Nkhani - Magawo Aakulu ndi Katundu wa Coil Yachitsulo Yotentha: Kuyambira Kupanga Mpaka Kugwiritsa Ntchito

M'makampani akuluakulu a zitsulo,chozungulira chachitsulo chotenthaimagwira ntchito ngati maziko, yomwe imagwiritsidwa ntchito kwambiri m'magawo monga zomangamanga, kupanga makina, ndi makampani opanga magalimoto. Chophimba chachitsulo cha kaboni, chomwe chimagwira ntchito bwino kwambiri komanso chotsika mtengo, chakhala chinthu chofunikira kwambiri pamsika. Kumvetsetsa magawo ake ofunikira ndi makhalidwe ake sikuti ndikofunikira kokha pakupanga zisankho zogulira komanso ndikofunikira kwambiri pakukweza mtengo wa chinthucho.

Mu ntchito ya fakitale, wogwira ntchito atavala chisoti chabuluu chachitetezo ndi jekete labuluu akuyang'ana mosamala chozungulira chachitsulo chotenthedwa chikukwezedwa ndi crane. Chozungulira iwo chili ndi ma coil ambiri achitsulo chotenthedwa bwino. Ma coil akuluakulu achitsulo ndi malo okonzedwa bwino a fakitale zimasonyeza kulimba ndi kukhazikika kwa kupanga ndi kukonza zitsulo, zikuwonetsa malo ofunikira a ma coil achitsulo chotenthedwa ngati chinthu chofunikira kwambiri popanga mafakitale, komanso zimasonyeza mkhalidwe wokhwima komanso wadongosolo panthawi ya ntchito za fakitale.

Chophimba chachitsulo cha ASTM A36

Kupanga koyilo yachitsulo cha kaboni kumayamba pakoyilo yachitsulo cha kabonifakitale, komwe ma billet amakonzedwa kukhala ma coil azinthu zinazake kudzera mu njira yozungulira yotentha kwambiri. Mwachitsanzo,Choyikira chachitsulo cha ASTM A36Ndi chitsulo chomwe chimagwiritsidwa ntchito kwambiri chomwe chimafotokozedwa ndi miyezo ya American Society for Testing and Materials (ASTM) ndipo chimafunidwa kwambiri m'magawo omanga ndi zomangamanga. ASTM A36 coil ili ndi mphamvu yotulutsa ya ≥250 MPa ndi mphamvu yokoka ya 400-550 MPa, komanso kusinthasintha kwabwino komanso kusinthasintha, kukwaniritsa zofunikira zonyamula katundu ndi kulumikizana kwa nyumba zazikulu monga milatho ndi mafelemu a fakitale. Kapangidwe kake ka mankhwala nthawi zambiri kamasunga kuchuluka kwa kaboni pansi pa 0.25%, kulinganiza bwino mphamvu ndi kulimba pomwe kumapewa kusokonekera komwe kumakhudzana ndi kuchuluka kwa kaboni.

Kuchokera pamalingaliro a parameter, makulidwe, m'lifupi, ndi kulemera kwa coil ndi zizindikiro zofunika kwambiri poyesa momwe ma coil achitsulo opindidwa ndi hot-rolled. Makulidwe ofanana amakhala pakati pa 1.2 ndi 25.4 mm, pomwe m'lifupi mwake amatha kupitirira 2000 mm. Kulemera kwa coil kumatha kusinthidwa, nthawi zambiri kumakhala pakati pa matani 10 mpaka 30. Kuwongolera kolondola sikumangokhudza magwiridwe antchito a processing komanso kumakhudza mwachindunji kulondola kwa chinthu chomaliza. Mwachitsanzo, kulekerera makulidwe a ma coil achitsulo opindidwa ndi hot-rolled omwe amagwiritsidwa ntchito popanga magalimoto kuyenera kulamulidwa mosamalitsa mkati mwa ± 0.05 mm kuti zitsimikizire kuti magawo osindikizidwa ali ndi miyeso yofanana.

Zofunikira pa Magwiridwe Abwino a Ma Coil a Chitsulo Otentha M'mafakitale Osiyanasiyana

Zofunikira pakugwira ntchito kwa ma coil achitsulo otenthedwa zimasiyana kwambiri m'mafakitale osiyanasiyana. Makampani omanga amaika patsogolo mphamvu ndi kukana nyengo, pomwe makampani opanga makina amaika patsogolo makina ndi kumaliza pamwamba. Chifukwa chake, opanga ma coil achitsulo cha kaboni ayenera kusintha njira zawo zopangira kuti zigwirizane ndi zosowa za makasitomala. Mwachitsanzo, njira zowongolera zozungulira ndi kuziziritsa zingagwiritsidwe ntchito kukonza kapangidwe ka tirigu, kapena zinthu zophatikiza zitha kuwonjezeredwa kuti ziwonjezere mawonekedwe enaake. Mwachitsanzo, pa ma coil omwe amagwiritsidwa ntchito m'malo omwe ali ndi chinyezi chambiri, kuwonjezera zinthu monga phosphorous ndi mkuwa kumatha kuwonjezera kukana dzimbiri mumlengalenga.

Kuyambira pakupanga kwa wopanga coil yachitsulo cha kaboni mpaka zofunikira za wogwiritsa ntchito, magawo ofunikira ndi mawonekedwe a coil yachitsulo chotenthedwa zimalumikizana mu unyolo wonse woperekera. Kaya mukugula coil yachitsulo chochuluka kapena kusankha coils za ASTM A36, kumvetsetsa bwino za mawonekedwe azinthu ndikofunikira kwambiri kuti mupeze mgwirizano wabwino pakati pa magwiridwe antchito ndi mtengo, ndikuyika maziko olimba a chitukuko chapamwamba m'mafakitale osiyanasiyana.

Zithunzi zingapo zikuwonetsa zochitika zosiyanasiyana zogwiritsira ntchito ma coil achitsulo otenthedwa

Nkhani yomwe ili pamwambapa ikufotokoza magawo ofunikira ndi momwe coil yachitsulo chotenthedwa ndi moto imagwirira ntchito. Ngati mukufuna kuwona zosintha kapena zina zowonjezera, chonde ndidziwitseni.
