firiji, makina ochapira, uvuni wa microwave ndi zoziziritsa mpweya, zimafunikira kugwiritsa ntchito koyilo yotentha ngati chomangira.Zidazi nthawi zambiri zimafunika kukhala ndi mapeto abwino a pamwamba, komanso makina apamwamba komanso kukana kwa dzimbiri.
4.Kupanga katundu: katundu wina wa katundu, monga mabokosi a aluminiyamu, katundu, zipolopolo zonyamula katundu, ndi zina zotero, zimagwiritsanso ntchito koyilo yotentha ngati chinthu.Koyilo yotentha yotentha ndi yopepuka, yolimba, ndipo imatha kukwaniritsa zonyamula katundu pakupepuka komanso kulimba kwazinthu zofunikira.
5.Kupanga makina: m'makampani opanga makina, koyilo yotentha yotentha imagwiritsidwa ntchito kwambiri popanga zida zamakina ndi zida, monga ma racks, mafelemu othandizira, slider, njanji ndi zina zotero.Zigawozi ziyenera kukhala ndi mphamvu zambiri komanso kukana kuvala, ndipo ma coil a HRC amatha kukwaniritsa izi.
Ponseponse, ma coil opiringizika otentha amakhala ndi ntchito zosiyanasiyana pomanga, magalimoto, zida zapakhomo, zikwama ndi kupanga makina.Amakhala ndi zida zabwino zamakina komanso kukana kwa dzimbiri ndipo amatha kukwaniritsa zofunikira zazinthu m'magawo osiyanasiyana, kotero amakondedwa kwambiri ndi makasitomala.Ngati mukufuna kugula gulani zitsulo zotentha zotentha, talandirani kuti mutilankhule.
