Nkhani - Zofunika Kwambiri ndi Katundu wa Koyilo Yachitsulo Yotentha Yotentha: Kuchokera Kupanga Mpaka Kugwiritsa Ntchito

M'makampani akuluakulu azitsulo,otentha adagulung'undisa zitsulo koyiloimagwira ntchito ngati maziko, omwe amagwiritsidwa ntchito kwambiri m'magawo monga zomangamanga, kupanga makina, ndi makampani opanga magalimoto. Coil yachitsulo ya kaboni, yomwe imagwira ntchito bwino kwambiri komanso yotsika mtengo, yakhala chinthu chodziwika bwino pamsika. Kumvetsetsa magawo ake ndi zinthu zake sikofunikira pakugula zisankho komanso ndikofunikira pakukulitsa mtengo wazinthuzo.

M'ntchito ya fakitale, wogwira ntchito yemwe wavala chisoti chotetezera chitetezo cha buluu ndi vest yabuluu akuyang'ana mwachidwi koyilo yachitsulo yotentha yomwe imakwezedwa ndi crane. Powazungulira pali zitsulo zosanjikizana bwino zingapo zopindidwa ndi zitsulo zotentha. Zitsulo zazikuluzikulu zachitsulo ndi malo opangidwa mwadongosolo a fakitale zikuwonetsa kulimba ndi kukhazikika kwa kupanga ndi kukonza zitsulo 环节, zikuwonetsa malo ofunikira a ma koyilo achitsulo otentha ngati chinthu chofunikira pakupanga mafakitale, komanso kumapereka mlengalenga wokhazikika komanso wadongosolo panthawi yantchito ya fakitale.

Chitsulo chachitsulo cha ASTM A36

Kupanga koyilo yachitsulo cha kaboni kumayambirampweya wa carbon steelfakitale, komwe ma billets amasinthidwa kukhala ma coils odziwika bwino kudzera munjira yotentha kwambiri. Mwachitsanzo,ASTM A36 koyilo yachitsulondi kalasi yachitsulo yomwe imagwiritsidwa ntchito nthawi zambiri yotchulidwa ndi American Society for Testing and Materials (ASTM) miyezo ndipo imafunidwa kwambiri m'magawo a zomangamanga ndi zomangamanga. Koyilo ya ASTM A36 ili ndi mphamvu zokolola za ≥250 MPa ndi mphamvu yolimba ya 400-550 MPa, pamodzi ndi ductility ndi weldability, kukwaniritsa zonyamula katundu ndi kulumikiza zofunikira za nyumba zazikulu monga milatho ndi mafelemu a fakitale. Kapangidwe kake kake kamapangitsa kuti mpweya wa kaboni ukhale pansi pa 0.25%, ndikuwongolera mphamvu ndi kulimba kwinaku ndikupewa kutulutsa komwe kumakhudzana ndi mpweya wochuluka.

Kuchokera pamawonedwe a parameter, makulidwe, m'lifupi, ndi kulemera kwa koyilo ndizizindikiro zofunika pakuwunika momwe ma koyilo achitsulo akutentha. Makulidwe wamba amachokera ku 1.2 mpaka 25.4 mm, pomwe m'lifupi amatha kupitilira 2000 mm. Kulemera kwa coil ndikotheka kusinthika, nthawi zambiri kumayambira matani 10 mpaka 30. Kuwongolera molunjika sikumangokhudza kukonza bwino komanso kumakhudzanso kulondola kwa chinthu chomaliza. Mwachitsanzo, kulolerana kwa makulidwe azitsulo zazitsulo zotentha zomwe zimagwiritsidwa ntchito popanga magalimoto kuyenera kuyang'aniridwa mosamalitsa mkati mwa ± 0.05 mm kuti zitsimikizire kusasinthasintha kwa magawo omwe adasindikizidwa.

Zofunikira Zogwirira Ntchito Zopangira Zitsulo Zotentha Zotentha M'mafakitale Osiyanasiyana

Zofunikira pakugwira ntchito kwazitsulo zachitsulo zotentha zimasiyana kwambiri m'mafakitale. Makampani omanga amaika patsogolo mphamvu ndi kukana kwa nyengo, pamene makampani opanga makina amaika patsogolo machinability ndi kutha kwa pamwamba. Chifukwa chake, opanga ma coil a carbon steel ayenera kusintha njira zawo zopangira kuti zigwirizane ndi zosowa za makasitomala. Mwachitsanzo, njira zodzigudubuza zoyendetsedwa bwino ndi kuziziritsa zitha kugwiritsidwa ntchito kukhathamiritsa kapangidwe ka tirigu, kapena ma alloying atha kuwonjezeredwa kuti awonjezere zinthu zina. Mwachitsanzo, pamakoyilo omwe amagwiritsidwa ntchito m'malo okhala ndi chinyezi chambiri, kuwonjezera zinthu monga phosphorous ndi mkuwa kumatha kukulitsa kukana kwa dzimbiri mumlengalenga.

Kuchokera pakupanga makina opangira ma coil a kaboni mpaka pazofunikira za wogwiritsa ntchito womaliza, magawo apakati ndi katundu wa koyilo yachitsulo yotentha zimalumikizidwa munthawi yonseyi. Kaya mukugula ma coil achitsulo mochulukira kapena kusankha ma coils a ASTM A36 enieni, kumvetsetsa mozama za zinthu zakuthupi ndikofunikira kuti mukwaniritse bwino pakati pa magwiridwe antchito ndi mtengo, kuyala maziko olimba a chitukuko chapamwamba pamafakitale osiyanasiyana.

Zithunzi zingapo zikuwonetsa zochitika zosiyanasiyana zamakoyilo azitsulo zotentha

Nkhani yomwe ili pamwambayi ikukhudza magawo ofunikira ndi mfundo zogwirira ntchito za koyilo yachitsulo yotentha. Ngati mukufuna kuwona zosintha kapena zina, chonde ndidziwitseni.
